@ Tips
The instrument illumination (for dials and
needles) turns on when the ignition is on
and the vehicle lights are turned off . As
the daylight fades, the illumination of the
dia ls likewise dims automatically and will
go out completely when the outside light
is very low. This feature is meant to rem ind
you to switch on the headlights when out­
side light conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge CD c:> page 10, fig. 3
only works when the ignition is on . To prevent
damage to your engine, please note the fol­
l owing important points:
Engine cold
,.._ N

" a,
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operating
temperature yet. Avoid high engine speeds, heavy engine loads and heavy th rottle applica­
t ions.
Normal temperature
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on unde r normal driv ing cond i­
t ions . Th e LEDs higher up may turn on when
the engine is under heavy load or the exterior
temperature is high. This is no need to worry
as long as the . warning light in the instru­
ment cluster does not illum inate . If the LEDs
in the upper area of the disp lay and the indica­
tor light . in the instrument cluster display
turn on, the coolant temperature is too high

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

20 Instruments and warning/indicator lights
If this warning/indicator light illuminates
while you are driving, then there is a mal­
function in the engine electronics. Have the malfunction corrected as soon as pos­
sible by your authorized Audi dealer or
qualified repair facility .
o Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) is part
of the On-Board Diagnostic (OBD II) system.
The symbol
¢..j lights up when the ignition is
switched on and will turn off after the engine
has started and has settled at a constant idle
speed. This indicates that the MIL is working
properly.
The warning light illuminates when there is a
malfunction in the engine electronic system.
Contact your authorized Audi dealer and have
the malfunction corrected .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢ page 208.
For more information ¢ page 29.
!?) Engine speed limitation
II! Engine speed maximum XXXX RPM
The engine speed is automatically limited to
the speed displayed in the driver information
system. This protects the engine from over­
heating.
The engine speed limitation deactivates once
the engine is no longer in the critical tempera­
ture range and you have released the accelera­
tor pedal once.
If the engine speed limitation was activated
by an engine control malfunction, the indica­
tor light
Ga also turns on. Make sure that the
speed does not go above the speed displayed .
Drive to your authorized Audi dealer immedi­
ately to have the malfunction corrected.
'
(!) Tips
The engine speed is limited when the en­
gine is cold -the full engine output is not
available. When the engine is at operating
temperature, the red area in the tachome­
ter moves to a higher RPM range .
~~, Engine oil sensor
• Oil level! Sensor defective
If the symbol illuminates, contact your au­
thorized Audi dealer and have the oil sensor inspected . Until you have this done, check the
oil level each time you refuel just to be on the
safe side
¢ page 215.
? Request to warm engine by driving
0 Please warm up engine
Fuel has entered the engine oil because of low
outside temperatures or frequent short
drives . Drive until the engine is warm so that
the fuel in the engine oil will vaporize. Avoid
high engine speeds, full acceleration and
heavy engine load when doing this.
Bu Fuel level indicator
D Please refuel
If the indicator light turns on for the first
time and the message appears, there are
about 2.6 gallons (10 liters) of fuel left in the
tank. Time to refuel
¢ page 207.
D Tank system malfunction! Contact dealer
If the indicator light turns on and this mes­
sage appears, there is a malfunction in the
tank system.
Drive to your authorized Audi dealer immedi ­
ately to have the malfunction corrected.
