board, for example. Your feet may otherwisebe in the deployment area of the air bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint sys-tems. Up to this height, the seat belt cannotbe worn correctly.
If a child is traveling in your vehicle, alsoobserve the following notes:
RAlways secure children under twelve years ofage and less than 5 ft (1.50m)tall in suitablechild restraint systems.
RChild restraint systems should be installed onthe rear seats.
ROnly secure a child in a rearward-facing childrestraint system on the front-passenger seatwhen the front-passenger front air bag isdeactivated. If the PASSENGER AIR BAG OFFindicator lamp is permanently lit, the front-passenger front air bag is deactivated(Ypage 44).
RAlways observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Ypage 51) and on "Children in thevehicle" (Ypage 59) in addition to the childrestraint system manufacturer's installationand operating instructions.
Objects in the vehicle interior may preventan air bag from functioning correctly.Beforestarting your journey and to avoid risks resultingfrom the speed of the air bag as it deploys, makesure 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
Rthere are no hard objects, e.g. coat hangers,hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, areattached to the vehicle within the deploymentarea of an air bag, e.g. to doors, side windows,rear side trim or side walls
Rno heavy, sharp-edged or fragile objects are inthe pockets of your clothing. Store suchobjects in a suitable place
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover 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 pan-
eling carried out at a qualified specialist work-
shop.
Front air bags
!Do not place heavy objects on the front-passenger seat. This could cause the systemto identify the seat as being occupied. In theevent of an accident, the restraint systems onthe front-passenger side may be triggeredand have to be replaced.
Driver's air bagCdeploys in front of the steer-ing wheel. Front-passenger front air bagDdeploys in front of and above the glove box.
When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the front seats.
The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Ypage 44).

The front-passenger front air bag will onlydeploy if:
Rthe system, based on the OCS weight sensorreadings, detects that the front-passengerseat is occupied (Ypage 51). ThePASSENGER AIR BAG OFF indicator lamp isnot lit (Ypage 51)
Rthe restraint system control unit predicts ahigh accident severity
Driver's knee bag
Driver's knee bagCdeploys under the steeringcolumn. The driver's knee bag is deployedtogether with the front air bag.
The driver's knee bag offers additional thigh,knee and lower leg protection for the occupantin the driver's seat.
Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. In addition, the operation of
the occupant classification system (OCS)
could be adversely affected. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bagsCand rear sideimpact air bagsDdeploy next to the outer bol-ster of the seat backrest.
When deployed, the side impact air bag offersadditional thorax protection. However, it doesnot protect the:
Rhead
Rneck
Rarms
If the restraint system control unit detects a sideimpact, the side impact air bag is deployed onthe side on which the impact occurs.
The side impact air bag on the front passengerside deploys under the following conditions:
Rthe OCS system detects that the frontpassenger seat is occupied or
Rthe seat belt buckle tongue is engaged in thebelt buckle of the front passenger seat
If the belt tongue is engaged in the belt buckle,the side impact air bag on the front passengerside deploys if an appropriate accident situationoccurs. In this case, deployment is independentof whether the front passenger seat is occupiedor not.

they provide an indication of air bag deploy-ment.
The vehicle can be deformed considerably, with-out an air bag being deployed. This is the case ifonly parts which are relatively easily deformedare affected and the rate of deceleration is nothigh. Conversely, air bags may be deployed eventhough the vehicle suffers only minor deforma-tion. This is the case if, for example, very rigidvehicle parts such as longitudinal body mem-bers are hit, and sufficient deceleration occursas a result.
If the restraint system control unit detects a sideimpact or if the vehicle rolls over, the applicablecomponents of the restraint system aredeployed independently of each other depend-ing on the apparent type of accident.

PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE®
takes pre-emptive measures to protect the vehi-cle occupants.
Important safety notes
!Make sure that there are no objects in thefootwell or behind the seats. There is a dangerthat the seats and/or objects could be dam-
aged when PRE-SAFE®is activated.
Despite your vehicle being equipped with the
PRE-SAFE®system, the possibility of personalinjuries occurring as a result of an accident can-not be eliminated. Always adapt your drivingstyle to suit the prevailing road and weatherconditions and maintain a safe distance fromthe vehicle in front. Drive carefully.
Function
PRE-SAFE®intervenes:
Rin emergency braking situations, e.g. whenBAS is activated
Rin critical driving situations, e.g. when physi-cal limits are exceeded and the vehicle under-steers or oversteers severely
Rvehicles with the Driving Assistance package:when a driver assistance system intervenespowerfully or the radar sensor system detectsan imminent danger of collision in certain sit-uations
Occupant safety57
Safety
Z

