The seat belt cannot offer its full protection if the seat belt is not
positioned correctly.
– Adjust the seat and head restraint correctly.
– To fasten the belt, take hold of the latch plate and pull it slowly
across your chest and lap.
– Insert the latch plate into the buckle for the appropriate seat
and push it down until it is securely locked with an audible click
⇒ Fig. 11. –
Pull the belt to ensure that the latch plate is securely engaged
in the buckle.
The seat belts are equipped with an automatic retractor on the shoulder
strap. Full freedom of movement is permitted when the shoulder belt is
pulled slowly. However, during sudden braking, during travel in steep areas
or bends and during acceleration, the automatic retractor on the shoulder
belt is locked.
The automatic belt retractors on the front seats are fitted with seat belt ten-
sioners ⇒ page 28.
WARNING
● An incorrectly worn seat belt can cause severe injuries in the event of
an accident.
● The seat belts offer best protection only when the backrests are in an
upright position and the seat belts have been fastened properly.
● Never put the latch plate in the buckle of another seat. If you do this,
the seat belt will not protect you properly and the risk of injury is in-
creased.
● If a vehicle occupant is incorrectly belted in, the seat belt cannot pro-
tect him or her properly. An incorrectly positioned seat belt can cause ex-
tremely severe injuries.
● Always engage the retractor lock when you are securing a child seat
in group 0, 0+ or 1 ⇒ page 47.

–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.

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 ⇒ 
.
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 23.

Seat belt tensioners
Function of the seat belt tensioner
During a frontal collision, the seat belts on the front seats
are retracted automatically. The seat belts for the occupants in the front seats are equipped with belt
tensioners. Sensors will only trigger the belt tensioners during severe head-
on, lateral and rear collisions, and only if the seat belt is actually being
worn. This retracts and tightens the seat belts, reducing the forward motion
of the occupants.
The seat belt tensioner can be triggered only once.
The seat belt tensioners 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. 

29
Seat belts
Note
● If the seat belt tensioners are triggered, a fine dust is produced. This is
normal and it is not an indication of fire in the vehicle.
● The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. Specialised workshops are famili-
ar with these regulations, which are also available to you. 
Service and disposal of belt tensioners
The belt tensioners are components of the seat belts that are installed in
the seats of your vehicle. If you work on the belt tensioners or remove and
install parts of the system when performing other repair work, the seat belt
may be damaged. The consequence may be that, in the event of an acci-
dent, the belt tensioners function incorrectly or not at all.
So that the effectiveness of the seat belt tensioner is not reduced and that
removed parts do not cause any injuries or environmental pollution, regula-
tions, which are known to the specialised workshops, must be observed.
WARNING
● Improper use or repairs not carried out by qualified mechanics in-
crease the risk of severe or fatal injuries. The belt tensioners may fail to
trigger or may trigger in the wrong circumstances.
● Never attempt to repair, adjust, remove or install parts of the belt ten-
sioners or seat belts.
● The seat belt tensioner, seat belt and automatic retractor cannot be
repaired.
WARNING (Continued)
● Any work on the belt tensioners and seat belts, including the removal
and refitting of system parts in conjunction with other repair work, must
be performed by a specialised workshop only.
● The belt tensioners will only provide protection for one accident and
must be changed if they have been activated.

30Airbag system
Airbag system
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 11.
– Adjust the front passenger seat correctly ⇒ page 12.
– Adjust the head restraint correctly ⇒ page 14.
– 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 44. 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 turn the airbag
off, a Technical Service 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 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.
● For those vehicles that do not include a key lock switch to turn the
airbag off, a Technical Service must be consulted.
● 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 44.
– 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.
