Checking and Filling

— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
— You can continue driving if the permitted
G12evo coolant additive was not added.
However, go to an authorized Audi dealer or
authorized Audi Service Facility immediately
to have the coolant replaced to reduce the
risk of engine damage.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide
you with important information about
the recommended coolant additive.

>» Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 202.
> Check the coolant level in the coolant expan-
sion tank > page 203, fig. 168 using the outer
markings @) > fig. 177. The coolant level must
be between the markings 2) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.

208
If you must add coolant, use a mixture of water
and coolant additive. Audi recommends mixing
the coolant additive with distilled water.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Remove the cover (1) > fig. 777 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 207 up to the upper marking @)
> fig. 177.
» Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

Z\ WARNING
— The motor compartment in any vehicle is a
potentially dangerous area. Stop the engine
and allow it to cool before working in the
engine compartment. Always follow the in-
formation found in > page 200, General in-
formation.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
