Airbag system
32Front airbagsDescription of front airbags
The airbag system is not a substitute for the seat belts.
The front airbag for the driver is located in the steering wheel ⇒fig. 17 and
the airbag for the front passenger is located in the instrument panel
⇒ fig. 18 . Airbags are identified by the word “AIRBAG”. In the driver's side,
the knee airbag* is found in the front passenger's footwell, under the instru-
ment panel.
In conjunction with the seat belts, the front airbag system gives the front
occupants additional protection for the head and chest in the event of a
severe frontal collision ⇒page 35, “Safety notes on the frontal airbag
system”.
In addition to their normal function of restraining the occupants, the seat
belts also hold the driver and front passenger in a position where the airbags
can provide maximum protection in a frontal collision.
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 th e 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 18,
“Brief introduction”.

The main parts of the front airbag system are:
•
an electronic control and monitoring system (control unit),
•
the two front airbags (ai
rbag with gas generator) for the driver and front
passenger,
•
a knee airbag* for the driver,
•
a warning lamp
 in the dash panel insert ⇒page 29.
The airbag system operation is monito red electronically. The airbag warning
lamp will light up for a few seconds every time the ignition is switched on
(self-diagnosis).
There is a fault in the system if the warning lamp

•
does not light up when the ignition is switched on ⇒page 29
•
after the ignition is switched on, it turns off after 4 seconds,
•
it turns off and then lights up again after the ignition is switched on,
•
lights up or flashes while the car is moving.
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 occured in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise, during a frontal collision
the system may fail to trigger, or not trigger correctly.
Operation of frontal 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. After the collision, the
airbag deflates sufficiently for the front occupants to see forward.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (withi n thousandth of a second). A fine dust

driver's and front passenger's airbags are triggered ⇒fig. 20. The airbag
covers remain connected to the steering wheel or the dash panel.

Safety notes on the frontal 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 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, if you lean forward or to the side while
travelling or assume an incorrect sitting position, there is a substantially
increased risk of injury. 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”.
•
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.
Knee airbagDescription of the knee airbag
The airbag system provides additional protection to the front
seat passengers if they are properly secured.The airbag for the driver is located in the instrument panel underneath the
steering wheel ⇒ fig. 21.
The knee airbag offers additional protection to the driver’s knees and upper
and lower thigh areas as a supplement to the safety belts.
If the front airbags deploy, the knee airbag also deploys in frontal collisions
above a certain severity ⇒page 33.
Besides their normal safety function, safety belts work to help keep the driver
in position in case of a frontal collision so that the airbags can provide protec-
tion.

Airbag system
36The airbag system is not a substitute for your seat belts. Rather, it is part of
the overall occupant restraint system in your vehicle. Always remember that
the airbag system can only help to protect you if you are wearing your safety
belt and wearing it properly.
Remember too, airbags will deploy only once and only in certain kinds of acci-
dents - your safety belts are always there to offer protection in those acci-
dents in which airbags are not supposed to deploy or when they have already
deployed, for example when your vehicle strikes or is struck by another after
the first collision.
This is just one of the reasons why an airbag is not a substitute for the safety
belt. The airbag system works most effectively when used with the safety
belts. Therefore, always wear your safety belts correctly.
It is important to remember that while the supplemental airbag system is
designed to reduce the likelihood of serious injuries, other injuries, for
example, swelling, bruising, and minor ab rasions can also be associated with
airbags.
The knee airbag system basically consists of:•
The electronic control module
•
One inflatable airbag (airbag an d gas generator) for the driver
•
airbag indicator light in the instrument panel
The knee airbag system will not deploy:
•
when the ignition is turned off
•
in front-end 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 (warning/indicator light illuminated)
⇒ page 65.
WARNING
•
Safety belts and the airbag system can only provide protection when
occupants are in the proper seating position.
•
If the airbag indicator light comes when the vehicle is being used, have
the system inspected immediately by your authorized SEAT dealer. The
airbag may not work properly when the vehicle acceleration in a side colli-
sion is high enough to deploy the airbag. See also ⇒page 65.
How knee airbags work
The risk of injury to the leg area is reduced by fully deployed
knee airbags.The knee airbag system has been designed so that the airbag for the driver is
deployed in certain but no t all frontal collisions.

