The purpose of this brochure is to acquaint you with the technical highlights of this new vehicle in advance of its market launch. This brochure is intended to provide information for people employed in service or maintenance/repair as well as for aftersales staff. It is assumed here that the reader is already familiar with the Mercedes-Benz model series currently on the market. In terms of the contents, the emphasis in this Introduction into Service Manual is on presenting new and modified components and systems. This Introduction into Service Manual is not intended as an aid for repairs or for the diagnosis of technical problems. For such needs, more extensive information is available in the Workshop Information System (WIS) and via Xentry Diagnostics. WIS is updated continuously. Therefore, the information available there reflects the latest technical status of our vehicles. The Introduction into Service Manual presents initial information relating to the coupe in model series 218 and, as such, is not stored in WIS. The contents of this brochure are not updated. No provision is made for supplements. We will publicize modifications and new features in the relevant WIS documents. The information presented in this Introduction into Service Manual may therefore differ from the more up-to-date information found in WIS. All information relating to technical data, equipment and options is valid as of the copy deadline in September 2010 and may therefore differ from the current production configuration.

Status: 09 / 2010 – Vehicle concept Innovations In January 2011, the CLS-Class of model series 219 will be superseded by the newly developed coupe of model series 218. With the new CLS-Class, the customer will obtain a coupe which sets the standard in terms of its new design, reliability, comfort, efficiency and safety. • Full-LED headlamps incl. Intelligent Light System (ILS) and Night-View function as special equipment (SA) • Electromechanical steering (EPS) Dimensional concept The dimensional concept of the new CLS-Class is derived from that of the predecessor model series 219 and is characterized by more space in the interior and a restyled body. The vehicle length has increased by 30 mm. This allowed the wheelbase to be extended by 20 mm. With the new CLS-Class, Mercedes-Benz is underlining its aspiration to lead the market in the segment of 4-door coupes, particularly in the areas of design, active and passive safety as well as environmental technology. Overview Brief description Innovative driving assistance systems Alongside ATTENTION ASSIST (attention assistance system) which is included as standard, the following assistance systems are available as special equipment: • Adaptive Highbeam Assist • Speed Limit Assist • Automatic lane recognition or Active Lane Keeping Assist • Blind Spot Assist or Active Blind Spot Assist • Active Parking Assist incl. PARKTRONIC • Night View Assist Plus • Reversing camera • DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake Environmental compatibility Crucial factors in environmental compatibility are not only fuel economy and emissions while driving, but also the environmental burden and consumption of resources from manufacture through vehicle use to recycling and disposal. The new CLS-Coupe sedan is thus certified on the basis of the strict international ISO standard 14062 "Design for Environment" at market launch. This environmental certification confirms the holistic approach in aspects of environmental protection: i Note Further details on the electrical systems of model series 218 (e.g. function descriptions and the locations of electrical components) are available in the Workshop Information System (WIS) under "Basic knowledge/functions" (GF). • • • • • Designed with recycling in mind Use of high-quality secondary raw materials Use of biomaterials Avoidance of potentially hazardous substances Recycling concept Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service.

The underfloor is equipped with a continuous engine compartment and main floor panel as well as an aerodynamically designed spare wheel well in order to reduce aerodynamic drag. 2 Fuel pump Regulation of the fuel pump significantly reduces its consumption of electrical power. The power requirements of the fuel pump depend on the amount of fuel currently required. 3 Rear axle The extended rear axle ratio lowers the engine speed and thus fuel consumption. 10 5 Outside mirror housing The new freestanding outside mirrors have been optimized aerodynamically. 6 Tires (standard equipment) The use of silicates in the tires means that the tire temperature quickly increases in critical situations to improve the grip to the level of a standard tire. This means that all properties relevant to usage can be retained while improving the rolling resistance at the same time. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – 7 Radiator shutters 9 Energy management The flow of cooling air through the cooling module and engine compartment can be regulated by opening the radiator shutters. Closing the radiator shutters at low outside temperatures prevents the engine compartment from cooling down. This means that more heat output is available for the passenger compartment. In addition, the reduced volume of cooling air reduces the aerodynamic drag of the vehicle. When the battery charge level is sufficiently high, alternator operation is scaled back to supply the base load requirements of the vehicle. The vehicle is then only supplied with power by the alternator, the battery is charged by occasional "coupling" of the alternator in deceleration mode. 8 ECO start/stop function With the ECO start/stop function, the engine can be shut off when the vehicle is at a standstill depending on vehicle and driver-related conditions in order to reduce the fuel consumption in the driving cycle. Overview Brief description 10 Engine optimizations The engines used combine high power with low fuel consumption. On the 4-cylinder diesel engine OM 651, this is achieved through dual-stage turbocharging. The new gasoline engines M 276, M 278 and M 157 AMG make use of downsizing, modularization and technological developments across the board. The engines feature newly developed piezo fuel injectors, multi-spark ignition (6-cylinder gasoline engine with stratified operation M 276 DES), turbocharging (M 278 and M 157 AMG) as well as a new oil and coolant thermal management system. Summary When combined, all of these measures result in significantly lower fuel consumption.

Status: 09 / 2010 – Front view In its second generation, the new CLS-Class once again embodies the unique four-door coupe concept of Mercedes-Benz. The front is characterized by the distinctive coupe grille. The two slats of the grille, combined with the large, centrally positioned Mercedes star, indicate that this vehicle belongs to the Mercedes-Benz family of coupes. The "soft nose" front end is a new feature with its distinct tapering and large air intakes. Incorporating a plastic bumper and aluminum engine hood, the soft nose meets the relevant legal requirements in the area of pedestrian protection. The front fenders of the CLS 63 AMG are 8 mm wider, underlining the sporty character of the vehicle. As a result, the track width of the vehicle is different but the overall vehicle width remains at 1881 mm. Overall vehicle Exterior The swept headlamps with their wide, outwardpointing design form the basis of the side contour. Alongside the standard bi-xenon headlamps with round daytime running lights (CLS 63 AMG with LED daytime running lights) in the bumper, full-LED headlamps with LED daytime running light strips are available for the first time as special equipment (SA).

Status: 09 / 2010 – 21 Overall vehicle Exterior Rear view The design of the rear end is distinctive with an emphasis on its width. This effect is underlined by the markedly tapered C-pillars in combination with the deeply contoured arching over the rear wheel wells. Extending into the side wall, the full-LED rear lamps are a standard feature of the vehicle. The rear fog lamp has been relocated centrally to the lower area of the bumper. This has allowed the taillights and turn signal indicators to be arranged in a ring shape around the backup lamps. The brake light consists of the same visual pattern as the taillight. The brake light function is realized by increasing the brightness of the LEDs.

Status: 09 / 2010 – 47 Drive Fuel system Diesel engines On diesel engines OM 651 and OM 642, fuel is supplied via the low-pressure fuel circuit and highpressure fuel circuit subsystems. The fuel reaches the high-pressure pump from the tank via the low-pressure fuel circuit. When actuated, the fuel pump draws the fuel out of the fuel feed module and pumps it through the fuel filter to the highpressure pump. Depending on the fuel requirements, the fuel pressure is regulated to approx. 4.0 bar. In addition, the quantity control valve regulates the flow of fuel to the high-pressure pump in order to keep its temperature low. In the high-pressure fuel circuit, the fuel is pumped into the left-hand rail and from there simultaneously into the right-hand rail by the high-pressure pump depending on the accelerator pedal signal, the engine speed and the fuel temperature. The fuel reaches the fuel injectors from the respective rail via the high-pressure lines. Based on a performance map, the CDI control unit calculates the cylinder-selective injection quantity for the respective operating condition. This is dependent on the fuel pressure in the rails and the actuation duration of the fuel injectors. Fuel preheating The fuel preheating system heating element is integrated in the fuel main filter in order to ensure flowability of the fuel at low outside temperatures. Excepted from this are vehicles with (code U41) Fuel/ water separator and lubrication package, with (code U42) BlueTEC diesel emission control (SCR) and with (code 494) USA version. These vehicles feature a fuel filter condensation sensor with heating element for water level monitoring. The heating element is energized by the glow output stage and warms up the fuel in the fuel filter. The current condensation level is transmitted to the CDI control unit via the fuel filter condensation sensor. As of a condensation level of approx. 100 ml, the CDI control unit transmits a message via chassis CAN to the instrument cluster, which displays this on the multifunction display as a warning message. The fuel pressure in the rails is controlled by the pressure regulating valve and the quantity control valve. The fuel pressure actually present in the rails is recorded by the rail pressure sensor, continuously forwarded onto the CDI control unit and limited to max. 2000 bar by the pressure regulating valve. i Note Leak fuel and unneeded fuel is returned to the fuel tank via the return line. 48 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Drive Fuel system Gasoline engines On engines M 276, M 278 and M 157, fuel supply is also carried out by the low-pressure fuel circuit and high-pressure fuel circuit subsystems. The fuel reaches the high-pressure pump from the tank via the low-pressure fuel circuit. When actuated, the fuel pump draws the fuel from the fuel feed module and pumps it through the fuel filter to the high-pressure pump (M 276) or to the two highpressure pumps (M 278 and M 157). Depending on the fuel requirement, the fuel pressure is varied from approx. 4.5 to 6.7 bar. In the filter feed line there is a check valve which prevents the fuel pressure from dissipating when the fuel pump is shut off. The fuel from the fuel tank flows from the low-pressure fuel distributor to the high-pressure pump. This increases the fuel pressure to up to 200 bar (depending on the operating state) and directs it through the high-pressure line and the rails to the fuel injectors. In the high-pressure fuel circuit, the high fuel pressure necessary for jet-guided direct injection is generated, regulated and stored in the rails. The fuel injectors in each cylinder bank are supplied with fuel directly from the corresponding rail. There are no return lines on the rails. Each high-pressure pump has a quantity control valve which regulates the fuel quantity supplied to the pump element according to the specified fuel pressure. The fuel pressure and temperature sensor registers the current fuel high pressure (rail pressure) and the fuel temperature in the left rail on the M 276 or in the right rail on the M 278 and M 157. The rail pressure is regulated by the ME-SFI [ME] (motor electronics) control unit, which actuates the quantity control valve with a PWM signal until the specified pressure is obtained in the rail.

