Heating and ventilation system user instructions
Temperature
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. 

Air vents
Fig. 107 Dash panel: Air vents
Air vents
Never close the air vents ⇒ Fig. 107 A
completely to ensure heating, cool-
ing and ventilation inside the vehicle.
● To open the air vents press the recess with one slat.
● Change the air direction by turning the slats.
● To close the air vents, fold the slats.
There are additional air vents in the centre of the dash panel and in the foot-
well area.
CAUTION
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicines and other heat-sensitive objects may be damaged
or made unsuitable for use by the air coming from the air vents. Air recirculation
Important
Air recirculation mode prevents the ambient air from entering the interior.
When the outside temperature is very high or very low, selecting manual air
recirculation mode for a short period refreshes or heats the interior more
quickly.
●
Switch off air recirculation mode by turning the air distribution control to
the  ⇒ 
position.
Switching the air recirculation mode on and off 
Switching on: Move the sliding control ⇒ Fig. 106 4
to the right to maxi-
mum.
Switching off: Move the sliding control ⇒ Fig. 106 4
as far left as possible.

170Air conditioning
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required.
CAUTION
Do not smoke when the air recirculation is activated. The smoke taken in
could lie on the cooling system vaporiser and on the dust and pollen filter,
leading to a permanently unpleasant smell. 

204Vehicle care and maintenance
WARNING
Additional underseal or anti-corrosion products could catch fire due to
the high temperatures reached by the exhaust gas system and other en-
gine components.
● Do not apply additional underseal or anti-corrosion products to the
exhaust pipes, catalytic converters, heat shields or other parts of the ve-
hicle which reach high temperatures.

Cleaning the engine compartment
The engine compartment of any motor vehicle is a potentially hazardous
area ⇒ page 180. The engine compartment should only be cleaned by qualified personnel. If
it is not correctly cleaned, the anti-corrosion coating and consequently elec-
trical components may be damaged. Moreover, water may filter directly into
the vehicle interior through the water chamber ⇒ 
.
If the engine compartment is very dirty, always take the vehicle to a special-
ised workshop for professional cleaning. SEAT recommends visiting a Tech-
nical Service.
Water box
The water box is in the engine compartment, between the windscreen and
the engine, and beneath a perforated cover. Air is taken in through the wa-
ter box from outside to the vehicle interior via the heating and air condition-
er.
Leaves and other loose objects should be regularly cleaned away from the
water box either by hand or with a vacuum.
WARNING
When working on the engine or in the engine compartment, there is a
risk of injury, burns, accident or fire.
● Before starting work, please ensure you are familiar with the required
procedure and the safety precautions ⇒ page 180.
● SEAT recommends you have this work performed by a specialised
workshop.
CAUTION
If water is manually poured into the water box (for example, using a high
pressure cleaning appliance), this could cause significant damage to the ve-
hicle.
For the sake of the environment
Only wash the engine compartment in areas allocated for this purpose, to
prevent dirty water which may be contaminated by oil, grease or fuel, from
entering the drains. In some districts, the engine compartment may not be
washed outside the wash bays provided for this purpose. 

208Vehicle care and maintenance
Cleaning storage compartments and drinks holders
● Use a clean, damp, lint-free cloth to clean parts.
● If this does not provide satisfactory results, we recommend using a spe-
cial solvent-free plastic cleaning product.
Cleaning the ashtray
● Extract the ashtray and empty it.
● Clean the ashtray with a dishcloth.
Use a toothpick or similar to remove ash from the area where cigarettes are
stubbed out ⇒ Fig. 122. 
Care and cleaning of plastic parts, wooden trim and the
instrument panel
● Use a clean, damp, lint-free cloth to clean parts.
● Clean plastic parts (inside and outside the vehicle) and the dash panel
with a special solvent-free product for the care and cleaning of plastic, ap-
proved by SEAT ⇒ 
.
● Wash wooden trims with a mild soap and water solution.
● Clean the Portable Navigation System housing (Supplied by SEAT) with a
dry cloth only.
WARNING
Solvents cause the surfaces of the airbag modules to become porous. If
an airbag is accidentally triggered, the detachment of plastic parts could
cause serious injury.
● Never clean the dash panel and the surfaces of the airbag modules
with cleaners containing solvents.
CAUTION
When cleaning the instrument panel, be careful not to dampen the Portable
Navigation System connections as this can damage the electrical installa-
tion. 
Cleaning seat belts
If the seat belt is very dirty, the belt retractor may not work correctly thus
preventing the seat belt from operating correctly.
The seat belts should never be removed from the vehicle for cleaning.
● Use a soft brush to remove the worst dirt ⇒ 
.
● Pull the seat belt right out and leave it out.
● Clean dirty seat belts with a gentle soap and water solution.
● Wait until they are completely dry.
● Only allow the seat belt to retract when it is completely dry.
WARNING
Check the condition of all the seat belts at regular intervals. If the web-
bing or other parts of the seat belt are damaged, the vehicle should be
taken to a Specialised workshop immediately and the belts should be re-
placed. It is extremely dangerous to drive using damaged seat belts and
could result in serious injury or loss of life.
● Seat belts and their components must never be cleaned with chemi-
cal products, nor should they be allowed to come into contact with corro-
sive liquids, solvents or sharp objects. This could affect the strength of
the seat belt webbing. 

212Vehicle care and maintenance
perfect condition on the outside and which have a tread depth within the
values stipulated by the Law ⇒ 
.
The date of manufacture, part of the tyre identification number (TIN), indi-
cates the age of the tyre ( ) ⇒ page 218.
Storing tyres
Mark tyres when you remove them to indicate the direction of rotation (left,
right, forwards, backwards). This ensures you will be able to mount them
correctly when you replace them. When removed, the wheels and/or tyres
should be stored in a cool, dry and preferably dark location. Do not place
tyres mounted on the wheel in a vertical position.
Protect tyres not mounted on wheels from dirt by storing them in suitable
bags and standing them on the ground on their tread.
WARNING
Aggressive fluids or substances could result in visible or invisible dam-
age with the consequent risks.
● Always ensure that tyres do not come into contact with chemical
products, oil, grease, fuel, brake fluid or other aggressive substances.
WARNING
Old tyres, even if they have never been used, may lose air or burst unex-
pectedly while driving, resulting in serious accident or damage.
● If tyres are over six years old, they should only be used in an emer-
gency and with extreme caution.
For the sake of the environment
Old tyres must be disposed of by qualified personnel according to the laws
in the country concerned. Wheel rims
The design of wheel bolts is matched to the rims. If different rims are fitted,
the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that
the brake system functions correctly
⇒ page 252.
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel.
The tyres and rims approved by SEAT are specially matched to the character-
istics of the vehicle and are critical to good road holding and safe handling.
Wheel bolts
Wheel bolts must be tightened to the correct torque ⇒ page 252.
Beadlock wheel rims
Beadlock wheel rims have various components. These are joined together
by special bolts using a special procedure. This ensures good performance,
a better seal, improved safety and wheel run out. Therefore, worn rims
should always be replaced and must only be repaired in a specialised work-
shop. SEAT recommends visiting a Technical Service ⇒ 
.
Wheel rims with bolted trims
Wheel rims may be fitted with interchangeable trim parts which are attach-
ed to the rim using self-locking bolts. Worn trims should only be replaced at
a specialised workshop. SEAT recommends visiting a Technical Service
⇒
