264 Check ing and filling
Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system
or hot eng ine parts. Under certain condi­
t io ns, the ethy lene g lycol in engine cool­
an t ca n ca tch f ire.
0 Note
Do not add any type of radiator leak seal­
ant to your vehicle's eng ine coolant. Add­
ing radiato r repair fluid may adve rsely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything i n the engine com­
pa rtmen t,

We recommend using only coo lant add it ive
G12 ++, G13 or in an emergency G12 +. Do
not
use a different add itive. In an emergency use
plain water until you can get the correct addi­
t ive and can restore the correct ratio . This
shou ld be done as soon as poss ib le.
If you have lost a considerab le amount of
coolant, the n you should add cold ant ifreeze
and co ld water on ly when the eng ine is cold .
Always use
new engine coolant when refilling.
Do not fi ll coo lant above the "MAX" mark. Ex­
cess coolant will be forced o ut through the
pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn off the engine and allow it to coo l
down.

cond it ions, the ethylene g lycol in e n­
gine coolant can catch fire .
