The illum inat ion for the instrument cluster lights up whenever you
switch o n the ignition with the
vehicle headlight s off. As the daylight
fades, the instrument cluste r illum ination likewise d ims automati­
cally and w ill go out completely when the outside light is very low .
T his featu re is mean t to remind you to switch on the headligh ts when
outs ide light conditions become poor .•
Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the needle rema ins at or close to the bottom of the gauge,
t he engine s till has not rea ched its operat ing tem perature. Avo id high
eng ine speeds, heavy eng ine loads and heavy t hrottle app lications.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
r ise up. This is no need to worry as long as the
_t_ warning light in th e
instr ument cluster does not illuminate.
Warning light in the instrument cluster -t
When the _L warning light in the instrument cluster starts to flash,
this can mean one of two things: e ithe r th e coolan t
temperature is
too high, or the coolant
level is too low=> page 30. _,.

If the needle is well in the upper area of the gauge, the coolant
tempe rat ure is too high.
Stop the vehicle , switch the engine off and
allow the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Alway s observe th e warning in=> page 286 , "Engine comp art ­
ment ", before opening the hood and checking the engine coolant
level.
• Never open the engine hood if you see or hear steam, or if you
s ee engin e coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­
t ur es o r high engine load, the engine could overheat.
• The front spo iler has bee n des igned to prope rly d istribute the
coo ling air when the vehicle is moving.
If the spoiler is damaged, this
cou ld reduce the coo ling effect and the eng ine could then overheat .
Ask your author ized A udi dealer for assistance .•
Tachometer (engine rev counter)
The tachometer indicat es th e engine RPM (revolutions
per minutes).
Th e ta chomete r@ ::::> page 1 0, fig. 2 is the left of the tw o large clock­
type displays.
Th e engine tu rns at a speed
1,000 times the si ng le dig it in the
display, e.g. if the need le is po int ing at the "2 " the engi ne is t urning
at 2,000 RP M.

If e ngine RPM drops below 1,500, you s hould dow nsh ift to t he next
lower ge ar. T he re d area at t he e nd of the s cale i ndic ates m aximum
permissible e ngine RPM after the break-in per iod . Before reaching
this area, move the selector lever to posit ion "D (Drive)" or ease yo ur
foot off the accelerator pedal.
0 Note
T he tachome ter needle s houl d not move into the red range. If it does,
then only fo r a very short period of time . You could damage your

Instruments and warning /indicator lights
(I] Tip s
Many fun ct ions a re mon itored by the Auto-Check system=> page 2 7.
Malfunctions or faults will be identified either with a red symbol
(pr iority
1-Dange r!) or w ith a ye llow symbo l (prio rity 2 -Warn ing). •
Applies to veh icles: w it h gasoline eng ine
Electronic power control ~
This warning/indicator light monitors the electronic
power control.
T he warning/indicator light (El ectronic Power Control) illumi-
nates when you turn o n the ignition as a function chec k.
[ i ] Tips
If this warning/indicato r light ill uminates while you are driving, then
there is a malfunct ion in the engine e lectron ics . Have the malfunct ion
co rrected as soon as possib le by yo ur autho rized Audi dealer or qua l­
ified workshop .•
A pp lies to ve hicles : w ith d iese l en gi ne
Glow plug system
The control light illuminates when the glow plug system
is active.
If the indicato r ligh t illum inates, the g low p lug system is active .
You should start the eng ine immed iate ly after the ind icator light
switches off. The ind icator ligh t only illumina tes for approximately 1
second if the engine is warm or if the outside temperature is above 46
2F (8 2C).
(I] Tips
• If the glow plug indicator light illuminates while driving, there is
an engine control malfunction. The engine should be checked imme­
diately .
• If the indicator light does not ill uminate at all when switching the
ign ition on, the re may be a ma lfunction in the glow plug system. The
engine should be checked .•
Electronic stabilization program (ESP) ;
This warning/indicator light monitors the electronic
stabilization program .
The warn ing/indicator light has the fo llowing funct ions:
• It blinks while you are driv ing when the ES P is wo rking.
• It illuminates when you switch on the ignition for approximate ly 2
seconds as a funct ion check .
• It ill uminates when there is a malfunction in the ESP .
• It illuminates when ESP or ASR (Ant i-Slip Regulation) is deacti­
va ted .
• It illuminates if there is a malfunction in the ABS, s ince the ESP is
part of the ABS system.
If the battery terminals were disconnec ted and re-connected, the
vehicle was jump started or t he battery is very weak, the ESP sensor
system goes through a learning process for the fi rst few yards. The
warning/indicator light illuminates. The warning/indicator light goes
out as soon as the learning process is comp lete .
If the ESP warning/indicator light illuminates and stays on after you
have sta rted the e ngine, t his may mean that the control system has
temporarily switched off the ESP . If this is case, you ca n react ivate
t he ESP by turning the igni tion off and t hen on aga in . The
warning/indicator light should go out to show that the system is fully
functional again. _,,,

& WARNING
Always observe the post ed speed limits and adjust your speed to
s uit prevailing road , traffic and weather condition s. Never drive
your vehi cle faster than the m aximum sp eed rating of the tires
installed .•