Status: 09 / 2010 – Drive Fuel system Fuel tank As in the predecessor model series, the fuel tank in model series 218 is located in front of the rear axle under the rear bench seat in order to provide the largest possible opening between the trunk and the passenger compartment when the rear seat backrest is folded down. The blown fuel tank is a new development and is made of high-density polyethylene (HDPE). The complex shape of the thermoplastic fuel tank has a multiplelayer wall construction of six layers with a block layer to prevent hydrocarbon penetration. In all models, two service holes on the top of the tank facilitate removal of the pump and the filter unit with pressure sensor. The expansion volume is inside the fuel tank. The fuel tank fill level is measured by a dedicated float-and-lever sensor in each chamber. Each float-and-lever sensor has its own electrical connector plug. Gasoline engine purging with (code 494) USA version The activated charcoal filter shutoff valve is actuated by the ME-SFI [ME] control unit to control the ventilation connections. This allows the legally prescribed leak test of the purge system to be performed. Via the OBD pressure sensor (On-Board Diagnosis = OBD), the internal pressure of the fuel tank is recorded for the leak test. This is located in the center above the tunnel on the fuel tank.

The consumption-reducing measures include a dual turbine torsional damper with rpm-adaptive centrifugal pendulum (not on CLS 350), which allows for extreme reduction of slip at the torque converter lockup clutch, combined with greater mechanical damping insulation even at very low loads and engine speeds, including during shift operations. Furthermore, drag has been reduced by a new bearing on the oil pump, improved Torlon rings on the input and output shafts as well as a new automatic transmission fluid (FE-ATF) with reduced viscosity. The color of the new fluid has been changed from red to blue because it may not be used in older model transmissions. The notes in service information SI00.40-P-0014A in WIS on usage of the new transmission fluid must be observed. The oil change intervals have been extended because the transmission fluid is subjected to less energy due to the minimization of drag. For more information, see the corresponding documents in WIS.

It is installed in the transmission bell housing behind the start-up clutch and is driven by the drive spigots of the start-up clutch. Oil supply with combustion engine OFF (stop/ start function) When the combustion engine is shut off in ECO start/stop mode, the oil supply by the primary pump is interrupted. The electric transmission fluid pump (auxiliary pump) takes over the oil supply to the shift elements in position.

The steering gear is designed as a direct steering system. The steering ratio is noticeably more direct through the steering angle, which significantly improves vehicle handling and responsiveness. On the CLS 63 AMG, the steering has an even more direct set-up with a continuous ratio, providing a more sporty response particularly around the center position. The electric power steering consists of the rack-andpinion steering, torque sensor, actuator motor and electric power steering control unit. The electric power steering is maintenance free. The electric power steering provides stepless, speeddependent regulation of steering force assistance. The advantages compared to hydraulic power steering are: • Improved steering feel • Steering force assistance also available during stop/start operation • No power steering fluid required • Compact design • Speed-dependent power assistance • Diagnosis capability The electric power steering consists of the following subfunctions: • • • • Steering force assistance Steering assistance Emergency operation Instrument cluster display Steering force assistance The electric power steering control unit determines the following information to calculate the steering force assistance required: The control unit uses this information to calculate the steering force assistance to be applied from the stored characteristic map and activates the electric power steering actuator motor accordingly. The steering force assistance is transferred from the actuator motor to the rack-and-pinion steering via a belt drive and recirculating ball mechanism. Steering assistance The steering assistance function is intended to help the driver achieve the optimal steering characteristics in critical situations. Assistance is provided when braking on one-sided road surfaces. Steering assistance is provided via the electric power steering control unit and Electronic Stability Program control unit (except (code 233) DISTRONIC PLUS) or via the Premium Electronic Stability Program control unit (with (code 233) DISTRONIC PLUS). Emergency operation When the electric power steering is switched on, the electric power steering control unit performs a selftest. If a fault is detected the servo assistance is not activated. During driving operation, the electric power steering control unit checks the signals of the torque sensor and the current sensor in the actuator motor. If the signals are outside the defined values, the electric power steering is switched off. In both cases, the vehicle can be steered with increased force of the hand. Instrument cluster display The electric power steering control unit control unit transmits the request for a warning message via chassis CAN to the instrument cluster. On the multifunction display, the warning message "Power steering defective! Service required!" is displayed. • Current steering torque from torque sensor • Current wheel speeds via rpm sensors on front and rear axle • Steering angle and steering speed from steering angle sensor 56 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service.

An electrically adjustable version with easy-entry function is offered as special equipment in the memory package. The torsional damper (flexible coupling), which was previously installed in the engine compartment, has been relocated to the upper section of the steering column and thus the interior compartment. This results in better decoupling of vibrations for the steering wheel. Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service. Status: 09 / 2010 – 57 Chassis Axles Front axle Rear axle For the best possible vehicle dynamics and ease of installation, the front axle and steering gear are preinstalled on a frame-type integral support together with the engine and transmission. The remarkably rigid and low-weight frame-type integral support is made of high-strength steel and is bolted directly onto the longitudinal members of the body. The principle of the lightweight independent multilink rear suspension suspended from a subframe was selected because of its wheel control properties. The axle components have been modified in the interests of greater ride comfort and vehicle dynamics. For the front suspension, a further developed version of the three-link front axle has been chosen, as on the E-Class (W 212). Its major feature consists of two separate control arms (strut rod and cross strut) in the lower steering plane. These are steeper than on the W 212 and raise the roll center to 90 mm. This provides greater roll support with the same torsion bar diameter and greater negative camber on the outer wheel when cornering. The stabilizer bar is connected to the suspension strut via a link rod. The strut rod, which points to the front on an angle, is a weight-optimized, forged aluminum component. The cross strut aligned in the transverse direction consists of forged steel. Lightweight design techniques were used consistently for the new developments. The panel thicknesses of the subframe have been adjusted to reduce the unsprung masses. In addition, almost all wheel control parts are made of aluminum. Another comfort-related feature is the use of an additional support for the front subframe mounting on the body, which considerably increases the rigidity to introduced forces. The lighter-weight rear axle carrier made of highstrength steel has been adapted to the new dimensional concept. The box-shaped profile of the two side parts and the rear cross brace are formed from two half shells welded together. The front cross brace is a single shell. The third link is the tie rod, which forms part of the new rack-and-pinion steering. The arrangement and design of the wheel control parts, and in particular the splitting of the lower wishbone control arm into two individual links, provide favorable characteristics in terms of axle kinematics. i Note If the driver's body impacts with the steering column, the steering column can move forward by up to 100 mm under a predefined force in order to reduce the loads on the driver. For this purpose the entire substructure of the steering column tube is suspended on a slide that runs in a mounting console rigidly mounted in the body. In the event of a severe frontal impact the lower part of the steering column can telescope and the integral corrugated tube can deform. 58 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Suspension systems AMG On the 4 and 6-cylinder models, the new CLSCoupe is equipped with conventional steel suspension with selective damping system as standard equipment and with AIRMATIC air suspension with continuous adjustment damping (code 489) as special equipment. AIRMATIC forms part of the standard equipment for the 8-cylinder models. The CLS 63 AMG is equipped with steel/air suspension as standard. This consists of a combination of steel suspension on the front axle and air suspension on the rear axle with continuous damper adjustment. The damping is adjusted wheel-bywheel in accordance with the road surface condition and driving style. Damping stage "C" is always active after the ignition is switched on. Chassis Suspension i Note If a vehicle with AIRMATIC (code 489) is parked with transmission mode "E" selected and locked within 60 s, the vehicle lowers by 15 mm.

However, as part of the component optimization process in terms of lightweight construction, the front floating/fixed caliper with brake caliper housing features an aluminum or aluminum composite design. The rear floating caliper with brake caliper housing is made of aluminum. AMG The CLS 63 AMG features composite brake disks with silver-colored brake calipers as standard. The brake calipers of the Performance Package are red (not compulsory). As special equipment, ceramic brake disks with bronze-colored brake calipers are available. Adaptive Brake assists the driver when dangerous situations suddenly occur. It is installed as the ABR basic system (except (code 233) DISTRONIC PLUS) and ABR premium system (with (code 233) DISTRONIC PLUS). The familiar system has been adapted to the new model series and consists of the following subfunctions: • • • • • • • • • • • • Electronic Stability Program (ESP) Electronic brake force distribution (EBD) Antilock Brake System (ABS) Acceleration skid control (ASR) Electronic traction system (ETS) Brake Assist (BAS) BAS PLUS, with (code 233) DISTRONIC PLUS Hill Start Assist Dry braking Precharging HOLD function ASR and ESP passive mode (except CLS 63 AMG) • ASR and ESP-ON, ESP-SPORT and ESP-OFF (only CLS 63 AMG) • System fault display • Exhaust test, roller dynamometer mode P42.10-2843-00 Ceramic brake on CLS 63 AMG (front axle) 60 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service.

