Seat belt protection
Passengers not wearing seat belts risk severe injuries in the
event of an accident.Properly worn seat belts hold the vehicle occupants in the correct sitting posi-
tions and substantially reduce the kinetic energy in the event of an accident.
Seat belts also help to prevent uncontrolled movements that could lead to
severe injuries. In addition, properly worn seat belts reduce the danger of
being thrown from the car.
Passengers wearing their seat belts correctly benefit greatly from the ability
of the belts to absorb kinetic energy. The front part of your vehicle and other
passive safety features (such as the airbag system) are also designed to
absorb the kinetic energy released in a collision. Taken together, all these
features reduce the releasing kinetic energy and consequently, the risk of
injury.
Our examples describe frontal collisions. Of course, properly worn seat belts
substantially reduce the risk of injury in all other types of accidents. This is why it is so important to fasten seat belts before every trip, even when "just
driving around the corner".
Ensure that your passengers wear their seat belts as well. Accident statistics
have shown that wearing seat belts is an effective means of substantially
reducing the risk of injury and improving the chances of survival in a serious
accident. Furthermore, properly worn seat belts improve the protection
provided by airbags in the event of an accident. For this reason, wearing a
seat belt is required by law in most countries.
Although your vehicle is equipped with airbags, the seat belts must be
fastened and worn. The front airbags, for example, are only triggered in some
frontal accidents. The front airbags will
not be triggered during minor frontal
collisions, minor side collisions, rear collisions, rolls or accidents in which the
airbag trigger threshold value in the control unit is not exceeded.
Therefore, you should always wear your seat belt and ensure that your
passengers have fastened their seat belts properly before you drive off!
Safety instructions on using seat belts
If seat belts are used correctly, they can reduce the risk of
injury in an accident.– Always wear the seat belt as described in this section.
– Ensure that the seat belts can be fastened at all times and are not damaged.
WARNING
•If the seat belts are worn incorrectly or not at all, the risk of severe inju-
ries increases. The optimal protection from seat belts can be achieved only
if you use them properly.

– Take hold of the top guide fitting and slide it up or down so that the shoulder part of the seat belt is positioned roughly midway
over the shoulder, although it must never rest against the neck
⇒ page 25, fig. 16 ⇒ in “Seat belt position” on page 23.
– After adjusting, pull the belt sharply to check that the catch on the guide fitting is engaged securely.
NoteIt is also possible to adjust the height of the front seats to obtain the best
position for the front seat belts.Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe or even mortal
injuries.Seat belts can provide optimal protection only if the belt web is
properly worn. The seat belts must be fastened exactly in the order
described in this chapter. An in correct sitting position impairs
substantially the protection a seat belt offers and can lead to severe
or fatal injuries. The risk of severe or fatal injuries is especially
increased when a deploying airbag strikes an occupant who has
assumed an incorrect sitting position. As the driver, you are respon-
sible for all vehicle occupants, especially children. Therefore:
– Never allow anyone to wear the seat belt incorrectly while the vehicle is moving ⇒.
WARNING
•An incorrectly worn seat belt increases the risk of severe injuries.•Before every trip, instruct your passengers to adjust their seat belts
properly and to wear them for the whole journey.•Read and always observe information and warnings concerning the use
of seat belts ⇒page 21.
Belt tension devicesFunction of the belt tension device
During a frontal collision, the seat belts on the front seats are
retracted automatically.The seat belts for the front occupants are equipped with belt tension devices.
Sensors will trigger the belt tension devices during severe head-on, lateral
and rear collisions only if the seat belt is being worn. This retracts and
tightens the seat belts, reducing the forward motion of the occupants.
The belt tension device can be triggered only once.
The belt tension devices will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns or in situations where no large
forces act on the front, side or rear of the vehicle.
Note
•If the belt tension devices are triggered, a fine dust is produced. This is
normal and it is not an indication of fire in the vehicle.

The danger of fitting a child seat on the front passenger seat
Rear-facing child seats must never be used on the front
passenger seat when the front passenger airbag is enabled.An enabled front airbag on the front passenger side is potentially a major
danger to a child. The front passenger seat is life threatening to a child if
he/she is transported in a rear-facing child seat. You should always transport
all children up to 12 years of age on the rear seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such great force that critical or fatal injuries may
result.
Therefore we strongly recommend you to transport children on the rear seats.
That is the safest place for children in the vehicle. Alternatively, the front
passenger airbag can be disabled with a key-operated switch ⇒page 44.
When transporting children, use a child seat appropriate to the age and size
of each child ⇒ page 46.
For those vehicles that do not include a key lock switch to turn the airbag off,
an Authorised Service Centre must be consulted.
WARNING
•If a child seat is secured to the front passenger seat, the risk to the child
of sustaining critical or fatal injuries in the event of an accident increases.•Never secure a rear-facing child seat to the front passenger seat if the
front passenger airbag is enabled. The child can suffer critical or fatal inju-
ries when the front passenger airbag is triggered.
•An inflating front passenger airbag can strike the rear-facing child seat
and hurl it with great force against the door, the roof or the backrest.•If, under special circumstances, it is necessary to transport a child in a
rear-facing child seat on the front passenger seat, it is absolutely essential
that you observe the following safety measures:
−Disable the front passenger airbag ⇒page 44, “Deactivating
airbags*”.
− The child seat must be approved by the child seat manufacturer for
use on a front passenger seat with front or side airbag.
− Follow the installation instructions given by the child seat manufac-
turer and observe the safety instructions ⇒page 46, “Child safety”.
− Before properly installing the child seat, push the front passenger
seat completely backwards so that the greatest possible distance to
the front passenger airbag is ensured.
− Ensure that no objects prevent the front passenger seat from being
pushed completely back.
− The backrest of the front passenger seat must be in an upright
position.

