Front 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. 17 and
the airbag for the front passenger is located in the instrument panel
⇒ fig. 18 . Airbags are identified by the word “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 36, “Safety notes on the frontal airbag
system”.
In addition to their normal function of restraining the occupants, the seat
belts also hold the driver and front pas senger 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 it 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. Therefore,
it is most important to wear the seat belts at all times, not only because this
is required by law in most coun tries, but also for your safety ⇒page 19,
“Brief 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 30.
The airbag system operation 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 light up when the ignition is switched on ⇒page 30,
•
after the ignition is switched on, it turns off after 4 seconds,
•
it turns off and then lights up again after the ignition is switched on,
•
lights up or flashes while the car is moving.

34The front airbag system will not be triggered if:•
the ignition is switched off,
•
there is a minor frontal collision,
•
there is a side collision,
•
there is a rear-end collision,
•
the vehicle turns over.
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 has occured in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise, during a frontal collision
the system may fail to trigger, or not trigger correctly.
Operation of frontal 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. 19 . 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. After the collision, the
airbag deflates sufficiently for the front occupants to see forward.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust

may develop when the airbag deploys. This is normal and it is not an indica-
tion of fire in the vehicle.

36Safety notes on the frontal 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 keep 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, if you lean forward or to the side while
travelling or assume an incorrect sitting position, there is a substantially
increased risk of injury. 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 45, “Child
safety”.
•
The deployment space between the front passengers and the airbags
must not in any case be occupied by other passenger, pets and objects.
•
The airbags provide protection for just one accident; replace them once
they have deployed.
•
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 side airbags are located in the backrest cushions of the driver seat
⇒ fig. 21 and the front passenger seat as well as in the rear seats. The loca-
tions are identified by the text “AIRBAG” in the upper region of the backrests.
Together with the seat belts, the side airbag system gives the front seat occu-
pants additional protection for the upper body in the event of a severe side
collision ⇒page 39, “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 occupants in a collision, the seat belts also
hold the passengers on the front seats and the outer rear seats in a position
where the side airbags can provide maximum protection.

not only because this is required by la
w in most countries, but also for your
safety ⇒page 19, “Brief Introduction”.
The side airbag system will not be triggered if:
•

there is a minor side collision,
•
there is a frontal collision,
•
there is a rear-end collision,
•
the vehicle turns over.
The main parts of the airbag system are:
•
an electronic control and monitoring system (control unit),
•
the side airbags in the sides of the backrests of the front and rear seats,
•
a warning lamp

The airbag system operation is monito red 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 air bags will not work, if the sensors do
not correctly measure the pressure incr ease 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 should 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”.
•
If a fault has occured in the airbag system, have the system checked
immediately by a qualified workshop. Ot herwise, during a side collision,
the system may fail to trigger, or not trigger correctly.WARNING (continued)

38Function of side airbags
Inflated airbags can reduce the risk of head or chest injury in
many side impact collisions.In some side collisions the side airbag is triggered on the impact side of the
vehicle ⇒page 38, fig. 22 .
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust
may develop when the airbag deploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The fully deployed airbags cushion th e movement of the occupants of the
front seats and the outer rear seats and help to reduce the risk of injury to the
upper 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.

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 a greater risk of injury if
the side airbag system is triggered in an accident.
•
In order for the side airbags to provide their maximum protection, the
prescribed sitting position must alwa ys 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 is triggered 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 200,
“Accessories, parts replacement and modifications”.
•
Any damage to the original seat uphol stery or around the seams of the
side airbag units must be repaired immediately by a qualified workshop.
•
The airbags provide protection for just one accident; replace them once
they have deployed.
•
When children assume an incorrect sitting 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 45, “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, faults may
occur during the airbag system operation.
•
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, the airbag
system may not work correctly. All work carried out on the front door must
be made in a qualified workshop.WARNING (continued)
