A total of 2 key IDs can be registered. • Driver seat control unit receives door unlock signal and key ID signal from BCM when driver side door is unlocked using Intelligent Key or driver side door request switch. • Driver seat control unit automatically adjusts driver seat and door mirror to the driving position according to key ID. Driver seat performs turnout position and sets to standby status. • In standby status, when ignition switch is operated from OFF to ACC, return operation sets driver seat to the registered position. NOTE: • When another key ID is newly registered to a key switch to which a key ID is already registered, the previously registered key ID is overwritten and becomes unusable. • When starter signal turns ON during return operation, the operation is interrupted, starter signal turns from ON to OFF, and operation restarts. • Further information for Intelligent Key interlock function.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000007732195 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front D air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: E Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by BR an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag G Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Procedure without Cowl Top Cover I J K INFOID:0000000007732196 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc to prevent damage to windshield. L M N PIIB3706J Precaution for Brake System WARNING: Since dust covering the front and rear brakes has an affect on human body, the dust must be removed with a dust collector.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Power Generation Voltage Variable Control System I J K INFOID:0000000007494994 CAUTION: L For thailand model, the battery current sensor that is installed to the battery cable at the negative terminal measures the charging/discharging current of the battery, and performs various controls. If the electrical component or the ground wire is connected directly to the battery terminal, the current other than that being measured with the battery current sensor is charging to or discharging from the bat- CHG tery. This condition causes the malfunction of the control, and then the battery discharge may occur. Do not connect the electrical component or the ground wire directly to the battery terminal.

Refer to PCS-4, "IPDM E/R : Component Parts Location". ECM Battery current sensor detects the charging/discharging current of the battery. ECM judges the battery condition based on this signal. ECM judges whether to perform the power generation voltage variable control according to the battery condition. When performing the power generation voltage variable control, ECM calculates the target power generation voltage according to the battery condition and sends the calculated value as the power generation command value signal to IPDM E/R. Refer to EC-15, "ENGINE CONTROL SYSTEM : Component Parts Location". 3. Alternator (IC voltage regulator) IC voltage regulator controls the power generation voltage by the target power generation voltage based on the received power generation command signal. When there is no power generation command signal, the alternator performs the normal power generation according to the characteristic of the IC voltage regulator. 4. Battery current sensor (with battery temperature sensor) Battery current sensor is installed to the battery cable at the negative terminal, and it detects the charging/discharging current of the battery and sends the voltage signal to ECM according to the current value. 1. 2.

Always keep the rear bumper near the side radar clean. Do not attach a sticker (including transparent material), install an accessory or paintwork near the side radar. Do not strike or damage the areas around the side radar. Do not strike, damage, and scratch the side radar, especially the vent seal (gray circular) area, under repair. PRECAUTIONS FOR BLIND SPOT WARNING • The BSW system is not a replacement for proper driving procedure and are not designed to prevent contact with vehicles or objects. When changing lanes, always use the side and rear mirrors and turn and look in the direction driver will move to ensure it is safe to change lanes. Never rely solely on the BSW system. • The BSW system may not provide a warning for vehicles that pass through the detection zone quickly. • Do not use the BSW system when towing a trailer because the system may not function properly. • Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard. • The side radar may not be able to detect and activate BSW when certain objects are present such as: - Pedestrians, bicycles, animals. - Several types of vehicles such as motorcycles. - Oncoming vehicles. - Vehicles remaining in the detection zone when driver accelerate from a stop. - A vehicle merging into an adjacent lane at a speed approximately the same as vehicle. - A vehicle approaching rapidly from behind. - A vehicle which vehicle overtakes rapidly. • Severe weather or road spray conditions may reduce the ability of the side radar to detect other vehicles. • The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may detect vehicles driving two lanes away. • The side radar are designed to ignore most stationary objects, however objects such as guardrails, walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.

When changing lanes, always use the side and rear mirrors and turn and look in the direction driver will move to ensure it is safe to change lanes. Never rely solely on the BSW system. • The BSW system may not provide a warning for vehicles that pass through the detection zone quickly. • Do not use the BSW system when towing a trailer because the system may not function properly. • Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard. • The side radar may not be able to detect and activate BSW when certain objects are present such as: - Pedestrians, bicycles, animals. - Several types of vehicles such as motorcycles. - Oncoming vehicles. - Vehicles remaining in the detection zone when driver accelerate from a stop. - A vehicle merging into an adjacent lane at a speed approximately the same as vehicle. - A vehicle approaching rapidly from behind. - A vehicle which vehicle overtakes rapidly. • Severe weather or road spray conditions may reduce the ability of the side radar to detect other vehicles. • The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may detect vehicles driving two lanes away. • The side radar are designed to ignore most stationary objects, however objects such as guardrails, walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precautions for Drive Shaft INFOID:0000000007495703 • - Observe the following precautions when disassembling and assembling drive shaft. Never disassemble joint sub-assembly because it is non-overhaul parts. Perform work in a location which is as dust-free as possible. Clean the parts, before disassembling and assembling. Prevent the entry of foreign objects during disassembly of the service location. Reassemble disassembled parts carefully in the correct order. If work is interrupted, a clean cover must be placed over parts. - Use paper waste. Fabric shop cloths must not be used because of the danger of lint adhering to parts. - Clean disassembled parts (except for rubber parts) with kerosene which shall be removed by blowing with air or wiping with paper waste.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Procedure without Cowl Top Cover INFOID:0000000007495800 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc to prevent damage to windshield. PIIB3706J Precautions for Suspension INFOID:0000000007495801 • When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires on ground. Spilled oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil. - Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions. • After servicing suspension parts, be sure to check wheel alignment. • Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled, tighten as they are.

Replace suspect parts if a malfunction is detected. • Kingpin inclination angle is reference value, no inspection is required. Measure wheel alignment under unladen conditions. NOTE: “Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions. PRELIMINARY CHECK Check the following: • Tires for improper air pressure and wear. Refer to WT-48, "Tire Air Pressure". • Road wheels for runout. • Wheel bearing axial end play. Refer to FAX-6, "Inspection". • Transverse link ball joint axial end play. Refer to FSU-5, "Inspection". • Strut operation. • Each mounting part of axle and suspension for looseness and deformation. • Each of suspension member, strut assembly and transverse link for cracks, deformation and other damage. • Vehicle height (posture). GENERAL INFORMATION AND RECOMMENDATIONS • A four-wheel thrust alignment should be performed. - This type of alignment is recommended for any NISSAN/INFINITI vehicle. - The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is centered. - The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle. - The rack should be checked to ensure that it is level. • Check the machine is properly calibrated. - Your alignment equipment should be regularly calibrated in order to give correct information. - Check with the manufacturer of your specific equipment for their recommended Service/Calibration Schedule. ALIGNMENT PROCESS IMPORTANT: Use only the alignment specifications listed in this Service Manual. • When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Never use these indicators. - The alignment specifications programmed into your machine that operate these indicators may not be correct. - This may result in an ERROR. • Most camera-type alignment machines are equipped with both “Rolling Compensation” method and optional “Jacking Compensation” method to “compensate” the alignment targets or head units. “Rolling Compensation” is the preferred method. - If using the “Rolling Compensation” method, after installing the alignment targets or head units, push or pull on the rear wheel to move the vehicle. Do not push or pull on the vehicle body. - If using the “Jacking Compensation” method, after installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways. NOTE: Do not use the “Rolling Compensation” method if you are using sensor-type alignment equipment. - Follow all instructions for the alignment machine you're using for more information.

