Introduction to the restraint system
The restraint system can reduce 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 system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 100).
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 100).
Additionally, you must ensure that an airbag can
deploy freely (Y page 48).
The airbag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given accident situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 56).
See "Children in the vehicle" for information on
infants and children traveling with you in the
vehicle restraint systems for infants and chil-
dren(Y page 59). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If the vehicle needs to be adapted to accommo- date a person with disabilities, please contact a
specialist workshop. 42
Occupant safetySafety

If such objects are located on or in your cloth-
ing, e.g. pens, keys, spectacles, etc. stow
these in a suitable location.
R Only one person should use each seat belt at
any one time.
Babies and children must never travel sitting
on the lap of another vehicle occupant. In the event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R Do not secure any objects with a seat belt if
the seat belt is being used by one of the vehi- cle's occupants.
You must also make sure that objects, e.g.
cushions, are never placed between a person
and the seat.
Seat belts are solely intended to secure and
restrain persons. To secure objects, luggage or
loads, always observe the "Loading guidelines"
(Y page 296).
Fastening the seat belts Observe the safety notes on the seat belt
(Y
page 44) and the information on the correct
use of the seat belt (Y page 45).G
WARNING
If the seat-belt extender extends during the
journey, the seat belt is not sitting correctly
across your body. The seat belt then cannot
perform its intended protective function.
There is an increased risk of injury, possibly
even fatal.
During a journey, make sure that the seat-belt extender is retracted.
If the seat-belt extender does not retract auto-
matically, you can return it manually. Press the
seat-belt extender back to the stop before start-
ing the vehicle to do so. Returning the seat-belt
extender requires force. The seat-belt extender for the driver and front
passenger helps you fasten your seat belt. Seat- belt extender =is extended when the respec-
tive door is closed. You can also extend seat-belt extender

front-passenger seat. The child restraint system
must not touch the roof or be put under strain bythe head restraint. Adjust the angle of the seat
backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system (Y page 62) in addition to the
child restraint system manufacturer's installa-
tion instructions.
Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the
event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears on the instrument
cluster (Y page 251). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front
airbag both before and during the journey.
If a person sits in the passenger seat, he/she
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with his/her
back against the seat backrest
R with his/her feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers his/her weight by supporting him-
self/herself on a vehicle armrest
R sits in such a way that his/her weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag then does not
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially 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 make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa- Occupant safety
