Checking and refilling levels
Engine oil specification ⇒ page 220.
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 A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a specialised work-
shop.
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust 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 re-
quired!
● Before opening the bonnet, read and observe the warnings
⇒ page 217, Safety instructions on working 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
horizontal 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.
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 spe-
cialist 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 must be large
enough to hold all the engine oil. 

Coolant
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G 12+ or an additive with the specification TT-VW
774 F (it is dyed purple). This mixture provides the necessary freeze protec-
tion down to -25°C and protects the alloy parts of the cooling system
against corrosion. It also prevents scaling and raises the boiling point of the
coolant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G 12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40°C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G 12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death.
CAUTION
● Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant, caus-
ing serious damage to the engine.
● The coolant additive G 12+ (purple) can be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11. 
Checking the coolant level and topping up 
The correct coolant level is important for fault-free function-
ing of the engine cooling system.

Changing the front windscreen wiper blades
If the windscreen wiper blades are in perfect condition, you
will benefit from an improved visibility. Damaged wiper
blades should be replaced immediately.
Fig. 148 Changing the
front wiper blades
Changing wiper blades can be done in both the rest and horizontal
positions. Ensure that the wiper blades are not frozen.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Press on the side tabs A
and release the blade moving it in the
direction of the arrow 1 ⇒ fig. 148.
Fitting the wiper blade
– Insert the tab 2
into the slot 3 of the blade
⇒ fig. 148. –
Move the blade towards the arm in the opposite direction of the
arrow 1
,until it clicks into position
⇒ fig. 148.
– Push the wiper arms back against the windscreen.
If the windscreen wipers smear , they should be replaced if they are dam-
aged, or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a special-
ised workshop and corrected if necessary.
WARNING
Do not drive unless you have good visibility through all windows!
● Clean the windscreen wiper blades and all windows regularly.
● The wiper blades should be changed once or twice a year.
CAUTION
● Damaged or dirty windscreen wipers could scratch the windscreen.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
● Never move the windscreen wiper or windscreen wiper arm manually.
This could cause damage.
● Do not pull the windscreen wipers forward unless they are in the service
position. Otherwise the bonnet could be damaged.
Note
● The wiper arms can be moved to the service position only when the bon-
net is properly closed. 

Checking and refilling levels
Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 151 In the engine
compartment: Brake fluid
reservoir cover
– 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 en-
gine compartment illustration ⇒ page 273. 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
instrument panel will warn you if the brake fluid level is too low ⇒ page 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217.

Changing the brake fluid
The Maintenance Programme 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 217 in
section “Safety notes for 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 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 ob-
serve the warnings ⇒ page 217. 

General notes
Avoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– 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
– When you remove the tyres, mark them in order to maintain the
same direction of rotation when they are installed again.
– 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 must be run in ⇒ page 189.
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 readily visible. If you notice unusual
vibrations or the vehicle pulling to one side, this may indicate that one of
the tyres is damaged. The tyres should be checked immediately by an Au-
thorised 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 direction 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 during the first 500 km. Drive
particularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may cause an accident.
● If you notice unusual vibrations or if the vehicle pulls to one side
when driving, stop the vehicle immediately and check the tyres for dam-
age.

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. 