Status: 09 / 2010 – Introduction The ever increasing demands on the on-board electronic system in the fields of vehicle safety, comfort, communications and diagnosis require wider and wider networking of the existing systems in order to allow the necessary information to be exchanged. To provide complete vehicle networking, a number of control units also function as gateways, i.e. data from the connected bus systems are relayed by these control units. The following data bus systems are used to exchange the necessary information: • Controller Area Network (CAN) • Media Oriented System Transport (MOST) The network architecture of the CLS-Coupe largely matches that of the E-Class (model series 212). Interior CAN (CAN B) Networking Overall network The interior CAN is responsible for data transfer in the vehicle interior. Transfer rate 125 kbit/s. Drivetrain CAN (CAN C) The drivetrain CAN is responsible for data transfer by the drive systems. Transfer rate 500 kbit/s. Diagnostic CAN (CAN D) The data link connector can be used to connect an external tester (e.g. Xentry Diagnostics) to the diagnostic CAN. Transfer rate 500 kbit/s. Chassis CAN (CAN E) The chassis CAN is responsible for data transfer by the chassis and suspension systems. Transfer rate 500 kbit/s. CAN The CAN is an electrical bus system that transmits data over two lines. Each connected control unit can send or receive data (bidirectional bus). A data protocol defines the individual data blocks and specifies which data can be received or transmitted by a control unit. Any errors detected are saved and stored in the fault memory. The following CAN buses are involved in the overall network: Telematics CAN (CAN A) The telematics CAN is responsible for data transfer by the telecommunications systems. Transfer rate 125 kbit/s. Front end CAN (CAN G) The front end CAN is responsible for data transfer by the front light systems in vehicles with xenon headlamps. Transfer rate 500 kbit/s. Vehicle dynamics CAN (CAN H) The vehicle dynamics CAN is responsible for data transfer of the vehicle dynamic data, e.g. the turn rate or longitudinal acceleration. Transfer rate 500 kbit/s. Drivetrain sensor CAN (CAN I) The drivetrain sensor CAN is responsible for data transfer at the exhaust system. Transfer rate 500 kbit/s.

Status: 09 / 2010 – 69 Networking Overall network MOST Fuses MOST is an optical networking system. Data are transmitted via fiber optic cables between the connected information, navigation and communications components. Transfer rate 22 MBit/s. Mini and standard flat pin fuses are used. They are located in the following positions on the vehicle so that they are accessible to the customer: Front SAM control unit with fuse and relay module with central gateway function One innovation is the integration of the central gateway with the front SAM control unit with fuse and relay module in a single housing. Both control units feature separate microprocessors, each with a dedicated CAN interface. Wiring harnesses The wiring harnesses for the interior compartment, cockpit and engine compartment are designed customer-specifically. The wiring harness variants result from the basic standard equipment, the engine type, special equipment and national versions. • In the front fuse and relay box (SRB) in the engine compartment • In the rear fuse and relay box (SRB) in the trunk • In the cockpit fuse box (equipment-dependent) Mega, midi and strip fuses are located in the prefuse box and cannot be replaced. The fuse box can only be replaced in its entirety. The prefuse box contains a pyrofuse that isolates the starter and alternator line from the battery in the event of a crash. On vehicles with ECO start/stop function, the starter wiring harness is isolated by a pyrofuse on the battery terminal in the event of a crash. The wiring harnesses in the interior compartment are routed through the frame floor system in an H-shape and are protected by cable ducts in special areas. 70 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service.

Status: 09 / 2010 – 71 Networking Energy management Energy management The energy management system manages the supply and consumption of electrical energy. The aim is to ensure that the engine can be started and that all electrical consumers receive a reliable power supply. This is achieved through the major assembly coordinator and on-board electrical system management subsystems. Major assembly coordinator The major assembly coordinator is integrated in the CDI control unit (with diesel engine) or in the MESFI [ME] control unit (with gasoline engine) and forms the interface of the on-board electrical system management to the alternator. The CDI or MESFI [ME] control unit communicates with the alternator via the drive train LIN (LIN C1). The major assembly coordinator regulates the power output of the alternator in accordance with the instructions of the on-board electrical system management, taking the engine load into account. The following components record and evaluate the variables required for this: • Rear SAM control unit • CDI control unit or ME-SFI [ME] control unit • Alternator On-board electrical system management The on-board electrical system management monitors the on-board electrical system load and actively intervenes in the energy balance in order to ensure that the engine can be started and that all electrical consumers receive a reliable power supply. The rear SAM control unit operates as the master control unit for energy management. The energy management system comprises the following subsystems: • Driving operation energy management • Engine standstill energy management • Engine start/stop function energy management (with (code B03) ECO start/stop function) Driving operation energy management The driving operation energy management subsystem ensures that the on-board electrical system remains stable and guarantees an equalized charge balance of the on-board electrical system battery. Due to the rpm and temperature-dependent power output of the alternator with simultaneous operation of many consumers, load situations may arise which have to be buffered by the on-board electrical system battery. If this situation is ongoing or if the on-board electrical system battery has a low charging capability, this can result in a negative charge balance. This can mean that the vehicle is not able to be started. The driving operation energy management subsystem increases the power output of the alternator if the on-board electrical system is overloaded on an ongoing basis. Alternatively, the power consumption of comfort-related consumers can be scaled back to achieve an equalized charge balance of the on-board electrical system battery. Energy management is mainly performed by the following components: • • • • • Battery sensor On-board electrical system battery Alternator CDI control unit or ME-SFI [ME] control unit Rear SAM control unit with fuse and relay module • ECO start/stop function additional battery (with (code B03) ECO start/stop function) 72 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – The driving operation energy management subsystem is divided into the following subfunctions: • Voltage control - Determine battery charge level - Charge on-board electrical system battery - Alternator control • Dynamic idle control • Consumer reduction Engine standstill energy management The engine standstill energy management subsystem ensures that the on-board electrical system remains stable and that the vehicle can be started after the engine has been switched off. This functionality is integrated in the rear SAM control unit and allows the on-board electrical system battery to remain idle for long periods. The engine standstill energy management subsystem consists of the following subfunctions: • Consumer shutoff • No-load current management • External charging/jump starting No-load current management The no-load current management function ensures that the vehicle can be started. This function is integrated in the rear SAM control unit and allows the vehicle to remain idle for extended periods without the on-board electrical system battery discharging completely. Networking Energy management For this purpose, consumers on circuit 30g are disconnected from the power supply through actuation of the no-load current shutoff relay. The no-load current management function allows increased energy consumption for a certain period of time after the engine is shut off (max. t = 75 min). This is desirable, for example, when the radio is left switched on while the car is being washed. External charging/jump starting If the on-board electrical system battery does not have sufficient capacity to start the engine, it must be charged or a jump start must be carried out. Consumer shutoff Consumer shutoff is activated when the on-board electrical system voltage drops below U = 11.8 V or when the engine is off (circuit 61 OFF) and circuit 15 ON is switched to circuit 15R ON In addition to consumer reduction from the driving operation energy management subsystem, a consumer is shut off every t = 5 s. When the on-board electrical system voltage stabilizes at a value above U = 11.8 V, the consumer shutoff function is nevertheless not canceled. The consumers which have been shut off are only put back into operation after the system is reset by turning the transmitter key to circuit 15C. i Note During the jump starting process or during testing work in the workshop, one of the front doors must be opened. The alternator management system thus switches to jump starting or workshop mode and the alternator voltage is raised to U = 13.9 V. i Note The on-board electrical system battery may only be charged with direct current.

The additional battery is connected by actuating the ECO start/ stop function additional battery electronic relay. The following function requirements must be met: • Engine running and at operating temperature • Engine hood closed • Speed of v = 15 km/h exceeded once during forward travel • System diagnosis complete • Outside temperature T = -10 to 40 °C • Battery temperature T = 0 to 60 °C • Set air conditioning temperature reached The CDI control unit (with diesel engine) or ME-SFI [ME] control unit (with gasoline engine) operates as the master control unit, recording and evaluating all variables. The use of the ECO start/stop function additional battery with a capacity of 12 Ah prevents a voltage dip during engine starting. The additional battery thus takes over power supply to the active consumers, while the on-board electrical system battery is disconnected from the on-board electrical system during engine starting. This means that active comfort functions are not switched off. After the engine is cold started, the CDI or ME-SFI [ME] control unit performs a system diagnosis and evaluates the operational capability of the start/ stop function. In addition, the front SAM control unit checks the operation of the components for decoupling the on-board electrical system battery and connecting the additional battery. 74 The engine start/stop function is made up of the following subfunctions: • • • • • Engine stop Engine start Forced engine start Determine status of additional battery Charge additional battery Engine stop The CDI or ME-SFI [ME] control unit checks the information provided by the rear SAM control unit about the condition of the on-board electrical system, the on-board electrical system battery, the additional battery and the requirements of loadintensive consumers (e.g. air conditioning). After evaluation of all of the relevant data, the engine stop is enabled and the engine is shut off. After an engine stop, a maximum of three engine starts without exceeding the speed threshold of v = 8 km/h in forward travel are permitted. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Forced engine start i Note When the blower for automatic air conditioning is active, the blower output is reduced. At warm ambient temperatures, the system switches to air recirculation mode depending on the specified temperature setting. Engine start The CDI or ME-SFI [ME] control unit evaluates all of the relevant variables and issues the start enable signal (warm start signal). The front SAM control unit reads in this signal and actuates the ECO start/ stop function diode in the front fuse box and the ECO start/stop function additional battery relay on the additional battery. The additional battery is connected to the on-board electrical system. Then, the ECO start/stop function diode disconnects the on-board electrical system battery from the on-board electrical system for the duration of the starting procedure. The energy demands of the on-board electrical system are then met by the additional battery and the onboard electrical system battery supplies the energy required to start the engine. In order to ensure the stability of the on-board electrical system even with the engine at a standstill, the CDI or ME-SFI [ME] control unit can initiate a forced engine start. Networking Energy management A forced engine start is carried out if the stability of the on-board electrical system can no longer be guaranteed due to the requirements of load-intensive consumers. Load-intensive consumers can be requested by the following systems: • Supplemental restraint systems • PRE-SAFE® • Brake Assist System and distance control systems • Air conditioning • Steering If the on-board electrical system management detects possible instability of the on-board electrical system, the rear SAM control unit transmits an engine start request via the front SAM control unit to the CDI or ME-SFI [ME] control unit, which initiates the engine start. If the stability of the onboard electrical system is still not ensured after this, the engine is no longer shut off and the start/ stop function is shut off. As soon as the CDI or ME-SFI [ME] control unit detects an engine speed of n = 400 to 700 rpm, it terminates the starting procedure and transmits a corresponding signal to the front SAM control unit. The on-board electrical system battery is then reconnected to the on-board electrical system and it takes over the task of supplying the energy demands of the on-board electrical system. The additional battery is then disconnected from the onboard electrical system. Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service. Status: 09 / 2010 – 75 Networking Energy management Determine status of additional battery Charge additional battery After the engine is started, the front SAM control unit carries out the process of battery state recognition. This supplies information about the availability of electrical power from the additional battery. In addition, the voltage at the additional battery is tested after every engine start in start/ stop function mode. The charging strategy of the additional battery is determined by two requirements. On the one hand, the system must ensure that the additional battery is sufficiently charged and, on the other hand, the number of actuations of the additional battery relay and the resulting load on the additional battery must be minimized as far as possible. The ECO start/stop function additional battery relay is no longer actuated under the following conditions: When the open circuit voltage (U > 12.5 V) of the additional battery drops below the specified value, the output limitation of the alternator is deactivated so that the additional battery can be charged. • Additional battery is deep discharged • Internal short circuit • Short circuit in positive line of additional battery A corresponding fault message is shown on the multifunction display of the instrument cluster. If the voltage drop (U < 11 V) during engine starting is too high, the engine stop function is deactivated for t = 5 min in order to charge the additional battery. The ECO start/stop function is only activated if the output limitation of the alternator is not active and the on-board electrical system voltage is high enough (U > 13 V). It is shut off if the output limitation of the alternator is active or the on-board electrical system is under heavy load. i Note Battery state recognition can also be launched using the diagnostic tester. 76 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service.

