Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions¢ &.
Messages may appear with some indicator lights .
A warning signal will sound at the same time.
The messages disappear again after a short time.
To display a message again, press the
I SE TI but­
ton ¢
page 11. If several malfunctions occur,
each of the indicator/warning lamps will be dis­

8_ WARNING
- Failure to heed warning lights and other im­
portant vehicle information may resu lt in
serious personal injury or vehicle damage.
- Whenever sta lled or stopped for repa ir,
move the vehicle a safe distance off the
road, stop the engine, and turn on the emer­
gency flasher ¢
page 46.
-The engine compartment of any motor vehi­
cle is a potentially hazardous area. Before
you check anything in the engine compart­
ment, stop the engine and let it cool down.
Always exercise extreme caution when work­
ing under the hood ¢
page 191.
Overview
Some ind icator lights turn on briefly to check the
function of that system when you switch the igni­
tion on . These systems are marked with a./ in
the following tables .
If one of these indicator
lights does not turn on, there is a malfunction in
that system.

9:::1: Engine oil pressure
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se­
vere damage to the engine.
• Turn off engin e! Oil pressure too low
If the indicator light t urns on and the message
appears, the oil pressure is too low.
• Pull
off the road.
• Stop the vehicle .
• Turnoff the engine.
• Check the engine oil level ¢ page 195.
• If the engine oil level is too low, add engine oil
¢ page 195. Make sure that the o il pressure
warning symbol. appears no longe r in the
display before you start dr iving again.
• If the engi ne oil leve l is correct a nd the ind ica­
tor light st ill turns on, turn the eng ine
off and
do not continue driving . Seek p rofess ional as ­
s istance .
(D 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, prefe rably
each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay. Do not wait until the red oil pressure warning. starts to flash before
you respond to the low oil leve l warning
Ill . By then , your engine may already have
suffered serious damage.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢-4 in the
instrument cluster is part of the On-Board Diag ­
nostic (OBD II) system.
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunct ion may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelerations)

and have the condition corrected. Contact your
authorized Audi dea ler.
If t he light illuminates, the electronic speed lim­
ite r may also be ma lf u nctioning. For more infor­
mation

An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢

On-Board Diagnostics
Fig. 18 Locat ion of Data Link Connector (DLC)
On-Board D iagnost ics monitors the components
of your emission control system. Each monito red
component in your engine system has been as­
signed a code. In case of a malfunction, the com­
ponent will be ident ified and the fault stored as a
code in the control module memory.
T he MIL light may also illum inate if there is a
leak in the on-board fuel vapo r recovery system .
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed

In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the spec ial diagnostic equip­
ment, push the plug into the Data Lin k Connec tor

Driving
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat starting procedure.
When starting the engine, major elect rical loads
are switched off temporarily .
After a cold engine is started, there may be a
brief period of increased noise because oil pres­
sure must fi rst bui ld up in the hydraulic valve ad­
justers. This is normal and not a cause for con ­
cern.
.&_ WARNING
-~ ·
-Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehicle
has come to a complete stop.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed . This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on the ir own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.
CD Note
- Avo id high engine rpm, full throttle and
heavy eng ine loads until the engine has
reached operating temperature -otherwise
you risk engine damage.
@ For the sake of the environment
Do not let the engine run wh ile parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions .
@ Tips
-After starting a cold engine, there may be a
