Status: 06/2014 – 7 Overview Models and major assemblies Overview Brief description Vehicle concept The new smart is being introduced in November 2014 as the successor to model series 451. The new smart is available as the smart fortwo coupé (C453) and smart forfour (W453). In order to take individual customer preferences into account, the new generation of the smart features a "lines" concept. Starting with the standard equipment, customers will have the option of customizing their vehicle with three additional lines which incorporate both technical and design variations. The drivetrain concept is based solely on the three-cylinder gasoline engines which are installed at the rear end of the vehicle. Dimensional concept The new smart fortwo coupé and the new smart forfour renew and expand the smart product range in the segment of micro-compact vehicles. The proportions of the predecessor generation have largely been retained. Accordingly, the twoseater smart fortwo coupé has the same vehicle length of 2.69 m. The smart forfour contains the same features as the smart fortwo coupé, the sole differences being a longer wheelbase, an extended tridion safety cell and four doors instead of two. bbNote Further information on the electrical systems in model series 453 (e.g. function descriptions and locations of electrical components) is available in the Workshop Information System (WIS) under the Basic Knowledge/Functions (GF) information type. 8 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

Status: 06/2014 – Front Now in its third generation, the smart has a more mature overall appearance and yet remains unmistakably smart. Typical features of the brand include the graphic elements separating the components through a dual color scheme and the striking tridion design in conjunction with the compact front and rear ends. Front view of smart fortwo coupé P00.00-5254-00 The previous "onebox" proportions have been slightly changed in the area of engine hood height in order to improve active/passive safety. Simply changing the angles at the front end has improved pedestrian protection, which is of particular importance in urban traffic situations. The refined radiator grille looks like an integrated net, which is smoothly amalgamated into the front-end design. The new headlamps with their design principles and clear glass lenses emphasize the newfound maturity of this vehicle generation.

Status: 06/2014 – P00.00-5253-00 19 Overall vehicle Vehicle views Overall vehicle Vehicle views Rear end At the rear end of the new smart fortwo coupé, the raised lettering on the lower part of the split liftgate indicates the brand identity. As on predecessor models, the separation of the upper and lower parts provides loading versatility for both light and heavy items. The top edge takes the form of a roof spoiler with integrated center high-mounted brake lamp. In principle, the smart forfour features the same design elements as the smart fortwo coupé. However, it has a onepiece, upward-opening liftgate with smart logo, which also accommodates the reversing camera special equipment. On this variant, the license plate is fitted to the dual-color bumper. The rear lamps, which are set into the tridion safety cell, give the design a particular sense of quality and underline the width of the vehicle at the rear end. The license plate is mounted between the lamps in the liftgate. The bottom edge of the bumper, which is painted in the vehicle color, is black and has a cutout on the left (viewed in the direction of travel) for the visible tailpipe of the exhaust system. A sport exhaust tip is available for the exhaust system, while the bumper also houses the distance sensors.

Status: 06/2014 – Side The most noticeable difference between the two-seater and four-seater is found at the side: The smart fortwo coupé has large doors, which extend into the B-pillar, and frameless windows. The door contour and the tridion safety cell reflect the smart design genes even when viewed from some distance, which is what makes the vehicle so unmistakable on the road. The brand image is further enhanced by a characteristic swage line on each vehicle, positioned roughly in the center of the doors. These features are further complemented by the tank cap on the right and the air inlet for the rearmounted engine on the left underneath the B-pillar. Side view of smart fortwo coupé P00.00-5258-00 The side view of the four-seater reveals the same elements as the two-seater, but with two additional doors and a longer tridion safety cell. The front and rear overhangs have an identical appearance to those of its little brother. The range of wheels extends from steel wheels through to exclusive light alloy wheels (15 and 16-inch) in monochrome or high-sheen machined versions.

