Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Panic alarm

again.
or
X Insert the key into the ignition lock.
or X Press the KEYLESS-GO Start/Stop button.
The KEYLESS-GO key must be in the vehi-
cle.
i The panic alarm function is only available
in certain countries. Occupant safety
Introduction to the restraint system
The restraint system reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes the:
R seat belt system
R airbags
The components of the restraint system work
in conjunction with each other. They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 43)
R have the seat and head restraint adjusted
properly (Y page 97)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observe the information on the correct driv-
er's seat position (Y page 96).
In addition, you must make sure that the air-
bags can inflate properly if they are deployed (Y page 45).
An airbag supplements a correctly worn seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The
airbags are not deployed, for example, in the event of an accident in which sufficient pro-
tection is offered by the seat belt. In addition,
only those airbags, which in the applicable
accident situations offer additional protec-
tion, are deployed in the event of an accident.
However, the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deployment of
belt tensioners and airbags" (Y page 47).
See "Children in the vehicle" for further infor- mation on children travelling in the vehicle as 40

PASSENGER AIR BAG OFF indicator lamp
:
shows you whether the front-passenger front airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or on vehicles with KEYLESS-GO, press
the Start/Stop button once or twice.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up , the front-passenger front airbag
is disabled. It will then not be deployed in
the event of an accident.
R is not lit, the sensor system did not detect
a child restraint system with transponder
for automatic child seat recognition. If, in
the case of an accident, all deployment cri-
teria are met, the front-passenger front air-
bag is deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger front airbag both before and
during the journey. Child restraint system on the front-
passenger seat
General notes If you secure a child in a child restraint system
on the front-passenger seat, always observe
the information on "Automatic child seat rec-
ognition on the front-passenger seat"
(Y page 52).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic child seat recognition
sensor system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion.
G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child
could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR-BAG OFF indicator lamp must be lit. 54
Children in the vehicleSafety

If there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE ®
) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto- matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
You can prevent the intervention of PRE-
SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer any danger of a collision
R there is no longer an obstacle detected in
front of your vehicle Protection against theft
