Oil properties
Viscosity
The viscosity class of the oil is selected according to the diagram.
When the ambient temperature falls outside the limits of the scale for a short
period, an oil change is not required.
Mono-grade oil
Single grade oils are generally not suitable for all year round use, due to
ranges of viscosity
21). These oils are only useful in a climate that is constantly very cold or very
warm.
Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.

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 211.
– Unscrew cap from oil filler opening ⇒fig. 167.
– Top-up oil 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.
– As soon as the oil level is in area , carefully close the cap.The position of the oil filler opening is shown in the corresponding engine
compartment diagram ⇒page 275. Engine oil specification
⇒page 214.
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 area . 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!

Caution
•
Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant,
causing 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 func-
tioning of the engine cooling system.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 211. Opening the coolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒.
Checking coolant level
– Look into the open coolant expansion tank and read off the coolant level.
– If the level is underneath the “MIN” mark, top up with coolant.
Topping up coolant
–Only use new coolant.
– Do not fill above the “MAX” mark.
Closing the coolant expansion tank
–Screw the cap on again tightly.
The position of the coolant expansion reservoir is shown in the corresponding
engine compartment diagram ⇒page 275.
Make sure that the coolant meets the required specifications ⇒ page 218.
Do not use a different type of additive if coolant additive G 12+, is not avail-
able. In this case use only water and bring the coolant concentration back up
to the correct level as soon as possible by putting in the specified additive
⇒ page 218.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise the excess coolant will be forced
out of the cooling system when the engine is hot.

224Brake 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 275. 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 noticeab
ly 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 211.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 211 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 consider ably 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 poisonous. Old brake fluid impairs the braking effect.

226charge. Never short the battery terminals. High-energy sparks can cause
injury.•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
•
Keep children away from acid and batteries.
•
Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.
•
Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
•
Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.
•
Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.
•
Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•
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 211 ⇒ in “Warnings on handling the battery” on
page 225.
– 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 show n in the corresponding engine compart-
ment diagram ⇒page 275.
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.