Here, the age and mileage of the vehicle are taken into account for the service scopes. In addition, use of the DSB (Digital Service Booklet) by workshops will also be possible at market launch in those countries which already offer it for Mercedes-Benz cars. Another area where maintenance has been harmonized with Mercedes-Benz cars is in the changes to "Oil Service Plus" and "Maintenance". Like Mercedes-Benz cars, smart maintenance now also consists of an alternating Service A and B as well as an optionally available "customer package". The following fixed maintenance intervals apply, with the exception of possible country-specific variations in the kilometer intervals: • Service A after 20,000 km or one year • Service B after 40,000 km or two years Maintenance interval display (WIA) The maintenance interval display is located within the multifunction display of the instrument cluster. It shows the remaining distance (in km/mi) or the remaining time (in days) until the next service. The number of wrenches indicates the type of service due. The symbol with one wrench means Service A and the service with two wrenches means Service B. If a service is due within the next 1500 km or 30 days, the driver is notified of this on the instrument cluster every time he or she restarts the vehicle in the form of a wrench symbol which flashes for 10 seconds. On equipment lines with TFT display, a text message appears on the screen. Once the service has been completed, the service interval display can be reset either using STAR DIAGNOSIS or directly on the instrument cluster.

P27.00-2443-00 twinamic 6-speed dual clutch transmission 52 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – Shift mechanism On the twinamic 6-speed dual clutch transmission, the engine torque is transferred from the crankshaft of the combustion engine to a two-mass flywheel. From there, the power flows to the internal shaft or external shaft of the dual clutch transmission depending on the clutch engaged. A single-cone carbon synchronizer is used to synchronize the first, third, fourth and reverse gear. A double-cone sintered synchronizer is used for the second gear. Synchronization of the fifth to the sixth gear is carried out with a single-cone sintered synchronizer. The transmission operates without an additional oil cooling system. 1 Process During driving operation, a gear is always engaged in each of the two sub-transmissions. The gear which is expected to be engaged next is pre-engaged in the second sub-transmission by the transmission control system. The clutch for the gear currently in use is engaged, while that of the gear which is expected to be used is disengaged. To change gears, clutch 1 (currently engaged) is opened, while clutch 2 is engaged. Summary The dual clutch transmission operates without any interruption of tractive power. If necessary, the electronic control system skips individual gear ranges instead of downshifting the gears one after the other. It thus provides the convenience of an automatic transmission combined with the efficiency of a manual transmission. 2 P27.00-2444-00 Shift mechanism of dual clutch transmission 1 1st gear Sub-transmission 1: 1st, 3rd, 5th gear 2 2nd gear Sub-transmission 2: 2nd, 4th, 6th, R gear Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

