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 42)
R have correctly adjusted their seat and head
restraint (Y page 102).
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 102).
Additionally, you must ensure that an airbag can
deploy freely (Y page 44).
The airbag is supplementary to acorrectly 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 52).
See "Children in the vehicle" for information on
infantsa nd children traveling with you in the
vehicle restraint systems for infantsa nd chil-
dren(Y page 55). Important safety notes

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 modification of an airbag system is necessary to accommodate aperson with disabilities, con-
tact aqualified specialist workshop for details. Occupant safety

Operation of automatic front-passenger
front airba gdeactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps show you whether the co-
driver's fron tairbag is disabled or enabled.
X Press the Start/Stop button onceort wice or
turn the key to position 1or 2in the ignition
lock.
The system carries out aself-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 then show the status of the
co-driver's fron tairbag.
R PASSENGER AIR BAG ON is lit: the co-driver's
fron tairbag is enabled. If, in the case of an
accident, all deployment criteria are met, the
co-driver's fron tairbag is deployed.
R PASSENGER AIR BAG OFF is lit: the co-driv-
er's fron tairbag is disabled. It will then not be
deployed in the event of an accident.
If the status of the co-driver's fron tairbag
changes while the vehicle is in motion ,anairbag
display message appears in the instrument clus-
ter (Y page 263). When the co-driver's seat is
occupied, alway spay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the co-driver's fron tairbag both before and
during the journey.
If ap erson is occupying the co-driver's seat,
they must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet restin gonthe floor, if possible If the co-driver does not observe this, the auto-
matic co-driver's fron tairbag deactivation sys-
tem may be influenced, for example if the co-
driver:
R transfers their weight by supportin gthem-
selves on avehicle armrest
R sits in such away that their weight is raised
from the seat cushion
This or similar behaviour can cause the co-driv-
er's fron tairbag to be deactivated when it
should not be. In this case, PASSENGER AIR BAG OFF indicator lamp lights up continuously. The
co-driver's fron tairbag is then not deployed in
an accident. G
WARNING
If the PASSENGER AIRBA GOFF indicator lamp
is lit, the front-passenger fron tairbag is disa-
bled. It will not be deployed in the event of an
acciden tand cannot perform its intended pro-
tective function .Aperson 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
injur yore ven fatal injury.
When the front-passenger seat is occupied,
alway smake sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger fron tairbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
fron tairbag is correct. G
WARNING
If you secure achild on the co-driver's seat in
ar earward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struc kbythe airbag. There is an
increased risk of injury, possibly even fatal. 48

Suitability of the seats for attaching
abelt-secured child restraint system If you use
ababy car seat of category 0or0+orarearward-facing child restraint system of category
Ionar ear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch
the child restraint system.
If you use acategory I, forward-facing child restraint system, you should remove the head restraint
from the respective seat, if possible (Y page 106). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forward slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use is restricted. The maximum size settingoft he child restraint system is not possible due to possible
contact with the roof.
Always observe the notes in the "Childr estraint system" section (Ypage 56) and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system you must replace the head restraint sagain immediately
(Y page 105). All vehicle occupants must adjust their head restraint scorrectly before beginning the
journey.
