Seat belts
Vehicle occupants not wearing seat belts are not “attached” to the vehicle.
In a head-on collision, they will move forward at the same speed their vehi-
cle was travelling just before the impact. This example applies not only to
head-on collisions, but to all accidents and collisions. 
The danger of not using the seat belt
The general belief that the passengers can protect them-
selves with their hands in a minor collision is false.

ing a seat belt is thrown

seat is thrown forward vi-
olently, hitting the driver
wearing a seat belt
Even at low speeds the forces acting on the body in a collision are so great
that it is not possible to brace oneself with one's hands. In a frontal colli-
sion, unbelted vehicle occupants are thrown forward and will make violent
contact with the steering wheel, dash panel, windscreen or whatever else is
in the way ⇒ Fig. 9.
The airbag system is not a substitute for seat belts. When triggered, airbags
provide only additional protection. All occupants (including the driver) must
wear seat belts properly at all times during the trip. This will reduce the risk
of severe injuries in the event of an accident – regardless of whether an air-
bag is fitted for the seat or not.
Note that airbags can be triggered only once. To achieve the best possible
protection, the seat belt must always be worn properly so that you will be
protected in accidents in which no airbag is deployed.
It is also important for the rear passengers to wear seat belts properly, as
they could otherwise be thrown forward violently through the vehicle interi-
or in an accident. Passengers in the rear seats who do not use seat belts
endanger not only themselves but also the front occupants ⇒ Fig. 10.

Seat belt protection
Passengers not wearing seat belts risk severe injuries in the
event of an accident.

sharp braking
Properly worn seat belts hold the vehicle occupants in the correct sitting po-
sitions and substantially reduce the kinetic energy in the event of an acci-
dent. Seat belts also help to prevent uncontrolled movements that could
lead to severe injuries. In addition, properly worn seat belts reduce the dan-
ger of being thrown from the vehicle.
Vehicle occupants 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 de-
signed 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 seri-
ous 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 fas-
tened 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, overturns 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 all vehicle
occupants have fastened their seat belts properly before you drive off!

Safety instructions on using seat belts
If seat belts are used correctly, they can considerably 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. 

Seat belts
– Guide the belt back by hand so that it rolls up easily and the
trim is not damaged.
WARNING
Never unbuckle a seat belt while the vehicle is in motion. If you do, you
increase the risk of sustaining severe or fatal injuries.

Seat belt height adjustment
Seat belt height adjusters can be used to adjust the height
of the shoulder area of the seat belt.
Fig. 17 Belt height ad-
juster
The belt height adjuster can be lowered by keeping the button
pressed down at the same time.
– Press button ⇒ 
Fig. 17 1
to adjust the belt height. –
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
⇒ Fig. 17 2
⇒  in Seat belt position on page 25.
– After adjusting, pull the belt sharply to check that the catch on
the guide fitting is engaged securely.
Note
It 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 incorrect sitting position impairs sub-
stantially the protection a seat belt offers and can lead to severe or
fatal injuries. The risk of severe or fatal injuries is especially in-
creased when a deploying airbag strikes a vehicle occupant who
has assumed an incorrect sitting position. As the driver, you are re-
sponsible for yourself and all passengers, especially children.
Therefore:
– Never allow anyone to wear the seat belt incorrectly while the
vehicle is moving ⇒

Brief introduction Why wear a seat belt and assume the correct sitting
position?
For the inflating airbags to achieve the best protection, the
seat belt must always be worn properly and the correct sit-
ting position must be assumed.For your own safety and the safety of the passengers, please en-
sure the following before driving:
– Always wear the seat belt properly ⇒ page 19.
– Adjust the driver seat and the steering wheel correctly
⇒ page 10.
– Adjust the front passenger seat correctly ⇒ page 11.
– Adjust the head restraint correctly ⇒ page 13.
– Use the correct child restraint system to protect children in your
vehicle ⇒ page 47.
The airbag is deployed at high speed in fractions of a second. If you have an
incorrect seating position at the time the airbag is deployed, it could cause
you critical injuries. Therefore, it is essential that all vehicle occupants as-
sume a correct sitting position while travelling.
Sharp braking before an accident may cause a passenger not wearing a seat
belt to be thrown forward into the area of the deploying airbag. In this case, the inflating airbag may inflict critical or fatal injuries on the occupant. This
also applies to children.
Always maintain the greatest possible distance between yourself and the
front airbag. This way, the front airbags can completely deploy when trig-
gered, providing their maximum protection.
The most important factors that will trigger an airbag are: the type of acci-
dent, the angle of collision and the speed of the vehicle.
Whether the airbags are triggered depends primarily on the vehicle deceler-
ation rate resulting from the collision and detected by the control unit. If the
vehicle deceleration occurring during the collision and measured by the
control unit remains below the specified reference values, the front, side
and/or curtain airbag will not be triggered. Take into account that the visible
damage in a vehicle involved in an accident, no matter how serious, is not a
determining factor for the airbags to have been triggered.
WARNING
● Wearing the seat belt incorrectly or assuming an incorrect sitting po-
sition can lead to critical or fatal injuries.
● All vehicle occupants, including children, who are not properly belted
can sustain critical or fatal injuries if the airbag is triggered. Children up
to 12 years old should always travel on the rear seat. Never transport
children in the vehicle if they are not restrained or the restraint system is
not appropriate for their age, size or weight.
● 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 sub-
stantially increased risk of injury. This increased risk of injury will be fur-
ther increased if you are struck by an inflating airbag. 