The fol- Revision: 2011 September GI-42 2012 QUEST SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident. GI The section is broken into the six following topics: • Vehicle vibration • Heat sensitive • Freezing • Water intrusion • Electrical load • Cold or hot start up Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem. VEHICLE VIBRATION The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustration. Connector & Harness Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection. Hint Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system. Sensor & Relay Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate a loose or poorly mounted sensor or relay. B C D E F G H I J K L SGI839 Engine Compartment There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are: • Connectors not fully seated. • Wiring harness not long enough and is being stressed due to engine vibrations or rocking. • Wires laying across brackets or moving components. • Loose, dirty or corroded ground wires. • Wires routed too close to hot components. To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground Inspection described later.) First check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity. Behind the Instrument Panel An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw. Under Seating Areas Revision: 2011 September GI-43 2012 QUEST M N O P SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or pinching. HEAT SENSITIVE • The customer's concern may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitive condition. • To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent. CAUTION: Never heat components above 60°C (140°F). • If incident occurs while heating the unit, either replace or properly insulate the component. JPAIA0733GB FREEZING • The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water freezing somewhere in the wiring/electrical system. • There are two methods to check for this. The first is to arrange for the owner to leave his car overnight. Check it will get cold enough to demonstrate his complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected. • The second method is to put the suspect component into a freezer long enough for any water to freeze. Reinstall the part into the car and check for the reoccurrence of the incident. If it occurs, repair or replace the component. SGI843 WATER INTRUSION The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car wash. CAUTION: Never spray water directly on any electrical components. SGI844 ELECTRICAL LOAD The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window defogger, radio, fog lamps) turned on. SGI845 COLD OR HOT START UP On some occasions an electrical incident may occur only when the car is started cold, or it may occur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagnosis. Revision: 2011 September GI-44 2012 QUEST SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > Circuit Inspection INFOID:0000000007492185 GI DESCRIPTION • In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure. • You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this. OPEN A circuit is open when there is no continuity through a section of the circuit. B C D There are two types of shorts. SHORT • SHORT CIRCUIT When a circuit contacts another circuit and causes the normal resistance to change. • SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit. NOTE: Refer to GI-39, "How to Check Terminal" to probe or check terminal. E F TESTING FOR “OPENS” IN THE CIRCUIT Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your working knowledge of the system. G H I J SGI846-A Continuity Check Method The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Check to always start with the DMM at the highest resistance level. To help in understanding the diagnosis of open circuits, please refer to the previous schematic. • Disconnect the battery negative cable. • Start at one end of the circuit and work your way to the other end. (At the fuse block in this example) • Connect one probe of the DMM to the fuse block terminal on the load side. • Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point A) • Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B) • Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point C) Any circuit can be diagnosed using the approach in the previous example. Voltage Check Method To help in understanding the diagnosis of open circuits please refer to the previous schematic. In any powered circuit, an open can be found by methodically checking the system for the presence of voltage. This is done by switching the DMM to the voltage function. • Connect one probe of the DMM to a known good ground. • Begin probing at one end of the circuit and work your way to the other end. • With SW1 open, probe at SW1 to check for voltage. voltage: open is further down the circuit than SW1. Revision: 2011 September GI-45 2012 QUEST K L M N O P SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > no voltage: open is between fuse block and SW1 (point A). • Close SW1 and probe at relay. voltage: open is further down the circuit than the relay. no voltage: open is between SW1 and relay (point B). • Close the relay and probe at the solenoid. voltage: open is further down the circuit than the solenoid. no voltage: open is between relay and solenoid (point C). Any powered circuit can be diagnosed using the approach in the previous example. TESTING FOR “SHORTS” IN THE CIRCUIT To simplify the discussion of shorts in the system, please refer to the following schematic. SGI847-A Resistance Check Method • Disconnect the battery negative cable and remove the blown fuse. • Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse. • Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known good ground. • With SW1 open, check for continuity. continuity: short is between fuse terminal and SW1 (point A). no continuity: short is further down the circuit than SW1. • Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. continuity: short is between SW1 and the relay (point B). no continuity: short is further down the circuit than the relay. • Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. continuity: short is between relay and solenoid (point C). no continuity: check solenoid, retrace steps. Voltage Check Method • Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid disconnected) powered through the fuse. • Turn the ignition switch to the ON or START position. Verify battery voltage at the battery + side of the fuse terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground). • With SW1 open and the DMM leads across both fuse terminals, check for voltage. voltage: short is between fuse block and SW1 (point A). no voltage: short is further down the circuit than SW1. • With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for voltage. voltage: short is between SW1 and the relay (point B). no voltage: short is further down the circuit than the relay. • With SW1 closed, relay contacts jumped with fused jumper wire check for voltage. voltage: short is down the circuit of the relay or between the relay and the disconnected solenoid (point C). no voltage: retrace steps and check power to fuse block. GROUND INSPECTION • Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works. • Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even when the ground connection looks clean, there can be a thin film of rust on the surface. Revision: 2011 September GI-46 2012 QUEST SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > • When inspecting a ground connection follow these rules: - Remove the ground bolt or screw. GI - Inspect all mating surfaces for tarnish, dirt, rust, etc. - Clean as required to assure good contact. - Reinstall bolt or screw securely. B - Inspect for “add-on” accessories which may be interfering with the ground circuit. - If several wires are crimped into one ground eyelet terminal, check for proper crimps. Check all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eyelet check no ground wires have excess wire insulation. C • For detailed ground distribution information, refer to “Ground Distribution” in PG section. D E F G H SGI853 I VOLTAGE DROP TESTS • Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when the circuit is in operation. • Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop. • Unwanted resistance can be caused by many situations as follows: - Undersized wiring (single strand example) - Corrosion on switch contacts - Loose wire connections or splices. • If repairs are needed always use wire that is of the same or larger gauge. Measuring Voltage Drop — Accumulated Method • Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the DMM should be closer to power and the negative lead closer to ground. • Operate the circuit. • The DMM will indicate how many volts are being used to “push” current through that part of the circuit. J K L M N O P Revision: 2011 September GI-47 2012 QUEST SERVICE INFORMATION FOR ELECTRICAL INCIDENT < BASIC INSPECTION > Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb. SGI974 Measuring Voltage Drop — Step-by-Step • The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in “Computer Controlled Systems”). • Circuits in the “Computer Controlled System” operate on very low amperage. • The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion. • The step by step voltage drop test can identify a component or wire with too much resistance.

Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Procedure without Cowl Top Cover INFOID:0000000007495992 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc to prevent damage to windshield. PIIB3706J Handling for Adhesive and Primer INFOID:0000000007495993 • Do not use an adhesive which is past its usable date. Shelf life of this product is limited to six months after the date of manufacture. Carefully adhere to the expiration or manufacture date printed on the box. • Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator. • Open the seal of the primer and adhesive just before application. Discard the remainder. • Before application, be sure to shake the primer container to stir the contents. If any floating material is found, do not use it. • If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with soap. • When using primer and adhesive, always observe the precautions in the instruction manual.

Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any customer comments. Refer to GW-8, "Diagnostic Worksheet". This information is necessary to duplicate the conditions that exist when the noise occurs. • The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain all the facts and conditions that exist when the noise occurs (or does not occur). • If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is concerned about. This can be accomplished by performing a test drive with the customer. • After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics are provided so that the customer, service adviser, and technician use the same language when describing the noise. • Squeak – (Like tennis shoes on a clean floor) Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard surfaces = high-pitched noise / softer surfaces = low-pitched noises / edge to surface = chirping • Creak – (Like walking on an old wooden floor) Creak characteristics include firm contact / slow movement/twisting with a rotational movement / pitch dependent on materials / often brought on by activity. • Rattle – (Like shaking a baby rattle) Rattle characteristics include fast repeated contact / vibration or similar movement / loose parts/missing clip or fastener / incorrect clearance. • Knock – (Like a knock on a door) Knock characteristics include hollow sounds / sometimes repeating / often brought on by driver action. • Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver action or road conditions. • Thump – (Heavy, muffled knock noise) Thump characteristics include softer knock / dull sounds often brought on by activity. • Buzz – (Like a bumblebee) Buzz characteristics include high frequency rattle / firm contact. • Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may judge as acceptable may be very irritating to a customer. • Weather conditions, especially humidity and temperature, may have a great effect on noise level. DUPLICATE THE NOISE AND TEST DRIVE Revision: 2011 September GW-4 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES < SYMPTOM DIAGNOSIS > If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to duplicate the same conditions when the repair is reconfirmed. If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following items: 1) Close a door. 2) Tap or push/pull around the area where the noise appears to be coming from. 3) Rev the engine. 4) Use a floor jack to recreate vehicle “twist”. 5) At idle, apply engine load (electrical load, half-clutch on M/T models, drive position on A/T models). 6) Raise the vehicle on a hoist and hit a tire with a rubber hammer. • Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs. • If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the vehicle body. CHECK RELATED SERVICE BULLETINS After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related to the concern or symptom. If a TSB relates to the symptom, follow the procedure to repair the noise. LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis ear: J-39570, engine ear, and mechanics stethoscope). 2. Narrow down the noise to a more specific area and identify the cause of the noise by: • Removing the component(s) in the area that is / are suspected to be the cause of the noise. Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken or lost during the repair, resulting in the creation of new noise. • Tapping or pushing/pulling the component(s) that is / are suspected to be the cause of the noise. Do not tap or push/pull the component(s) with excessive force, otherwise the noise is eliminated only temporarily. • Feeling for a vibration by hand by touching the component(s) that is / are suspected to be the cause of the noise. • Placing a piece of paper between components that are suspected to be the cause of the noise. • Looking for loose components and contact marks. Refer to GW-6, "Inspection Procedure". A B C D E F 1. H I J GW REPAIR THE CAUSE • • - If the cause is a loose component, tighten the component securely. If the cause is insufficient clearance between components: Separate components by repositioning or loosening and retightening the components, if possible. Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape, or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through the authorized NISSAN Parts Department. CAUTION: Never use excessive force as many components are constructed of plastic and may be damaged. NOTE: Always check with the Parts Department for the latest parts information.

CONFIRM THE REPAIR After repair is complete, test drive the vehicle to confirm that the cause of noise is repaired by test driving the vehicle. Operate the vehicle under the same conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet. Inspection Procedure INFOID:0000000007495997 Refer to Table of Contents for specific component removal and installation information. INSTRUMENT PANEL Most incidents are caused by contact and movement between: 1. The cluster lid A and instrument panel 2. Acrylic lens and combination meter housing 3. Instrument panel to front pillar garnish 4. Instrument panel to windshield 5. Instrument panel mounting pins 6. Wiring harnesses behind the combination meter 7. A/C defroster duct and duct joint These incidents can usually be located by tapping or moving the components to duplicate the noise or by pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness. CAUTION: Never use silicone spray to isolate a squeak or rattle. If the area is saturated with silicone, the recheck of repair becomes impossible. CENTER CONSOLE Components to check include: 1. Shifter assembly cover to finisher 2. A/C control unit and cluster lid C 3. Wiring harnesses behind audio and A/C control unit The instrument panel repair and isolation procedures also apply to the center console. DOORS Check the following items: 1. Finisher and inner panel making a slapping noise 2. Inside handle escutcheon connection to door finisher 3. Wiring harnesses tapping 4. Door striker out of alignment causing a popping noise on starts and stops Tapping, moving the components, or pressing on them while driving to duplicate the conditions can isolate many of these incidents. The areas can usually be insulated with felt cloth tape or insulator foam blocks from the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise. TRUNK Trunk noises are often caused by a loose jack or loose items put into the trunk by the customer. In addition check for the following items: Revision: 2011 September GW-6 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES < SYMPTOM DIAGNOSIS > 1. Trunk lid dumpers out of adjustment 2. Trunk lid striker out of adjustment 3. Trunk lid torsion bars knocking together 4. A loose license plate or bracket Most of these incidents can be repaired by adjusting, securing, or insulating the item(s) or component(s) causing the noise. SUNROOF/HEADLINING Noises in the sunroof / headlining area can often be traced to one of the following items: 1. Sunroof lid, rail, linkage, or seals making a rattle or light knocking noise 2. Sunvisor shaft shaking in the holder 3. Front or rear windshield touching headlining and squeaking Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these incidents. Repairs usually consist of insulating with felt cloth tape. A B C D E SEATS When isolating seat noise it is important to note the position the seat is in and the load placed on the seat when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the noise. Causes of seat noise include: 1. Headrest rods and holder 2. A squeak between the seat pad cushion and frame 3. The rear seatback lock and bracket These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component or applying urethane tape to the contact area. F G H I UNDERHOOD Some interior noise may be caused by components under the hood or on the engine wall. The noise is then transmitted into the passenger compartment. J Causes of transmitted underhood noise include: 1. Any component mounted to the engine wall 2. Components that pass through the engine wall GW 3. Engine wall mounts and connectors 4. Loose radiator mounting pins 5. Hood bumpers out of adjustment L 6.

