before check-
ing anything in the engine compartment
Q page236.
Checking the engine coolant level
"" Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q
page 238, fig. 184. The coolant level
must be between the markings when the en-
gine in cold. When the engine is warm it can be
slightly above the upper marking.
Adding coolant
Requ irement: there must be a residual amount of
coolant in the expansion tank
c:? (i).
""Let the engine cool down.
.. Place a cloth over the coolant expa nsion tank
cap and unscrew the cap counterclockwise
c:? ,8..
"" Add coolant mixed in the correct ratio
i:? page 242 up to the upper marking.
"" Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely.
A coolant loss suggests a leak. Immediately drive
your vehicle to an authorized Audi dealer or au-
thorized Audi Service Facility and have the cool-
ing system inspected. If the cooling system is not
leaking, a loss can come from the coolant boiling
through overheating and being pushed out of the
cooling system.

WARNING
-
The cooling system is pressurized and can be-
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
with the engine hot. There is a risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto t he ex-
Checking and Filling
haust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
away from children. There is a risk of poi-
soning.
- 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 personal injury.

Note
Do not add coolant if the expansion tank is
empty. Air cou ld enter the cooli ng system and
damage the eng ine. If this is the case, do not
continue driving. See an authorized Audi dea l-
er or authorized Audi Service Facility for assis-
tance.
Radiator fan
The radiator fan switches on automatically by it-
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes - even
with the ignition off. It can even switch on aga in
later by itself
c:?
& .
if
- the temperature of the eng ine coolant rises due
to the heat build-up from the engine in the en-
gine compartment, or
- the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&.
WARNING
- To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
