• Depress the brake pedal. The gear selector lever lock is released.

Starting with KEYLESS-GO

You can start your vehicle without the SmartKey in the starter switch using the KEYLESS-GO start/stop button on the gear selector lever. The SmartKey with KEYLESS-GO must be located in the vehicle.

• Make sure the gear selector lever is set to P.
• Depress the brake pedal during the starting procedure. Do not depress accelerator.
• Press KEYLESS-GO start/stop button (1) once. The engine starts automatically if the SmartKey with KEYLESS-GO is in the vehicle.

Starting difficulties If the engine does not start as described, carry out the following steps:

• If you are starting the engine with the SmartKey, turn SmartKey in starter switch to position 0 and repeat starting procedure.
• If you are starting the engine with KEYLESS-GO: Close any doors that may be open to allow for better detection of the SmartKey with KEYLESS-GO or start the engine with the SmartKey as radio signals from another source may be interfering with the SmartKey with KEYLESS-GO.

After exiting the vehicle, press lock button 1 on the door handle or on the trunk lid. All turn signal lamps flash three times. The locking knobs on the doors move down.

Occupant safety

In this section you will learn the most important facts about the restraint systems of the vehicle. The restraint systems are:

• Seat belts
• Emergency tensioning device
• Airbags
• Child seats
• Child seat recognition
• Lower anchors and tethers for children (LATCH)

As independent systems, their protective effects work in conjunction with each other.

The SRS indicator lamp in the instrument cluster comes on

• for about four seconds when you turn the SmartKey in the starter switch to position 1 or press the KEYLESS-GO start/stop button once. It then goes out briefly, comes on again and remains lit until you start the engine.
• for about four seconds when you start the engine by turning the SmartKey or pressing the KEYLESS-GO start/stop button.
• The SRS indicator lamp remains lit if the SmartKey is turned to position 2 and left there or the KEYLESS-GO start/stop button is pressed twice. The

indicator lamp will go out when you start the engine.

The restraint systems are fully operational if the SRS indicator lamp is not lit when the engine is running. A malfunction in the system has been detected if the SRS indicator lamp:

• fails to extinguish after approximately four seconds.
• does not come on at all.
• comes on after the engine was started or while driving.

In the event that the SRS indicator lamp comes on during driving or does not come on at all, the SRS self-check has detected a malfunction. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the SRS may not be activated when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unnecessarily which could also result in injury.

Airbags are designed to reduce the potential of injury and fatality in certain frontal impacts (front airbags), side impacts (side impact airbags and head protection window curtain airbags) or rollovers (head protection window curtain airbags). However, no system available today can totally eliminate injuries and fatalities. The activation of the airbags temporarily releases a small amount of dust from the airbags. This dust, however, is neither injurious to your health, nor does it indicate a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so. If you have any breathing difficulty but cannot get out of the vehicle after the airbag inflates, then get fresh air by opening a window or door.

For maximum protection in the event of a collision always be in normal seated position with your back against the seat backrest. Fasten your seat belt and ensure that it is properly positioned on your body. Since the airbag inflates with considerable speed and force, a proper seating and hands on steering wheel position will help to keep you at a safe distance from the airbag. Occupants who are unbelted, out of position or too close to the airbag can be seriously injured by an airbag as it inflates with great force in the blink of an eye:

• Sit properly belted in a nearly upright position with your back against the seat backrest.
• Adjust the driver seat as far as possible

rearward, still permitting proper operation of vehicle controls. The distance from the center of the driver’s breastbone to the center of the airbag cover on the steering wheel must be at least 10 in (25 cm) or more. You should be able to accomplish this by a combination of adjustments to the seat and steering wheel.

• Do not lean with your head or chest close to the steering wheel or dashboard.
• Keep hands on the outside of steering wheel rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when driver front airbag inflates.
• Adjust the front passenger seat as far as possible rearward from the dashboard when the seat is occupied.
• Occupants, especially children, should never lean their heads in the area of the door where the side airbag inflates.

