The illuminat ion for the instrument cluster lights up whenever you
switch on the ignition with the
v ehicle 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 coolant gauge ~ fig . 2 CD only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important points:
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 hig h
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 27. _,.

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 269, "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 tac home ter @ => page 8, fig. 2 is the left of the two large cloc k­
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 24.
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). •
Electronic power control C
This warning/indicator light monitors the electronic
power control.
The warn ing/indicator light (Electro nic Power Control) illumi-
nates when you turn on the ignition as a function check .
(I] Tips
If this warning/indicator light illuminates while you are driving, then
there is a malfunct io n in the engine electron ics . Have the ma lfunct io n
corrected as soon as possib le by your authori zed Audi dealer or qual­
ified repair fac ility. •
Electronic stabilization program (ESP) ,,. ..
This warning/indicator light monitors the electronic
stabilization program.
T he warn ing/indicator lig ht has the follow ing funct ions:
• It blinks while you are driving when the ESP is working.
• It illumina tes when you sw itch on the ignition fo r approximately 2
seconds as a function check .
• It illuminates whe n there is a malfunction in the ESP .
• It illuminates when ESP or ASR (Ant i-Slip Regula tion) is deacti­
vated .
• It ill umina tes if t he re is a malfunction in the A BS, s ince the ESP is
part of the ABS system. If the battery terminals were disconnected and re-connected, the
vehicle was jump st arted o r th e bat tery is very weak, t he ESP se nsor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates. The war ning/indicator light goes
out as soo n as the learning process is complete .
If the ESP warning/indicator light ill uminates and stays on after yo u
have sta rted t he engine, t his may mean that the co ntrol system has
temporarily switched off the ESP . If this is case , you can react ivate
t he ESP by tu rning the igni tion off and t hen o n ag ain . The
warning/indica tor light should go out to show that the system is fully
functional again.

& WARNING
• USA models: If the BRAKE warning light and the r i,~ warning
light come on together, the rear wheels could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop . Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light (CD) and the ABS
warning light :::; come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock -up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­ di ately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected.
• Always keep in m ind that after several brake applications , you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brakes to respond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •

& WARNING
• Never rely exclusively on the outside temperature display to
determine if a road surface is icy or not . Keep in m ind that road
su rfaces , especially bridges and overpa sses, could be ice covered
and slippery even at an outside temperature above 41 °F (+5 °C ).
• Always remember , even if the "snowflake" symbol (ice
warning ) does not appear in the di splay, black ice could be on the
road.
• Always reduce your speed and drive with special care in cold
weather conditions when the chance of encountering icy road
surfaces increases.
(I] Tips
If the vehi cle is stat io na ry, or if yo u are driv ing at a very low speed, the
temperature shown in the display m ight be slightly higher than the
