Front airbags
Description of front airbags
The airbag system is not a substitute for the seat belts.
Fig. 17 Driver airbag lo-
cated in steering wheel
Fig. 18 Front passenger
airbag located in dash
panel 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 dash panel ⇒ Fig. 18. Air-
bags are identified by the word “AIRBAG”.
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 se-
vere frontal collision ⇒ page 37, Safety notes on the front 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 air-
bags 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 vehicle 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 front airbag system are:
● an electronic control and monitoring system (control unit)
● the two front airbags (airbag with gas generator) for the driver and front
passenger
● a control lamp  in the dash panel
The airbag system operation is monitored electronically. The airbag control
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 control lamp :
● does not light up when the ignition is switched on
● turns off after 4 seconds after the ignition is switched on
● turns off and then lights up again after the ignition is switched on
● lights up or flashes while the vehicle is moving 

Side airbags* Description of side airbags
The airbag system is not a substitute for the seat belts.
Fig. 23 Side airbag in
driver seat
The side airbags are located in the backrest cushions of the driver seat
⇒  Fig. 23 and the front passenger seat as well as in the rear seats*. The lo-
cations are identified by the text “AIRBAG” in the upper region of the backr-
ests.
Together with the seat belts, the side airbag system gives the front seat oc-
cupants additional protection for the upper body in the event of a severe
side collision ⇒ page 41, 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 occupants in a collision, the seat
belts also hold the passengers in the front seats and 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 19, 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 side airbags in the sides of the backrests of the front and rear seats
● a control lamp  in the dash panel
The airbag system operation is monitored electronically. The airbag control
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 airbags will not work if the sensors do
not correctly measure the pressure increase on the interior of the doors,
due to air escaping through the areas with holes or openings in the door
panel.
● Never drive the vehicle if the interior panels have been removed.
● Never drive if the interior door panels have been removed or if the
panels have not been correctly fitted. 

Airbag system
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 side airbag system
If airbags are used correctly, they can considerably reduce
the 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 a greater risk of injury
if the side airbag system is triggered in an accident.
● 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.
● Occupants of the outer seats must never carry any objects or pets in
the deployment space between them and the 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 im-
pair 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.
WARNING (Continued)
● Under no circumstances should protective covers be fitted over seats
with side airbags unless the covers have been approved for use in your
vehicle. Because the airbag deploys from the side of the backrest, the
use of conventional seat covers would obstruct the side airbag, seriously
reducing the airbag's effectiveness.
● Any damage to the original seat upholstery or around the seams of
the side airbag units must be repaired immediately by a specialised
workshop.
● The airbags provide protection for just one accident; replace them
once they have deployed.
● When children assume an incorrect sitting position, they expose
themselves 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.
● 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 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 operation of the side
and head airbags neither the doors nor the door panels should be modi-
fied 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 done in a specialised workshop.

Airbag system
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 airbag covers the side windows and door pillars.
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 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 curtain airbag must be disabled in those vehi-
cles fitted with a screen dividing the interior of the vehicle. See a Techni-
cal Service to make this adjustment.
WARNING (Continued)
● There must be no other persons, animals or objects between the oc-
cupants of the outer seats and the deployment space of the curtain air-
bags so that the curtain airbag can deploy without restriction and pro-
vide 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.
● 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 operation of the side
and head airbags neither the doors nor the door panels should be modi-
fied 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 done in a specialised workshop.

Deactivating airbags
Deactivating airbags
The deactivation of airbags corresponds only to certain cases, i.e. if:
● a child seat is required in the front passenger seat with the child facing
in the opposite direction to the direction of travel (in some countries, due to
divergent legal requirements, facing in the direction of travel) ⇒ page 49;
● despite the driver seat being in the correct position, a minimum dis-
tance of 25 cm cannot be maintained between the centre of the steering
wheel and the driver's torso.
● installation of special devices is required in the steering wheel area due
to a physical disability.
● if you have special seats installed (e.g. an orthopaedic seat without side
airbag).
The front passenger front airbag can be disabled using the switch
⇒ page 45.
We recommend that you contact an authorised SEAT dealer for the disabling
of other airbags.
Airbag system control
The airbag system availability is controlled electronically, regardless of
whether an airbag is disabled.
If an airbag was disabled using a diagnostics system:
● the airbag system warning lamp  lights up after switching on the igni-
tion for about 4 seconds, and then flashes for about 12 seconds If the airbag has been disabled with the airbag switch on the side of the
dash panel:
●
the airbag control lamp  will light up for about 4 seconds after the ig-
nition is switched on.
● The airbag is disabled, signalled with the warning lamp   which
lights up with the word      placed in the centre part of the
dash panel ⇒ Fig. 26.
Note
● Respect the current legislation in your country regarding the deactiva-
tion of airbags
● At your authorised SEAT dealer you can find information on which vehi-
cle airbags can be deactivated. 