This could result in serious injuries or death should the airbag be triggered. Always sit nearly upright, properly use the seat belts and appropriate size infant or child restraint system.

• Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart TM compatible child seat, which operates with the BabySmart TM system installed in the vehicle to deactivate the passenger front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result.

Accident research shows that the safest place for children in an automobile is in the rear seat. Should you choose to place a child 12 years old or under in the front passenger seat of your vehicle, you must properly use a BabySmart TM child restraint which will turn off the passenger front airbag. BabySmart TM will not, however, turn off any side impact airbag.

Airbags are designed to activate only in certain frontal (front airbags) impacts, side impacts (side impact and head protection window curtain airbags) which exceed preset thresholds, and in certain rollovers (head protection window curtain airbags). Only during these events will they provide their supple- mental protection. The driver and passengers should always wear their seat belts. Otherwise it is not possible for airbags to provide their supplemental protection.

In case of other types of impacts and impacts below airbag deployment thresholds, airbags will not be activated. The driver and passengers will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also needed to provide the best possible protection in a rollover.

• Airbags and pyrotechnic emergency tensioning devices (ETDs) are designed to function on a one-time only basis. An airbag or ETD that was activated must be replaced. PRE-SAFE has electrically operated reversible pre-tensioners in addition to the pyrotechnic ETDs.
• An airbag system component within the steering wheel gets hot after the airbag has inflated. Do not touch.

Front airbags

• (1) Driver airbag
• (2) Passenger front airbag

Driver and passenger front airbags are deployed:

• in the event of a frontal impact
• if impact exceeds a preset deployment threshold
• independently of the side impact airbags

The airbags will not deploy in impacts which do not exceed the system’s deployment thresholds. You will then be protected by the fastened seat belts.

The passenger front airbag will only be deployed if:

• the front passenger seat is occupied
• the PASSENGER AIRBAG OFF indicator lamp in the center console is not lit
• the impact exceeds a preset deployment threshold

Do not place objects heavier than 20 lbs (9 kg) on the front passenger seat. This could cause the front or side impact airbag on the front passenger side to deploy in a crash which exceeds the system's deployment threshold.

Side impact airbags, window curtain airbags

• (1) Window curtain airbag
• (2) Side impact airbags

The side impact airbags and window curtain airbags are deployed:

• on the impacted side of the vehicle
• in impacts exceeding a preset deployment threshold
• independently of the front airbags

In addition, the window curtain airbags are deployed:

• in certain vehicle rollovers

The side impact airbags and window curtain airbags are not deployed in impacts which do not exceed the system’s deployment threshold. The front passenger side impact airbag will only deploy if the system senses that the front passenger seat is occupied.

Emergency tensioning device (ETD), seat belt force limiter The seat belts for the front and rear outer seats are equipped with emergency tensioning devices and belt force limiters.

The ETD is designed to activate in the following cases:

• in frontal or rear-end impact exceeding a preset severity level
• in certain vehicle rollovers
• if the restraint systems are operational and functioning correctly (see SRS indicator lamp)

The ETDs for the front seats will only activate if the respective front seat belt is fastened (latch plate properly inserted into buckle). The ETDs for the rear outer seats will activate with or without the respective seat belt fastened.

In an impact, emergency tensioning devices remove slack from the belts in such a way that the seat belts fit more snugly against the body. Belt force limiters reduce the force exerted by the seat belts on occupants during a crash.

A pyrotechnic emergency tensioning device (ETD) that was activated must be replaced.

PRE-SAFE has electrically operated reversible pre-tensioners that do not require replacement after activation.

Automatic comfort-fit feature seat belt An automatic comfort-fit feature for front seats and for the rear outer seats (only for vehicles with electrically adjustable rear bench seat or with individual seats in the rear) reduces the retracting force of the seat belts when they are in normal use.

Preventive occupant safety (PRE-SAFE) The PRE-SAFE system is intended to reduce the effects of an accident on properly seat belted vehicle occupants.

