Seat belts
144WARNING
Adjust the height of the belt in such a way that the shoulder part of the belt is
positioned approximately across the middle of your shoulder - on no account
across your neck.
Note
It is also possible to adapt the routing of the belt webbing at the front seats by adjusting
the height of the seat.Taking seat belts off– Press the red button in the belt lock fig. 128 . The spring force causes the tongue
of the lock to jump out.
– Guide the belt back with your hand to en able the inertia reel to wind up the belt
webbing more easily.
A plastic knob in the belt webbing holds the be lt tongue in a position which is easy to
get hold of.Three-point seat belt for the rear middle seat
The three-point seat belt for the rear middle seat is anchored in the area
of the luggage compartment on the left side of the headliner.Your car is equipped as standard with the three-point seat belt
Fastening the seat belt– Pull the belt with both lock to ngues out of the headliner mount.
– Insert the lock tongue at the end of the belt into the seat belt buckle on the left side
until it is heard to lock in place.
– Pull the second lock tongue, which is move able on the seat belt, over the chest and
insert it into the belt buckle on the right side until it is heard to lock in place.
– Pull on the belt to check that both lock tongues are reliably engaged in the locks.
– The belt tongues for the rear middle seat are shaped differently so that they only fit into the respective belt buckle. If you attempt to insert a lock tongue into the wrong
belt lock it will not lock.Taking seat belt off– Take off the seat belt in the reverse order to fastening.
WARNING
The three-point safety belt for the rear middle seat can only fulfil its func-
tion reliably when the backrests are correctly locked into position page 74.
After releasing the seat belt hold it tight and let it slowly reel up until both
lock tongues lock into the headliner mount and are secured with a magnet - risk
of injury.
Never release simultaneously both tongues of the lock.
Belt tensionersSafety for the driver and front passenger wearing their seat belts is enhanced by the
belt tensioners fitted to the inertia reels of the front three-point seat belts, in addition
to the protection afforded by the airbag system.
The three-point seat belts are automatically te nsioned in the event of a frontal collision
of a certain severity. The belt tensioners can also be deployed if the seat belts are not
fastened.
The belt tensioner is deployed in the event of a frontal collision of major severity. A
powder charge is ignited in the inertia re els during deployment. The belt webbing is
pulled into the inertia reels by a mechanical system and the belt is tensioned.

Technical Data
The belt tensioners are not activated in case
of minor frontal and rear-end collisions,
in the case of vehicle rollover or accidents, through which no long delays are incurred
to the vehicle. In the case of a side collision, only the belt tensioner of the front seat on
the side on which the collision takes place is deployed.
WARNING
Any work on the system including removal and installation of system
components because of other repair work, must only be carried out by a
specialist garage.
The protective function of the system is only adequate for a single accident.
If the belt tensioners have been deployed, it is then necessary to replace the
entire system.
The Owner's Manual must also be handed over to the new owner if the
vehicle is sold.Note
Smoke is generated when the belt tensioners are deployed. This is not an indica-
tion of a fire in the vehicle.
It is essential to pay attent ion to relevant safety regulations if the vehicle or indi-
vidual parts of the system are scrapped. Specialist garages are familiar with these regu-
lations and will be able to provide you with detailed information in this respect.
When disposing of vehicle or parts of the system, it is important to comply with the
national legal requirements.

