a) Tips
The instrument illumination for the needles
and dials turns on when the ignition is turned
on and the lights are turned off. The illumina­
t ion fo r the dials reduces automatically and
eventua lly turns off as brightness outside in­
creases . This function reminds the driver to
turn the headlights on at the appropriate
time.
Engine coolant temperature gauge
The engine coo lant gauge (D Q page 10, fig. 3
only works when the ign ition is on. To prevent
10
damage to your engine, please note the follow­
ing important points:
Engine cold
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, heavy en­
gine loads and heavy throttle applications.
Normal temperature
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high . Th is is no need to worry as long as the.
warning light in the instrument cluster does not
ill uminate .
If the LEDs in the upper area of the
display and the indicator light. in the instru­
ment cluster display turn on, the coolant temper­
atu re is too high
Qpage 15.
A WARNING
-Always observe the warning in <9page 216,
before opening the hood and checking the
engine coolant level.

-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment. You
could burn yourself. Let the engine cool off
first until you can no longer see or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or h igh engine load, the engine cou ld
ove rheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spoiler is damaged, this
could red uce the cooling effect and the en­
gine could then overheat . Ask your author ­
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera ­
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other­
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.
In strum ents an d ind ic a to r ligh ts
Fuel level
The fue l gauge only works when the ignition is
on.
If t h e fue l level drops below 2.6 gallons (10
lite rs), the bottom LED turns red and the indica­
tor light
t]J turns on c::> page 21. The bottom
LED blinks red when the fue l level is very low.
T he possible range based on the c urrent fue l lev­
el is shown in tab@c::>
page 23, fig . 4 .
Fo r the tank capacity in your veh icle, refer to the
T echn ica l Data c::>
page 2 71.
CD Note
Never drive until the tank is completely emp­
ty. The irregu la r supply of fuel that resu lts
from that can cause t he engine to m isfire. Un­
combusted f uel w ill then en ter the exha ust
system . This can cause ove rheating and dam­
age to the catalytic converter.

9:::1: Engine oil pressure malfunction
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
Low-oil-pr essure indication is Likely to inflict se­
vere damage to the engine.
• Switch off engine and check oil level
If the indicator lig ht t urns on and the message
appears, the oi l pressure is too low.
~ P ull off the road.
~ Stop t he ve hicle .
~ Turnoff the engine.
~ Check the engine oil level¢ page 220 .
~ If the engine oil leve l is too low, add engine oi l
¢ page 220. Make sure that the oil pressure
warning symbol. appears no longe r in the
display before you s ta rt driving ag ain.
~ If the engi ne oil leve l is correct and t he i ndic a­

off and
do not continue d riving . Seek p ro fessional 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, preferably 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 level warning

tion:
Drive for approximately 15 minutes with these­
lector lever in the S position at a minimum speed
of 37 mph (60 km/h) and an engine speed of ap­ proximately 2,000 RPM. The temperature in­
crease that will result from this can burn off the

! 7l Engine speed limitation
A ppl ies to vehicles: with e ngin e s pee d l imitat ion
(II Engine speed maximum XXXX RPM
The engine speed is automatically limited to the
speed d isplayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
al.
If the engine speed limitation was activated by
an engine control malfunction, the~ indicator
light also turns on . Make sure that the speed
does not go above the speed d isplayed . Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifi in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignit ion 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 wh ile you are driving, a
28
malfunction 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 accelera­
tions) and have the condition corrected . Contact
your authorized Audi dea ler.
If t he light illuminates, the electronic speed lim­
iter may also be ma lfunctioning. For more infor­
mation ¢
page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connector (DLC)
On-Boa rd Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s ig ned a code . In case o f a malfunct ion, the com­
pon ent will be identified and the fault stored as a
code in the contro l module memory.
The MIL light may also illum inate if there is a
leak in the on-boa rd fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
c::;;, page 210.
In order to make an accu rate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD) .
In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