Your vehicle automatically takes preventive measures to better protect the occupants in the following hazardous situations:

• You execute an emergency braking maneuver and the Brake Assist System is activated.
• The PRE-SAFE system detects a critical driving dynamics situation.

The PRE-SAFE systems are activated in the previously described circumstances only at speeds exceeding 22 mph (35 km/h).

In such cases, the following systems are automatically activated:

• A front seat belt with the seat belt buckled is pre-tensioned electrically.
• If the occupied front passenger seat or rear seats are in an unfavorable position,

they are adjusted to a better position. Rear seat adjustment occurs only in vehicles with individual seats in the rear.

• The sliding/pop-up roof closes if the vehicle is in a severe skid or is spinning.

When the driving dynamic situation has passed without an accident occurring, the pre-tensioning on the seat belts is deactivated. You can then adjust the seats and the sliding sunroof to their previous position.

If the seat belts do not release: Adjust the backrest or seat slightly to the rear until the seat belt tension is diminished. The locking mechanism releases.

Seat belts When the engine is started, the seat belt telltale illuminates to remind you and your passengers to fasten your seat belts. If the driver’s seat belt is not fastened before the engine is started, the seat belt telltale illuminates and a warning chime sounds for approximately six seconds when the engine is started.

Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a nearly upright position and the belt is properly positioned on the body.

Occupant safety

Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart TM compatible child seat, which operates with the BabySmart TM system installed in the vehicle to deactivate the passenger front airbag when it is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating positions. Infants and small children must ride in back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle's seat belt and top tether strap, or secured via lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions.

Children too big for child restraint systems must ride in back seats using regular seat belts. A booster seat may be necessary to achieve proper belt positioning for children from 41 lbs until they reach a height where a lap/shoulder belt fits properly without a booster.

BabySmart TM1 airbag deactivation system

Special BabySmart TM compatible child seats, designed for use with the Mercedes-Benz system and available at any authorized Mercedes-Benz Center are required for use with the BabySmart TM airbag deactivation system. With the special child seat properly installed, the passenger front airbag will not deploy. Note, that the system does not deactivate the side impact airbag or the emergency tensioning device. BabySmart TM is a trademark of Siemens Automotive Corp.

Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the deactivation system. The bottom of the child seat must make full contact with the passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of protecting the child.

If the child seat is installed the "PASSENGER AIRBAG OFF" indicator lamp (1) located in the center console will be illuminated, except with the SmartKey removed or in starter switch position 0.

Self-test BabySmart TM without special child seat installed: After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO start/stop button once or twice, the PASSENGER AIRBAG OFF indicator lamp (1) located in the center console comes on for approximately six seconds and then goes out.

If the indicator lamp should not come on or is continuously lit, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat.

Make sure to check the indicator every time you use the special system child seat. Should the light go out while the restraint is installed, please check installation. If the light remains out, do not use the BabySmart TM restraint to transport children on the front passenger seat until the system has been repaired. Do not place powered-on laptops, cell phones and like electronic devices on the front passenger seat. Signals from such devices may interfere with the BabySmart TM system. Such signal interference may cause the PASSENGER AIRBAG OFF indicator lamp not to come on during self-test or be continuously lit, indicating that the system is not functioning.

Installation of infant and child restraint systems

This vehicle is equipped with tether anchorages for a top tether strap at each of the rear seating positions.

• (1) Cover of top anchorage ring

• Remove cover (1) from anchorage ring.
• Store cover (1) in a convenient place (e.g. glove box).
• Guide tether strap between head restraint and top of seat back.

Head restraints must be positioned such that the top tether strap can pass freely between the head restraint and top of seat back. Make sure the tether strap is not twisted.

• (2) Hook
• (3) Anchorage ring

Securely fasten hook (2), which is part of the tether strap, to anchorage ring (3). For safety reasons, make sure the hook has attached to the ring beyond the safety catch, as illustrated.