The standard equipment includes bi-xenon headlamps with headlamp cleaning system (HCS). Aside from the new design of the headlamps, their functions have also been modified and expanded. The low beam and high beam light functions are carried out by a xenon bulb. The parking light, standing light and turn signal light functions are carried out by light-emitting diodes (LED). The daytime running light (bulb) is integrated in the bumper. The CLS 63 AMG has LED daytime running lights as standard.

All light functions are performed by LEDs. The LED daytime running lights are integrated in the bumper in a chrome-trimmed bar. To output the low beam and high beam light functions, the left LED driving lights actuation module and right LED driving lights actuation module are actuated by the front SAM control unit. The respective LED actuation module controls the short-range low beams, longrange low beams and the high beams. The LED signaling lights actuation module is actuated by the front SAM control unit for the parking light, standing light and turn signal light functions. The LED driving lights actuation module and LED signaling lights actuation module are located on the side or rear of the respective lamp unit. The long-range low beams are designed as spotlights and housed in a retaining frame. This allows the light cone to be swiveled both horizontally and vertically.

Status: 09 / 2010 – 79 Illumination Exterior lights Driving lights actuation Full-LED headlamps Low beams The low beam actuation request is made by turning the exterior lights switch to the "Manual driving lights" position. The electronic ignition lock control unit transmits the circuit status to the front SAM control unit. From there, the request is output to the LED driving lights actuation modules via a voltage signal. The LED actuation modules then actuate the low beams (short and long-range). High beams The high beam actuation request is made by pressing the combination switch forwards. i Note The long-range low beams are integrated in the low beam modules. The position of the shortrange low beams remains unchanged. i Note After replacing an LED on full-LED headlamps, synchronization has to be performed between the headlamp and headlamp control unit using XENTRY-Diagnostics. The steering column tube module control unit reads in the position of the combination switch directly and transmits this to the front SAM control unit. This sends the request "High beams ON" to the headlamp control units and outputs a voltage signal to the LED driving lights actuation modules. The headlamp control units actuate the headlamp range adjustment actuator motors. The low beam modules are raised to increase the range of the low beams. i Note The tourist function can be activated and deactivated via the instrument cluster. The LED high beam actuation modules also actuate the high beams. 80 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Intelligent Light System (ILS) Infrared lights The additional driving lights actuation functions of the Intelligent Light System enable optimal road surface illumination in various driving and weather conditions. Vehicles with full-LED headlamps can be supplemented with the special equipment option (code 610) Night View Assist Plus. LEDs are used to generate the infrared light. The infrared light emitted by the infrared lamps is not visible to the human eye. It therefore does not disturb or dazzle oncoming traffic. This is achieved by increasing the light output of individual light sources, selectively actuating additional light sources and through various actuators in the lamp units. This ensures that other road users are not inconvenienced or dazzled. Illumination Exterior lights The driving lights (low beams, high beams) remain active while the additional driving lights functions are actuated. The additional driving lights actuation functions comprise the following subfunctions: • Cornering lights • Dynamic curve illumination • Active light distribution with the subfunctions motorway lights, extended fog lights and adaptive high beams (with (code 608) Adaptive Highbeam Assist) a Danger! Extended exposure to infrared radiation can damage the eyes. This damage is not immediately noticeable. Observe the following instructions to ensure that this does not happen: • Avoid extended visual contact with activated infrared lamps. • When working on the front of the vehicle make sure that the infrared lamps are switched off.

Status: 09 / 2010 – The further developed passive safety system includes: Extended safety measures for pedestrians and cyclists: • Body structure with front and rear end constructions with high strain energy, and a high-strength passenger cell • A long deformation path due to short 4-cylinder and 6-cylinder engines mounted on a bolted frame-type integral support, which absorbs energy and deforms in the direction of the impact during a frontal collision • Multiple parallel load paths at the level of the longitudinal members for improved load distribution in the event of a partial head-on collision • Cockpit crossmember made out of extruded aluminum section between the A-pillars • Telescoping steering column • Doors with reinforcement profiles • Steering wheel with foamed rim • Airbag and seat belt restraint systems • PRE-SAFE® preventive occupant protection system • Soft nose front end as an extended protective measure for pedestrians and cyclists • Emergency illumination after an accident Reducing the severity of an accident is important particularly in the case of collisions with weaker road users such as pedestrians and cyclists, as these weaker road users have no crumple zones of their own. Safety Passive safety To supplement the active safety measures (the Brake Assist System, for instance), which prevent an accident from occurring or which can help to reduce its severity, the passive measures for pedestrian protection have been optimized even further in model series 218. For example, in order to reduce the stresses which occur in the event of an impact with the engine hood of the vehicle, the front end of the vehicle has a "soft nose" design. The upper area of the bumper and radiator grille are offset forwards accordingly and have a soft design. i Note The new procedure must be observed when removing the driver airbag.

Status: 09 / 2010 – General Multifunction camera Modern assistance systems effectively contribute towards accident avoidance. This was the result of analyses carried out by Mercedes-Benz based on representative data from accident research and the evaluation of real-life accidents. A multifunction camera is installed in model series 218 to control the various driving assistance systems. The multifunction camera is located below the inside rearview mirror on the windshield. On average, these technologies could help to prevent one fifth of all rear-end collisions involving passenger cars in Germany alone. The accident figures on freeways could be reduced by as much as 36%. The following systems are controlled: • Adaptive Highbeam Assist • Speed Limit Assist • Automatic lane recognition and Active Lane Keeping Assist Driving assistance systems Overview of systems The input variables and signals are read in by the multifunction camera via the chassis CAN. The integrated microprocessor evaluates the input variables and signals, and the relevant components are then actuated over the chassis CAN. The multifunction camera records images of the scene in front of the vehicle. The image recognition module recognizes the input signals of the camera, such as other road users, road signs and lane markings. The decision module compiles all the relevant data, such as references to other road users, their distance and angle, the vehicle's current environment and the current vehicle parameters. It then issues the appropriate requests, e.g. control of the headlamps, actuation of the instrument cluster or control of the vibration motor in the steering wheel. i Note All the driving assistance systems are merely aids for the driver in controlling the vehicle in certain difficult situations. They can never replace a properly relaxed and attentive driver. The driver bears sole responsibility at all times for the safety of his vehicle and its behavior. i Note If the multifunction camera is removed or the windshield is replaced, the camera must be calibrated using Xentry Diagnostics.

Status: 09 / 2010 – 89 Driving assistance systems Adaptive Highbeam Assist The adaptive high beams assistant with (code 608) is available as special equipment in combination with full-LED headlamps with Intelligent Light System. The headlamp range of the driving lights is adjusted to the distance of the nearest vehicle in front or nearest oncoming road user by actuating various actuators in the front lamp units. If no road users are detected, the adaptive high beams assistant automatically activates the high beams. The status indicator for the automatic high beams including optical headlamp range adjustment appears in the instrument cluster in the form of an indicator symbol on the multifunction display in addition to the familiar blue indicator lamp for the high beams. The multifunction camera on the windshield ensures that the headlamp range and the light cone are controlled so as to provide optimum illumination of the road according to the traffic situation (optical headlamp range adjustment). The transitions between the low beams and high beams are smoothly overlapped with no sudden light changes. The adaptive high beams assistant function is activated via the control menu level on the instrument cluster. When the exterior lights switch is in position "A", the multifunction camera has detected darkness and the vehicle speed is > 40 km/h, the adaptive high beams assistant can be switched on by pressing the combination switch to position "High beams".

