Oil level in area
–Oil must be topped up. The indicated oil level should be after in zone
Depending on how you drive and the conditions in which the vehicle is used,
oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely to be
higher for the first 5000 km. For this reason the engine oil level must be
checked at regular intervals, preferably when filling the tank and before a
journey.
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 221.
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

Engine oil specification ⇒page 224.
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 specialised 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!•Before opening the bonnet, read and observe the warnings
⇒ page 221, “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 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.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.

Checking and refilling levels
228•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.CoolantCoolant 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 G 12+ additive or an additive with the TT-VW 774 F specification (it has a
purple colour). This mixture provides the necessary freeze protection 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 G 12+ additive can be increased. However, the percentage of coolant
add it iv es s ho uld n ot e xcee d 6 0% , as this wo u ld re d uce t he fr ee ze pro tec ti on.
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 G 12+ additive 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,
causing serious damage to the engine.•The G 12+ additive (purple) can be mixed with the G 12 (red) or G 11 addi-
tive. Never mix G12 (red) with G 11.WARNING (continued)

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 221.
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 below the “MIN” mark, top up with coolant.
To p p i n g u p c o o l a n t
–Only use
new coolant liquid.
– 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 illustration ⇒page 277.
Make sure that the coolant meets the required specifications ⇒ page 228.
D o not use a d if fe re nt ty pe of add it ive if G 1 2+ add iti ve is n ot a vaila ble . In th is
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 228.
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.
The G 12+ additive (purple) may be mixed with G 12 (red) and also with G 11.
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 221.•When the engine is warm or hot, the cooling system is pressurised! Do
not unscrew the cap on the expansion tank when the engine is hot. This is
a burn injury risk.

Caution•When mixed with other additives the colour of G 12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to do
so will result in engine damage!•If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large
coolant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage.Washer fluid and windscreen wiper bladesTopping up washer fluid
Y
The water for cleaning the windscreen should always be
mixed with washer fluid.
The windscreen washer and the headlight washers are supplied with fluid
from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean th e windscreen and headlights. We recom-
mend that you always add a product to the windscreen washer fluid.
Approved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
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 221.Caution
•Never put radiator anti-freeze or other additives into the windscreen
washer fluid.•Always use approved windscreen cleansing products diluted as per
instructions. If you use other washer fluids or soap solutions, the tiny holes
in the fan-shaped nozzles could become blocked.

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 illustration ⇒page 277. 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 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 221.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 221 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.
