Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk ofvehicle occupants coming into contact withparts of the vehicle's interior in the event of anaccident. The restraint system can also reducethe forces to which vehicle occupants are sub-jected during an accident.
The restraint system includes the followingcomponents:
Rseat belt system
Rair bags
The components of the restraint system workin conjunction with each other. They can onlydeploy their protective function if, at all times,all vehicle occupants:
Rhave fastened their seat belts correctly(Ypage 41)
Rhave the seat and head restraint adjustedproperly (Ypage 85)
As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.
Observe the information relating to the correctdriver's seat position (Ypage 85).
You also have to make sure that an air bag caninflate properly if deployed (Ypage 43).
An air bag supplements a correctly worn seatbelt. As an additional safety device, the air bagincreases the level of protection for vehicleoccupants in the event of an accident. Forexample, if, in the event of an accident, theprotection offered by the seat belt is sufficient,the air bags are not deployed. When an acci-dent occurs, only the air bags that increaseprotection in that particular accident situationare deployed. However, seat belts and air bagsgenerally do not protect against objects pene-trating the vehicle from the outside.
Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags"(Ypage 50).
See "Children in the vehicle" for informationon children traveling with you in the vehicle aswell as on child restraint systems(Ypage 53).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in
an accident or trigger unexpectedly, for
example. This poses an increased risk of
injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of therestraint system to accommodate a personwith disabilities, contact an authorizedMercedes-Benz Center for details. USA only:for further information contact our CustomerAssistance Center at 1-800 FOR-MERCEDES(1‑800‑367‑6372).
Mercedes-Benz recommends that you only usedriving aids which have been approved specifi-cally for your vehicle by Mercedes-Benz.

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe headbag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If you install a child restraint system on thefront-passenger seat, be sure to observe thecorrect positioning of the child restraint sys-tem. Never place objects under or behind thechild restraint system, e.g. a cushion. Theentire base of the child restraint system mustalways rest on the seat cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat aspossible against the backrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.

DPASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether thefront-passenger front air bag is deactivated orenabled.
XPress the Start/Stop button once or twice,or turn the SmartKey to positionGorHinthe ignition lock.The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps mustlight up simultaneously for approximately sixseconds.
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for60 seconds, subsequently both indicatorlamps are off (PASSENGER AIR BAG ON andOFF): the front-passenger front air bag isable to deploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag display message appears in the instru-ment cluster (Ypage 191). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG OFF indicatorlamp. Be aware of the status of the front-

iObserve the "Important safety notes" sec-tion (Ypage 57).
ADAPTIVE BRAKE enhances braking safety andoffers increased braking comfort. In additionto the braking function, ADAPTIVE BRAKE alsohas the HOLD function (Ypage 151) and hillstart assist (Ypage 120).
Protection against theft
Immobilizer
XTo activate with the SmartKey:removethe SmartKey from the ignition lock.
XTo activate with KEYLESS-GO:switch theignition off and open the driver's door.

When you close the driver's door with the igni-tion switched on, the steering wheel is alsoautomatically moved to the previously setposition.
The last position of the steering column isstored when you switch off the ignition orwhen you store the setting with the memoryfunction (Ypage 95).
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature istriggered in an accident, the steering columnwill move upwards when the driver's door isopened. This occurs irrespective of the posi-tion of the SmartKey in the ignition lock. Thismakes it easier to exit the vehicle and rescuethe occupants.
The crash-responsive EASY-EXIT feature is onlyoperational if the EASY-EXIT/ENTRY feature isactivated in the on-board computer(Ypage 178).

GWARNING
You could lose control of your vehicle if you
do the following while driving:
Radjust the driver's seat, head restraint,

Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint,
steering wheel and mirror and fasten your
seat belt before starting the engine.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an
accident.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.