Status: 09 / 2010 – The Speed Limit Assist function, which is available as special equipment with (code 513), uses the multifunction camera to record the speed limit for the section of road the vehicle is driving on as indicated by the road signs. The multifunction camera also records supplementary signs and derestriction signs. In addition, the verified attributes in the digital map of the navigation system are also evaluated. On the CLS-Class, the corresponding road signs are shown for the first time in color on the multifunction display and Audio/COMAND display. Speed Limit Assist is permanently active in the background. Image recognition The decision module processes the following relevant data: • The vehicle's surroundings registered by the multifunction camera • Speed and yaw rate • Attributes of the navigation system from the digital road map (e.g. type of road) When the data has been evaluated, the multifunction camera sends a corresponding request to control the display of the currently detected speed limit to the instrument cluster. It is operated via the menu "Speed Limit" on the instrument cluster. The multifunction camera even combines the speed limit information into a result if the information is contradictory. National legislation governing the design and installation of traffic signs is taken into account by the system. The image recognition module assigns degrees of probability to all the results and forwards these on to the integrated software modules. If one of the data sources (image recognition, vehicle data or navigation data) fails, Speed Limit Assist is temporarily unavailable. The function is deactivated if a control unit fails. Driving assistance systems Speed Limit Assist Display concept The display concept can be selected via the instrument cluster. A distinction is made between notification mode and permanent display: Notification mode In notification mode the detected speed limit is displayed in the form of a road sign for 5 s. The notification can be canceled within the display time. Notification mode can be switched on and off by the driver. The status is indicated by a symbol in the instrument cluster.

Status: 09 / 2010 – The attention assistance system is installed as standard on the new model series 218. It detects tiredness or increasing inattentiveness (e.g. during long monotonous freeway and highway driving) in the speed range of v = 80 to 180 km/h. Operator intervention at one of the following controls disables the detection of steering patterns: • All controls on the steering column tube module • Steering wheel buttons • All controls on the head unit If the attention assistance system detects signs which indicate that the driver is tired or increasingly inattentive, the driver is prompted to take a break through the output of visual and acoustic warning messages. The attention assistance system is switched on via the "Assist." menu in the "Attention Asst." menu level on the instrument cluster. A coffee cup symbol is displayed on the multifunction display. Driving assistance systems Attention assistance system During the driving states listed below, steering patterns are recorded which occur more frequently as the driver becomes increasingly tired or inattentive: • Monotonous journey (little longitudinal and lateral acceleration) • No noteworthy external stimulation (e.g. surface undulations or crosswind) Under the following conditions, operation of the attention assistance system is limited and warnings are not issued or issued with a delay: • On rough road surfaces (e.g. heavy service undulations, pot holes) • In strong crosswind • When driving in a sporty style with high cornering speeds or rapid acceleration • At speeds which are generally slower than 80 km/h or faster than 180 km/h • When the audio system is being operated, including telephony • During active driving situations e.g. changing lane or vehicle speed i Note The driving behavior is also analyzed when the attention assistance system is switched off. If the system is switched on while driving, then the entire trip from the beginning is thus taken into account. i Note The software used to analyze driving behavior is based on experience with testers whose different driving behavior was evaluated during the day and night. P54.32-8852-00 Representation in multifunction display (example) 1 Attention assistance system active 2 Warning message Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service. Status: 09 / 2010 – 93 Driving assistance systems Attention assistance system At the start of a trip, the algorithm determines a warning threshold for the individual driver. The sensitivity of this algorithm adjusts to the driving time and time of day. If the warning threshold is exceeded, the system prompts the driver to take a break with the message "Attention Assist: Pause!" on the multifunction display of the instrument cluster. In addition, an acoustic warning is output via the warning buzzer in the instrument cluster. The warning message can be acknowledged using the "OK" button on the left multifunction steering wheel button group. A new warning message can then only be issued after t > 15 min at the earliest. Special operating notes The following factors can affect correct operation of the system: No warning due to insufficient driving time in active speed range The attention assistance system analyses the development of driving behavior over time. The individual driving behavior is classified at the start of a trip. If the driving behavior changes on an ongoing basis, a warning is output. If the driving time in the active range (speed between 80 and 180 km/h) is too short, no warning is issued. No warning due to system limitations Even in the active range, the system is not able to evaluate driving behavior if certain circumstances occur e.g. frequent lane changes, twisty roads, frequent control operations, surface undulations or a dynamic driving style. If these factors occur continuously, the driving time in the active range is too short. 94 Individual factors related to driving situation or driving behavior The attention assistance system detects changes in driving behavior. However, these changes are not necessarily caused by tiredness or inattentiveness. They can also be caused by the peculiarities of a driver's individual driving style. Influence of time of day The attention assistance system responds more sensitively depending on the time of day in accordance with a curve which, for example, also reflects the "afternoon slump" (biorhythm). These findings have been determined based on a representative study, but may be different in individual cases. Influence of driving time The attention assistance system responds with increasing sensitivity as the driving time without a break increases. The weighting of the driving time is based on studies and corresponds to average tiredness patterns. Warning due to distraction or slight tiredness A driver's subjective feeling of tiredness and the objective evaluation criteria determined by the system may differ. However, the attention assistance system not only warns in the event of tiredness, but also if there is a significant change in driving style e.g. due to major distraction. In this case, a warning is issued due to increasing inattentiveness. Change in driving behavior due to other factors An increasingly slippery, narrow or rough road surface or deteriorating visibility can change driving behavior on an ongoing basis and influence the objective evaluation criteria determined by the system. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Automatic lane recognition with (code 476) The automatic lane recognition function detects when the vehicle unintentionally drives over lane markings and warns the driver in certain situations through vibrations at the steering wheel. Automatic lane recognition is activated in the "Assistance" menu on the instrument cluster. The status indicator on the instrument cluster lights up yellow when the system is switched on but not yet ready to issue warnings. As soon as the system is ready to issue warnings, the status indicator lights up green. Assistance is provided by the automatic lane recognition function in the speed range of 60 to 270 km/h. An additional prerequisite is a lane width of 2.5 to 4.6 m and a curve radius of r > 150 m. The automatic lane recognition function monitors the area in front of the vehicle using the multifunction camera. The system takes measurements of the lane markings on the road. From the recorded image sequences and the measurements of the road markings it calculates the position of the vehicle within the lane and the path of the lane itself. If there are multiple markings on the road, the innermost marking acts as the reference point. On the basis of this data, the multifunction camera can determine whether the driver is crossing a lane marking. When the automatic lane recognition function detects that one of the front wheels is touching or crossing a lane marking, it warns the driver that he or she is leaving the lane unintentionally. The warning is given by actuating a vibration motor in the steering wheel which provides the driver with a haptic warning by intermittently vibrating the steering wheel. Driving assistance systems Automatic lane recognition Suppression of the warning Under the following conditions, the system detects that the vehicle is crossing a lane marking but output of a warning message is suppressed: • When turn signaling • During driver activities, through evaluation of steering wheel movements, braking requests and accelerator pedal position • During sporty cornering (cutting corners) • During active control interventions by braking assistance systems P54.32-8346-77 Illustration of principle a The vehicle is located in the lane b The vehicle crosses an outer lane marking.

Brake system interventions are only ever carried out if: However, if the driver does not respond to the warning in the form of steering wheel vibrations, the video and radar sensor system control unit initiates targeted brake system interventions – if the relevant prerequisites are met – to move the vehicle back into the lane within the lane markings. • The system detects that a clearly visible, continuous line is driven over • The Electronic Stability Program has not been switched to passive mode • Run-flat mode (tires) is not active As with Lane Keeping Assist, warnings are issued at a speed of 60 to 270 km/h. However, brake system interventions are only made between 60 and 200 km/h. The lane width required for a warning is 2.5 to 4.6 m, for a brake system intervention a lane width of 2.6 to 4.4 m is required. Warnings are not issued for lane widths over 3.9 m where the vehicle is traveling at a speed of v < 100 km/h. i Note Brake interventions are only performed when the vehicle crosses over a continuous line (lane delimitation) at an angle of less than 3° and only if the lane is delimited by two lane markings. On the other hand, a warning is issued even when the vehicle crosses over a broken line. If the driver indicates to the system that he or she is "active" before or during the brake intervention, the brake intervention is suppressed or aborted. The brake intervention of the Active Lane Keeping Assist system is also suppressed or immediately aborted if the video and radar sensor system control unit detects activities from the following systems in the form of brake intervention requests: • • • • • Antilock Brake System (ABS) Acceleration skid control (ASR) Brake Assist (BAS) PRE-SAFE® Active Blind Spot Assist P54.71-2234-00 A Warning of driver when vehicle crosses lane marking B Brake system intervention if driver does not respond 96 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Additional function requirements for active brake system interventions • Two lane markings are present (lines, one of which may be broken) • Vehicle is detected leaving the lane • Driver warning has been issued • No driver activities are recognized Active brake system intervention In the video and radar sensor system control unit, the separately computed lane is compared with the images from the multifunction camera. If the comparison of the lanes matches sufficiently, the video and radar sensor system control unit generates a trusted lane. Driving assistance systems Active Lane Keeping Assist P54.32-8853-00 Status indication (shown for ECE) 1 Active Lane Keeping Assist active The detected driver activities are evaluated in order to enable a brake system intervention. Using this data and the trusted lane, the video and radar sensor system control unit uses a set algorithm to decide whether and with which intensity a lanecorrecting brake system intervention should be carried out. The request is transmitted via chassis CAN to the multifunction camera. After positive verification against the data of the multifunction camera, the video and radar sensor system control unit transmits a corresponding signal via vehicle dynamics CAN to the Electronic Stability Program control unit. This initiates the required wheel-selective brake interventions, which are implemented by the traction systems hydraulic unit. P54.32-8854-00 Status indication (shown for ECE) 2 Brake intervention, lane crossed on left If the video and radar sensor system control unit detects that the driver is actively cutting corners, driving over a lane marking at an angle of over 3° or detects lateral acceleration of g > 4 m/s2, the brake system intervention is suppressed.