30Monitoring of airbag and belt tension device system
Both the airbag and belt tension device systems operation is constantly
monitored electronically. The warning lamp
 will light every time the igni-
tion is switched on until you attach your seatbelt.
The system must be checked when the warning lamp
 :
•does not light up when the ignition is switched on,•it turns off and then lights up again after the ignition is switched on,•lights up or flashes while the car is moving.
In the event of a malfunction, the warning lamp remains on continuously.
Have the system inspected immediately by a qualified workshop.
If any of the airbags are de-activated by the Authorised Service Centre, the
indicator lights for several seconds more after the verification and will turn off
if there is no fault.WARNING
•If there is a malfunction, the airbag and belt tension device system
cannot properly perform its protective function.•If a malfunction occurred, have the system checked immediately by a
qualified workshop. Otherwise, in th e event of an accident, the airbag
system and belt tension devices may not be triggered, or may not be trig-
gered correctly.
Repairs, maintenance 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 fit 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
incorrectl y, the ris k of severe or fatal inju ries is increase d. T he 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 or a
water-moistened cloth. Never clean the dash panel and the airbag module
surface with cleansers containing solvents. Solvents cause the surface to
become porous. If the airbag triggered, disintegrating plastic parts could
cause substantial injuries.•Never attempt to repair, adjust, remove or install parts of the airbag
system.•Any work on the airbag system or removal and installation of the airbag
components for other repairs (such as repairs to the steering wheel) should
be performed only by a qualified wo rkshop. Qualified workshops have the
necessary tools, repair inform ation and qualified personnel.•We strongly recommend you to go to a qualified workshop for all work
on the airbag system.•Never attempt to alter the front bumper or the body.•The airbags provide protection for just one accident; replace them once
they have deployed.

32The 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 knee airbag* for the driver,•a warning lamp
 in the dash panel insert ⇒page 29.
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 29•it turns off and then lights up again after the ignition is switched on,•lights up or flashes while the car is moving.
The 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 occurred 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

34Safety 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.•I f yo u are n o t w ea r i ng a s ea t b e l t , i f yo u l e an fo r w a rd o r t o t h e s id e w h il e
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 46, “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.
Knee airbag*Description of the knee airbag
The airbag system provides additional protection to front seat
passengers if they are properly secured.The knee airbag for the driver is located in the instrument panel underneath
the steering wheel ⇒fig. 21.
The knee airbag offers additional protection to the driver's knees and upper
and lower thigh areas as a supplement to the safety belts.
If the front airbags deploy, the knee airbag also deploys in severe frontal colli-
sions ⇒page 32.
Besides their normal safety function, safety belts help keep the driver in posi-
tion in case of a frontal collision so that the airbags can provide protection.
The airbag system is not a substitute for seat belts. It is, on the other hand,
part of the overall occupant safety system of your vehicle. Always remember

that the airbag system can only help to protect you if you are wearing your
safety belt and wearing it properly.
Remember too that airbags will deploy only once and only in certain kinds of
accidents - your safety belts are always there to offer protection in those acci-
d e nts i n whi ch a ir ba gs a re not supp os ed t o de ploy or wh en the y hav e alr ead y
deployed, for example when your vehicle strikes or is struck by another after
the first collision.
This is just one of the reasons why an airbag is not a substitute for the safety
belt. The airbag system works most effectively when used with the safety
belts. Therefore, always wear your safety belts correctly.
It is important to remember that while the supplemental airbag system is
designed to reduce the likelihood of serious injuries, other injuries, for
example, swelling, bruising, and minor abrasions can also be associated with
airbags.
The knee airbag system basically consists of:
•The electronic control module•One inflatable airbag (airbag and gas generator) for the driver•An airbag indicator light in the instrument panel
The knee airbag system will not deploy:•when the ignition is turned off•in frontal collisions when the deceleration measured by the control unit is
too low•in side collisions•in rear-end collisions•in rollovers•in the event of a system malfunction (warning/indicator light illuminated)
⇒ page 65.
WARNING
•Safety belts and the airbag system can only provide protection when
occupants are in the proper seating position.•If the airbag indicator light comes on when the vehicle is being used,
have the system inspected immediately by your Authorised Service Centre.
The airbag may not work properly when the vehicle acceleration in a side
collision is high enough to deploy the airbag. See also ⇒page 65.
How knee airbags work
The risk of injury to the leg area is reduced by fully deployed
knee airbags.The knee airbag system has been designed so that the airbag for the driver is
deployed in certain but not all frontal collisions.

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's seat and front passenger's
seat backrests ⇒fig. 23. 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.
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 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 occupants in a collision, the seat belts also hold the passengers in the front seats and the outer rear seats in a position
where the side airbags can provide maximum protection.
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. Therefore, 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 18, “Brief introduction”.
The side airbag system will not be triggered if:
•the ignition is switched off,•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 front side airbags in the backrests of the front seats and the rear side
airbags in the lining of the rear wheel housing.•a warning lamp
 in the dash panel insert ⇒page 29.
The airbag system operation 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 airbags 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.