Once the top tether anchorage hook is attached, the child restraint itself can be secured. Tighten the top tether strap according to the child restraint manufacturer’s instructions.

Child seat anchors – LATCH type

This vehicle is equipped with two LATCH (Lower Anchors and Tethers for CHildren) type anchors (at each of the rear seats) for the installation of a LATCH child seat with the matching anchor fittings. If you have not installed a child seat, the LATCH anchor fittings are covered with an upholstery blend.

• (1) Indicates the position of the anchors
• (2) Anchors
• (3) Upholstery blend
• (4) Installation device

• Move rear power seats*/bench* to the rearmost position.
• Fold upholstery blend (3) upward.
• Turn installation device 4 to a vertical position so that upholstery blend (3) does not fold down.
• Install child seat according to the manufacturer’s instructions.

A solid connection is established between the child seat and the body of the vehicle. Do not adjust rear power seat*/bench* position after installing child restraint.

The child seat must be firmly attached in the right and left side anchor fittings. Make sure the seat belt for the center seat can operate freely with a child seat installed. Non-LATCH type child seats may also be used and can be installed using the vehicle’s seat belt system.

You can disable select functions in the rear passenger compartment for added safety (for instance when you have children riding in the rear passenger compartment). You can disable the following functions in the rear passenger compartment:

• rear door window operation
• adjustment of front passenger seat from the rear
• cigarette lighter in rear

The override switch is located on the driver’s door. To activating override switch slide override switch (1) to the right. A dot becomes visible. The functions in the rear are disabled.

Operation of the rear door windows with the switches located in the driver’s door is still possible.

Panic alarm

An audible alarm and flashing exterior lamps will operate for approximately 2.5 minutes.

To activate press and hold button (1) for at least one second. To deactivate press button 1 again or insert SmartKey in starter switch.

Driving safety systems

ABS

The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not lock during braking. This allows you to maintain the ability to steer your vehicle. The ABS is functional above a speed of approximately 5 mph (8 km/h) independent of road surface conditions. On slippery road surfaces, the ABS will respond even with light brake pressure.

The ABS indicator lamp in the instrument cluster comes on when you turn the SmartKey in the starter switch to position 2 or press the KEYLESS-GO start/stop button twice. It goes out when the engine is running.

Braking

At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the ABS is in the regulating mode. Keep firm and steady pressure on the brake pedal while experiencing the pulsation. Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.

In emergency brake maneuver Keep continuous full pressure on the brake pedal.

BAS

The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby potentially reducing the braking distance. Apply continuous full braking pressure until the emergency braking situation is over. The ABS will prevent the wheels from locking. When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated.

ESP

The Electronic Stability Program (ESP) monitors the vehicle's traction (force of adhesive friction between the tires and the road surface) and handling. The ESP recognizes when a wheel is spinning or if the vehicle starts to skid. By applying brakes to the appropriate wheel and by limiting engine output, the ESP works to stabilize the vehicle. The ESP is especially useful while driving off and on wet or slippery road surfaces. The ESP warning lamp in the instrument cluster flashes when the ESP is engaged. The ESP warning lamp in the instrument cluster comes on when you turn the SmartKey in the starter switch to position 2 or press the KEYLESS-GO start/stop button twice. It goes out when the engine is running.

Never switch off the ESP when you see the ESP warning lamp flashing in the instrument cluster. In this case proceed as follows:

• While driving off, apply as little throttle as possible.
• While driving, ease up on the accelerator.
• Adapt your speed and driving style to the prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The ESP cannot prevent accidents resulting from excessive speed.

Distronic is switched off when ESP is activated. Distronic cannot be activated when the ESP has been deactivated.

Vehicles without 4MATIC: Because of the ESP’s automatic operation, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button* in position 0 or 1) when:

• the parking brake is being tested on a brake test dynamometer
• the vehicle is being towed with the front/rear axle raised

Active braking action through the ESP may otherwise seriously damage the brake system.