Revision: 2011 September MA-10 2012 QUEST RECOMMENDED FLUIDS AND LUBRICANTS < PERIODIC MAINTENANCE > WARNING: • Never remove the radiator or coolant reservoir cap when the engine is hot. Wait until the engine and radiator cool down. Serious burns could be caused by high pressure fluid escaping from the radiator. See precautions in “If your vehicle overheats” found in the “In case of emergency” section of this manual. • The radiator is equipped with a pressure type radiator cap. To prevent engine damage, use only a genuine NISSAN radiator cap. CAUTION: • When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent. Genuine NISSAN Long Life Antifreeze/Coolant (blue) is pre-diluted to provide antifreeze protection to -34°F (-37°C). If additional freeze protection is needed due to weather where you operate your vehicle, add Genuine NISSAN Long Life Antifreeze/Coolant (blue) concentrate following the directions on the container. If an equivalent coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) is used, follow the coolant manufacture's instructions to maintain minimum antifreeze protection to -34°F (-37°C). The use of other types of coolant solutions other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent may damage the engine cooling system. • The life expectancy of the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other type of coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue), including Genuine NISSAN Long Life Antifreeze/Coolant (green), or the use of non-distilled water will reduce the life expectancy of the factory-fill coolant.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any of H customer's comments; refer to MIR-21, "Diagnostic Worksheet". This information is necessary to duplicate the conditions that exist when the noise occurs. • The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain I all the facts and conditions that exist when the noise occurs (or does not occur). • If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is concerned about. This can be accomplished by performing a cruise test on the vehicle with the customer. • After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics J are provided so the customer, service adviser and technician are all speaking the same language when defining the noise. • Squeak —(Like tennis shoes on a clean floor) K Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping • Creak—(Like walking on an old wooden floor) Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch depen- MIR dent on materials/often brought on by activity. • Rattle—(Like shaking a baby rattle) Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing M clip or fastener/incorrect clearance. • Knock —(Like a knock on a door) Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action. N • Tick—(Like a clock second hand) Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver action or road conditions. • Thump—(Heavy, muffled knock noise) O Thump characteristics include softer knock/dead sound often brought on by activity. • Buzz—(Like a bumblebee) Buzz characteristics include high frequency rattle/firm contact. • Often the degree of acceptable noise level will vary depending up on the person. A noise that you may judge P as acceptable may be very irritating to the customer. • Weather conditions, especially humidity and temperature, may have a great effect on noise level. DUPLICATE THE NOISE AND TEST DRIVE If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to duplicate the same conditions when you confirm the repair. Revision: 2011 September MIR-17 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES [WITH ADP] < SYMPTOM DIAGNOSIS > If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following: 1) Close a door. 2) Tap or push/pull around the area where the noise appears to be coming from. 3) Rev the engine. 4) Use a floor jack to recreate vehicle “twist”. 5) At idle, apply engine load (electrical load, half-clutch on M/T models, drive position on A/T models). 6) Raise the vehicle on a hoist and hit a tire with a rubber hammer. • Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs. • If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the vehicle body. CHECK RELATED SERVICE BULLETINS After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related to that concern or symptom. If a TSB relates to the symptom, follow the procedure to repair the noise. LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE 1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis Ear: J-39570, Engine Ear and mechanics stethoscope). 2. Narrow down the noise to a more specific area and identify the cause of the noise by: • removing the components in the area that you suspect the noise is coming from. Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken or lost during the repair, resulting in the creation of new noise. • tapping or pushing/pulling the component that you suspect is causing the noise. Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only temporarily. • feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the noise. • placing a piece of paper between components that you suspect are causing the noise. • looking for loose components and contact marks. Refer to MIR-19, "Inspection Procedure". REPAIR THE CAUSE • • - If the cause is a loose component, tighten the component securely. If the cause is insufficient clearance between components: separate components by repositioning or loosening and retightening the component, if possible. insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts Department. CAUTION: Do not use excessive force as many components are constructed of plastic and may be damaged. NOTE: Always check with the Parts Department for the latest parts information. The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be ordered separately as needed. URETHANE PADS [1.5 mm (0.059 in) thick] Insulates connectors, harness, etc. 76268-9E005: 100 × 135 mm (3.94 × 5.31 in)/76884-71L01: 60 × 85 mm (2.36 × 3.35 in)/7688471L02:15 × 25 mm (0.59 × 0.98 in) INSULATOR (Foam blocks) Insulates components from contact.

Operate the vehicle under the same conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet. Inspection Procedure INFOID:0000000007492256 C D Refer to Table of Contents for specific component removal and installationinformation. INSTRUMENT PANEL E Most incidents are caused by contact and movement between: 1. The cluster lid A and instrument panel 2. Acrylic lens and combination meter housing 3. Instrument panel to front pillar garnish 4. Instrument panel to windshield 5. Instrument panel mounting pins 6. Wiring harnesses behind the combination meter 7. A/C defroster duct and duct joint These incidents can usually be located by tapping or moving the components to duplicate the noise or by pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness. CAUTION: Do not use silicone spray to isolate a squeak or rattle. If you saturatethe area with silicone, you will not be able to recheck the repair. F G H I J CENTER CONSOLE Components to pay attention to include: 1. Shifter assembly cover to finisher 2. A/C control unit and cluster lid C 3. Wiring harnesses behind audio and A/C control unit The instrument panel repair and isolation procedures also apply to thecenter console. K MIR DOORS Pay attention to the: 1. Finisher and inner panel making a slapping noise 2. Inside handle escutcheon to door finisher 3. Wiring harnesses tapping 4. Door striker out of alignment causing a popping noise on startsand stops Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from the Nissan Squeak and Rattle Kit (J-43980) to repair the noise. TRUNK MIR-19 N O P Trunk noises are often caused by a loose jack or loose items put intothe trunk by the owner. In addition look for: 1. Trunk lid dumpers out of adjustment 2. Trunk lid striker out of adjustment 3. The trunk lid torsion bars knocking together 4. A loose license plate or bracket Revision: 2011 September M 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES [WITH ADP] < SYMPTOM DIAGNOSIS > Most of these incidents can be repaired by adjusting, securing or insulatingthe item(s) or component(s) causing the noise. SUNROOF/HEADLINING Noises in the sunroof/headlining area can often be traced to one of the following: 1. Sunroof lid, rail, linkage or seals making a rattle or light knockingnoise 2. Sunvisor shaft shaking in the holder 3. Front or rear windshield touching headlining and squeaking Again, pressing on the components to stop the noise while duplicatingthe conditions can isolate most of these incidents. Repairs usually consistof insulating with felt cloth tape. SEATS When isolating seat noise it's important to note the position the seatis in and the load placed on the seat when the noise is present. These conditionsshould be duplicated when verifying and isolating the cause of the noise. Cause of seat noise include: 1. Headrest rods and holder 2. A squeak between the seat pad cushion and frame 3. The rear seatback lock and bracket These noises can be isolated by moving or pressing on the suspectedcomponents while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component orapplying urethane tape to the contact area. UNDERHOOD Some interior noise may be caused by components under the hood or onthe engine wall. The noise is then transmitted into the passenger compartment. Causes of transmitted underhood noise include: 1. Any component mounted to the engine wall 2. Components that pass through the engine wall 3. Engine wall mounts and connectors 4. Loose radiator mounting pins 5. Hood bumpers out of adjustment 6. Hood striker out of adjustment These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or insulating the component causing the noise.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer.

