Te c h n i c a l D a t a
The front airbag system will not be triggered if:
•
if the ignition is switched off,
•
during a minor frontal collision,
•
during a minor side collision,
•
during a rear-end collision,
•
or if the vehicle rolls.
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 should occur in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise there is a danger that
during a frontal collision, the system may fail to trigger, or not trigger
correctly.
Function of front 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. Once the impact has been
absorbed, the airbag deflates sufficiently for the front occupants to see
forward.

Safety notes on 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 maintain 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.
•
If you are not wearing a seat belt or if you lean forward or to the side or
assume an incorrect sitting position, the risk of injury is increased
substantially. 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”.
•
Occupants sitting in the front of the vehicle must never carry any
objects or pets in the deployment sp ace between them and the airbags, or
allow children or other passengers to travel in this position.
•
The airbags provide protection for one accident only, if they have been
deployed they must be replaced.
•
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.
Side airbags*Description of side airbags
The airbag system is not a substitute for the seat belts.The side airbags are located in the backrest cushions of the driver seat
⇒ fig. 21 and the front passenger seat as well as in the outer rear seats. The
locations are identified by the text “AIRBAG” in the upper region of the back-
rests.
In conjunction with the seat belts, the side airbag system gives the front seat
occupants 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 occupan ts in a collision, the seat belts also

Function of side airbags
Inflated airbags can reduce the risk of head or chest injury in
many side impact collisions.In some side collisions the side airbag is triggered on the impact side of the
vehicle ⇒fig. 22.
In ce rtain types of accident, the front curta in and side airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within fractions of a second). A fine dust
may develop when the airbag deploys. This is normal and is no indication
that there was a 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. 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.

Curtain airbagsDescription of curtain airbags
The airbag system is not a substitute for the seat belts.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, th e 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
curtain airbag system”.
The airbag system is not a substitute for seat belts, but 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. For this
reason, 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, “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
passenger and passengers on the rear seats,
•
a warning lamp
 in the dash panel insert ⇒page 31.
The functionality of the airbag system is monitored electronically.
The curtain airbag system will not be triggered
•
if the ignition is switched off,

Tips and Maintenance
Te c h n i c a l D a t a
•
There must be no other persons, animals or objects between the occu-
pants of the outer seats and the deployment space of the curtain airbags
so that the curtain airbag can deploy without restriction and provide 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 191, “Accessories, parts replacement and modifica-
tions”.
•
The built-in coat hooks should be used only for lightweight clothing. Do
not leave any heavy or sharp-edged obje cts in the pockets. When using the
coat hooks, do not hang th e clothes on coat hangers.
•
The airbags provide protection for one accident only, if they have been
deployed they must be replaced.
•
Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lining)
should only be performed by a qualified workshop. Otherwise, a fault may
be introduced into the operation of the airbag system.
•
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 damaged in any way,
this may affect the correct working of the system. All work carried out on
the front door must be made in a qualified workshop.WARNING (continued)

Tips and Maintenance
Te c h n i c a l D a t a
– Check that the warning lamp in the dash panel does ⇒page 44,
fig. 26 not light up when the ignition is switched on ⇒.
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 safety”.
•
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 (or rear-facing) on the front
passenger seat unless the front passenger airbag has been disabled. This
represents a risk of fatal injuries to th e child! However, if it is necessary in
exceptional circumstances 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, this will create a danger that
in case of an accident, the airbag do es not deploy properly or does not
deploy at all.
•
When the passenger airbag is deactivated, if the warning lamp is not
continuously lit up when the front passenger airbag is disabled, there may
be a fault in the airbag system:
−Have the airbag system inspected immediately by a qualified work-
shop.
− Do not use a child seat on the front passenger seat! The front
passenger 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 inju-
ries. −
It is not certain whether the fron t passenger airbag will deploy
during an accident! Inform your passengers of this.
•
When using the ignition key to activate / deactivate the passenger front
airbag, only the passenger front airbag will be activated / deactivated. The
side airbag and head airbag on the passenger side will remain active.WARNING (continued)

Safety notes on using child seats
Proper use of child seats substantially reduces the risk of
injury in an accident!As the driver, you are responsible for any children you transport in
your vehicle.
– Protect your children by properly using appropriate child seats
⇒page 48.
– Always ensure that the belt webbing is properly positioned according to the instructions prov ided by the manufacturer of the
child seat.
– When travelling, do not allow children to distract you from traffic.
– Take breaks regularly during long trips. Take a break at least every two hours.
WARNING
•
Never install a child seat facing backwards (or rear-facing) on the front
passenger seat unless the front passenger airbag has been disabled. This
represents a risk of fatal injuries to the child! However, if it is necessary, in
exceptional cases, to transport a child in the front passenger seat, the front
passenger airbag must always be disabled ⇒page 44, “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 turn the
airbag off, an Authorised Service Centre must be consulted.
•
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 potentially
fatal injuries to the child!
•
Never allow a child to be transported in a vehicle without being properly
secured, or to stand up or kneel on a seat while travelling. In an accident,
the child could be flung through the vehicle, causing possibly fatal injuries
to themselves and other occupants.
•
If children assume an improper sitting position when the car is moving,
they expose themselves to greater risk of injury during a sudden braking
manoeuvre or in an accident. This is particularly the case if the child is trav-
elling on the front passenger seat and the airbag system is triggered in an
accident; this could have consequences including serious injury or death.
•
A suitable child seat can protect your child!
•
Never leave a child unsupervised in a child seat or alone in the vehicle.
•
Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
•
Children who are less than 1.5 metres tall must not wear a normal seat
belt without a child restraint system, as this could cause injuries to the
abdominal and neck areas during a sudden braking manoeuvre or in an
accident.
•
Do not allow the belt webbing to become twisted or jammed, or to rub
on any sharp edges.
•
Incorrectly worn seat belts can cause injuries even in a minor collision
or sudden braking manoeuvres.
•
The seat belt provides maximum protection only when the belt web is
properly positioned ⇒page 24, “Seat belts”.
•
Only one child may occupy a child seat ⇒page 48, “Child seats”.WARNING (continued)