Airbag system
146
Airbag systemDescription of the airbag systemGeneral information on the airbag systemThe front airbag system is complementary to the three-point seat belts and offers addi-
tional protection for the head and chest area of the driver and passenger in the event
of a frontal collision.
In the case of a violent side cr ash, the side* and head airbags* reduce the risk of inju-
ries to the occupants on the side of the collision .
The airbag system is only functional af ter the ignition has been switched on.
The operational readiness of the airbag syst em is monitored electronically. The airbag
indicator light comes on for a few seconds each time the ignition is switched on.
The airbag system (according to vehicle equipment) consists of:
an electronic control unit,
the front airbags for the driver and front passenger,
driver's knee airbag*,
front side airbags*,
Rear side airbags*,
head airbags*,
an airbag indicator light in the instrument cluster,
a front passenger airbag switch page 154,
an indicator light for a switched off front seat passenger airbag in the middle of the
dash panel page 154.
A fault in the airbag system exists if:
the airbag indicator light does not light up when the ignition is switched on,
the warning light does not go out after about 4 seconds after the ignition is
switched on,
the airbag indicator light goes out and come s on again after the ignition is switched
on,
the airbag indicator light comes on or flickers when driving,
the airbag indicator light showing a swit ched-off front passenger airbag in the
middle of the dash panel flashes.
WARNING
To enable the occupants of a vehicle to be protected with the greatest
possible effect when the airbag is deployed, the front seats must be
page 138, “Correct seated position” co rrectly adjusted to match the body
size of the occupant.
If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, you are exposing yourself to increased risk
of injury in the event of an accident.
Have the airbag system checked immediat ely by a specialist garage if a fault
exists. Otherwise, there is a risk of the airbag not being activated in the event of
an accident.
No modifications of any kind may be made to parts of the airbag system.
It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.
The protective function of the airbag system is sufficient for only one acci-
dent. The airbag system must then be re placed if the airbag has been deployed.
The airbag system needs no maintenance during its working life.
If you sell your car, please hand over the complete vehicle documentation to
the new owener. Please note that the documents relating to the possibility of
deactivating the front passenger airbag are also part of the vehicle documents!
If the vehicle or individual parts of the airbag system are scrapped, it is
essential to observe the relevant safety precautions. Specialist garages are
familiar with these regulations.
When disposing of vehicle or parts of the airbag system, it is important to
comply with the national legal requirements.

Technical Data
When are the airbags deployed?The airbag system is designed in such a wa y that the driver and front passenger airbag
are deployed in the event of a violent frontal collision.
In the case of a violent side collision , the side airbag* on the side of the vehicle at
which the collision occurs, is deployed to gether with the relevant head airbag*.
In special cases, the front as well as th e relevant side and head airbags may be
deployed together.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary
greatly. An important role in this case is played by factors such as the type of object
against which the vehicle impacts (hard, soft ), the angle of impact, the relative speed
during the accident etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates the
relevant restraint system. If the vehicle deceleration which occurs and is measured
during the collision remains below the prescribed reference values specified in the
control unit, the airbags are no t deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
ignition is switched off;
a minor frontal collision;
a minor side collision;
a rear-end collision;
Rollover of the vehicle.Note
A grey white, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indicati on of a fire in the vehicle.
In the event of an accident in which the airbags are deployed:
the interior lighting comes on (if the swit ch for the interior light is in the door
contact position),
the hazard warning li ght is switched on;
all the doors are unlocked;
the fuel supply to the engine is interrupted.
Front airbagsDescription of the front airbags
The airbag system is not a su bstitute for the seat belt!Fig. 129 Driver airbag in the steering wheel / front passenger airbag in the dash panelThe front airbag for the driver is housed in the steering wheel fig. 129 - left. The front
airbag for the front passenger is housed in the dash panel above the storage compart-
ment fig. 129 - right. The installation positions are each marked with the “AIRBAG”
logo.
The front airbag system, in combination with three-point safety belts, offers additional
protection for the head and chest area of the driver and front passenger in the event of
a frontal collision of major severity page 148.
The airbag is not a substitute for the seat belt, but is part of the complete passive
vehicle safety concept. Please note that an airbag can only offer you optimal
protection in combination with a seat belt which is fastened .

Apart from their normal protective function, a further task of the seat belts is to also
hold the driver and front passenger in a correct seated position in the event of a frontal
collision so as to enable the front ai rbags to offer the maximum protection.
You should therefore always fasten the seat be lts, not only because this is required by
law, but also for safety reasons and for your own protection page 141, “Why seat
belts?”.
Note
The dash panel must be replaced after the front passenger airbag has been
deployed.Function of the front airbags
Risk of injury to the head and ches t area is reduced by fully inflated
airbags.The airbag system is designed in such a wa y that the airbags for the driver and front
passenger are deployed in the event of a violent frontal collision.
In certain accident situations, the front, side , knee and head airbag are simultaneously
deployed.
If the airbags are deployed, the airbags are filled with a propellant gas and inflated in
front of the driver and front passenger fig. 130 . The airbags inflate in fractions of a
second and at a high speed in order to be able to offer that additional protection in the
event of an accident. The forward movement of the driver and of the front passenger i s c us h i o n e d w h e n th e y m a ke co n t a c t w i t h t h e f u l l y i n f l a t e d a i r ba g a n d th e r i s k o f i n j u r y
to head and chest is thus reduced.
The specially developed airbag allows the gas
to flow out of the inflated airbag in a
controlled manner (depending on the load of the particular car occupant) in order to
cushion head and chest areas. The airbag then deflates subsequently to such an extent,
after an accident, to again provide a clear view forward.
A grey white, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indicati on of a fire in the vehicle.
The airbag develops enormous forces when triggered, which can lead to injuries if the
sitting position or seated position is not correct page 148.
Important safety information regarding the front airbag system
Correct use of the airbag system cons iderably reduces the risk of injury!
WARNING
Never transport children on the front seat of a vehicle without using a
proper restraint system. If airbags are de ployed in the event of an accident, the
child might suffer severe or even fatal injuries!
For the driver and front passenger it is important to maintain a distance of
at least 25 cm from the steering wheel or dash panel fig. 131 . Not main-
taining this minimum distance will mean that the airbag system will not be able
to properly protect you - hazard! The front seats and the head restraints must
always also be correctly adjusted to match the body size of the occupant.

