32Monitoring of airbag and belt tension device system
The functionality of the airbag and belt tension device system is constantly 
monitored electronically. Each time th e ignition is switched on, the warning 
lamp 
 lights for several seconds and the display in the instrument panel* 
shows  AIRBAG / TENSIONER .
The system must be checked when the warning lamp 
 :
•
does not come on when the ignition is switched on,
•
does not go out about 4 seconds after the ignition is switched on,
•
goes out and then comes on again after the ignition is switched on,
•
or if it comes on or flickers while the car is moving.
In the event of a malfunction, the warning lamp remains on continuously. In 
addition, depending on the malfunctio n, a fault message appears in the 
display of the combi-instrument for approx. 10 seconds and a short acoustic 
signal is given. In this event, you should have a qualified workshop check the 
system immediately.
If any of the airbags are de-activated by the Authorised Service Centre, the 
indicator lights for several  seconds more after the veri fication and will turn off 
if there is no fault.
WARNING
•
If there is a malfunction, the air bag and belt tension device system 
cannot properly perform its protective function.
•
If a malfunction should occur, have the system checked immediately by 
a qualified workshop. Otherwise there is a risk that, in the event of an acci-
dent, the airbag system and belt tension devices may not be triggered, or 
may not be triggered correctly.
Repair, care and disposal of the airbagsThe parts of the airbag system are installed in various places in your vehicle. 
If you work on the airbag system or remove and install parts of the system 
when performing other repair work, parts of the airbag system may be 
damaged. The consequence may be that, in the event of an accident, the 
airbag inflates incorrectly  or does not inflate at all.
The relevant safety requirements must be observed when the vehicle or 
components of the airbag are scrapped . The specialist workshops and the 
Vehicle disposal centres are familiar with these requirements.
WARNING
•
If repairs are not carried out by a professional, or if the airbags are used 
incorrectly, the risk of severe or fatal injuries is increased. The airbags may 
fail to inflate, or could inflate in the wrong circumstances.
•
Do not cover or stick anything on  the steering wheel hub or the soft 
plastic surface of the airbag unit on the passenger side of the dashboard, 
and do not obstruct or modify them in any way.
•
It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units.
•
To clean the steering wheel or dash panel, you may use only a dry cloth 
or one moistened with water. Never clean the dash panel and surface of the 
airbag module with cleansers containing solvents. Solvents cause the 
surface to become porous. If the airbag inflates, disintegrating plastic 
parts can cause substantial injuries.
•
Never attempt to repair, adjust, remove or install parts of the airbag 
system.
•
Any work on the airbag system or re moval and installation of the airbag 
components for other repairs (such as repairs to the steering wheel) should 
be performed only by a qualified workshop. Qualified workshops have the 
necessary tools, repair information and qualified personnel.

34Front airbagsDescription of front airbags
The airbag system is not a substitute for the seat belts.
The front airbag for the driver is located in the steering wheel  ⇒fig. 18  and 
the airbag for the front passenger is located in the dash panel  ⇒fig. 19. 
Airbags are identified by the text “AIRBAG”.
In conjunction with the seat belts,  the front airbag system gives the front 
occupants additional protection for the head and chest in the event of a 
severe frontal collision  ⇒page 37, “Safety notes on front airbag system”.
In addition to their normal function  of restraining the occupants, the seat 
belts also hold the driver  and front passenger in a position where the airbags 
can provide maximum protection in a frontal collision.
The airbag system is not a substitute for  seat belts, but is an integral part of 
the vehicle's overall passive safety system. Please bear in mind that the 
airbag system can only work effectively when the occupants are wearing their 
seat belts correctly and have adjusted the head restraints properly. For this 
reason, it is most important to wear the seat belts at all times - not only 
because this is required by law in most  countries, but also for your safety 
⇒ page 19, “Introduction”.
The main parts of the front airbag system are:•
an electronic control and monitoring system (control unit),
•
the two front airbags (airbag with gas generator) for the driver and front 
passenger,
•
a warning lamp 
 in the dash panel insert ⇒ page 31.
The functionality of the airbag system is monitored electronically. The airbag 
warning lamp will light up for a few  seconds every time the ignition is 
switched on (self-diagnosis).
There is a fault in the system if the warning lamp 
•
does not come on when the ignition is switched on  ⇒page 31,
•
does not go out about 4 seconds af ter the ignition is switched on,
•
goes out and then comes on again after the ignition is switched on,
•
or if it comes on or flickers while the car is moving.

The front airbag system will not be triggered if:
•
if the ignition is switched off,
•
during a minor frontal collision,
•
during a side collision,
•
during a rear-end collision,
•
or if the vehicle rolls.
WARNING
•
The seat belts and airbags can only provide maximum protection if the 
occupants are seated correctly  ⇒page 10, “Proper sitting position for 
occupants”.
•
If a fault should occur in the airbag system, have the system checked 
immediately by a qualified workshop. Otherwise there is a danger that 
during a frontal collision, the system may fail to trigger, or not trigger 
correctly.
Function of front airbags
Inflated airbags reduce the risk of head or chest injury.The airbag system is designed so that the airbags for the driver and front 
passenger are triggered in a severe frontal collision.
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbags fill with a propellant gas and 
deploy in front of the driver and front passenger  ⇒fig. 20 . The fully deployed 
airbags cushion the forward movement of the front occupants and help to 
reduce the risk of injury to the head and the upper part of the body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and 
chest are surrounded and protected by the airbag. Once the impact has been 
absorbed, the airbag deflates sufficiently for the front occupants to see 
forward.