Compass display turns to zone variation change mode Press and hold (for more than 9 sec.) Compass display turns to calibration mode • All standard compasses determine direction relative to magnetic north, however, this electronic compass is designed to display direction relative to true north. • The difference between magnetic north and true north varies from place to place across the surface of the earth. • This electronic compass must be “told” approximately where it is on the earth’s surface so that the magnetic north reading can be properly converted into a true north display. • To tell the electronic compass where it’s at, the earth is separated into numbered “Zone Variances”. The zone variance number in which the compass is to function must be entered into this electronic compass. • Each zone is magnetically about 4.2° wide. Typically, anything under a 22.5° total zone change is not noticed on the electronic compass display. However, if a change over 22.5° occurs, a reading may be off by one or more primary directions. • On long trips, the vehicle may leave its original zone and enter one or more new zones. Generally, you do not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vacation. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the vehicle is “permanently” moved to a new location, it is recommended that the compass zone be reset.

However, occasional circumstances may cause the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Calibrate the mirror compass if the display shows only one direction or a limited number of directions. NOTE: • If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle before performing the following steps. Do not put the hat back on the vehicle after the procedure is completed. • Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power lines. • Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and close the doors. 1. Verify the correct compass zone setting for the geographical location. Refer to MWI-56, "Work Procedure". 2. Press and hold the compass switch for more than 9 seconds. 3. “C” is displayed on the compass display when calibration starts. 4. Drive slowly [less than 8 km/h (5 MPH)] in a circle until the “C / CAL” is replaced with primary headings (N, NE, E, SE, S, SW, W, or NW). NOTE: This will require driving at least 2 complete 360 degree circles, 3 complete circles may be required. 5. The compass calibration procedure is now complete. The compass should operate normally. NOTE: If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, repeat the calibration procedure.

It is an on-vehicle multiplex communication system with high data communication speed and excellent error detectability. Many electronic control units are equipped onto vehicles, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with two communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. CAN Communication Signal Chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart".

However, some large changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines, large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While this does not happen very often, it is possible. • During normal operation, the compass mirror will continuously update the compass calibration to adjust for gradual changes in the vehicle's magnetic “remnant” field. If the vehicle is subjected to high magnetic influences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be calibrated. If this occurs, perform the calibration procedure. • If at any time the compass continually displays an incorrect direction or the reading is erratic or locked, verify the correct zone variance. C D E Symptom Chart Symptom Cause Solution / Reference F The compass display reads “C”. Compass shows the wrong direction. Compass does not change direction appears “Locked”. Compass does not show all the directions, one or more is missing. The compass was calibrated but it “loses” calibration. G • Compass is not calibrated. • Incorrect zone variance setting. • Large change in magnetic field (Steel bridges, subways, concentrations of metal, carwashes, etc.) • Compass was calibrated incorrectly or in the presence of a strong magnetic field. Perform Calibration. Refer to MWI-57, "Work Procedure". Perform zone variation setting if correct reading is desired in that location. Refer toMWI-56, "Work Procedure". On long trips the compass shows the wrong direction. H I J INFORMATION DISPLAY INFORMATION DISPLAY : Description INFOID:0000000007495562 K AMBIENT TEMPERATURE The displayed ambient temperature on the information display may differ from the actual temperature because it is a corrected value calculated from the ambient sensor signal by the combination meter. Refer to MWI-21, "INFORMATION DISPLAY : System Description" for details on the correction process. DISTANCE TO EMPTY The calculated distance to empty may differ from the actual distance to empty if the refueling amount is approximately 15 (4 US gal, 3-1/4 Imp gal) or less. This is because the refuel control (moves the fuel gauge needle quicker than normal judging that the driver is refueling the vehicle) is not performing.

[IPDM E/R] < PRECAUTION > PRECAUTION A PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000007492076 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000007495572 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Power Window AUTO-Operation • AUTO UP/DOWN operation can be performed when power window main switch or front power window switch (passenger side) turns to AUTO. • Encoder continues detecting the movement of power window motor and transmits the encoder pulse signal to power window switch while power window motor is operating. • Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at the fully opened/closed position. • Power window motor is operable if encoder is malfunctioning. Retained Power Operation Revision: 2011 September PWC-9 2012 QUEST L M N O P SYSTEM [FRONT WINDOW ANTI-PINCH] < SYSTEM DESCRIPTION > Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF. Retained Power Cancel Conditions • Front door CLOSE (door switch OFF)→OPEN (door switch ON). • When ignition switch is ON. • When timer time passes (45 seconds). Power Window Lock Function Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits each power window switch operation except the power window main switch. Power Window Serial Link • Power window main switch, front power window switch (passenger side), and BCM transmit and receive the signal by power window serial link. • Power window serial link transmits the power window main switch operation signals and retained power signal to power window main switch module and front power window switch (passenger side) module. Anti-Pinch Operation • Pinch foreign matter in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass 150 mm (5.9 in) or for 2 seconds when detected. • Encoder continues detecting the movement of power window motor and transmits to power window switch as the encoder pulse signal while power window motor is operating. • Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass. • Power window switch controls to lower the door glass for 150 mm (5.9 in) after it detects encoder pulse signal frequency change. Operation Condition When front door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the door glass closes and is fully closed). NOTE: Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower. Door Key Cylinder Switch Operation Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5 seconds or more to OPEN or CLOSE front power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL when operating. Operation Conditions • Ignition switch OFF. • Hold door key cylinder to LOCK position for 1.5 seconds or more to perform CLOSE operation of the door glass. • Hold door key cylinder to UNLOCK position for 1.5 seconds or more to perform OPEN operation of the door glass. Keyless Power Window Down Operation Front power windows open when the unlock button on Intelligent Key is activated and kept pressed for more than 3 seconds with the ignition switch OFF. The windows keep opening if the unlock button is continuously pressed. The power window opening stops when the following operations are performed. • When the unlock button is kept pressed more than 15 seconds. • When the ignition switch is turned ON while the power window opening is operated. • When the unlock button is released.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Power Window AUTO-Operation • AUTO UP/DOWN operation can be performed when power window main switch turns to AUTO. • Encoder continues detecting the movement of power window motor and transmits to power window switch as the encoder pulse signal while power window motor is operating. • Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at fully opened/closed position. • Power window motor is operable in case encoder is malfunctioning. Retained Power Operation Retained power operation is an additional power supply function that enables power window system to operate for 45 seconds even when ignition switch is turned OFF. Retained Power Cancel Conditions • Front door CLOSE (door switch OFF) → OPEN (door switch ON). • When ignition switch is ON again. • When timer time passes (45 seconds). Power Window Lock Function Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits each power window switch operation except the power window main switch. Revision: 2011 September PWC-66 2012 QUEST SYSTEM [DRIVER SIDE WINDOW ANTI-PINCH] < SYSTEM DESCRIPTION > Anti-Pinch System • Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass 150 mm (5.9 in) when detected. • Encoder continues detecting the movement of front power window motor (driver side) and transmits to power window main switch as the encoder pulse signal while front power window motor (driver side) is operating. • Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass. • Power window main switch controls to lower the window glass for 150 mm (5.9 in) after it detects encoder pulse signal frequency change. Operation Condition When front door glass (driver side) AUTO-UP operation is performed (anti-pinch function does not operate just before the door glass closes and is fully closed). NOTE: Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower.

