~ Add coolant mixed in the correct ratio
¢ page 166 up to the upper marking.
~ Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak. Im­
mediately drive your vehicle to an authorized
Audi dealer or authori zed Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cooling system.
.&, WARNING
The cool ing system is pressu rized and can be­
come very hot. To reduce the r is k of burns
from hot coolant :
- Do not open the coo lant expansion tank cap
when the engine is hot. This increases the 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 .
- T urn the coo lant tank cap co unterclo ckwise
slowly and keep light pressu re on the cap .
- T o reduce the risk of burns , do not allow any
antifreeze o r coolant to drip onto the ex­
haust system or hot engine components.
T he ethylene glycol in engine coolant can
catch fire under certain circumstances .
- T he coo lant add itive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- 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 .
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driv ing . See an authorized Audi deal -
Check ing and Filling
er or authorized Aud i Service Facility for assis ­
tance .
- Before the start of winter, have your author­
ized Aud i dea ler or a uthorized Audi Serv ice
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropr iate coo lant add itive is not
availab le in an emergency, do not add any
other additive . You could damage the en­
gine. If this happens, only use water and re­
store the correct m ixtu re ratio with the
specified coolant add it ive as soo n as poss i­
ble .
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .
Radiator fan
T he radiator fan switches on automatically by it ­
self.
An auxiliary e lectr ic radiator fan switches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan c a n continue running for up to 10 m inutes - even
with the ignition off . It can even switch on aga in
later by itself ¢.& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up bec ause the
veh icle is parked in in tense sunlight.
.&, WARNING
--
- To reduce the r isk of personal injury never
touch the radiator fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not runn ing .
- The auxiliary radiator fan sw itches on auto ­
mat ica lly when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature d rops .