Safety notes on front airbag system
If you use airbags correctly, they can considerably reduce the 
risk of injury in many kinds of accident.
WARNING
•
It is important for the driver and front passenger to maintain a distance 
of at least 25 cm from the steering wheel or dash panel. If the minimum 
distance is not observed then the airbags do not correctly protect the 
vehicle occupants; risk of fatal injuries! In addition, the front seats and 
head restraints must always be positioned correctly for the height of the 
occupant.
•
If you are not wearing a seat belt or if you lean forward or to the side or 
assume an incorrect sitting position, the risk of injury is increased 
substantially. This increased risk of injury will be further increased if you 
are struck by an inflating airbag.
•
Never let a child travel on the front seat without an appropriate restraint 
system. If the airbag is triggered in an accident, children can sustain 
serious or fatal injuries from the airbag as it inflates  ⇒page 46, “Child 
safety”.
•
Occupants sitting in the front of the vehicle must never carry any 
objects or pets in the deployment sp ace between them and the airbags, or 
allow children or other passengers to travel in this position.
•
The airbags provide protection for one accident only, if they have been 
deployed they must be replaced.
•
It is also important not to attach any objects such as cup holders or 
telephone mountings to the surfaces covering the airbag units.
•
Do not attempt to modify components of the airbag system in any 
way.
Side airbags*Description of side airbags
The airbag system is not a substitute for the seat belts.The front side airbags are located in the driver seat and front passenger seat 
backrests  ⇒fig. 22. The rear side airbags are located in the rear wheel 
housing lining. The locations are identified by the text “AIRBAG” in the upper 
region of the backrests and in the rear wheel housing lining.
In conjunction with the seat belts, the side airbag system gives the front seat 
occupants additional protection for the upper body in the event of a severe 
side collision  ⇒page 40, “Safety notes on the operation of the side airbag 
system”.
In a side collision the side airbags reduce the risk of injury to passengers on 
the front seats to the areas of the body facing the impact. In addition to their 
normal function of protecting the occupan ts in a collision, the seat belts also

The functionality of the airbag system is monitored electronically. The airbag 
warning lamp will light up for approx.  4 seconds every time the ignition is 
switched on (self-diagnosis).
WARNING
•
In a side-on collision, the side airb ags will not work, if the sensors do 
not correctly measure the pressure increase on the interior of the doors, 
due to air escaping through the areas with holes or openings in the door 
panel.
•
Never drive the vehicle if the interior panels have been removed.
•
Never drive if the interior door panels have been removed or if the 
panels have not been correctly fitted.
•
Never drive the vehicle if the loudspeakers in the door panels have 
been removed, unless the holes left by the loudspeakers have been 
correctly closed.
•
Always check that the openings are closed or covered if loudspeakers 
or other equipment are fitted in the interior door panels.
•
Any work carried out to the doors sh ould be made in a qualified author-
ised workshop.
•
The seat belts and airbags can only  provide maximum protection if the 
occupants are seated correctly  ⇒page 10, “Proper sitting position for 
occupants”.

40Safety notes on the operation of the side airbag system
If airbags are used correctly, they can considerably reduce the 
risk of injury in side impact collisions.
WARNING
•
If you do not wear a seat belt, if  you lean forward, or are not seated 
correctly while the vehicle is in motion, you are at greater risk of injury 
should the side airbag system be triggered in an accident.
•
In order for the side airbags to provide their maximum protection, the 
prescribed sitting position must always be maintained with seat belts 
fastened while travelling.
•
Occupants of the outer seats must never carry any objects or pets in the 
deployment space between them and th e airbags, or allow children or 
other passengers to travel in this position. It is also important not to attach 
any accessories (such as cup holders) to the doors. This would impair the 
protection offered by the side airbags.
•
The built-in coat hooks should be used only for lightweight clothing. Do 
not leave any heavy or sharp-edged objects in the pockets.
•
Great forces, such as hard blows or kicks, must not be exerted upon the 
backrest bolster because the system may  be damaged. In this case the side 
airbags would not be triggered.
•
Under no circumstances should protective covers be fitted over the 
driver seat or front passenger seat unless the covers have been expressly 
approved for use in your vehicle. Because the airbag deploys from the side 
of the backrest, the use of non-approved seat covers would obstruct the 
side airbag seriously reducing the airbag's effectiveness  ⇒page 210, 
“Accessories, parts replacement and modifications”.
•
Any damage to the original seat upho lstery or around the seams of the 
side airbag units must be repaired immediately by a qualified workshop.
•
The airbags provide protection for one  accident only, if they have been 
deployed they must be replaced.
•
When children assume an incorrect si tting position, they expose them-
selves to an increased risk of injury in the event of an accident. This is 
particularly the case if the child is travelling on the front passenger seat 
and the airbag system is triggered in an accident; this could have critical 
consequences including serious injury or death  ⇒page 46, “Child safety”.
•
Any work on the side airbag system or removal and installation of the 
airbag components for other repairs (such as removal of the front seat) 
should only be performed by a qualified workshop. Otherwise, a fault may 
be introduced into the operation of the airbag system.
•
Do not attempt to modify components of the airbag system in any way.
•
The side and head airbags are managed through sensors located in the 
interior of the front doors. To ensure the correct functioning of the side and 
head airbags neither the doors nor the  door panels should be modified in 
any way (e.g. fitting loudspeakers). If the front door is damaged in any way, 
this may affect the correct working of the system. All work carried out on 
the front door must be made in a qualified workshop.WARNING (continued)
