Coolant loss
Coolant loss may indicate a leak in the cool ing
system . In the event of coolant loss, the cool
ing system should be inspected immediately
by your authorized Audi d ealer. It is not
enough merely to add coolant.
I n a
sea led 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 coo l
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 be ing burned, do not spill ant i
freeze or coolant on the exhaust system
o r hot eng ine parts. Under certai n condi
t ions, the ethy lene g lycol i n engine cool
an t ca n ca tch fire.
(D Note
Do not add any type of rad iator leak seal
ant to you r vehicle's eng ine coolant. Add
ing radiator repair f luid may adversely af
fec t the function and pe rformance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