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000007495760 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

BELT PRE-TENSIONER" B INFOID:0000000007494922 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any H customer comments. Refer to RF-41, "Diagnostic Worksheet". This information is necessary to duplicate the conditions that exist when the noise occurs. • The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain I all the facts and conditions that exist when the noise occurs (or does not occur). • If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is concerned about. This can be accomplished by performing a test drive with the customer. • After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics J are provided so that the customer, service adviser, and technician use the same language when describing the noise. • Squeak – (Like tennis shoes on a clean floor) RF Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard surfaces = high-pitched noise / softer surfaces = low-pitched noises / edge to surface = chirping • Creak – (Like walking on an old wooden floor) Creak characteristics include firm contact / slow movement/twisting with a rotational movement / pitch L dependent on materials / often brought on by activity. • Rattle – (Like shaking a baby rattle) Rattle characteristics include fast repeated contact / vibration or similar movement / loose parts/missing clip M or fastener / incorrect clearance. • Knock – (Like a knock on a door) Knock characteristics include hollow sounds / sometimes repeating / often brought on by driver action. N • Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver action or road conditions. • Thump – (Heavy, muffled knock noise) O Thump characteristics include softer knock / dull sounds often brought on by activity. • Buzz – (Like a bumblebee) Buzz characteristics include high frequency rattle / firm contact. • Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may P judge as acceptable may be very irritating to a customer. • Weather conditions, especially humidity and temperature, may have a great effect on noise level. DUPLICATE THE NOISE AND TEST DRIVE If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to duplicate the same conditions when the repair is reconfirmed. Revision: 2011 September RF-37 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES < SYMPTOM DIAGNOSIS > If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following items: 1) Close a door. 2) Tap or push/pull around the area where the noise appears to be coming from. 3) Rev the engine. 4) Use a floor jack to recreate vehicle “twist”. 5) At idle, apply engine load (electrical load, half-clutch on M/T models, drive position on A/T models). 6) Raise the vehicle on a hoist and hit a tire with a rubber hammer. • Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs. • If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the vehicle body. CHECK RELATED SERVICE BULLETINS After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related to the concern or symptom. If a TSB relates to the symptom, follow the procedure to repair the noise. LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE 1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis ear: J-39570, engine ear, and mechanics stethoscope). 2. Narrow down the noise to a more specific area and identify the cause of the noise by: • Removing the component(s) in the area that is / are suspected to be the cause of the noise. Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken or lost during the repair, resulting in the creation of new noise. • Tapping or pushing/pulling the component(s) that is / are suspected to be the cause of the noise. Do not tap or push/pull the component(s) with excessive force, otherwise the noise is eliminated only temporarily. • Feeling for a vibration by hand by touching the component(s) that is / are suspected to be the cause of the noise. • Placing a piece of paper between components that are suspected to be the cause of the noise. • Looking for loose components and contact marks. Refer to RF-39, "Inspection Procedure". REPAIR THE CAUSE • • - If the cause is a loose component, tighten the component securely. If the cause is insufficient clearance between components: Separate components by repositioning or loosening and retightening the components, if possible. Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape, or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through the authorized NISSAN Parts Department. CAUTION: Never use excessive force as many components are constructed of plastic and may be damaged. NOTE: Always check with the Parts Department for the latest parts information. The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be ordered separately as needed. URETHANE PADS [1.5 mm (0.059 in) thick] Insulates connectors, harness, etc. • 76268-9E005: 100 × 135 mm (3.937 × 5.315 in) • 76884-71L01: 60 × 85 mm (2.362 × 3.346 in) • 76884-71L02: 15 × 25 mm (0.591 × 0.984 in) INSULATOR (Foam blocks) Insulates components from contact. Can be used to fill space behind a panel. • 73982-9E000: 45 mm (1.772 in) thick, 50 × 50 mm (1.969 × 1.969 in) • 73982-50Y00: 10 mm (0.394 in) thick, 50 × 50 mm (1.969 × 1.969 in) INSULATOR (Light foam block) 80845-71L00: 30 mm (1.181 in) thick, 30 × 50 mm (1.181 × 1.969in) FELT CLOTHTAPE Used to insulate where movement does not occur. Ideal for instrument panel applications. • 68370-4B000: 15 × 25 mm (0.591 × 0.984 in) pad • 68239-13E00: 5 mm (0.197 in) wide tape roll Revision: 2011 September RF-38 2012 QUEST SQUEAK AND RATTLE TROUBLE DIAGNOSES < SYMPTOM DIAGNOSIS > The following materials, not found in the kit, can also be used to repair squeaks and rattles. UHMW (TEFLON) TAPE Insulates where slight movement is present. Ideal for instrument panel applications. SILICONE GREASE Used in place of UHMW tape that is visible or does not fit. Only lasts a few months. SILICONE SPRAY Used when grease cannot be applied. DUCT TAPE Used to eliminate movement. A B C CONFIRM THE REPAIR After repair is complete, test drive the vehicle to confirm that the cause of noise is repaired by test driving the vehicle. Operate the vehicle under the same conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet. Inspection Procedure INFOID:0000000007494965 D E Refer to Table of Contents for specific component removal and installation information. INSTRUMENT PANEL Most incidents are caused by contact and movement between: 1. The cluster lid A and instrument panel 2. Acrylic lens and combination meter housing 3. Instrument panel to front pillar garnish 4. Instrument panel to windshield 5. Instrument panel mounting pins 6. Wiring harnesses behind the combination meter 7. A/C defroster duct and duct joint These incidents can usually be located by tapping or moving the components to duplicate the noise or by pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness. CAUTION: Never use silicone spray to isolate a squeak or rattle. If the area is saturated with silicone, the recheck of repair becomes impossible. CENTER CONSOLE Components to check include: 1. Shifter assembly cover to finisher 2. A/C control unit and cluster lid C 3. Wiring harnesses behind audio and A/C control unit The instrument panel repair and isolation procedures also apply to the center console. F G H I J RF L M DOORS Check the following items: 1. Finisher and inner panel making a slapping noise 2. Inside handle escutcheon connection to door finisher 3. Wiring harnesses tapping 4. Door striker out of alignment causing a popping noise on starts and stops Tapping, moving the components, or pressing on them while driving to duplicate the conditions can isolate many of these incidents. The areas can usually be insulated with felt cloth tape or insulator foam blocks from the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise. TRUNK Trunk noises are often caused by a loose jack or loose items put into the trunk by the customer. In addition check for the following items: 1. Trunk lid dumpers out of adjustment 2. Trunk lid striker out of adjustment Revision: 2011 September RF-39 2012 QUEST N O P SQUEAK AND RATTLE TROUBLE DIAGNOSES < SYMPTOM DIAGNOSIS > 3. Trunk lid torsion bars knocking together 4. A loose license plate or bracket Most of these incidents can be repaired by adjusting, securing, or insulating the item(s) or component(s) causing the noise. SUNROOF/HEADLINING Noises in the sunroof / headlining area can often be traced to one of the following items: 1. Sunroof lid, rail, linkage, or seals making a rattle or light knocking noise 2. Sunvisor shaft shaking in the holder 3. Front or rear windshield touching headlining and squeaking Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these incidents. Repairs usually consist of insulating with felt cloth tape. SEATS When isolating seat noise it is important to note the position the seat is in and the load placed on the seat when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the noise. Causes of seat noise include: 1. Headrest rods and holder 2. A squeak between the seat pad cushion and frame 3. The rear seatback lock and bracket These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component or applying urethane tape to the contact area. UNDERHOOD Some interior noise may be caused by components under the hood or on the engine wall. The noise is then transmitted into the passenger compartment. Causes of transmitted underhood noise include: 1. Any component mounted to the engine wall 2. Components that pass through the engine wall 3. Engine wall mounts and connectors 4. Loose radiator mounting pins 5. Hood bumpers out of adjustment 6. Hood striker out of adjustment These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best method is to secure, move, or insulate one component at a time and test drive the vehicle. Also, engine RPM or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or insulating the component causing the noise.

