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, 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 40, “Safety notes on the operation of the
curtain 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 ga s generator) for the driver, front
passenger and passengers on the rear seats,•a warning lamp
 in the dash panel insert ⇒page 30.
The airbag system operation is monitored electronically.
The curtain airbag system will not be triggered

If a fault has occurred in the airbag system, have the system checked imme-
diately by a qualified workshop. Otherwise there is a danger that during a
collision, the system may fail to trigger, or not trigger correctly.Function of curtain airbags
Fully inflated airbags reduce the risk of head or chest injury in
a side collision.
During some side collisions the curtain airbag is triggered on the impact side
of the vehicle ⇒ fig. 24.
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 bag covers the side windows and door pillars.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust
may develop when the airbag deploys. This is normal and it is not an indica-
tion 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 head air bag must be disconnected in those
vehicles fitted with a passenger compartment separation screen. See an
Authorised Service Centre to make this adjustment.

•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 206, “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 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 lining)
should only be performed by a qualified 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 damaged, the airbag
system may not work correctly. All work carried out on the front door must
be made in a qualified workshop.WARNING (continued)

42Deactivating airbags*Disabling front passenger airbag
If you fit a rear-facing child seat to the front passenger seat,
the front passenger airbag must be de-activated.
When the passenger airbag is deactivated, this means that only the
frontal airbag is deactivated. Al l the other airbags in the vehicle
remain functional.
Disabling front passenger airbag
– Switch the ignition off.
– Turn the ignition switch in the key operated switch in the glove
box to the position OFF ⇒ fig. 25 .
– Check that the warning lamp “OFF” on the instrument panel ⇒fig. 26 remains lit when the ignition is switched on ⇒.
Enabling front passenger airbag
– Switch the ignition off.
– Turn the ignition switch in the key-operated switch in the glove
box to the position ON ⇒ fig. 25 .

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 the 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 does not deploy properly or does not
deploy at all.•When the passenger airbag is deactivated, if the warning lamp AIRBAG
OFF 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 predictable whether the front passenger airbag will deploy
during an accident! Warn all 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)

Child safety
44Child safetyBrief introductionIntroduction
Statistics show that children are generally safer on the rear
seat than on the front passenger seat.We recommend that children under 12 years of age are transported on the
rear seats. Children travelling on the rear seat must use a child restraint
system or the seat belts provided, depending on their age, height and
weight. For safety reasons, the child restraint system should be installed in
the centre of the rear seat or behind the front passenger's seat.
The physical laws involved and the forces acting in a collision apply also to
children. ⇒page 20, “Why wear seat belts?”.
But unlike adults, children do not have muscle and bone structures fully
developed. This means that children are subject to a greater risk of injury.
To reduce this risk, children must always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety products from the SEAT Genuine Acces-
sories Program including systems for all ages made by “Peke”
2).
These systems have been especially designed and approved, complying with
the ECE-R44. regulation.
Follow the manufacturer's instructions and observe any statutory require-
ments when installing and using child seats. Always read and observe
⇒ page 45. We recommend you to include together with the on-board documentation,
the manufacturer's Child Seat instructions manual.

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 46.
– Always ensure that the belt webbing is properly positioned according to the instructions provided 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
could lead to a risk of potentially 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 42,
“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 to the other passengers.•If children assume an improper sitting position when the car is moving,
they expose themselves to greater risk of injury in the event of sudden
braking manoeuvre or in an accident. This is particularly important if the
child is travelling on the front passenger seat and the airbag system is trig-
gered 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
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 in sudden braking manoeuvres.•The seat belt provides maximum protection only when the belt web is
properly positioned ⇒page 23, “Seat belts”.•Only one child may occupy a child seat ⇒page 46, “Child seats”.WARNING (continued)
