temperature is too h igh or
the eng ine coolant
level is too low . A dr iver
message appears as well to explain the mal­
function in more detail. The d rive r warning
goes out afte r about 5 seconds, but it ca n be

• Add coolant if ne cessa ry ¢ page 241 .
• Co ntin ue d riving only after the eng ine cool­
ant warn ing/ indicato r light goes o ut.
• Contact your a uthorized Audi dea ler for as-

"l:::r. Engine oil pressure malfunction
T he red engine oil pressure warning symbol
requires immediate service or repair. Driving with a low
oil pressure indication is likely to
cause severe engine damage .
If the . symbo l on the disp lay flashes, the
engine oil pressure is too low. A driver mes­
sage appears as we ll to exp la in the malfunc ­
t io n in more detail. The dr iver warning goes
o ut afte r abo ut 5 seconds , but it can be
brought up at any t ime by p ressing the
~ 1s =ET= I
button ag ain.
Turn off engin e! O il pressure too low
• Stop the vehicle.
• Turn the engine off.
• Chec k the engine o il level ¢
page 238 .
• Contact yo ur au thorized Aud i deale r for as-
sistance if necessa ry.
Eng ine oil level too low
If the engine oil level is too low, add engine
o il
¢page 238.
Engine oil leve l correct
If the symbol . flashes even tho ugh the en­
gine oil leve l is correct, please contact your
nearest authori zed Aud i Dea ler for assistance.
Do not continue dr iving . Do not leave the en­
gine running
idle, either .
(D Tips
- The engine oil pressure symbol. is
not an indicator for a low eng ine oil lev­
e l. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel, and always before going on a long trip .

engine is warm, the level may be slightly
above the "MAX" marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 235.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 30 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the 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.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 233.
... Turn off the engine .
... Let the engine cool down.
Checking and filling 241
... Place a thick rag over the coolant expansion
tank ¢
page 240, fig. 199 and carefully turn
the cap counter-clockwise ¢
A.
... Add coolant.
... Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive
Gl2+
+, Gl3
or in an emergency Gl2 +. Do not use a
different additive . In an emergency use plain
water until you can get the correct additive and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out 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 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 while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
-Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