PRE-SAFE®takes the following measuresdepending on the hazardous situation detected:
Rthe front seat belts are pre-tensioned.
Rif the vehicle skids, the side windows and thesliding sunroof are closed.
Rvehicles with the memory function for thefront-passenger seat: the front-passengerseat is adjusted if it is in an unfavorable posi-tion.
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE®slackens the belt
pre-tensioning. All settings made by PRE-SAFE®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
XMove the seat backrest or seat back slightlywhen the vehicle is stationary.The seat belt pre-tensioning is reduced andthe locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. Informa-tion about the convenience function can befound under "Belt adjustment" (Ypage 47).
PRE-SAFE®PLUS (anticipatory occu-
pant protection system PLUS)
Introduction
PRE-SAFE®PLUS is only available in vehicleswith the Driving Assistance package.
Using the radar sensor system, PRE-SAFE®
PLUS is able to detect that a frontal or rear-endcollision is imminent. In certain hazardous sit-
uations, PRE-SAFE®PLUS takes pre-emptivemeasures to protect the vehicle occupants.
Important safety notes
The intervention of PRE-SAFE®PLUS cannotprevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE®PLUS.
PRE-SAFE®PLUS does not intervene:
Rif the vehicle is backing up
Rwhen the vehicle is towing a trailer and thereis a risk of a rear-end collision
When driving, or when parking or exiting a park-ing space using Active Parking Assist, PRE-
SAFE®PLUS will not apply the brakes.
Function
PRE-SAFE®PLUS intervenes in certain situa-tions if the radar sensor system detects animminent frontal or rear-end collision.
PRE-SAFE®PLUS takes the following measuresdepending on the hazardous situation detected:
Rif the radar sensor system detects that ahead-on collision is imminent, the seat beltsare pre-tensioned.
Rif the radar sensor system detects that a rear-end collision is imminent:
-the brake pressure is increased if the driverapplies the brakes when the vehicle is sta-tionary.
-the seat belts are pre-tensioned.
The PRE-SAFE®PLUS braking application is can-celed:
Rif the accelerator pedal is depressed when agear is engaged
Rif the risk of a collision passes or is no longerdetected
Rif Active Distance Assist DISTRONIC indicatesan intention to intervene
If the hazardous situation passes without result-ing in an accident, the original settings arerestored.
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the electri-cally adjustable steering wheel is raised whenthe driver's door is opened
Rthe engine is switched off and the fuel supplyis cut off
Rvehicles with mbrace: automatic emergencycall

BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.If you depress the brake pedal quickly, BASautomatically boosts the braking force, thusshortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
GWARNING
If BAS is malfunctioning, the braking distance
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 65).
Active Brake Assist consists of a distance warn-ing function with an autonomous braking func-tion and Adaptive Brake Assist.
Active Brake Assist can help you to minimize therisk of a collision with the vehicle traveling infront or reduce the effects of such a collision.
If Active Brake Assist detects that there is a riskof collision, you will be warned visually andacoustically. If you do not react to the visual andaudible collision warning, autonomous brakingcan be initiated in critical situations. If you applythe brake yourself in a critical situation, Adap-tive Brake Assist of the Active Brake Assist sys-tem 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 different line
RYou are driving a new vehicle or servicing onthe Active Brake Assist system has just beencarried out
Observe the important safety notes in the"Breaking-in notes" section (Ypage 130).
Following damage to the front end of the vehicle,have the configuration and operation of theradar sensor checked at a qualified specialistworkshop. This also applies to collisions at slowspeeds where there is no visible damage to thefront of the vehicle.
Activating/deactivating
Active Brake Assist is automatically active afterswitching on the ignition.
You can activate or deactivate Active BrakeAssist (Ypage 220) in the on-board computer.When deactivated, the distance warning func-tion and the autonomous braking function arealso deactivated.
If Active Brake Assist is deactivated, the

reacting to moving objects that have alreadybeen detected as such at least once over theperiod of observation.
Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts to sta-tionary obstacles.
If adaptive Brake Assist demands particularlyhigh braking force, preventative passenger pro-
tection measures (PRE-SAFE®) are activatedsimultaneously (Ypage 57).
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 vehicle
Adaptive Brake Assist is then deactivated.
Important safety notes
iObserve the "Important safety notes" sec-tion for driving safety systems (Ypage 65).
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 sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
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 sit-
uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Brake Assist to intervene.
If adaptive Brake Assist is not available due to amalfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
ESP®monitors driving stability and traction, i.e.power transmission between the tires and theroad surface.
If ESP®detects that the vehicle is deviating fromthe direction desired by the driver, one or morewheels are braked to stabilize the vehicle. Theengine output is also modified to keep the vehi-cle on the desired course within physical limits.
ESP®assists the driver when pulling away on
wet or slippery roads. ESP®can also stabilizethe vehicle during braking.
4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-tion (Ypage 65).
ETS traction control is part of ESP®. On vehicles
with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pullaway and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is transfer-red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP®.
