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 26). Panic alarm

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. Furthermore, the restraint system
can also reduce the forces to which vehicle
occupants are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system
The various components of the restraint sys-
tem work complementary to one another. It
can only provide maximum protection if all
vehicle occupants:
R have their seat belt correctly fastened
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 105).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 104).
Additionally, you must ensure that an airbag
can deploy freely (Y page 48).
An airbag is supplementary to a correctly fas- tened seatbelt and, as an additional safety
device, provides greater protection for vehi-
cle occupants in an accident situation. If the
protection provided by the seat belt is suffi-
cient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given acci-
dent situation deploy. However, seat belts
and airbags generally do not protect against
objects penetrating the vehicle from the out- side.
Information on how the restraint system
operates can be found in "Deployment of the
seat belt tensioner and airbags"
(Y page 51). 42
Occupant safetySafety

WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec-
essary, adjust the vehicle belt sash guide and the front-passenger seat accordingly. Always
observe the information about suitable posi-
tioning of the child restraint system in this
Owner's Manual as well as the child restraint system manufacturer's installation instruc-
tions.
i Ensure that your vehicle is equipped with
automatic child seat recognition for the
front-passenger seat (Y page 61). If this
is not the case, always fit the child restraint
system on a suitable rear seat
(Y page 63). 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 press the Start/Stop button once
or twice on vehicles with KEYLESS-GO.
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 is lit, the front-passenger front airbag is
disabled. They 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 thefront-passenger front airbag both before and
during the journey. 60
Children in the vehicleSafety

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
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 54). If a risk of collision remains at
speeds over 30 km/h and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided. Anti-theft systems

General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY- LESS-GO key in the vehicle.
Locking and unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the key with you. You can combine the KEY-
LESS-GO functions with the functions of a
conventional key. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using
the & button on the key.
When locking or unlocking with KEYLESS-GO,
the distance between the key and the corre-
sponding door handle must not be greater
than 1 m.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example:
R when the external door handles are
touched
R when starting the engine
R while the vehicle is in motion Key