The main advantages of this front axle design include: • Small space requirement • Low unsprung masses • Large support base • Low forces Wheel control on each wheel is performed by a transverse control arm below wheel center, a suspension strut and a tie rod. The focus during the redevelopment of the front axle of model series 453 was on achieving a high level of driving safety, a high level of manoeuvrability and improved ride comfort compared to the predecessor model series. A high level of driving safety was achieved through the design of the axle kinematics and by adjusting the tuning. To improve the ride comfort, the spring travel both at the front axle and at the rear axle was increased. The newly developed front axle is now equipped with a transverse control arm with one guide bearing and one comfort bearing respectively, which produces greater longitudinal flexibility and improved suspension response. In order to achieve the desired reduction in the turning circle, the front axle was designed to allow very large outside wheel turn angles. This necessitated a suitable integral carrier design, long toothed rack travel distances and suitable tie rod kinematics. 6 2 3 1 4 P33.00-2144-00 Front axle of smart model 453 1 Transverse control arm with supporting joint 4 Wheel carrier 2 Integral carrier 5 Coil spring (side load spring) 3 Stabilizer bar 6 Twin-tube gas-filled shock absorber 56 5 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – The front axle integral carrier is larger compared to that of the predecessor model series and, with its extended support base, not only holds the guide and comfort bearings of the transverse control arm, but also the steering. It also serves as the crash element for the third (lower) plane. The component is designed on a load-dependent basis. Rear axle Like model series 451, model series 453 is equipped with a De Dion rear axle directly mounted to the bodyshell with lateral support from cross struts. The use of this axle design made it possible to develop a rear axle with competitive features in spite of the relative lack of available space due to the rear-mounted engine. The rear axle carrier taken over from the predecessor model series was integrated into the bodyshell for weight-optimization reasons. The De Dion rear axle of the new smart is thus mounted directly on the body. 7 6 3 1 2 5 4 P35.00-2122-00 Rear axle of smart model 453 1 Axle tube 5 Coil spring 2 Twin-tube shock absorber pin bearing 6 Center bearing 3 Rear longitudinal member (bodyshell structure) 7 Bar link 4 Twin-tube damper Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – 57 Chassis Axles and suspension Chassis Axles and suspension Suspension and damping The suspension of the new smart consists of twin-tube MacPherson suspension struts on the front axle and twin-tube shock absorbers with separate springs on the rear axle. Front axle suspension The front axle consists of MacPherson suspension struts for wheel control, consisting of coil springs optimized for transverse forces, auxiliary springs, twin-tube gas-filled shock absorbers and compact support bushings. The support bushing has a three-path design i.e. force application by the shock absorber, spring and auxiliary spring are decoupled from each other. The shock absorber is supported by the inner elastomer bearing, which is optimally tuned to the response characteristics of the shock absorber. The comfort-enhancing polyurethane auxiliary spring features a progressive characteristic and is supported against the body through the bearing housing. The force from the coil spring is transferred through the ball bearing to the body. View of support bushing P32.00-2076-00 Noise insulation is achieved by means of a bottom spring mount made of elastomer. In order to reduce friction in the seal guide unit of the shock absorber, the coil springs are geometrically designed as "side load springs", which compensate for the effect of the vertical wheel force on the transverse force in the seal guide unit. This produces optimized shock absorber response characteristics. The suspension strut features a clamping bracket for assembly-related reasons, a large spring retainer with spring catching function and a weight-reduced hollow piston rod. The torsion bar also has a tubular design for weight-related reasons, with torsion bar mounts vulcanized onto it. 58 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – Rear axle suspension A new feature of the De Dion rear axle are the twin-tube shock absorbers with separate, barrel-shaped coil springs. Effective noise insulation of the coil springs between the body and rear axle is achieved by means of two elastomer shims. The shock absorber is connected to the body by a pin bearing. This has a soft cardan bearing which contributes to a reduction of friction in the shock absorber and thus an improvement in response characteristics. The location and ratio of the shock absorbers provides suspension tuning with a favorable compromise between damping of roll and pitch. In addition, the deliberate inclination of the shock absorbers produces longitudinal damping of the axle. Suspension variants A standard and a sports suspension are available for the new smart. On the standard suspension, longer spring travel distances, a friction-optimized supporting length and precise lateral force compensation create the prerequisites for comfortable suspension behavior. The sports suspension available as special equipment features tighter front and rear axle springs and the vehicle level is lowered by 10 mm at the front and rear axle compared to the standard suspension.

Status: 06/2014 – P32.00-2077-00 59 Chassis Axles and suspension Chassis Steering Steering The new smart is equipped with a mechanical rack-and-pinion steering gear as standard, which is located in front of the wheel center position. An electric steering assist system with variable steering assistance is available optionally. The newly developed electric steering assist system of model series 453 is designed as a direct steering system with variable gearing. For minor steering movements, the steering has a more indirect design which improves straight-ahead running. In the medium steering angle range encountered during normal urban driving, the steering ratio increases and the customer has to move the steering wheel through a reduced angle e.g. when turning or maneuvering. Compared to a conventional hydraulic solution, electric steering force assistance offers the following advantages: • No hydraulic fluid necessary • Fuel saving due to greater efficiency • Improved steering feel • Optimized assembly process • Active return improves steering centering • Diagnosis capability The electric steering power assistance system consists of the rack-and-pinion steering gear, torque sensor, actuator motor and control unit. BBRepair information When removing/installing the steering gear, all the fasteners (bolts, nuts and triangular brackets) must be renewed. A parts kit for this is available in the EPC. 3 2 4 5 1 2 P46.35-2121-00 Electric power steering of model 453 1 Rack-and-pinion steering gear 4 Electric power steering actuator motor 2 Tie rod 5 Electric power steering torque sensor 3 Electrical power steering control unit (N68) 60 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

