Safety
See your technical service to make this ad-
justment.
●
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.

position, a minimum distance of 25 cm can-
not 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 dis-
ability,
● if you have special seats installed (e.g. an
orthopaedic seat without side airbags).
The front passenger front airbag can be disa-
bled using the switch ››› page 55.
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
information on which vehicle airbags can be
disabled. Front passenger front airbag switch

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

shes, the front passenger front airbag will
not trigger in the event of an accident! Have
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.

The essentials

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

reaches the reserve mark, the lower diode
lights up in red and the control lamp  ap-
pears ››› page 66. When the fuel level is very
low

, the lower diode flashes in red. The yellow control lamp 
lights up when the
reserve level has been reached.
The green warning lamp 
lights up when the
vehicle is running in natural gas operating
mode.
The green warning lamp 
switches off when
the natural gas is exhausted. The engine
changes to operate with petrol.
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.

this way the unburned fuel can reach the ex-
haust system, which could cause the catalytic
converter to overheat resulting in damage. Control lamps

The c ontr

ol and warning lamps are indicators
of warnings, ››› , faults
››› or certain func-
tions. Some control and warning lamps come
on when the ignition is switched on, and
switch off when the engine starts running, or
while driving. Depending on the model, additional text
messages may be viewed on the instrument
panel display. These may be purely informa-
tive or they may be advising of the need for
action

g upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard. WARNING
If the warning lamps and messages are ignor-
ed, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
messages.
● 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
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and allow it to cool. ●
In any vehicle, the engine compartment is a
hazardous area and could cause severe inju-
ries ››› page 198. CAUTION
Failure to heed the control lamps and text
messages when they appear may result in