Status: 09 / 2010 – 97 Driving assistance systems Blind Spot Assist Blind Spot Assist with (code 234) The Blind Spot Assist system serves to prevent accidents and supports the driver in safely carrying out a lane change. The Blind Spot Assist system monitors the blind spot, i.e. the area to the side of the vehicle behind the driver (see picture: Blind Spot Assist monitoring range). If there is a vehicle in the blind spot, the driver is visually notified that the intended lane change is not recommended. In the left and right outside mirrors, a readiness and warning indicator indicates that the system is active or if there is a vehicle in the blind spot. If the driver actuates the turn signal in the direction of a vehicle in the blind spot, an acoustic warning is also issued. The area which is not visible via the outside mirrors and inside rearview mirror is monitored by the left and right short-range radar sensors in the rear bumper. All relevant data are evaluated directly by the radar sensors, whereby the right radar sensor requests readiness and warning message output. Warnings are issued visually via the readiness and warning indicator in the left or right outside mirror and acoustically via the warning buzzer in the instrument cluster. Blind Spot Assist monitoring range 98 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – P54.70-2586-00 Active Blind Spot Assist with (code 237) Active Blind Spot Assist builds upon the functionality of Blind Spot Assist. Active Blind Spot Assist can additionally initiate course-correcting brake system interventions if the risk of a side collision is detected. Before and during a course-correcting brake system intervention, the area in front of and to the side of the vehicle is monitored additionally so that the course-correcting brake system intervention can be adjusted to the current traffic situation. For this purpose, the movements of all vehicles, particularly oncoming vehicles, and stationary obstacles in the vicinity of the vehicle are monitored and evaluated. The course-correcting brake system interventions take place on a wheel-selective basis and effect a change in course of the vehicle with the system. Noticeable course-correcting brake system interventions are indicated to the driver on the instrument cluster. In addition, the driver is warned visually and acoustically, as with the passive Blind Spot Assist system. The evaluation of all data for the Active Blind Spot Assist system is carried out by the video and radar sensor system control unit. If the video and radar sensor system control unit detects imminent danger of a side collision with a vehicle in the blind spot, a course-correcting brake system intervention is requested via the Premium Electronic Stability Program control unit. This selectively brakes individual wheels and guides the vehicle back onto a collision-free course. Driving assistance systems Blind Spot Assist The course-correcting brake system intervention is aborted if the driver steers against the direction of the course-correcting brake system intervention or the vehicle accelerates. Furthermore, the driving assistance systems and driving safety systems such as ABS, ASR, BAS, ESP and PRE-SAFE® brake have priority over the Active Blind Spot Assist system. If a risk of side collision is detected with vehicles that are in the blind spot, then an accident can thus be avoided or the consequences of an accident lessened. The area which cannot be observed via the outside mirrors and inside rearview mirror is monitored by the following sensors: • Left outer radar sensor, rear bumper • Right outer radar sensor, rear bumper The following sensors monitor the area in front: • Left inner short-range radar sensor, front bumper • Right inner short-range radar sensor, front bumper • Long range radar P54.70-2587-00 Active Blind Spot Assist monitoring range Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service.

When a vehicle speed of v > 30 km/h is reached, the yellow readiness indicators go out. If, at a vehicle speed of between v = 30 to 250 km/h, a vehicle is located in the radar sensor system sensing range, the driver is notified of it by the Blind Spot Assist warning lamp turning red in the outside mirror on the side of the vehicle on which the vehicle is located. Course-correcting brake system interventions are carried out up to a vehicle speed of v = 200 km/h. The risk of collision is displayed on the instrument cluster depending on the side.

Status: 09 / 2010 – The parking system uses the familiar PARKTRONIC distance warning system to record the distance between the vehicle and an obstacle (with (code 220) PARKTRONIC and (code 498) Japan version). On vehicles with Active Parking Assist (except (code 498) Japan version), parallel parking spaces are additionally measured and stored on both sides of the vehicle in the direction of travel while driving at speeds of v < 36 km/h. The vehicle can be parked semi-automatically at the request of the driver. In addition, the following subfunctions have been added to the system: • Parking space detection • Display of possible parking spaces • Semi-automatic parking The parking system distance sensors are actuated by the parking system control unit. These then output an ultrasound signal. The signal reflected by an obstacle is received and evaluated. The driver is warned about the respective distance between the vehicle and obstacle via the instrument panel parking system warning indicator and rear parking system warning indicator. The distance sensors are activated according to the direction of travel. On vehicles with Active Park Assist, the parking space detection area to the right and left of the vehicle is scanned up to a distance of s = 400 to 450 cm at speeds below 36 km/h. The data is stored as the vehicle continues to drive up to a distance of s = 15 m.

Status: 09 / 2010 – 101 Driving assistance systems Active Parking Assist Additional function requirements for parking space detection In addition to the PARKTRONIC function requirements, parking space detection only becomes active if there has been no intervention by the ABS or ESP system in the last t = 5 s. i Note At a speed range of 0 to 18 km/h, the parking system involves mixed operation of the PARKTRONIC function and Active Parking Assist function. As of a speed of 18 km/h, the parking system switches to the parking space detection function and remains active up to 36 km/h. Parking space detection The parking space detection function is used for locating suitable parallel parking spaces. The outer front distance sensors monitor the area to the left and right of the vehicle. The maximum range of the front distance sensors is between 400 and 450 cm depending on environmental influences. The data from the front distance sensors are read in and evaluated by the parking system control unit. The stored vehicle dimensions and the measurements of the recorded parking space are used to calculate whether the parking space is suitable for the vehicle. For a parking space to be detected by the parking system, it must be parallel to the direction of travel and at least 150 cm wider and 130 cm longer than the vehicle. i Note The parking system can detect a free space that is geometrically suitable for parking; it cannot tell whether this free space is actually a parking space. Display of parking spaces When the parking system is looking for a parking space, this is indicated by a "P" symbol on the instrument cluster. As soon as a suitable parking space is detected, a directional arrow appears next to this symbol to indicate on which side of the vehicle the parking space is located. Parking spaces are always looked for on both sides of the vehicle. However, only parking spaces on the passenger side are pointed out by default. To also allow parking spaces on the driver side to be displayed, the driver must actuate the turn signal in the appropriate direction. 102 P54.32-8952-00 Parking Guidance – Parking symbol on multifunction display b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service.

Status: 09 / 2010 – 103 Driving assistance systems Active Parking Assist The message "Activate parking assistant?" appears on the multifunction display of the instrument cluster. After the respective gear change is made, accelerator and brake pedal actuation has to be continued until the end position is reached. Alongside the warning message "Pay attention to surroundings", the option to activate the parking assistant appears in the lower section of the multifunction display. The steering column tube module control unit reads in confirmation from the multifunction steering wheel button group over the steering LIN (LIN E1) via the steering wheel electronics and transmits the corresponding request to the parking system control unit via chassis CAN. As soon as this end position is reached, the message "Parking assistance complete – Please take over" appears for a period of t = 5 s, accompanied by a warning tone. Semi-automatic parking Once the Park Assist function has been activated, the message "Please accelerate and brake independently" appears on the multifunction display. The driver can now take his or her hands off the steering wheel and actuate the accelerator and brake pedal. The Park Assist system is active up to a speed of 10 km/h. To implement the function, the parking system control unit transmits appropriate steering commands to the electric power steering (ES) control unit via the chassis CAN. For this purpose, it calculates the corresponding steering angle based on the size of the parking space detected and the data from the steering angle sensor. The ES control unit actuates the ES actuator motor of the ES electromechanical controller unit, which implements the corresponding steering movements via the steering gear. If the vehicle reaches a distance of s < 30 cm to the edge of the parking space (at front or rear), this is indicated by the first red LED lighting up on the parking system warning indicator. At the same time, the message "Please engage gear range D" or "Please engage gear range R" appears on the multifunction display. 104 The following circumstances result in deactivation of the system and thus cancellation of active parking assistance: • The permissible speed of v = 10 km/h is exceeded • The ES control unit detects active steering wheel intervention by the driver • A defect is detected in the electric power steering electromechanical controller unit • Controller Area Network (CAN) signals are faulty • The driver door and driver seat belt buckle are open simultaneously If the system is deactivated due to the aforementioned circumstances, it can only be reactivated by changing the gear range. If the vehicle is already outside of the calculated driving route, it must be manually guided into a starting position from which a new driving route can be calculated. Alignment in the parking space Delimitation at the side of the parking space is established by a recognized obstacle e.g. a curb or pole. If a lateral obstacle is not recognized, the vehicle is aligned flush to the front or rear obstacle. If the vehicle is positioned in the parking space on an angle, this is corrected by the parking system with a maximum of five maneuvers. The wheels are straightened once the parking procedure is completed. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – The Night View Assist system with (code 610) provides a visual representation of the road in darkness, with the aim of identifying people, obstructions or other objects before they become visible in the light cone of the conventional driving lights. The Night View Assist system is activated by pressing the Night View Assist button beside the rotary light switch. In addition, the following function requirements must be fulfilled and registered by the Night View Assist control unit: • Rain/light sensor detects twilight or night • Exterior lights switch in position "A" or " Manual driving lights" • Reverse gear not engaged • Vehicle speed v < 260 km/h "Intelligent Nightview" With the advanced "Intelligent Nightview" function (night view with pedestrian detection), pedestrians on dark country roads outside urban areas can be detected by the system. Detected pedestrians are highlighted by frame corners on the Audio/ COMAND display. Pedestrians can be detected at ranges up to 90 m in front of the vehicle. In addition to the function requirements listed above, a prerequisite for night vision with pedestrian detection is that the multifunction camera behind the windshield, which is located to the left side of the Night View Assist camera, must register darkness. Driving assistance systems Night View Assist Depending on the ambient brightness, the Night View Assist system makes a distinction between the two operating modes of twilight mode and night mode. In twilight mode, only the images recorded by the Night View Assist camera are displayed on the Audio/COMAND display. In night mode, the left infrared light and right infrared light in the respective front lamp units are additionally switched on as of a vehicle speed of v > 15 km/h. LEDs are used to generate the infrared light. The road in front of the vehicle is illuminated with infrared light up to a distance of 150 m. The picture from the infrared camera is displayed as a black/white video image in the audio/COMAND display. The area displayed corresponds roughly with the area visible through the windshield with the high beam switched on.

