- Turn off the engine.
- Check coolant level~
page 317.
-Add coolant if necessary ~ page 318.
-Continue dr iving only after the eng ine coolant
warning/ indicator light goes out .
- Contact your authorized Audi dealer for assistance if
necessary .
If the engine coolant le ve l is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
~ page 18, then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
~ page 73, "Emer­
gency flasher
A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
~ page 301, "Engine compartment".
0 Note
Do not continue driving if the -~- symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction "t=:?:
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low -oil -pres ­
sure indication is likely to inflict severe damage to the
engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the
I CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road.
- Stop the vehicle.
- Turn off the eng ine.
- Check the engine oil level
with the dipstick~ page 313.
Dipstick readings checks too low
- Top off oil to the proper level~ page 314.
-Make sure that the oil pressure warning symbol~
appears no longer in the display before you start driving
again. .,,,

Dipstick reading checks OK
-If the oil pressure warning symbol "t=:7: starts flashing
again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[ i] Tips
• The engine oil pressure symbol ~ is not an indicator for a low
engine oil level. Do not rely on it . Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip .
• The yellow oil level warning indication .: requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning
~ starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •

& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine

force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries .
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immediately after hard or extended driving.
Keep the engine running for approximately two minutes to prevent
excessive heat build-up.•
