Airbag system
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 specialised workshop. Otherwise, during a frontal colli-
sion the system may fail to trigger, or not trigger correctly.
 Operation of front airbags
Inflated airbags reduce the risk of head or chest injury.
Fig. 19 Inflated front air-
bags
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 de-
ploy 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 to allow visibility.
The airbags deploy extremely rapidly, within thousandths of a second, to
provide additional protection in the event of an accident. A fine dust may 

Safety notes on the front 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 and dash panel. If the minimum
distance is not observed then the airbags do not correctly protect the ve-
hicle 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 sub-
stantially increased risk of injury. This increased risk of injury will be fur-
ther increased if you are struck by an inflating airbag.
● Never let a child travel on the front seat without an appropriate re-
straint system. If the airbag is triggered in an accident, children can sus-
tain 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.

WARNING (Continued)
● Never drive the vehicle if the loudspeakers in the door panels have
been removed, unless the holes left by the loudspeakers have been cor-
rectly 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 specialised
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 occurred in the airbag system, have the system checked
immediately by a specialised workshop. Otherwise, during a side colli-
sion, the system may fail to trigger, or not trigger correctly.
 Operation of side airbags
Inflated airbags can reduce the risk of head or chest injury
in many side impact collisions.
Fig. 22 Illustration of
principle: inflated side
airbags on left side of ve-
hicle
In some side collisions, the side airbag is triggered on the impact side of
the vehicle ⇒ 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.
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 occupants of the
front seats and the outer rear seats and help to reduce the risk of injury to
the upper body. 

Curtain airbags
Description of curtain airbags
The airbag system is not a substitute for the seat belts.
Fig. 23 Location of head airbags on the left side of the
vehicle
The curtain airbags are located on both sides in the interior above the doors
⇒ fig. 23 and are identified with the text “AIRBAG”.
In conjunction with the seat belts, the curtain airbag system gives the occu-
pants additional protection for the head and upper body in the event of a
severe side collision ⇒ page 42, Safety notes on the operation of the cur-
tain airbag system.
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 countries, but also for your safety
⇒ page 19, Brief introduction. The main parts of the curtain airbag system are:
●
an electronic control and monitoring system (control unit)
● the curtain airbags (airbags with gas generator) for the driver, front pas-
senger and passengers on the rear seats,
● a warning lamp  on the instrument panel ⇒ page 32
The airbag system operation is monitored electronically.
The curtain airbag system will not be triggered if:
● the ignition is switched off
● there is a frontal collision
● there is a rear-end collision 

not been expressly approved for use in your vehicle may not be attached
to the side windows ⇒ page 208, Accessories, parts replacement 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.
● Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lin-
ing) should only be performed by a specialised 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 dam-
aged, the airbag system may not work correctly. All work carried out on
the front door must be made in a specialised workshop.

WARNING
● The driver is responsible for the proper position of the key-operated
switch.
● You should deactivate the front passenger airbag only if you have to
use a rear-facing child seat in exceptional cases. ⇒ page 46, Child safe-
ty.
● For those vehicles that do not include a key lock switch to turn the
airbag off, an Authorised Service Centre must be consulted.
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger airbag has been disabled. Otherwise,
there is a risk of death. If under exceptional circumstances it is necessary
to transport a child in a rear-facing child seat on the front passenger
seat, you must always disable the front passenger airbag.
● As soon as the child seat is no longer needed on the front passenger
seat, enable the front passenger airbag again.
● Only deactivate the passenger airbag when the ignition is off, other-
wise a fault may occur in the airbag system, which could cause the airbag
to not deploy properly or not deploy at all.
● When the passenger airbag is deactivated, if the warning lamp AIR-
BAG OFF is not continuously lit up, there may be a fault in the airbag sys-
tem:
–Have the airbag system inspected immediately by a specialised
workshop.
– Do not use a child seat on the front passenger seat! The front pas-
senger airbag could be triggered despite the fact that there is a fault
in the system and, as a result, a child could sustain serious or fatal
injuries.
– It is unpredictable whether the front passenger airbag will deploy
in the event of an accident. Warn all your passengers of this.
● When using the ignition key to activate/deactivate the front passen-
ger airbag, only the front passenger airbag will be activated/deactivated.
The side airbag and head airbag on the passenger side will remain ac-
tive.

Child safety
WARNING
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger airbag has been disabled. This could
lead to a risk of potentially fatal injuries to the child! However, if it is nec-
essary, in exceptional cases, to transport a child in the front passenger
seat, the front passenger airbag must always be disabled ⇒ page 44, De-
activating airbags*. If the passenger seat has a height adjustment op-
tion, move it to the highest position.
● For those vehicles that do not include a key lock switch to disconnect
the airbag, the vehicle must be taken to a Technical Service.
● All passengers, 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 passengers.
● 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 25, Seat belts.
● Only one child may occupy a child seat ⇒ page 48, Child seats.
