(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev ­
el. 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.
- The yellow oil level warning indication

Malfunction Indicator Lamp (MIL)
The Malfunction Ind icator Lamp (MIL) ¢'4 i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after the engine starts and the id
le has stabilized.
This indicates that the MIL is working proper­
ly .
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may ex ist in the engine sys­
tem.
If the light illuminates, the catalytic con­
verter could be damaged .
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your authori zed Audi dealer.
If the light illuminates, the electronic speed
limiter may also be malfunctioning . For more