Japan-version vehicles are equipped with an expanded reversing camera system. Power is supplied by the reversing camera control unit. The reversing camera system can be activated and deactivated via the COMAND controller unit. In the system settings, "Autom. on in reverse gear" must be selected for this purpose. In the system for Japan, the reversing camera control unit superimposes guidelines over the video pictures output in the audio/COMAND display. With the aid of these lines the driver can maneuver the vehicle until he has reached the desired parking position. If the COMAND controller unit is switched off and reverse gear is then engaged, the COMAND controller unit is woken and images from the reversing camera are transferred. If another gear range is then selected, the COMAND controller unit switches to the audio mode last selected before the audio equipment was switched off. The reversing camera power supply module provides the reversing camera with power. The pictures taken by the reversing camera are sent as a Composite Video Baseband Signal (CVBS) over the reversing camera power supply module to the COMAND controller unit. The COMAND controller unit then activates the Audio/COMAND display over the telematics CAN (CAN A). The pictures taken from the reversing camera are then sent directly via the low voltage differential signal (LVDS) line to the Audio/ COMAND display and output there. The reversing camera system is automatically switched on when gear range "R" is engaged if the reversing camera function has been activated in the COMAND controller unit. The central operating unit then provides two parking modes to choose from, for which guidelines are superimposed on the picture. The mode that was active the last time the car was reversed is displayed as the default. The following options can be selected: • Right angle parking (reverse parking) • Lengthwise parking (parallel parking) Voice assistance can be activated when parallel parking. The images recorded by the reversing camera are read in and processed as CVBS signals by the reversing camera control unit. It also makes calculations based on the steering angle and the stored vehicle guideline parameters, which are shown on the pictures taken. The processed images are transferred to the COMAND controller unit as CVBS signals and from there to the Audio/COMAND display over the LVDS line. i Note (Japan version only) When performing initial startup/work on the reversing camera or work on the trunk lid, the reversing camera control unit must be recalibrated with the diagnostic tester. 106 b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – The DISTRONIC PLUS driver assistance system (code 233) automatically regulates the vehicle speed and distance to the vehicle in front as specified by the driver in the speed range of v = 0 to 200 km/h and v = 200 to 0 km/h. ® The PRE-SAFE brake continuously evaluates the risk of a rear-end collision and, in critical situations, initiates appropriate measures for collision warning and, if necessary, to reduce the severity of the collision. The BAS PLUS function (Brake Assist System PLUS), assists the driver through situation-dependent, targeted brake force calculation during emergency braking. DISTRONIC PLUS DISTRONIC PLUS uses the short-range radar sensor system integrated in the bumper and the long-range radar installed in the radiator grille in order to detect vehicles and obstacles ahead of the vehicle. The DISTRONIC PLUS functions are controlled by the video and radar sensor system control unit, which actively intervenes in the engine control system and brake system for this purpose. In addition, it controls the instrument cluster to output visual and acoustic warning messages. When the vehicle leaves the protected zone, the short-range radar sensor system is switched back on. If DISTRONIC PLUS is active, the message "DISTRONIC PLUS available again" is displayed. In vehicles for Australia, the radar sensor system must be manually switched off and back on via the onboard computer. The long-range radar operates in the 77 GHz frequency range, and at a detection angle of 18°, monitors the area in front of the vehicle up to a distance of 60 to 200 m. The area from 0 to 60 m in front of the vehicle is monitored at an angle of 60°. Driving assistance systems DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake The long-range radar operates using the PulseDoppler principle. This allows distances and speeds of individual objects to measured independently of each other. The maximum positive acceleration for automatic distance control which can be requested by the system is limited to approx. 2.5 m/s2 for safety and comfort-related reasons, the negative acceleration is limited to 40% of the maximum possible braking power. Due to legal requirements related to the 24-GHz radar system, the short-range radar sensor system is shut off in certain protected zones around radio astronomy stations. The protected zones are stored in the video and radar sensor system control unit in the form of Global Positioning System (GPS) coordinates. The current GPS coordinates received by the navigation system are transmitted via the front SAM control unit to the video and radar sensor system control unit. This shuts off the short-range radar sensor system when the vehicle is in a protected zone. If DISTRONIC PLUS is active, the message "Radar sensor system autom. shut off see operating instructions" is displayed on the multifunction display.

Activation is carried out by operating the cruise control lever on the steering column tube module and the desired speed can be set in steps of v = 1 km/h or 10 km/h. 108 A Long range radar (up to 200 m, detection angle of approx. 18°) B Middle detection range of long range radar (up to 60 m, detection angle of approx. 60°) C Short range radar (up to 30 m, detection angle of approx. 80°) i Note During downhill driving, the system also automatically intervenes in the brake system to keep the speed in the selected range. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – Automatic distance control As an additional function requirement for automatic distance control, the cruise control lever must be in the DISTRONIC PLUS position and a target object (vehicle in front) must have been detected by the radar sensor system. As soon as the target object has been detected, the distance selected with the DISTRONIC control is realized. The distance to the target object can be set in seven steps between approx. t = 1.0 and 2.0 s. The time specifications for the specified distance refer to the distance which the vehicle covers at a certain speed. The distance to the target object is displayed in metric units on the multifunction display and should be at least 50% of the displayed speed value.when If the target vehicle accelerates to over v = 200 km/h or leaves the detection range of the radar sensor system, the automatic distance control function switches over to the automatic speed control function. The vehicle is set to the speed chosen by the driver. Automatic acceleration and braking The video and radar sensor system control unit determines the intensity of acceleration or deceleration of the systems vehicle in the longitudinal direction as well as the movement and speed of the target vehicle. If the target object is detected by the radar sensor system, the DISTRONIC controller unit evaluates the target data and transmits the relevant information to the video and radar sensor system control unit. This transmits a request to raise or reduce the engine speed via the ESP control unit to the CDI control unit or ME-SFI [ME] control unit. The driver is able to intervene in the vehicle acceleration process via the accelerator pedal. Automatic acceleration is suppressed as long as the driver is accelerating using the accelerator pedal. This process is indicated on the multifunction display with the message "DISTRONIC passive". If the specified distance cannot be set by reducing the engine speed, the video and radar sensor system control unit transmits a braking request to the ESP control unit. This implements the request through controlled actuation of the traction systems hydraulic unit. Driving assistance systems DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake Automatic startoff The regulated start-off function of DISTRONIC PLUS enables automatic start-off and stopping in stopand-go traffic. This function is only carried out if acknowledged by the driver by pressing the resume from memory switch after he or she has released the brake pedal. Actuation of the brake pedal is recorded by the brake lights switch, whose signals are read in by the ESP control unit. Standstill coordinator For safety reasons, the system also continuously checks, in addition to the function requirements, whether the driver is present in the vehicle. Driver detection takes place via the standstill coordinator, which is integrated in the Electronic Stability Program control unit. This monitors whether the driver door, driver seat belt buckle, front passenger door and engine hood are closed. Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service. Status: 09 / 2010 – 109 Driving assistance systems DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake PRE-SAFE® brake The PRE-SAFE® brake is only available on vehicles with DISTRONIC PLUS. The PRE-SAFE® can help to minimize the risk of a rear-end collision with the vehicle in front or to reduce the consequences of an accident. In the low speed range below v = 30 km/h, the function is designed so that the PRE-SAFE® brake can prevent accidents. In the speed range of v = 30 to 200 km/h, the PRE-SAFE® brake is intended to minimize the severity of collisions. The PRE-SAFE® brake uses the radar sensor system to detect obstacles which remain in the path of the vehicle for an extended period of time. If the vehicle approaches a detected obstacle and the PRE-SAFE® brake detects a risk of a rear-end collision, the system first issues a visual warning (DISTRONIC warning lamp) and acoustic warning (intermittent tone). If the driver then does not brake or take evasive action, the system warns through gentle automatic braking of the vehicle with approx. 40 – 60 percent of the maximum braking power. In the speed range below v = 30 km/h, this can be enough to avoid a collision. The driver and front passenger must have their seat belts fastened for autonomous brake system intervention to take place. If there is still a risk of a rear-end collision and the driver does not brake, take evasive action or accelerate significantly, automatic emergency braking can take place. Automatic emergency braking is only initiated directly before an accident which is no longer avoidable. Automatically triggered emergency braking cannot prevent a collision. 110 The PRE-SAFE® brake can react to stationary obstacles, e.g. stopping or parking vehicles, at a vehicle speed of up to approx. v = 70 km/h. In the speed range over v = 30 km/h, PRE-SAFE® activates preventive occupant protection measures if there is an increased risk of a rear-end collision. Dynamic distance warning As of a speed of roughly v = 7 km/h, this function warns the driver if the vehicle approaches the vehicle in front very quickly. An intermittent alarm tone is output and the DISTRONIC warning lamp on the instrument cluster lights up. Static distance warning As of a speed of roughly v = 30 km/h, this function warns the driver when the distance to the vehicle in front is too short for the speed being driven over a period of several seconds. The DISTRONIC warning lamp on the instrument cluster then lights up. This function is not active when DISTRONIC PLUS is switched on. Switching on and off: The PRE-SAFE® brake can be switched on or off using the onboard computer. The distance warning readiness indicator appears on the lower multifunction display as long as the HOLD function is not switched on. On vehicles with Parking Guidance, the symbol is displayed when gear range "P" is engaged or the vehicle is driving quicker than v = 35 km/h. b Introduction of the New CLS-Class, Model Series 218 Coupe – This printout will not be recorded by the update service. Status: 09 / 2010 – BAS PLUS BAS PLUS is only available in vehicles with DISTRONIC PLUS. BAS PLUS assists the driver when braking in hazardous situations at speeds of v > 7 km/h and uses the radar sensor system to evaluate the traffic situation. BAS PLUS uses the radar sensor system to detect obstacles which remain in the path of the vehicle for an extended period of time. BAS PLUS can also react to stationary obstacles, e.g. stopping or parking vehicles, at a vehicle speed of up to approx. v = 70 km/h. If the vehicle approaches an obstacle and BAS PLUS has detected a risk of a rear-end collision, BAS PLUS calculates the required brake pressure to avoid a rear-end collision. If the driver depresses the brake forcefully, BAS PLUS automatically increases the brake pressure to the appropriate value for the traffic situation. If BAS PLUS requests a particularly high brake pressure, preventive occupant protection measures (PRE-SAFE®) are activated simultaneously. Driving assistance systems DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake The brake returns to normal operation when • The brake pedal is released • No obstacle is detected in the path of the vehicle • A risk of a rear-end collision is no longer detected.

