Engine oil pressure malfunction
~
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 .

pressure is too low. An additional driver message can also be
displayed by pressing the
[CHECK] button :
Switch off engine ! Oil pressure too low
Immediate actions

Dipstick readings checks too low
- Top off oil to the proper level=> page 282 .
Make sure that the oil pressure warning symbol "t=:;r:
appears no longer in the display before you start driving
again.
Dipstick reading checks OK

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.
W Tips
• The engine oil pressure symbol 't=1: 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
't=1: starts to flash before you respond to the low oil
level warning -. By then, your engine may already have suffered
serious damage. •

same time, a warning symbol appears in the display.

two warning thresholds that function
independently of each other and that have somewhat different
purposes :
Speed warning 1
You can use speed warning 1 to set the maximum speed while you are
driving. This setting w ill remain in effect until you turn off the igni­
tion, assum ing that you have not changed or reset the setting .
Th e speed warning symbo l
'8 (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed.
It goes out when the speed falls be low the stored maximum speed.
Th e speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted.