If the front airbag deploys, the knee airbag also deploys in frontal collisions
above a certain severity.
When the system is deployed, the airbag starts to fill with a propellant gas,
and inflates between the lower part of the instrument panel and the driver
⇒
page 36, fig. 22 .
Although they are not a soft pillow, they can “cushion” the impact and in this
way they can help to reduce the risk of injury to the lower extremities.
All this takes place instantaneously, so fast that many people don't even
realize that the airbags have deployed. The airbags also inflate with a great
deal of force and it is important for occupant safety that nothing should be in
their way when they deploy.
Fully inflated airbags in combination with properly worn safety belts slow
down and limit the occupant's forward movement and help to reduce the
risk.
Important safety notes on the knee airbag system
Airbags are only supplemental restraints.Always wear safety belts correctly and ride in a proper seating position. There
is a lot that you and your passengers must know and do to help the safety
belts and airbags to provide supplemental protection.
WARNING
An inflating knee airbag can cause serious injury. Wearing safety belts
incorrectly and improper seating posi tions increase the risk of serious
personal injury and death whenever a vehicle is being used.•
The airbag system cannot protect you properly if you are seated too
close to any of the airbag locations. Wh en adjusting their seat positions, it is important that the driver keep
their upper bodies and knees at the
following minimum safe distances:
−25 cm between the chest and the steering wheel/instrument panel.
− 10 cm between the knees and the lowe r part of the instrument panel.
•
The risk of personal injury increases if you lean forward or to the side,
or if the seat is improperly positioned and you are not wearing your safety
belt. The risk increases even more should the airbag deploy.
•
Always make sure that the knee airb ag can inflate without interference.
Objects between yourself and the airbag can increase the risk of injury in
an accident by interfering with the way the airbag deploys or by being
pushed into you as the airbag deploys.
−No objects of any kind should be carried in the footwell area in front
of the driver’s seat. Bulky objects (shopping bags, for example) can
hamper or prevent proper deployment of the airbag. Small objects can
be thrown through the vehicle if the airbag deploys and injure you or
your passengers.
•
Make sure there are no cracks, deep scratches or other damage in the
area of the instrument panel where the knee airbag is located.
•
If children are incorrectly seated, their risk of injury increases in the
case of an accident ⇒page 46.WARNING (continued)

Airbag system
38Side airbags*Description of side airbags
The airbag system is not a substitute for the seat belts.The front side airbags are located in the driver's seat and front passenger's
seat backrests ⇒fig. 23 . The rear side airbags are located in the rear wheel
housing lining. The locations are identified by the text “AIRBAG” in the upper
region of the backrests and in the rear wheel housing lining.
Together with the seat belts, the side airbag system gives the front seat occu-
pants additional protection for the upper body in the event of a severe side
collision ⇒page 40, “Safety notes on the op eration 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 occupants in a collision, the seat belts also hold the passengers in the front seats an
d the outer rear seats in a position
where the side airbags can provide maximum protection.
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. 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 18, “Brief introduction”.
The side airbag system will not be triggered if:
•
the ignition is switched off,
•
there is a minor side collision,
•
there is a frontal collision,
•
there is a rear-end collision,
•
the vehicle turns over.
The main parts of the airbag system are:
•
an electronic control and monitoring system (control unit),
•
The front side airbags in the backrests of the front seats and the rear side
airbags in the lining of the rear wheel housing.
•
a warning lamp
 in the dash panel insert ⇒ page 29.
The airbag system operation is monitored electronically. The airbag warning
lamp will light up for approx. 4 seconds every time the ignition is switched on
(self-diagnosis).
WARNING
•
In a side-on collision, the side airb ags will not work, if the sensors do
not correctly measure the pressure incr ease on the interior of the doors,
due to air escaping through the areas wi th holes or openings in the door
panel.
•
Never drive the vehicle if the interior panels have been removed.
