Seat belts
Introduction Ac
orrectly fastened seat belt is the most effec-
tive means of restraining the movement of vehi- cle occupants in the event of an accident or
overturn .This reduces the risk of vehicle occu-
pants coming into contact with parts of the vehi-
cle interior or being thrown from the vehicle. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag deployed.
The seat belt system consistso f:
R Seat belts
R Belt tensioners and belt force limiters
If the seat belt is pulled quickly or suddenly from the belt sash guide, the inertia reel locks. The
belt strap cannot be pulled out further.
The belt tensioner tightenst he seat belt to lie
close against your body in the event of acolli-
sion. However, it does not pull the vehicle occu-
pants back towards the seat backrest.
The belt tensioner also does not correct an
incorrec tseat position or the strap layoutofa
seat belt that is worn incorrectly.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which take
on apart of the deceleration force. This makes it
possible to reduce the forces to which vehicle
occupants are subjected during an accident.
! If the co-driver's seat is not occupied, do not
engage the seat belt tongue in the buckle on
the co-driver's seat. Otherwise, the belt ten-
sioner could be triggered in the event of an
accident and would have to be replaced.
Important safety notes G
WARNING
The seat belt cannot perform its intended pro- tective function if it is not fastened correctly. Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal. Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly.
G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtallc annot wear the
seat belts correctl ywithou tas uitable, addi-
tional restraint system. The seat belt cannot

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
Occupant safetySafety

In this case, always ensure that the co-driver's
airbag is disabled.T he PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG

WARNING
If you secure achild in aforward-facing child
restraint system on the front-passenger seat
and you positio nthe 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 ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Alwaysm ove the front-passenger seat as far
back as possible and fullyr etract the seat
cushio nlength. Alwaysm ake sure that the
shoulder belt strap is correctly routed from
the vehicle belt outlet to the shoulder belt
guideont he child restraint system. The shoul-
der belt strap must be routed forward sand
downwards from the vehicle belt outlet. If
necessary ,adjust the vehicle belt outlet and
the front-passenger seat accordingly .Always
observe the information abouts uitable posi-
tioning of the child restraint system in this
Owner's Manualasw ell as the child restraint
system manufacturer's installation instruc-
tions.
If the automatic co-driver's front airbag deacti-
vation system detects that:
R the co-driver's seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and remains lit. This indicates that the co-driver's
front airbag is disabled.
R the co-driver's seat is occupie dbyachild in a
rearward-facing child restraint system, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the co-driver's front airbag is disabled.
But in the case of achild in arearward-facing
child restraint system, the PASSENGER AIR
BAG ON indicator lamp can be lit continuously
after the system self-test. This indicates that
the co-driver's front airbag is enabled. The
resultoft he classification is dependent on,
among other factors, the child restraint sys-
tem and the child's stature. It is recommen-
ded that you fit the child restraint system to a
suitable rear seat.
R the co-driver's seat is occupie dbyachild in a
forward-facing child restraint system, either
the PASSENGER AIR BAG ON or PASSENGER
AIR BAG OFF indicator lamp lights up after the
system self-test depending on the resultof
the classification and remains lit. The resultof the classification is dependent on, among
other factors, the child restraint system and
the child's stature.
Move the co-driver's seat as far back as pos-
sible. Alwayso bserve the information on
"Child restraint systems on the co-driver's
seat" (Y page 59) and on "Suitable posi-
tioning of the child restraint system"
(Y page 60). Alternatively ,fit the child