However, finite installation space and efforts to lower vehicle weight make conventional data transmission methods impossible. This is why the use of bus systems is required. In the new smart, the vehicle electronics are networked via the following data bus systems: • Telematics CAN • Interior CAN • Drive train CAN • Chassis CAN • Front end CAN • AC operation LIN • Rain and light sensor LIN • Additional instruments LIN Gateway Control units with gateway function are linked with two or more data bus systems. This means that they can send and receive signals to and from several bus systems. Control units with gateway function: • ME-SFI control unit • Audio gateway control unit • Electronic Stability Program control unit • Telematics services communications module • Distance warning function gateway Fuses The maxi and ATO fuses that are accessible for the customer are located in the following positions in the vehicle: • Fuse box in front compartment under service flap • Fuse box in glove compartment On-board electrical system battery The 12 V on-board electrical system battery of size H5 is located in front of the passenger compartment under the front hood on all models. The data transfer rate of the CAN bus systems in the new smart is 500 kBd. bbNote The procedures for disconnecting the battery are documented in the Workshop Information System (WIS).

The automatic start/stop function shuts off the engine automatically when the vehicle stops if the relevant conditions are fulfilled. The engine then restarts automatically to drive off again. The driver-side SAM control unit acts as the master control unit for the automatic start/stop function. It prompts the MESFI [ME] control unit to stop or start the engine depending on incoming sensor data and the data which it receives from the center SAM control unit, Electronic Stability Program control unit, climate control control unit and Supplemental Restraint System control unit. The output device for start/stop system messages is the instrument cluster. Conditions for automatic engine stop For the automatic start/stop function to automatically shut off the engine, the driver must brake the vehicle to a standstill, put the vehicle into neutral and release the clutch pedal or select gear range N. If the following conditions are also met, the engine is shut off and the ECO start/stop function "available" indicator lamp lights up on the instrument cluster: • Engine is at operating temperature • Driver door is closed and driver seat belt is fastened • Battery is sufficiently charged • Temperature in vehicle interior corresponds to setting • Outside temperature is within a suitable range for the system • Automatic start/stop indicator lamp is not on • Liftgate is closed Conditions for automatic engine start The engine is started automatically when • The driver depresses the clutch pedal • The automatic start/stop function is switched off via the automatic start/stop button • The temperature in the vehicle interior is no longer within the set range If all of the conditions for an automatic engine start are not fulfilled, the ECO start/stop function "not available" indicator lamp lights up. 70 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

Protective measures for pedestrians Reducing the severity of accidents is particularly important for collisions with weaker road users without crumple zones e.g. pedestrians. In addition to the active measures which help to avoid accidents or minimize the severity of accidents, the passive pedestrian protection measures on the new smart have also been further optimized. For example, to reduce the loads that occur during an impact on the front hood of the vehicle, the deformation clearances between the front hood and the components underneath have been optimized. The deformation properties of the front hood were developed specifically to meet these requirements. The design of the front of the vehicle has produced a more favorable, larger impact area. In combination with the structural design of the front bumper, this reduces the stress applied if the vehicle collides with the legs of a pedestrian.

