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 35. _,.

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 290 , "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
e n g in e by driv ing at h igh RPM .
c£> For the sake of the environment
Upshifting early saves fuel a nd reduces e ngine noise. •

Instruments and warning /indicator lights
(I] Tip s
Many fun ct ions a re mon itored by the Auto-Check system=> page 32.
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 (E lectronic 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) ~ / t:.
This warning/indicator light monitors the electronic
stabilization program .
If the indicator lamp blinks w hile driving, the ESP or ASR (Anti-Slip
Regulation) is actively regulat ing .
If the ~ indicator lamp illuminates, the system has switched the ESP
off. In this case , you ca n swi tch t he ignition off and then on to swi tch
the ESP on again. The system is functioning completely when the
ind icator lamp sw itches off.
If the ind icator lamp illuminates, the ESP was switc hed off w ith the
I~ OFF! button .
ESP/ ABS fault ! See own er' s manual
If the • indicator lamp and the ~ ABS indicator lamp illuminate and
the d river message appea rs, the ABS or e lectronic differentia l lock is
ma lfunction ing . This also interrupts the ESP . The brakes still funct ion
w ith their normal power, but ABS is not act ive .
Dr ive to your author ized A udi deale r immediately to have the
malfunction corrected.

on the instrument panel dur ing the trip=>
page 35, then you have to
stop immediately and turn off the engine. The coolant pump is not
working anymore -danger of damage to the engine! •
