Airbag system
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.
● In a side-on collision the side airbags will
not work if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been removed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or covered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach 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 bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered.
● 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 con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the seams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval and installation of the airbag compo-
nents 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. Head-protection airbags*
Fig. 72
Location of head-protection airbags. The head-protection airbags are located on
both sides in the interior above the doors
››› Fig. 72 and are identified with the text
“AIRB AG”.
In c
onjunction with the seat belts, the head-
protection airbag system gives the vehicle
occupants additional protection for the head
and upper body in the event of a severe side
collision ››› .
WARNING
● In order for the head-protection airbags to
provide their maximum protection, the pre-
scribed sitting position must always be main-
tained with seat belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disabled in those vehicles fitted with a
screen dividing the interior of the vehicle. » 53

●
There must be no other persons, animals or
objects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction 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 win-
dows
● 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 hang-
ers.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the head-protection airbag
system or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem 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 curtain 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 done in a special-
ised workshop.

We recommend that you contact an author-
ised SEAT dealer for the disabling of other air-
bags.
Airbag system control
The airbag system availability is controlled
electronically, regardless of whether an air-
bag is disabled.
If an airbag was disabled using a diagnostics
system:
● the airbag system warning lamp  illumi-
nates after switching on the ignition for
about 4 seconds, and then flashes for about
12 seconds. If the airbag has been disabled with the air-
bag switch on the side of the dash panel:
●
the airbag control lamp  will illuminate
for about
4 seconds after the ignition is
switched on,
● The airbag is disabled, signalled with the
warning lamp
  which lights up with the
word      placed in the cen-
tre part of the dash panel ››› Fig. 74. WARNING
In the event of a fault in the airbag system,
the airbag may not trigger correctly, may fail
to trigger or may even trigger unexpectedly,
leading to severe or fatal injuries.
● Have the airbag system checked immedi-
ately by a specialised workshop.
● Never mount a child seat in the front pas-
senger seat or remove the mounted child
seat! The front passenger front airbag may
deploy during an accident in spite of the
fault. CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
● Follow the current legislation in your coun-
try regarding the disabling of airbags. ●
At your authorised SEAT dealer you can find

Please go immediately to an Official Service. WARNING
● The driver of the vehicle is responsible for
disabling or switching on the airbag.
● Always switch off the ignition before disa-
bling the front passenger airbag! Failure to do
so could result in a fault in the airbag deacti-
vation system.
● Never leave the key in the airbag disabling
switch as it could get damaged or enable or
disable the airbag during driving.
● If the   (airbag disabled) control lamp

the system immediately checked by an Offi-
cial Service. Transporting children safety
Safety for children Introduction For safety reasons, as we have learned from
accident statistics, we recommend that chil-
dren under 12 years of age travel in the rear
seats. Depending on their age, height and
weight, children travelling in rear seats must
use a child seat or a seat belt. For safety rea-
sons, the child seat should be installed in the
rear seat, behind the front passenger seat or
in the centre back seat.
The physical laws involved and the forces
acting in a collision apply also to children
››› page 45 . But unlike adults, children do not
h av
e fully developed muscle and bone struc-
tures. This means that children are subject to
a greater risk of injury.
To reduce the risk of injuries, children must
always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety prod-
ucts from the SEAT Original Accessories Pro-
gramme, which includes systems for all ages
made by “Peke” (not for all countries).
These systems have been especially de-
signed and approved, complying with the
ECE-R44. regulation.

Operation
Engine cold
If only the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 203. CAUTION
● To ensure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
››› page 77 as a guide. ●
Additional lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the cooling air when the vehicle is
moving. If the spoiler is damaged this can re-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Gas

Problem:
If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure that there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driver and for other road users. If
necessary, switch on the hazard warning
