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 coolant additive G 12+ or an additive with the specification TT-VW 774 F
(it is dyed purple). This mixture gives the necessary frost protection down to
-25°C and protects the alloy parts of th e 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 frost
protection is not required.
If greater frost 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 frost
protection. It would also reduce the cooling effect. A mixture with 60%
coolant additive will give frost 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 ambient temperatures, the coolant
could freeze, causing the vehicle to br eakdown. As the heater would also
not work in this situation, there is a risk of suffering exposure!
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 215.

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 ex pansion 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 279.
Make sure that the coolant meets the required specifications ⇒page 223.
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 223.
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 coolant additive G 12+ (dyed purple
) may be mixed with G 12 (dyed 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 215.
•
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 has been lost, wait for the engine to cool down before
putting in cold coolant. This avoi ds damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.

Washer fluid and windscreen wiper bladesTopping up washer fluid
The water for cleaning the windscreen should always be
mixed with washer fluid.The windscreen washer and the headlight washing system are supplied with
fluid from the windscreen washer flui d 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 the 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 compartm ent, always observe the safety
warnings ⇒page 215Caution
•
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 fl uids or soap solutions, the tiny holes
in the fan-shaped nozzles could become blocked.

226Changing windscreen wiper blades
If the windscreen wiper blades are in perfect condition, you
will benefit from an improv ed visibility. Damaged wiper
blades should be replaced immediately.
To change the blades it is necessary to change the rest position of
the wipers to the service position.
Service position (for changing wiper blades)
– Ensure that the wiper blades are not frozen.
– Turn ignition on and off and then (before approx. 8 seconds have
elapsed), move the windscreen wi per lever to the intermittent
wipe position. The windscreen wipers will move to the service
position.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Push the side buttons, free the blade and pull in the direction of the arrow ⇒page 226, fig. 170 .
Fitting the wiper blade
– Insert a blade of identical length and design into the wiper arm.
– Slide the blade until it clicks into position.
– Push the wiper arms back against the windscreen.The windscreen wiper arms return to their original position when the ignition
is turned on and the windscreen wiper lever is operated, or when driving
faster than 6 km/h.
If the windscreen wipers smear , they should be replaced if they are damaged,
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 qualified
workshop and corrected if necessary.

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 215.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 215 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.
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.
•
Before opening the bonnet to check the brake fluid level, read and
observe the warnings ⇒page 215.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
•
Complete the brake fluid change according to the Maintenance
Program. 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 cause an accident.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.

particles containing lead.
•
Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralize any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
•
Fires, sparks, naked lights and smoki ng are prohibited. When handling
cables and electrical equipment, avoid causing sparks and electrostatic charge. 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 bu lb is changed, you need only switch
off the light.
