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 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 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. This represents a toxic danger. 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 201 .

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 tank is shown in the corresponding 
engine compartment diagram  ⇒page 260.
Make sure that the coolant meets the required specifications  ⇒page 209. 
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 209.
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 201
•
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.

Checking and refilling levels
214If this is not sufficient, refer to a qualified workshop.
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
•
A damaged or dirty window wiper could scratch the rear window.
•
Never use fuel, nail varnish remover, paint thinner or similar products to 
clean the window.
•
Never move the windscreen wiper by hand. This could cause damage.
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 coolant expansion tank is shown in the corresponding 
engine compartment diagram  ⇒page 260. 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.
