Before commencing your journey, ensure that:
Rthere are no people, animals or objectsbetween the vehicle occupants and an air-bag
Rthere are no objects between the seat, doorand B-pillar
Rno accessories, such as cup holders, areattached to the vehicle within the deploy-ment area of an airbag, e.g. to doors or sidewindows
Rno heavy, sharp-edged or fragile objects arein the pockets of your clothing. Store suchobjects in a suitable place
GWARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
GWARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or
door paneling carried out at a qualified spe-
cialist workshop.
Front air bags
!Do not place heavy objects on the front-passenger seat. This could cause the sys-tem to identify the seat as being occupied.In the event of an accident, the restraintsystems on the front-passenger side may betriggered and have to be replaced.
Driver's air bagCdeploys in front of thesteering wheel. Front-passenger front airbagDdeploys in front of and above the glovebox.
When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the driver's and front-passengerseats.
The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Ypage 39).
The front-passenger front air bag will onlydeploy if:
Rthe system, based on the OCS weight sen-sor readings, detects that the front-passenger seat is occupied (Ypage 46).The PASSENGER AIR BAG OFF indicatorlamp is not lit (Ypage 46)
Rthe restraint system control unit predicts ahigh accident severity
Knee bags
Driver's knee bagCdeploys under the steer-ing column and front-passenger knee bagDunder the glove box. The driver's and front-passenger knee bags are triggered togetherwith the front air bags.

Safety

GWARNING
If BAS is malfunctioning, the braking dis-
tance in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed untilthe emergency braking situation is over.ABS prevents the wheels from locking.
The brakes will function as usual once yourelease the brake pedal. BAS is deactivated.
Active Brake Assist
General information
iObserve the "Important safety notes" sec-tion (Ypage 57).
Active Brake Assist consists of a distancewarning function with an autonomous brakingfunction and Adaptive Brake Assist.
Active Brake Assist can help you to minimizethe risk of a collision with the vehicle in frontor reduce the effects of such a collision.
If Active Brake Assist detects that there is arisk of collision, you will be warned visuallyand acoustically. If you do not react to the vis-ual collision warning or the warning tone,autonomous braking can be initiated in criticalsituations. If you apply the brake yourself in acritical situation, Adaptive Brake Assist of theActive Brake Assist system supports you.
Important safety notes
In particular, the detection of obstacles can beimpaired if:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-ple in parking garages
Ra narrow vehicle is traveling in front, e.g. amotorbike
Ra vehicle is traveling in front on a differentline
Ryou are driving a new vehicle or servicing onthe Active Brake Assist system has justbeen carried out
Observe the important safety notes in the"Breaking-in notes" section (Ypage 117).
Following damage to the front end of the vehi-cle, have the configuration and operation ofthe radar sensor checked at a qualified spe-cialist workshop. This also applies to collisionsat slow speeds where there is no visible dam-age to the front of the vehicle.
Activating/deactivating
Active Brake Assist is automatically activeafter switching on the ignition.
You can activate or deactivate Active BrakeAssist using the on-board computer(Ypage 175). When deactivated, the distancewarning function and the autonomous brakingfunction are also deactivated.
If Active Brake Assist is deactivated, the

4 mph (7 km/h). It uses radar sensor technol-ogy to assess the traffic situation.
Up to a speed of approximately 155 mph(250 km/h), Adaptive Brake Assist is capableof reacting to moving objects that havealready been detected as such at least onceover the period of observation.
Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts tostationary obstacles.
If Adaptive Brake Assist demands particularlyhigh braking force, preventative passenger
protection measures (PRE-SAFE®) are activa-ted simultaneously (Ypage 53).
XKeep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.
The brakes will work normally again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehi-cle
Adaptive Brake Assist is then deactivated.
Important safety notes
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate
the intervention in a non-critical driving sit-
uation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, the Adaptive Brake Assist may
not intervene in all critical conditions. There
is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Always adapt your speed to suit the prevail-
ing road and traffic conditions.
Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Adaptive Brake Assist to inter-vene.
If Adaptive Brake Assist is not available due toa malfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.
Adaptive brake lights
iObserve the "Important safety notes" sec-tion (Ypage 57).
If you brake sharply from a speed of more than50 km/h or if braking is assisted by BAS orBrake Assist with Cross-Traffic Assist, thebrake lamps flash rapidly. In this way, traffictraveling behind you is warned in an evenmore noticeable manner.
If you brake sharply from a speed of more than70 km/h to a standstill, the hazard warninglamps are activated automatically. If thebrakes are applied again, the brake lamps lightup continuously. The hazard warning lampsswitch off automatically if you travel fasterthan 10 km/h. You can also switch off thehazard warning lamps using the hazard warn-ing button (Ypage 99).
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 57).
ESP®monitors driving stability and traction,i.e. power transmission between the tires andthe road surface.
If ESP®detects that the vehicle is deviatingfrom the direction desired by the driver, one ormore wheels are braked to stabilize the vehi-cle. The engine output is also modified to keep

Locking/unlocking centrally
You can start, lock or unlock the vehicle usingKEYLESS-GO. To do this, you only need carrythe SmartKey with you. You can combine thefunctions of KEYLESS-GO with those of a con-ventional SmartKey. Unlock the vehicle byusing KEYLESS-GO, for instance, and lock itusing the7button on the SmartKey.
The driver's door and the door at which thehandle is used, must both be closed. TheSmartKey must be outside the vehicle. Whenlocking or unlocking with KEYLESS-GO, thedistance between the key and the correspond-ing door handle must not be greater than 3 ft(1 m).
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen the external door handles are touched
XTo unlock the vehicle:touch the inner sur-face of the door handle.
XTo lock the vehicle:touch sensor sur-faceCorD.
Make sure that you do not touch the innersurface of the door handle.
XConvenience closing feature:touchrecessed sensor surfaceDfor an extendedperiod.
Further information on the convenienceclosing feature (Ypage 77).
Deactivating and activating
If you do not intend to use a SmartKey for anextended period of time, you can deactivatethe KEYLESS-GO function of the key. The
SmartKey will then use very little power,thereby conserving battery power. For the pur-poses of activation/deactivation, the vehiclemust not be nearby.
XTo deactivate:press the7button onthe SmartKey twice in rapid succession.The battery check lamp (Ypage 69) of theSmartKey flashes twice briefly and lights uponce, then KEYLESS-GO is deactivated.
XTo activate:press any button on the Smart-Key.
or
XInsert the SmartKey into the ignition lock.KEYLESS-GO and all of its associated fea-tures are available again.
Changing the settings of the locking
system
You can change the settings of the lockingsystem. This means only the driver's door, thelockable stowage compartments in the vehicleinterior and the fuel filler flap are unlockedwhen the vehicle is unlocked. This is useful ifyou frequently travel alone.
XTo change the setting:press and holddown the6and7buttons simultane-ously for about six seconds until the batteryindicator lamp (Ypage 69) flashes twice.
If the setting of the locking system is changedwithin the signal range of the vehicle, pressingthe7or6button:
Rlocks or
Runlocks the vehicle
The SmartKey now functions as follows:
XTo unlock:press the6button once.
XTo unlock centrally:press the6buttontwice.
XTo lock centrally:press the7button.
The KEYLESS-GO function is changed as fol-lows:
XTo unlock the driver's door:touch theinner surface of the door handle on the driv-er's door.
XTo unlock centrally:touch the inner sur-face of the driver or front-passenger doorhandle.
