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 22.

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 trigger the belt tensioners 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 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.
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.
● 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.

● 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. 

Airbag system
that the airbag system can only help to protect you if you are wearing your
seat belt and wearing it properly.
Remember too that airbags will deploy only once and only in certain kinds
of accidents - your seat belts are always there to offer protection in those
accidents in which airbags are not supposed to deploy or when they have
already deployed, for example when your vehicle strikes or is struck by an-
other after the first collision.
This is just one of the reasons why an airbag is not a substitute for the seat
belt. The airbag system works most effectively when used with the seat
belts. Therefore, always wear your seat belts correctly.
It is important to remember that while the airbag system is designed to re-
duce the possibility 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 on the instrument panel
The knee airbag system will not be triggered:
● if the ignition is switched 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 (hazard warning lights/turn signals
illuminated) ⇒ page 67.
WARNING
● Seat 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 Technical Service. The
airbag may not work properly when the vehicle acceleration in a side col-
lision is high enough to deploy the airbag. See also ⇒ page 67.

How knee airbags work
The risk of injury to the leg area is reduced by fully deployed
knee airbags.
Fig. 23 Inflated airbags
protect in a frontal colli-
sion.
The knee airbag system has been designed so that the airbag for the driver
is deployed in certain but not all frontal collisions.
If the front airbag deploys, the knee airbag also deploys in severe frontal
collisions. 

Airbag system
Operation of curtain airbags
Fully inflated airbags reduce the risk of head or chest injury
in a side collision.
Fig. 27 Deployed curtain
airbags
During some side collisions the curtain airbag is triggered on the impact
side of the vehicle ⇒ Fig. 27.
In certain types of accident the front, side and curtain airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas. In the
process, the curtain airbag covers the side windows and door pillars.
The airbags deploy extremely rapidly, within thousandths of a second, to
provide additional protection in the event of an accident. A fine dust may
develop when the airbag deploys. This is normal and it is not an indication
of fire in the vehicle.
The fully deployed airbags cushion the movement of the front occupants
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.

Safety notes on the operation of the curtain airbag system
If you use airbags correctly, they can considerably reduce
the risk of injury in many kinds of accident.
WARNING
● 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.
● For safety reasons, the curtain airbag must be disabled in those vehi-
cles fitted with a screen dividing the interior of the vehicle. See a Techni-
cal Service to make this adjustment.
● There must be no other persons, animals or objects between the oc-
cupants of the outer seats and the deployment space of the curtain air-
bags so that the curtain airbag can deploy without restriction and pro-
vide the greatest possible protection. Therefore, sun blinds which have
not been expressly approved for use in your vehicle may not be attached
to the side windows ⇒ page 230, Accessories, replacement of parts and
modifications.
● The built-in coat hooks should be used only for lightweight clothing.
Do not leave any heavy or sharp-edged objects in the pockets. Please, do
not hang the clothes on coat hangers.
● The airbags provide protection for just one accident; replace them
once they have deployed. 

48Child safety
WARNING
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger front airbag has been disabled. Risk of
potentially fatal injuries to the child! However, if it is necessary, in excep-
tional cases, to transport a child in the front passenger seat, the front
passenger front airbag must always be disabled ⇒ page 45, Deactivating
airbags. If the passenger seat has a height adjustment option, move it to
the highest position.
● For those vehicles that do not include a key lock switch to deactivate
the airbag, the vehicle must be taken to a Technical Service.
● All vehicle occupants, especially children, must assume the proper
sitting position and be properly belted in while travelling.
● Never hold children or babies on your lap, this can result in potential-
ly fatal injuries to the child!
● Never allow a child to be transported in a vehicle without being prop-
erly secured, or to stand up or kneel on a seat while travelling. In an acci-
dent, the child could be flung through the vehicle, causing possibly fatal
injuries to themselves and to the other vehicle occupants.
● If children assume an improper sitting position when the vehicle is
moving, they expose themselves to greater risk of injury in the event of a
sudden braking manoeuvre or in an accident. This is particularly impor-
tant if the child is travelling on the front passenger seat and the airbag
system is triggered in an accident; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave an unsupervised child alone on a child seat or in the vehi-
cle.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.WARNING (Continued)
● Children who are less than 1.5 metres tall must not wear a normal
seat belt without a child seat, as this could cause injuries to the abdomi-
nal and neck areas during a sudden braking manoeuvre or in an accident.
● Do not allow the seat belt to become twisted or jammed, or to rub on
any sharp edges.
● Incorrectly worn seat belts can cause injuries even in a minor colli-
sion or in sudden braking manoeuvres.
● The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒ page 24, Seat belts.
● Only one child may occupy a child seat ⇒ page 49, Child seats.
