Engine oilEngine oil specifications
The engine used must conform to exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of good quality oil is nec essary for the correct operation and long
service life of the engine, when it becomes necessary to replenish or change
the oil, always use an oil that complies to the VW standards.
If it is not possible to find oil conforming to the VW standards then oil
conforming to the ACEA or API standards with an appropriate viscosity at
atmospheric temperature should be used in stead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

– Pull the dipstick out again and check the oil level ⇒ page 208,
fig. 154.
– Replace the dipstick, pushing it in as far as it will go.The position of the dipstick is shown in the corresponding engine compart-
ment diagram ⇒page 262.
If the oil level is in area ⇒page 208, fig. 154 , do not top up with oil.
If the oil level is in area , you may top up with oil (approx. 0,5 l).
If the oil level is in area , you must top up with oil (approx. 1,0 l).
It is normal for the engine to consume a certain amount of oil. Consumption
can be up to 1.0 litres per 1,000 km. For this reason the engine oil level must
be checked at regular intervals, prefer ably when filling the tank and before a
journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, when towi ng a trailer or climbing on mountain
passes, the oil level should preferably be kept within area and not above
this.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartment, always observe the safety
warnings ⇒ page 203.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 an Authorised
Service Centre.
Topping up engine oil

Top up gradually with small quantities of oil.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 203.
– Un screw cap from oil filler
opening ⇒ fig. 155.
– Top-up oi

l in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using small quantities, wait a while and check the oil level before
adding any more oil.

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 71.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 203.Changing the brake fluid
The brake fluid must be renewed every two years.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 203 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the cour se 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.
For this reason the brake fluid must be renewed every two years.
It important that you use only use brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
•
Before opening the bonnet to check the brake fluid level, read and
observe the warnings ⇒page 203.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. This represents a toxic danger.
•
Have the brake fluid changed every two years at the latest. Heavy use
of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. This would seriously affect the efficiency of the brakes and the
safety of the vehicle. This may be an accident risk.Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.

If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 203 ⇒ in “Warnings on handling the battery” on
page 218.
– Check the colour display in the magic eye on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒page 262.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.
Charging 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 their 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 standards 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 environmentBatteries 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.WheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very slowly and as near as possible at a right angle to the kerb.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– Mark tyres when you remove them to indicate the direction of
rotation. This ensures you will be able to install them correctly
when you replace them.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel rims.
New tyres
New tyres have to be run in ⇒page 179.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Concealed damage
Damage to tyres and rims is often not re adily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the di rection of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•
New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may be an accident risk.
•
If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.

Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflation pressure from the sticker. The
values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!•
At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
•
If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre service life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.