WARNING (Continued)
● To reduce the risk of injury from an inflating airbag, always wear the
seat belt properly ⇒ page 19.
● Always adjust the front seats properly.

The danger of fitting a child seat on the front passenger
seat
Rear-facing child seats must never be used on the front pas-
senger seat when the front passenger airbag is enabled. The front passenger front airbag is a serious risk for a child if it is activated.
The front passenger seat is life threatening to a child if he/she is transpor-
ted in a rear-facing child seat. Children up to 12 years old should always
travel 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 force that it can cause critical or fatal injuries.
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 45. When transporting children, use a child seat suitable for the
age and size of each child ⇒ page 47.
For those vehicles that do not include a key lock switch to deactivate the air-
bag, the vehicle must be taken to a Technical Service.
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 in-
creases.
● 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 in-
juries if the front passenger airbag is triggered.
● An inflating front passenger airbag can strike the rear-facing child
seat and project it with great force against the door, the roof or the back-
rest.
● 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 es-
sential that you observe the following safety measures:
–Deactivate the front passenger airbag ⇒ page 45, Deactivating
airbags.
– Child seats 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 manu-
facturer and observe the safety instructions ⇒ page 47, Child safe-
ty.
– 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 po-
sition.

Airbag system
Control lamp for airbag and seat belt tensioner 
This control lamp monitors the airbag and seat belt tension-
er system.
The control lamp monitors all airbags and seat belt tensioners in the vehi-
cle, including control units and wiring connections.
Monitoring of airbag and belt tensioner system
Both the airbag and belt tensioner systems operation is constantly moni-
tored electronically. The control lamp  will light every time the ignition is
switched on until you attach your seatbelt.
The system must be checked when the control lamp  :
● does not light up when the ignition is switched on
● turns off and then lights up again after the ignition is switched on
● lights up or flashes while the vehicle is moving
In the event of a malfunction, the warning lamp remains on continuously.
Have the system inspected immediately by a specialised workshop.
If any of the airbags are disabled by a Technical Service, the warning lamp
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 tensioner system cannot
properly perform its protective function.
● If a malfunction occurred, have the system checked immediately by a
specialised workshop. Otherwise, in the event of an accident, the airbag
system and belt tensioners may not be triggered, or may not be triggered
correctly.
 Repairs, maintenance and disposal of airbags
The parts of the airbag system are installed in various places in your vehi-
cle. If work is carried out on the airbag system or parts have to be removed
and fitted on the system when performing other repair work, parts of the air-
bag system may be damaged. In the event of an accident this could cause
the airbag to inflate incorrectly or not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are
scrapped. Specialised workshops and 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 air-
bags may fail to inflate, or could inflate in the wrong circumstances.
● Do not cover or stick anything on the steering wheel hub or the sur-
face of the airbag unit on the passenger side of the dash panel, 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 mod-
ule surface with cleaners containing solvents. Solvents cause the surface
to become porous. If the airbag triggered, plastic parts could become de-
tached and cause injuries.
● Never attempt to repair, adjust, remove or install parts of the airbag
system. 

WARNING (Continued)
● Any work on the airbag system or removal and installation of the air-
bag components for other repairs (such as repairs to the steering wheel)
should be performed only by a specialised workshop. Specialised work-
shops have the necessary tools, repair information and qualified person-
nel.
● We strongly recommend you to go to a specialised 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.
For the sake of the environment
The airbags, which are a special type of waste, must be disposed of through
an authorised service, because they contain pyrotechnic elements. 

Front airbags
Description of front airbags
The airbag system is not a substitute for the seat belts.
Fig. 18 Driver airbag in
the steering wheel and
knee airbag in the dash
panel
Fig. 19 Front passenger
airbag located in dash
panel 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. Air-
bags are identified by the word “AIRBAG”. On the driver side, the knee air-
bag* is found in the footwell lining, under the instrument panel.
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 se-
vere frontal collision ⇒ page 36, Safety notes on the 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 air-
bags 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 vehicle 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 countries, 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 knee airbag* for the driver,
● a control lamp  on the dash panel ⇒ page 31
The airbag system operation is monitored electronically. The airbag control
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 control lamp :
● does not light up when the ignition is switched on ⇒ page 31
● turns off and then lights up again after the ignition is switched on
● lights up or flashes while the vehicle is moving 