The Music Register in the COMAND APS supports the MP3 format. The following head units are installed depending on the equipment version and national version: For ECE: • • • • • • Audio 20 (code 523) Audio 20 including CD changer (code 510) Audio 50 APS (DVD) (code 525) Audio 50 APS including DVD changer (code 511) COMAND APS (with navigation) (code 527) COMAND APS including DVD changer (code 512) For (code 498) Japan version: • COMAND APS (with navigation) (code 527) For (code 494) USA version: • COMAND APS including DVD changer (code 512) • COMAND including DVD changer (code 528) Bluetooth® audio (only in combination with COMAND) With this new function, the COMAND controller unit can receive audio signals from external devices via Bluetooth®. Playback takes place via the speakers of the audio system. External devices must be authorized as an audio source. The prerequisite is that the device must support Audio Video Remote Control Profile (AVRCP) or Advanced Audio Distribution Profile (A2DP). Communication takes place via the Bluetooth® antenna in the overhead control panel. The display of information about the audio data on the Audio/COMAND display and multifunction display of the instrument cluster depends on the transmission profile supported. Extended information such as track, album and artist are displayed as of version 1.3 of the AVRCP profile. Telephony AUX IN jack Irrespective of the particular audio unit, an AUX-IN jack is installed in the center console stowage compartment (front armrest) as standard. This can be used to connect external devices (e.g. MP3 player) to the audio system of the vehicle. The AUX IN jack is omitted on vehicles with media interface (code 518). Media interface (code 518) The media interface special equipment option replaces the AUX-IN jack with a universal interface. This allows mobile audio devices (e.g. MP3 player, iPod) to be connected and video data to be transmitted in combination with COMAND. The required adapters are included with the vehicle. The unit is operated via the button groups on the multifunction steering wheel, the head unit buttons, the Audio/COMAND control panel or via the LINGUATRONIC voice control system. 112 Basic telephony supports the connection of the mobile phone via Bluetooth® using the Hands-Free Profile (HFP). The comfort telephony special equipment option (code 386) contains a Bluetooth® module under the armrest in the center console. This module allows a mobile phone to be connected directly via a telephone-specific cradle. Comfort telephony thus offers the additional functions of charging the mobile phone, using the external vehicle antenna and downloading SMS and contact data over a serial interface. With both versions, the telephone can be operated via the button groups on the multifunction steering wheel, the head unit buttons, the Audio/COMAND control panel or the LINGUATRONIC voice control system. Voice output takes place via the front speakers.

Status: 09 / 2010 – All the components of the bodywork have been redesigned for model series 218. The most important features considered in the development of the bodyshell of the new CLS-Class include: • Further improvements in the rigidity and strength of the passenger cell • Specifically developed deformation zones in the front and rear end structures • Ease of repair due to detachable front and rear end assemblies with a simultaneous reduction in the weight through the use of an extruded aluminum section (at the front) and high-strength steel (at the rear) • Good installation conditions for drive assemblies and the front axle thanks to the bolted frame-type integral support • The use of MIG soldering means that MAG weld seams can be dispensed with completely. This has significantly improved the quality of manufacture and resistance to corrosion • The proportion of high-strength sheet steel in the bodyshell has risen from 45% to 72% by weight, with newly developed steel grades being increasingly used Sheet steel was selected as the material for the vast majority of the bodyshell. The front fenders, the engine hood and the trunk lid are made of aluminum. Aluminum thus makes up 8% of the bodyshell by weight. A high-strength steel frame-type integral support holding the front axle, steering and engine is bolted onto the front longitudinal members. The spare tire well is made of glass fiber matting-reinforced thermoplastics (GMT). Body Bodyshell components Front end The front structure of model series 218 is a front end assembly mounted on the vehicle, which consists of: • An extruded aluminum section • A single-part aluminum crash box connecting the front longitudinal members • A multi-piece framework of glass-fiber reinforced plastic and aluminum sheet for holding the headlamps, the bumper, the washer fluid reservoir and the engine hood catches The entire front end assembly is bolted to the front end structure, as are the individual components of the front end assembly to each other. If any parts are damaged, this makes it possible to replace them inexpensively and with no welding required. The connection of the front end to the passenger cell is now made with four instead of three (predecessor) combined sheets. Passenger cell The core of the body safety concept is the highstrength passenger cell in the form of a safety cage. Its high strength under the stresses of an accident (frontal, side-on and rear-end collisions as well as rollovers) is primarily due to: • The increased use of high-strength, modern highstrength, ultra high-strength and heat-formed ultra high-strength sheet steel and panels with graduated wall thicknesses • Components and structural zones susceptible to heavy loads in accidents which incorporate materials and sheet thicknesses designed to resist these loads • Optimized shapes and cross sections Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service. Status: 09 / 2010 – 117 Body Bodyshell components Doors Rear end The door shells, including the side window frames, incorporate an inner two-piece sheet aluminum shell with external reinforcements (extruded sections and deep-drawn parts). As in the current E-Class, the hinge-bearing panel is separate from the inner shell. This makes it possible to use a thicker panel to improve the distribution of forces in the area of the hinge with only a low weight penalty. In the new CLS-Class, the locations of the independent multilink rear suspension, the fuel tank and the spare tire well are similar to those in the predecessor model. Nevertheless, the geometry of the body structures at the rear end is different. This applies particularly to the design of the structures in the vicinity of the through-loading hole in the rear wall of the passenger cell, the rear longitudinal members, the spare tire well and the rear end assembly. To improve the rigidity and strength of the doors, reinforcement profiles are welded on at the frames and at the beltline. The deformation depth in side-on collisions is reduced and dent resistance is improved by two additional extruded sections which run diagonally and in the longitudinal direction and which are spotwelded and glued into the doors. The fasteners for the backrest and for the hinges and catches on the folding backrest (special equipment) of the rear bench seat are mounted on an all-round support structure which is welded to the inner shell of the side wall on both sides and to the floor panel at the bottom, and is clinched to the rear shelf at the top. This supporting structure further improves the torsional strength of the bodyshell. To increase their strength, enhance their strain energy and improve their deformation behavior, the multipart, high-strength steel rear longitudinal members have a cross section which is closed along their entire length with graduated sheet thicknesses, as in the predecessor model. The rear end assembly consists of a steel flexural member with integral deformation zone. Weight is optimized through the use of ultra highstrength steel, which is flexibly rolled so that the areas subject to the greatest loads are thicker than those under lower stress. For reasons of weight and corrosion protection, plastic (glass fiber matting-reinforced thermoplastic) is used for the spare wheel well as in the predecessor model.

Status: 09 / 2010 – Floor Corrosion protection The floor of the passenger cell consists of a sheet metal part, with three parts connected to each other by laser welding prior to forming. The middle part is thicker and forms the transmission tunnel, acting as the backbone of the floor system. Additional solid tunnel reinforcements are placed on top. Full-length longitudinal floor members are now installed to improve force progression into the floor structure. To the left and right of the tunnel it is reinforced from the inside with: Long-term protection against corrosion is guaranteed by full galvanization of the steel body components. Structural areas that are particularly susceptible to corrosion are protected by additional cavity preservation. • Reinforcements between the inner shell of the front longitudinal members and the tunnel, and between the tunnel and the side longitudinal members • A rigid crossmember for mounting the seats and for lateral support on the tunnel in the event of a side collision • A further crossmember in the area of the B-pillar As in the predecessor model, the junction with the rear floor assembly is formed by a continuous rear seat crossmember with additional reinforcements which is extremely strong with regard to side collisions. Body Bodyshell components To supplement this, the following protective measures are used in addition to regular galvanizing in the manufacture of the sheet steel: • Use of organically coated sheet steel • Cataphoretic immersion primer bath • Seam sealing Underfloor protection Because the underfloor area is entirely covered with penta laminate, it was possible to omit the PVC underfloor protection. The advantages are: • Lower aerodynamic drag • Interchangeability if damaged (ease of repair) • Detachability for vehicle recycling • Increased impact resistance (stone chipping protection) P61.45-2051-00 Underfloor paneling Introduction of the New CLS-Class, Model Series 218 Coupe b – This printout will not be recorded by the update service.