The forward displacement areas for the occupants are designed so that there is a suitable deceleration travel distance for the occupants in the event of a collision in order to keep accident stresses as low as possible. Seat belts The driver and front passenger seats are each equipped with a three-point seat belt with belt force limitation and pyrotechnical emergency tensioning retractor as standard. On the sedan, the outer rear seats are equipped with a three-point seat belt with seat belt retractor with tensioning and belt force limitation. The center seat has a three-point seat belt of standard design. In the USA and Canada, the C453 is additionally equipped with anchor fitting tensioners and two-stage, switchable belt force limiters for the driver and front passenger. Child restraint systems The ISOFIX system incl. Top Tether connection, which allows certain child seats to be connected to the vehicle, is provided as standard equipment on the front passenger seat and, on the sedan, on the rear seats. Driver/front passenger airbag, kneebag The smart is equipped with a driver airbag, driving kneebag and front passenger airbag as standard. The gas generators for the driver airbag and front passenger airbag operate on a single-stage basis. The kneebag has a positive influence on occupant kinematics in the event of a frontal impact and thus offers the driver additional protection potential in many frontal impact situations. In the USA and Canada national versions of the smart fortwo coupé, two-stage driver and front passenger airbags are used. The front passenger airbag is equipped with an additional third pyrotechnical unit in order to adjust the hardness of the airbag to the particular load case and occupant. A front passenger kneebag is also installed in these national versions. Sidebags The sidebags (head/thorax bags) are standard equipment and are located in the backrest of the driver and front passenger seat. They cover the head and chest of the respective occupants from the side. When triggered in side collisions, they can minimize the loads applied to the chest area and reduce the risk of the occupant's head directly hitting the side window or dangerous objects e.g. power poles, trees or parts of a colliding vehicle. The sidebags are triggered on the impact side if the central electronic unit detects a side crash of a certain severity level. Furthermore, emergency tensioning retractors are triggered on both the impact side and the opposite side (depending on the seat belt status on the USA national version). A reel tensioner and anchor fitting tensioner on the impact side and the opposite side are additionally triggered on the USA national version. On the USA and Canada national versions of the smart fortwo coupé, thorax/pelvis airbags and window airbags are used instead of the head/thorax airbags (same integration, different protection area). The window airbags cover the whole area between the A and B-pillar at the sides. 76 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – Restraint system control unit The smart is equipped with an electronic control unit which triggers restraint systems depending on the expected impact severity. On the USA and Canada national versions, two upfront sensors are installed additionally on the flexural member at the front end. In order to better detect side impacts, the central crash sensor is supported by satellite sensors in the area of the B-pillar base and by pressure sensors in the front doors. Depending on the seat occupancy detection status and seat position detected via the seat position switch, the seat occupied recognition system can suppress or adjust airbag triggering on the passenger side on the USA and Canada national versions. Seat position switches control the switchable belt force limiters and activation of the ventilation valve by a squib in the front passenger airbag. A seat belt buckle switch monitors the belt status at each position: "engaged" or "not engaged". A visual/acoustic seat belt reminder warning function is provided for the two front seats depending on the country. The indicator lamp is located in the instrument cluster. The front passenger seat has a seat belt reminder mat. The indicator lamp for the rear seats is located in the overhead control panel.

Status: 06/2014 – Cruise control with variable speed limiter smart model series 453 is equipped with a cruise control function which maintains a preset speed and an additional variable speed limiter function which helps the driver to avoid exceeding a speed. The variable speed limiter function can be adjusted via the multifunction steering wheel. The cruise control with variable speed limiter is standard equipment on all vehicles irrespective of the engine/transmission combination. Excepted from this are the USA and Canada national versions, on which the cruise control function is only available without variable speed limiter function. Crosswind Assist The new smart is equipped with the Crosswind Assist function as standard. This system helps the driver by significantly weakening any influence on the straightahead running of the vehicle caused by strong crosswind. The vehicle's deviation from its intended path and the steering effort required by the driver are significantly reduced in this situation. The existing sensors of the ESP® system are used to detect interference from crosswind. Crosswind Assist is active as of 70 km/h and takes effect when driving straight ahead or during light cornering. Crosswind interference is compensated for by a single-sided brake system intervention initiated by the ESP® system. The customer benefit of Crosswind Assist is that the vehicle's deviation from its intended path and yaw response in heavy crosswind are reduced and the driver has to countersteer less.