Driver's knee airbag*Description of the driver's knee airbags
The knee airbag reduces the risk of injury to the legs.The driver's knee airbag is located in th e lower part of the dash panel below the
steering column fig. 132 . The fitting position is show n in a picture on the side
surface of the dash panel on the driver's side.
The driver's knee airbag is complementary to the three-point seat belt and offers
adequate protection to the knees of the driver. Please note that an airbag can only
offer you optimal protection in combination with a seat belt which is fastened .
Apart from their normal protective function, a further task of the seat belt is to also

Side airbags*Description of side airbags
The side airbag together with the head airbag offers enhanced occu-
pant protection in the event of a side collision.The front side airbags are housed in the upholstery of the seat backrests of the front
seats fig. 133 .
The side airbag system in combination with the three-point seat belts, offers additional
protection for the upper area of the body (chest, stomach and pelvis) of the occupants
of the vehicle in the event of severe side collisions page 151.
Apart from their normal protective function, a further task of the seat belts is to also
hold the occupents of the front or rear exteri or seats in a correct seated position in the
event of a side collision so as to enable th e side airbag to offer the maximum protec-
tion.
You should therefore always fasten the seat belts, not only because this is required by
law, but also for safety reasons and for your own protection.
Each time the side airbags are deployed, th e head airbag* and the front belt tensioner
on the side of the car on which the collision occures, are automatically deployed at the
same time in order to provide the occupant with enhanced protection.

Correct use of the airbag system cons iderably reduces the risk of injury!
WARNING
It is essential to always switch off page 154, “Deactivating an airbag” the
front passenger airbag when attaching a child safety seat on the front
passenger seat where the child is seated with its back facing in direction of
travel (in some countries also when the child is facing the direction of travel). If
this is not done, there is a risk of the ch ild suffering severe or even fatal injuries if the front passenger airbag is deploy
ed. In certain countries national legal
provisions also require that the side or head passenger airbags be deactivated.
When transporting a child on the front passenger seat, please comply with the
appropriate national regulations regarding the use of child safety seats.
Your head should never be positioned in the deployment area of the side
airbag. You might suffer severe injuries in the event of an accident. This applies
in particular to children who are transported without using a suitable child
safety seat page 158, “Child safety and side airbag*”.
If children adopt an incorrect seated position when travelling, they may be
exposed to an increased risk of injury in the event of an accident. This can result
in serious injuries page 156, “What you should know about transporting
children!”.
There must not be any further persons, animals as well as objects posi-
tioned between the occupants and the deployment area of the airbag. No
accessories, such as a can holder, should be attached to the doors.
The airbag control unit operates together with the pressure sensors, which
are attached in the front doors. For this reason no adjustments must be carried
out at the doors as well as at the door panels (for example additional installa-
tion of loudspeakers). Resulting damage s can have a negative affect on the
operation of the airbag system. All work on the front doors and their panels
must only be carried out by a specialist garage.
In the event of a side collision, the side airbags will not function properly, if
the sensors cannot measure the increasi ng air pressure inside the doors,
because the air can escape through lar ge, non-sealed openings in the door
panel.
Never drive with removed inner door panels.
Never drive, if parts of the inner door panel have been removed and the
remaining openings have not been properly sealed.
Never drive, if the loudspeakers in the doors have been removed, only if
the loudspeaker openings have been properly sealed.
Always make sure that the openings are covered or filled, if additional
loudspeakers or other equipment part s are installed in the inner door
panels.
