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
Rchild restraint system
Rchild seat securing systems
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 42)
Rhave the seat and head restraint adjustedproperly (Ypage 92)
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 92).
You also have to make sure that an air bag caninflate properly if deployed (Ypage 44).
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 51).
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.

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 213). 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-passenger front air bag both before and duringthe journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag
is disabled. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for exam-
ple, come into contact with the vehicle's
interior, especially if the person is sitting too
close to the dashboard. This poses an
increased risk of injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the
front-passenger seat is correct and the
front-passenger front air bag is enabled or
disabled in accordance with the person in
the front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR
BAG OFF indicator lamp is off, the front-
passenger front air bag can deploy in the
event of an accident. The child could be
struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT
AIRBAG in front of it; DEATH or SERIOUS
INJURY to the child can occur.
If the PASSENGER AIR BAG OFF indicator lampstays off, do not install a rearward-facing childrestraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant ClassificationSystem" (Ypage 51).