GENERAL INFORMATION AND RECOMMENDATIONS • A four-wheel thrust alignment should be performed. - This type of alignment is recommended for any NISSAN/INFINITI vehicle. - The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is centered. - The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle. - The rack should be checked to ensure that it is level. • Make sure the machine is properly calibrated. - Your alignment equipment should be regularly calibrated in order to give correct information. - Check with the manufacturer of your specific equipment for their recommended Service/Calibration Schedule. ALIGNMENT PROCESS IMPORTANT: Use only the alignment specifications listed in this Service Manual. • When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Never use these indicators. - The alignment specifications programmed into your machine that operate these indicators may not be correct. - This may result in an ERROR. • Most camera-type alignment machines are equipped with both “Rolling Compensation” method and optional “Jacking Compensation” method to “compensate” the alignment targets or head units. “Rolling Compensation” is the preferred method. - If using the “Rolling Compensation” method, after installing the alignment targets or head units, push or pull on the rear wheel to move the vehicle. Do not push or pull on the vehicle body. - If using the “Jacking Compensation” method, after installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways. NOTE: Do not use the “Rolling Compensation” method if you are using sensor-type alignment equipment. - Follow all instructions for the alignment machine you're using for more information.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Seat Belt Service INFOID:0000000007492760 CAUTION: • Before removing the front seat belt pre-tensioner assembly, turn the ignition switch off, disconnect battery negative terminal and wait at least 3 minutes. • Do not use electrical test equipment for front seat belt pre-tensioner connector. • After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat belt pre-tensioner connector, check the system function. Refer to SRC-15, "Description". • Do not use disassembled buckle or seat belt assembly. • Replace anchor bolts if they are deformed or worn out. • Never oil tongue and buckle. • If any component of seat belt assembly is questionable, do not repair. Replace the entire seat belt assembly. • If webbing is cut, frayed or damaged, replace seat belt assembly. • When replacing seat belt assembly, use a genuine NISSAN seat belt assembly. AFTER A COLLISION WARNING: Inspect all seat belt assemblies including retractors and attached hardware after any collision. NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioners should be replaced even if the seat belts are not in use during a frontal collision in which the air bags are deployed. Revision: 2011 September SB-2 2012 QUEST PRECAUTIONS < PRECAUTION > Replace any seat belt assembly (including anchor bolts) if: • The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and buckles show no damage and continue to operate properly). • The seat belt was damaged in an accident (i.e. torn webbing, bent retractor or guide). • The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage or distortion and repair as necessary before installing a new seat belt assembly. • Anchor bolts are deformed or worn out. • The front seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in which the air bags are deployed.

SEAT BELT RETRACTOR : Inspection INFOID:0000000007492763 AFTER A COLLISION WARNING: Inspect all seat belt assemblies including retractors and attached hardware after any collision. NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation was noted. Seat belt pre-tensioners should be replaced even if the seat belts were not in use during a frontal collision in which the air bags were deployed. Replace any seat belt assembly (including anchor bolts) if: • The seat belt is in use at the time of a collision (except for minor collisions and the belts, retractors and buckles show no damage and continue to operate properly). • The seat belt is damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.). • The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or distortion and repair if necessary before installing a new seat belt assembly. • Anchor bolts are deformed or worn out. • The seat belt pre-tensioners must be replaced even if the seat belts were not in use during the collision in which the air bags were deployed. PRELIMINARY CHECKS 1. a. b. 2. 3. 4. 5. a. Check the seat belt warning lamp for proper operation as per the following: Turn ignition switch ON. The seat belt warning lamp should illuminate. Fasten driver seat belt. The seat belt warning lamp should turn OFF. If the air bag warning lamp is blinking, perform self-diagnosis with CONSULT and air bag warning lamp. Refer to SRC-15, "Description". Check that the seat belt retractor, seat belt anchor and buckle bolts are tightened firmly. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Check that guide swivels freely and that webbing lays flat and does not bind in guide. Check that height adjuster operates properly and holds securely. Check retractor operation: Fully extend the seat belt webbing and check for twists, tears or other damage. Revision: 2011 September SB-6 2012 QUEST FRONT SEAT BELT < REMOVAL AND INSTALLATION > b. Allow the seat belt to retract. Check that webbing returns smoothly and completely into the retractor. If the seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth. Dirt build-up in the loops of the upper anchors can cause the seat belts to retract slowly. c. Fasten the seat belt. Check that seat belt returns smoothly and completely to the retractor. If the webbing does not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT TAPE SET” and perform the following steps. A B Inspect the front seat belt through-anchor 1. 2. 3. 6. Pull the seat belt out to a length of 500 mm (19.69 in) or more. Fix the seat belt at the center pillar webbing opening with a clip or other device. Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull it tightly while moving it up and down several times along the webbing opening surface to remove dirt stuck there. 4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean cloth. 5. Apply tape at the point where the webbing contacts the through-anchor webbing opening. NOTE: Apply the tape so that there is no slack or wrinkling. 6. Remove the clip fixing the seat belt and check that the webbing returns smoothly. Repeat steps above if necessary to check the other seat belts. SEAT BELT RETRACTOR ON-VEHICLE CHECK C D E F G Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR) NOTE: All seat belt retractors are Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the SB retractor will lock and prevent the webbing from extending any further. All 3-point type seat belt retractors except the driver seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt I is fully extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt in a specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat belt to fully wind back into the retractor. Check the seat belt retractors with the following test(s) to determine if a retractor assembly is operating prop- J erly. ELR Function Stationary Check Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from extending further. K ALR Function Stationary Check 1. 2. 3. 4.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Service INFOID:0000000007494898 • Never use electrical test equipment to check SRS circuits unless instructed to in this Service Manual. • Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3 minutes. For approximately 3 minutes after the battery negative terminal are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, never work on any SRS connectors or wires until at least 3 minutes have elapsed. • Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required. • The spiral cable must be aligned in the neutral position since its rotations are limited. Never turn steering wheel and column after removal of steering gear. • Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and seat mounted front side air bag module standing with the stud bolt side facing down. • Conduct self-diagnosis to check entire SRS for proper functioning after replacing any components. • After air bag inflates, the front instrument panel assembly should be replaced if damaged. • Always replace instrument panel pad following front passenger air bag deployment.

Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000007492778 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Service INFOID:0000000007492779 • Never use electrical test equipment to check SRS circuits unless instructed to in this Service Manual. • Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes or more. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pretensioner to deploy. Therefore, never work on any SRS connectors or wires until at least 3 minutes have passed. • Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required. • The spiral cable must be aligned with the neutral position since its rotations are limited. Never turn steering wheel and column after removal of steering gear. • Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and seat mounted front side air bag module standing with the stud bolt side facing down. • Conduct self-diagnosis to check entire SRS for proper function after replacing any components. • After air bag inflates, the front instrument panel assembly should be replaced if damaged. • Always replace instrument panel pad following front passenger air bag deployment. • Never solder the harness when making repairs. Check that harness is not pinched and that there is no contact with other components. • Never allow harness to come in contact with oil, grease, waste oil, or water. • Never insert foreign materials, such as a screwdriver, into the harness connector. (This is to prevent accidental activation caused by static electricity.) • Always use CONSULT or SRS air bag warning lamp to perform the circuit diagnosis. (Never use an electric tester such as a circuit tester.) Revision: 2011 September SRC-6 2012 QUEST PRECAUTIONS < PRECAUTION > • Never enter in the deployment area of the pop-up roll bar. Never put an object in the deployment area of the pop-up roll bar. (This is to prevent injury in case of an unintentional deployment.) • When handling a pop-up roll bar, always grip the frame and handle carefully. • Never reuse a pop-up roll bar that has previously deployed. • Modification of the pop-up roll bar may cause unintentional deployment or a malfunction. Never disassemble or modify the pop-up roll bar. • Never allow the pop-up roll bar to be impacted (by dropping or otherwise). Always replace the pop-up roll bar if impacted. • When repairing the surrounding area of the pop-up roll bar, be careful not to apply excessive heat when welding or otherwise. Remove the pop-up roll bar in advance, if necessary. Be careful when modifying the mounting area or installing other parts because an incorrect procedure may cause damage or a malfunction. • Never disassemble the pop-up roll bar. • Never expose the pop-up roll bar to temperatures exceeding 90 °C (194 °F). • Never allow oil, grease, detergent, or water to come in contact with the pop-up roll bar.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Service Notice or Precautions for Steering System INFOID:0000000007495857 • In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle condition, and then check wheel alignment. • Observe the following precautions when disassembling. - Before disassembly, thoroughly clean the outside of the unit. - Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter. - For easier and proper assembly, place disassembled parts in order on a parts rack. - Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation. - Never reuse non-reusable parts. - Before assembling, apply the specified grease to the directed parts.

PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000007492022 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front D air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: E Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by F an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag STC Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Service Notice and Precautions for Hydraulic Pump Electric Power Steering System I J K INFOID:0000000007492023 • Check if air pressure and size of tires are proper, the specified part is used for the steering wheel is genuine part. • Check if the connection of steering column assembly and steering gear assembly is proper (there is not looseness of mounting bolts, damage of rods, boots or sealants, and leakage of grease, etc.). • Check if the wheel alignment is adjusted properly. • Check if there is any damage or modification to suspension or body resulting in increased weight or altered ground clearance. • Check if installation conditions of each link and suspension are proper. • Check if the battery voltage is proper. • Check connection conditions of each connector are proper. • Check that NISSAN genuine power steering fluid (E-PSF) is used. If power steering fluid other than genuine fluid is used, steering may become extremely hard. • You may hear a high pitch noise from the front of the vehicle when the steering wheel is operated, especially at low speed such as a parking lot. However this is not a malfunction. Steer at low speed condition makes higher load for steering rack, so pump works higher rotation to provide more hydraulic flow to create more power assistance for lighter steering effort. This pump rotation is electrically controlled based on rotation map in ECU. • Before connecting or disconnecting the power steering control module harness connector, turn ignition switch “OFF” and disconnect battery ground cable. Because battery voltage is applied to power steering control module even if ignition switch is turned “OFF”.

CONDITIONS FOR HYDRAULIC PUMP ELECTRIC POWER STEERING WARNING LAMP ON • When the hydraulic pump electric power steering system is operating and steering assist force is being generated, the hydraulic pump electric power steering warning lamp is OFF. • When the hydraulic pump electric power steering system is stopped by the fail-safe or protective function and steering assist force is not being generated, the hydraulic pump electric power steering warning lamp turns ON to inform the driver that the system is in the manual steering state. NOTE: When the hydraulic pump electric power steering system turns ON according to the protection system, the cause is internal high temperature state of the hydraulic pump electric power steering system. By stopping the engine, internal temperature of the system decreases. After starting the engine, the system returns to the normal state and the hydraulic pump electric power steering system warning lamp turns OFF. (The system is not malfunctioning.) For information about the protective function, refer to STC-9, "HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM : Protection Function". • When the ignition switch is turned ON, this lamp turns ON for lamp check (system check).

B HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM : Protection Function INFOID:0000000007492028 • When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low speed driving, the function of the hydraulic pump electric power steering system becomes limited to prevent the system from overheating. If the steering wheel is operated further more, the hydraulic pump electric power steering system stops and the hydraulic pump electric power steering system warning lamp may be turned ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction. When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the temperature of the hydraulic pump electric power steering system decreases and the steering operation returns to normal after restarting the engine. • Then, the hydraulic pump electric power steering system warning lamp turns OFF. If the system is OFF under the protection state, the hydraulic pump electric power steering system warning lamp turns ON to warn that the system is in the manual steering state. (This is not a system malfunction.) In addition, the following DTC remains to distinguish from malfunction.

This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. C D E F G H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

BELT PRE-TENSIONER" B INFOID:0000000007492989 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front D air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: WT Always observe the following items for preventing accidental activation. • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by F an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag G Module, see “SRS AIR BAG”. • Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. H PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation. • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Service Notice and Precautions for TPMS WT-3 J K INFOID:0000000007492990 • Low tire pressure warning lamp blinks for 1min, then turns ON when occurring any malfunction except low tire pressure. Erase the self-diagnosis memories for Tire Pressure Monitoring System (TPMS), or register the ID to turn low tire pressure warning lamp OFF. For ID registration, refer to WT-20, "Work Procedure". • ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to WT-20, "Work Procedure". • For easy fill tire alert function, refer to the following. - When inflating the tires, park the vehicle in the safe area and ensure the safety of the working area. - Read and understand the easy fill tire alert function prior to use. - Inflate the tires one at a time. - If there is no response for approximately 15 seconds or more after inflating the tires, cancel the use of the easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again. The air filler pressure may be weak or out of service area. - Despite the high-precision TPMS pressure sensor, an indicated value may differ from that of the pressure gauge. - Air pressure is measured rather high due to the rise in tire air temperature after driving. - If TPMS is malfunctioning, the easy fill tire alert is unusable. • Replace grommet seal, valve core and valve cap of tire pressure sensor in TPMS, when replacing each tire by reaching the wear limit. Refer to WT-45, "Exploded View". • Because the tire pressure sensor conforms to North America radio law, the following items must be observed. - The sensor may be used only in North America. - It may not be used in any method other than the specified method. - It must not be disassembled or modified.
