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.

Engine oil specification
⇒page 207.
WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
Caution
If the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a qualified work-
shop.
For the sake of the environment
The oil level must never be above ar ea . Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the
exhaust system.Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule.We recommend that you have the engine oil changed by an Authorised
Service Centre.
The oil change intervals are shown in the Maintenance Programme.
WARNING
Only change the oil yourself if you have the specialist knowledge required!
•
Before opening the bonnet, read and observe the warnings
⇒ page 204, “Safety instructions on wo rking in the engine compartment”.
•
Wait for the engine to cool down. Hot oil may cause burn injuries.
•
Wear eye protection to avoid injuries caused by splashes of oil.
•
When removing the oil drain plug with your fingers, keep your arm hori-
zontal to help prevent oil from running down your arm.
•
Wash your skin thoroughly if it comes into contact with engine oil.
•
Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children until it is disposed of.Caution
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
•
Because of the disposal problems, the necessary special tools and
specialist knowledge required, we recommend that you have the engine oil
and filter changed by an Authorised Service Centre.
•
Never pour oil down drains or into the ground.
•
Use a suitable container when draining the used oil. It has to be large
enough to hold all the engine oil.

Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.The position of the brake fluid reservoir is shown in the corresponding engine
compartment diagram ⇒page 266. The brake fluid reservoir has a black and
yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear. However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low
⇒page 72.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒ page 204.Changing the brake fluid
The Maintenance Program indicates the brake fluid change
intervals.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 204 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
It is important that you use only brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is toxic. Old brake fluid impairs the braking effect.

220Charging and changing the vehicle battery
The battery is maintenance-free and is checked during the
inspection service. All work on the vehicle battery requires
specialist knowledge.If you often drive short distances or if the vehicle is not driven for long
periods, the battery should be checked by a qualified workshop between the
scheduled services.
If the battery has discharged and you have problems starting the vehicle, the
battery might be damaged. If this happens, we recommend you have the
vehicle battery checked by an Authorised Service Centre where it will be re-
charged or replaced.
Charging the battery
The vehicle battery should be charged by a qualified workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and has
special safety features.
Genuine SEAT batteries fulfil the maintenance, performance and safety spec-
ifications of your vehicle.
WARNING
•
We recommend you use only maintenance-free or cycle free leak-proof
batteries which comply with the st andards T 825 06 and VW 7 50 73. This
standard applies as of 2001.
•
Before starting any work on the batteries, you must read and observe
the warnings ⇒ in “Warnings on handling the battery” on page 218.
For the sake of the environment
Batteries contain toxic substances such as sulphuric acid and lead. They
must be disposed of appropriately and must not be disposed of with ordinary
household waste.