Status: 06/2014 – 79 Driving assistance systems Systems at a glance Driving assistance systems Lane Keeping Assist Lane Keeping Assist The Lane Keeping Assist (LDW) system uses a camera in the area of the inside rearview mirror to detect when the vehicle crosses lane markings and warns the driver when the vehicle unintentionally leaves the detected lane. The warning takes the form of an acoustic warning and visual feedback (tell-tale) on the instrument cluster. Lane Keeping Assist (LDW) is active at vehicle speeds as of 70 km/h. The Lane Keeping Assist system is activated using a switch in the left switch panel next to the steering wheel. 1 P30.00-2011-00 View of Lane Keeping Assist camera 80 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – Tire pressure monitor The smart (C/W453) is equipped with directly measuring tire pressure monitor (TPM) as standard (not for all countries). On vehicles with tire pressure monitor, a sensor is attached to the valve on the inside of each wheel. While driving, the sensors transmit radio signals containing information about the pressure, temperature and rotation direction of the wheels as well as an individual identification number (to distinguish between sensors). The data which is transmitted via radio signal is received and evaluated by the SAM control unit via an integrated antenna. The tire pressure monitor issues a warning using an indicator lamp on the instrument cluster if the air pressure drops below a certain value. The TPM system has to be recalibrated when new wheels are installed.

The rear parking assist system helps the driver when reversing in tight conditions. With the aid of ultrasonic signals that are reflected by obstacles, an electronic control unit computes the distance between the vehicle and the detected obstacle. The signal transmitters and receivers are combined in the ultrasonic sensors and there are three sensors distributed along the rear bumper. There is a button to switch the function on and off positioned on the left next to the steering wheel. If the system detects an object within the monitoring range behind the vehicle while reversing, this is indicated by an acoustic warning. The time interval between tones provides an indication of the distance remaining to the detected object. The acoustic warning varies as the vehicle approaches from long intervals through to a continuous signal. When reverse gear is engaged with parking assist active, an acoustic notification tone sounds. 1 P54.65-5461-00 Location of ultrasonic sensors in bumper 1 82 Ultrasonic sensors Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

In technical terms, the system consists of a distance warning controller unit with radar sensor and the distance warning function gateway. Static distance warning A visual warning (warning lamp on instrument cluster) is triggered as soon as a vehicle is detected in front and a certain time gap between the vehicle in front is dropped below i.e. the following distance is too short. The static distance warning only operates for moving objects as of a systems vehicle speed of 30 km/h. Dynamic distance warning A dynamic distance warning is triggered if the systems vehicle approaches a detected vehicle in front at high speed or high acceleration relative to the vehicle in front. In this case, both a visual and an acoustic warning are issued. The dynamic distance warning only operates for moving/stopping objects at a maximum speed of 7 km/h and for stationary objects up to 70 km/h. Customer benefits The aim of the distance warning function is to inform an inattentive driver that there is a risk of a rear-end collision.

Interior protection Interior protection is activated approx. thirty seconds after the vehicle is locked. The customer can choose between two variants of the antitheft alarm system. • Anti-theft alarm system (code V19) • Anti-theft alarm system with interior monitoring and towaway protection (code 885) Using the ultrasonic sensors mounted centrally on the headliner of the vehicle, the ATA control unit monitors the incoming and outgoing wave patterns. If anything enters the vehicle without authorization, these change significantly and an alarm is triggered. On vehicles with code (V19), the SAM control unit is the master control unit for the anti-theft alarm system. Alarm output The alarm is output via the battery-buffered alarm horn. If the vehicle is locked with the transmitter key, the anti-theft alarm system function is activated. Drive authorization system The drive authorization system of the new smart represents a system network of the following components: • Center SAM control unit (N10/10) • Transponder coil (L11) • Vehicle key (A8/1) • ME-SFI [ME] control unit (N3/10) • Electronic Stability Program control unit (N30/4) • Dual clutch transmission control unit (N15/13) (with automatic transmission) When armed, the SAM control unit monitors the central locking microswitches of the vehicle doors, the liftgate and the ATA switch on the battery. If it detects a status change in the central locking microswitches or ATA switch on the battery, it actuates the turn signal lights and the horn. Vehicles with code (885) are equipped with ultrasonic sensors in the interior, a sensor for tow-away protection, a battery-buffered alarm horn and a controller unit. Tow-away protection If the position of the vehicle is changed, the ATA inclination sensor detects this and sends a message to the ATA control unit, which then triggers the alarm. If the key is turned to the position "Ignition ON" in the ignition lock, data is exchanged between the vehicle key and the transponder coil. The center SAM control unit receives the data of the vehicle key from the transponder coil and evaluates it. At the same time, the center SAM control unit initiates authentication of the Electronic Stability Program control unit and the dual clutch transmission control unit via CAN bus. If the authentication of both control units is successful and the vehicle key is recognized as belonging to the vehicle, the center SAM control unit sends an enable signal to the engine control unit. The vehicle can now be started. 96 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.

