The desired temperature for the interior cannot be lower than that of the ex-
terior air temperature, as the heating and fresh air system cannot cool or de-
humidify the air.
Setting for conditions of optimal visibility
● Set the fan ⇒ Fig. 105 2
to setting 1 or 2.
● Turn the temperature control ⇒ Fig. 105 1 to the centre position.
● Open and direct the air outlets in the dash panel ⇒ page 169.

168Air conditioning
The air conditioning operates most effectively with the windows closed.
However, if the vehicle has heated up after standing in the sun for some
time, the air inside can be cooled more quickly by opening the windows
briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
● Disable air recirculation mode ⇒ page 169.
● Set the fan to the required setting.
● Turn the temperature control to the centre position.
● Open and direct the air outlets in the dash panel ⇒ page 169.
● Turn the air distribution control to the defrost position.
● Press the AC
button to turn on cooling. The button will light up.
The cooling system does not switch on
If the air conditioning system cannot be switched on, this may be caused by
the following: ●
The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than approximately +2 °C (+36 °F).
● The air conditioner compressor has been temporarily switched off be-
cause the engine coolant temperature is too high.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation
can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak!Note
After starting it, any residual humidity in the air conditioner could mist over
the windscreen. Switch on the defrost function as soon as possible to clear
the windscreen of condensation. 

Introduction
The fuel tank flap is on the rear right of the vehicle.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Fuel ⇒ page 177
● Working in the engine compartment ⇒ page 180
WARNING
Refuelling or handling fuel carelessly can cause an explosion or fire re-
sulting in serious burns and injuries.
● Always make sure that you correctly close the fuel cap to avoid evap-
oration and fuel spillage.
● Fuels are highly explosive and inflammable substances that can
cause serious burns and injuries.
● Fuel could leak out or be spilt if the engine is not switched off or if the
filler fuel nozzle is not fully inserted into the tank filler neck when refuel-
ling. This could lead to a fire, explosion and severe injuries.
● When refuelling, turn off the engine and turn off the ignition for safe-
ty reasons.
● Always turn off mobile telephones, radio apparatus and other radio
wave emitting equipment before refuelling. Electromagnetic waves could
cause sparks and lead to a fire.
WARNING (Continued)
● Never enter the vehicle while refuelling. If it is absolutely necessary
to enter the vehicle, close the door and touch a metal surface before
touching the filler nozzle again. This will prevent the generation of static
electricity. Sparks could cause a fire when refuelling.
● Never handle fuel close to open flames, sparks or objects with slow
combustion (e.g. cigarettes).
● Avoid static electricity and electro-magnetic radiation when refuel-
ling.
● Observe the safety regulations of the service station.
● Never spill fuel on the vehicle or in the luggage compartment.
WARNING
For safety reasons, SEAT does not recommend carrying a spare fuel canis-
ter in the vehicle. Fuel could be spilled and catch fire, above all in case of
an accident and this applies to a full container as well as empty contain-
ers. This could lead to explosions, fires and injuries.
● Observe the following if you exceptionally have to carry fuel in a can-
ister:
–Never place a fuel container, to fill it, inside the vehicle or on the
vehicle, for example, in the luggage compartment. Filling in these cir-
cumstances could create an electrostatic charge and spark that could
ignite fuel fumes.
– Always place the canister on the ground to fill it.
– Insert the fuel nozzle into the neck of the canister as far as possi-
ble. 

nanceIf and whenTechnical specifications

172At the filling station
WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the canister while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
CAUTION
● Always remove any fuel spilled anywhere on the vehicle to avoid dam-
age to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can cause serious engine and fuel
system damage; the resulting malfunctions are not covered by the SEAT
warranty. If you refuel with the wrong type of fuel, never start the engine.
This applies to even the smallest amount of the wrong fuel. Seek specialist
assistance. With the engine running, the composition of the wrong fuel
could significantly damage the fuel system and the engine itself.
For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and
allow a professional to dispose of them. Control lamps and fuel gauge

Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
They will switch off after a few seconds.
In natural gas engines
The warning lamp  lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp  lights up when the vehicle is running in natural gas op-
erating mode. The 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 refuel-
ling, the gas level indicator does 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 techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel supply, the power steering as well as all of the driver assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
CAUTION
● Always pay attention to any lit control lamps and to the corresponding
descriptions and instructions to avoid damage to the vehicle.
● Never run the fuel tank completely dry. An irregular fuel supply may lead
to ignition faults and unburnt fuel could enter the exhaust system. This
could damage the catalytic converter.

Note
● The filling nozzles of natural gas pumps can differ in the way they are
operated. If you are unacquainted with the pump, it is advisable that a
member of staff of the service station performs the refuelling operation.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of a fault in the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. 
