– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.

Air recirculation mode
⇒page 146, fig. 110 prevents strong odours in
the outside air from entering the vehicle interior, for example when passing
through a tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the cold air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the ambient air. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting .
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.

– Press the temperature selectors to set the desired temperatures
for the left and right sides of the interior. We recommend 22°C
(72°F).A comfortable interior climate is quickly reached when a temperature of
+22°C (72°F) is set in automatic mode. It can be changed as necessary to suit
individual preferences or particular cir cumstances. It is possible to select
interior temperatures from +16°C (61°F) to +29.5°C (86°F). These are approx-
imate temperatures and the actual temp erature may be slightly higher or
lower depending on the ambient conditions. Climatronic maintains a constant temperature level fully automatically. The
temperature of the air supplied to the interior, the blower speed and the air
distribution are regulated automatically. The system also allows for the effect
of strong sunlight, so there is no n
eed for manual adjustment. Therefore,
automatic mode provides the best comfort for the vehicle occupants in virtu-
ally all conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, air flow or . The temperature will
continue to be regulated within the parameters manually selected by the

General notesThe pollen filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the ambient air, including dust and
pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Caution
•
If you suspect that the air conditioning is damaged, switch off the air
conditioning with button to prevent further damage and have it
checked by a qualified workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
It is advisable to connect the air conditioning at least once a month, to
lubricate the system gasket s and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

Intelligent technology
174Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 172.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒page 78.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.
•
Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehi cle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL ⇒page 199.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating ⇒page 172.Brakes
What factors can have a negative effect on the brakes?New brake pads
New brake pads do not provide optimal performance during the first 400 km,
they must be “run in”. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. Avoid over-
loading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive and
the conditions in which the vehicle is operated. Negative factors are, for

176•
If you wish to equip the car with accessories such as a front spoiler or
wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town, drive short distances or have a sporty driving style, we recom-
mend that you have the thickness of your brake pads checked by an Approved
Service Centre more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be dried by pressing the pedal to restore full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
On steep descents if the brakes are excessively used they will over
heat. Before driving down a long steep gradient, it is advisable to reduce
speed and change to a lower gear (or move the selector lever to a lower gear
if your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.
•
Never let the brakes “rub” by applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not function.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long . This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒page 199, “Modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Power steering (servotronic*)
The power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed to turn the
steering wheel. In cars equipped with servotronic* power steering the degree
of power assistance is regulated electronically according to road speed.
If a fault should occur in the servotronic system the power steering* will still
operate. The degree of power assistance will, however, no longer adapt to

Driving and the environment
184With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumptio n does not regularise until having
driven some four kilometres. This is the reas on why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by
as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
Save electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.
Logbook
A good way of keeping a check on fuel consumption is to take regular notes.
You will be able to note the variations (both positive and negative) and react
accordingly.

Cleaning and caring for your vehicle
198SEAT does everything possible to preserve the special qualities of leather, as
a natural product. Because of the natural properties of the specially selected
hides employed, the finished leather has a certain sensitivity to grease and
dirt, etc. so a degree of care is required in everyday use and when looking
after the leather.
Dust and grit in the pores and seams can scratch and damage the surface. If
the vehicle is left standing in the sun for long periods, the leather should be
protected against direct sunlight to pr event it from fading. However, slight
colour variations in high-quality natural leather are normal.
Caution
•
Do not use solvents, wax polish, shoe cream, spot removers or similar
products on leather.
•
To avoid damage, stubborn stains should be removed by a qualified
workshop.
Cleaning seat belts
A dirty belt may stop the seat belt working properly.Keep the seat belts clean and check all seat belts regularly.
Cleaning seat belts
– Carefully pull the dirty seat belt right out and leave it out.
– Clean the dirty seat belts with a gentle soap solution.
– Allow the seat belt fabric to dry.
– Do not roll up the seat belt until it is dry.
If large stains form on the belts the belt will not retract correctly into the auto-
matic belt retractor.
WARNING
•
Do not use chemical cleaning agents on the seat belts, as this can
impair the strength of the webbing. Ensure that the belts do not come into
contact with corrosive fluids.
•
Check the condition of all seat belts at regular intervals. If you notice
that the belt webbing, fittings, retrac tor mechanism or buckle of any of the
belts is damaged, the belt must be replaced by a specialist workshop.
•
Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.Caution
After cleaning, allow seat belts to dr y completely before rolling them up.
Otherwise the belt retractors could become damaged.
