•
Never drive the vehicle if the loudspeakers in the door panels have
been removed, unless the holes left by the loudspeakers have been
correctly closed.
•
Always check that the openings are cl osed 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 qualified author-
ised 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 should occur in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise there is a danger that
during a side collision, the system may fail to trigger, or not trigger
correctly.
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 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.
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. Th is 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 help to reduce the risk of injury to the upper body.

risk of injury in side impact collisions.
WARNING
•
If you do not wear a seat belt, if you lean forward, or are not seated
correctly while the vehicle is in motion , you are at greater risk of injury
should the side airbag system be triggered in an accident.
•
In order for the side airbags to provide their maximum protection, the
prescribed sitting position must alwa ys be maintained with seat belt
fasten while travelling.
•
Occupants of the outer seats must never carry any objects or pets in the
deployment space between them and th e airbags, or allow children or
other passengers to travel in this position. It is also important not to attach
any accessories (such as cup holders) to the doors. This would impair the
protection offered by the side airbags.
•
The built-in coat hooks should be used only for lightweight clothing. Do
not leave any heavy or sharp-edged objects in the pockets.
•
Great forces, such as hard blows or kicks, must not be exerted upon the
backrest bolster because the system may be damaged. In this case the side
airbags would not be triggered.
•
Under no circumstances should protective covers be fitted over the
driver seat or front passenger seat unless the covers have been expressly
approved for use in your vehicle. Because the airbag deploys from the side
of the backrest, the use of non-approved seat covers would obstruct the
side airbag seriously reducing the airbag's effectiveness ⇒page 186,
“Accessories, parts replacement and modifications”.
•
Any damage to the original seat uphol stery or around the seams of the
side airbag units must be repaired immediately by a qualified workshop.
•
The airbags provide protection for one accident only, if they have been
deployed they must be replaced.
•
When children assume an incorrect sitting position, they expose them-
selves to an increased risk of injury in the event of an accident. This is
particularly the case if the child is travelling on the front passenger seat
and the airbag system is triggered in an accident; this could have critical
consequences including serious injury or death ⇒page 47, “Child safety”.
•
Any work on the side airbag system or removal and installation of the
airbag components for other repairs (such as removal of the front seat)
should only be performed by a qualif ied 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)

Airbag system
42Curtain 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 43, “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 ga s 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 you use airbags correctly, they can considerably reduce the
risk of injury in many kinds of accident.
WARNING
•
In order for the curtain airbags to provide their maximum protection,
the prescribed sitting position must al ways be maintained with seat belt
fasten 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 186, “Accessories, parts replacement and modifica-
tions”.

Deactivating 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. All the other airbags in the vehicle
remain functional.
Disabling front passenger airbag
– Switch off ignition.
– Turn the ignition switch in the key operated switch in the glove box to the position OFF ⇒ fig. 25 .
– Check that the warning lamp “PASSENGER AIRBAG OFF” in the dash panel ⇒fig. 26 remains lit ⇒when the ignition is
switched on.
Enabling front passenger airbag
– Switch off ignition.
– Turn the ignition switch in the key-operated switch in the glove box to the position ON ⇒ fig. 25 .

– Check that the warning lamp “PASSENGER AIRBAG OFF” in the dash panel does ⇒ page 45, fig. 26 not light up when the igni-
tion 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-fac ing child seat in ex ception
al cases ⇒ pag
e 47, “Child saf
ety”.
•
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 rear-facing child seat on the front passenger seat unless
the front passenger airbag has been disabled. Risk of potentially fatal inju-
ries 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.
•
If the passenger airbag is disabled the monitor indicator PASSENGER
AIRBAG OFF does not remain lit, th e airbag system may be faulty:
− 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 front 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)

Child 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 be 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 principles involved and the forces acting in a collision apply to
children just as much as adults ⇒page 21, “Why wear seat belts?”.
But unlike adults, children do not have fully developed muscle and bone
structures. 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”
1).
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 48, “Safety notes on using child seats”. We recommend that you include the manufacturer's directions for child seat
use in the vehicle wallet and always keep them in the vehicle.

Child safety
48Safety 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 49.
– 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 rear-facing child seat on the front passenger seat unless
the front passenger airbag has been disabled. Risk of potentially fatal inju-
ries to the child! If it is necessary, in exceptional circumstances, to trans-
port a child on the front passenger seat, always disable the front passenger
airbag ⇒ page 45, “Deactivating airbags*”.
•
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 thrown through the vehicle, causing possibly fatal inju-
ries 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 pa rticularly 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 prot ection only when the belt web is
properly positioned ⇒ page 24, “Seat belts”.
•
Only one child may occupy a child seat ⇒page 49, “Child seats”.WARNING (continued)