To improve the vehicle's traction, turn off the ESP in driving situations where it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as:

• starting out on slippery surfaces and in deep snow in conjunction with snow chains
• in sand or gravel

The switch is located on the center console. To deactivate ESP press ESP switch (1) until the ESP warning lamp in the speedometer comes on. If one or more wheels are spinning, the ESP warning lamp in the speedometer flashes, regardless of the speed. Traction control brakes a spinning wheel even when the ESP is deactivated. The ESP always operates when you are braking, even when it has been deactivated.

Avoid spinning of a drive wheel for an extended period with the ESP switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

Models with all-wheel drive only: The 4MATIC improves the vehicle’s ability to use available traction, e.g. during winter operation in mountains under snowy conditions, by applying power to all four wheels. Do not tow with one axle raised. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty. Performance testing must only be conducted on a two-axle dynamometer.

Because of the ESP’s automatic operation, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Active braking action through the ESP may otherwise seriously damage the front or rear axle brake system. Operational tests with the engine running can only be conducted on a two-axle dynamometer.

Anti-theft systems

Immobilizer

The immobilizer prevents unauthorized persons from starting your vehicle.

Activating:

• Removing the SmartKey from the starter switch activates the immobilizer
• Turning off the engine by means of the KEYLESS-GO* start/stop button on the gear selector lever activates the immobilizer.

Deactivating:

• Inserting the SmartKey in the starter switch deactivates the immobilizer.
• Starting the engine by means of the KEYLESS-GO start/stop button on the gear selector lever deactivates the immobilizer.

Anti-theft alarm system

Once the alarm system has been armed, a visual and audible alarm is triggered when someone:

• opens a door
• opens the trunk
• opens the hood

The alarm will stay on even if the activating element (a door, for example) is immediately closed. The alarm system will also be triggered when

• someone attempts to raise the vehicle
• the vehicle is opened with the mechanical key

If the alarm stays on for more than 20 seconds, an emergency call is initiated automatically by the Tele Aid system.

The alarm system is armed after locking the vehicle with the SmartKey or KEYLESS-GO. The turn signal lamps flashes three times to indicate that the alarm system is activated. The indicator lamp in the central locking switch will flash after approximately ten seconds when the alarm system is completely armed.

If the turn signal lamps does not flash three times one of the following ele- ments may not be properly closed:

• a door
• the trunk lid
• the hood

Close the respective element and lock the vehicle again.

The alarm system is disarmed when you unlock your vehicle with the SmartKey or KEYLESS-GO. The turn signal lamps flash once to indicate that the alarm system is deactivated.

To cancel the alarm insert the SmartKey in the starter switch or press the unlock or lock button on the SmartKey. With KEYLESS-GO grasp the outside door handle or press the KEYLESS-GO start/stop button.

Tow-away alarm

Once the tow-away alarm is armed, a visual and audible alarm will be triggered when someone attempts to raise the vehicle. The tow-away protection alarm is triggered, for example, if the vehicle is lifted on one side. If the alarm stays on for more than 20 seconds, an emergency call is initiated automatically by the Tele Aid system.

When you lock your vehicle, the tow-away alarm is automatically armed after about 30 seconds. When you unlock your vehicle, the tow-away protection disarms automatically.

To prevent triggering the tow-away alarm, switch off the tow-away alarm feature before towing the vehicle, or when parking on a surface subject to movement, such as a ferry or auto train. The switch is located on the center console. File:...

• (1) Indicator lamp
• (2) Tow-away alarm off switch

• Switch off the ignition and remove the SmartKey. You cannot disarm the tow-away alarm if the ignition is switched on.
• Press switch (2). The indicator lamp (1) in the button comes on briefly.
• Exit vehicle and lock your vehicle with the SmartKey or (vehicles with KEYLESS-GO) the lock button at each door handle.

The tow-away alarm remains disarmed until you lock your vehicle again.