These relate to the changes in boundary conditions, such as the shared platform with the smart forfour, its production at various production locations and advanced technical requirements, particularly in relation to crashes (e.g. stricter rating requirements, USA). The development process took into account both the requirements of the powerplant variants with conventional combustion engine and the requirements of the subsequently planned variants with electric motor. Specific crash requirements for markets in Europe, Asia and America were also incorporated in the development process. The most important features of this shared platform include: • Special yielding crossmembers under the windshield • Center tunnel designed as a closed section • No longitudinal members under the main floor • Central connection of De Dion rear axle • Realization of a load stage through different mounting points for the integral carrier variants (for requirementbased adaptation to vehicle weight and crash design) • V-shapes as additional load path (smart fortwo only) 104 Each individual bodyshell element has been developed to suit the loads it will encounter in terms of its geometry, material thickness, joining technology and material quality. In contrast to the predecessor model series 451, the bodyshell of model series 453 has a greater proportion of ultrahigh strength, press-hardened steels as well as ultrahigh strength multiphase steels (27 % in two-seater/24 % in fourseater) in order to fulfill passive safety requirements. These are used both in the sidewalls and to a large extent in the substructure as well, particularly on the two-seater. The bodyshell of the new smart is subdivided into the following assemblies: • Front end • Front end with firewall • Substructure including rear end structure • Left/right side wall • Roof Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service. Status: 06/2014 – Front end The front end largely consists of plastic assembly parts as well as a bolted flexural member with crashboxes made of ultrahigh strength sheet steel (for ease of replacement in event of repair). The different crashboxes are matched to the different vehicle weights: • Light two-seater • Heavy two-seater and four-seater Front end with firewall The front end structure largely consists of the front longitudinal members with integrated front integral carrier mounts, the suspension strut supports, the inner A-pillar structure including second longitudinal member plane and connecting carriers with integrated rear integral carrier mounts (for two integral carrier variants). The firewall and a crossmember which meets pedestrian protection requirements under the windshield form the boundary to the interior compartment. View of front end with firewall In the event of a collision, the loads are distributed through the front end elements, the A-pillars, the crossmember and the connecting carrier towards the rocker panels, center tunnel, roof structure and doors. Sidewall of C453 P62.00-2117-00 P63.10-5289-00 Sidewall The sidewall of the new smart has a three-piece structure across almost its entire length. This consists of an inner sidewall, a reinforcing frame and a one-piece panel. To provide optimal protection in the event of a collision and maintain the integrity of the tridion safety cell, the reinforcement frame largely consists of high strength and ultrahigh strength steels.

Status: 06/2014 – 105 Body Bodyshell Body Bodyshell Substructure Instead of using two parallel longitudinal members, the substructure in the area of the main floor is formed from a center tunnel designed as a closed section. The reason for this was to take into account the powerplant variant with electric motor and the resulting requirement to accommodate the batteries. Roof The following roof variants are possible depending on the vehicle variant. Roof variants of C453 • Fixed roof with sandwich design • Transparent panoramic roof made of polycarbonate with fabric roller blind Roof variants of W453 • Roof made of sheet steel • Panoramic glass roof with fabric roller blind • Electric folding/sliding roof (fabric) P61.00-2059-00 View of substructure 106 Introduction of the New smart fortwo coupé and smart forfour | Model Series 453 – This printout will not be recorded by the update service.
