The illumination for the instrument cluster lights up whenever you
switch on the ignition with the
vehicle headlights off. As the
day light fades , the instrument c luster illumination likewise dims
automatically and will go out completely when the outsid e light is
very low. This feature is meant to remind you to switch on the head ­
lights when outside light conditions become poor. •
Engine coolant temperature gauge
The engine coolant gauge => fig. 2 G) only works when the ignition
is on. To prevent damage to your engine, please note the following
important points:
Engine cold
As long as th e needle remains at or close to the bottom of the
gauge, the engine still has not reached its operating temperature .
Avoid high engine speeds , heavy engine loads and heavy throttle
applications.
Normal temperature
When the engine has reached its operating temperature, the needle
wi ll move into the middle of the gauge and rema in there. If the
eng ine is working hard at high outside temperatures, the needle
may ris e up . This is no ne ed to worry as long as the
_f_ warning light
in the ins trument cluster does not illuminate . .,
Vehicle care I I irechnical data

Instruments and warning/indicator lights
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: either the coolant
temperature is
too high, or the coolant
level is too low~ page 33.
If the needle is well in the upper area of the gauge, the coolant
temperature 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
• Always observe the warning in ~ page 289, "Engine compart­
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
see engine 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 additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator. At high outside tempera­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving. If the spoiler is damaged,
this could reduce the cooling effect and the engine could then
over­
heat. Ask your authorized Audi dealer for assistance. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes).
The tachometer 0 ~ page 13, fig. 2 is the left of the two large clock ­
type displays. The
engine turns at a speed
1,000 times the single digit in the
display, e.g. if the needle is pointing at the "2" the engine is turning
at 2,000 RPM.
If engine RPM drops below 1,500, you should downshift to the next
lower gear. The red area at the end of the scale indicates maximum
permissible engine RPM after the break -in period. Before reaching
this area, move the selector lever to position "D (Drive)" or ease your
foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range. If it
does, then only for a
very short period of time. You could damage
your engine by driving at high RPM .
'£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
Digital clock with date display
Date and time of day can be set in the MM/.
Fig . 3 Instrument
cluster with digital
clock
The date, time of day, and time and date format can be set in the
MMI. You can find out more in the MMI manual. .,_

gallons (7 -9 liters) of fuel left . This message is meant to remind you
t o
r e fu el.
The to tal tank capacity of your vehicle is listed in:::, page 363.
0 Note
Never run the tank completely dry . An irregular supply of fuel can
cause engine misfiring and fuel could enter the exhaust system . The
cata lytic converter could then overheat and be damaged .•

"Engine compartment".
[ i ) Tips
Many functions are monitored by the Auto -Check system
=>
page 30. Malfunctions or faults wil l be identified either with a red
symbo l (pr ior ity 1 -Danger!) or with a yellow symbol (priority 2 -
Warning). •
Electronic power control r
This warning/indicator light monitors the electronic
power control.
The warning/indicator light (E lectronic 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 malfunction in the engine electronics . Have the malfunc ­
tion corrected as soon as possible by your authorized Audi dealer or
qualified repair faci lity .•
Generator 0
This warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system.
The d warning/indicator light illuminates when you switch on the
ign ition and mus t go out after the engine has started .
If the
d warning/indicator light illuminates while you are driving,
you shou ld contact your authorized Audi dealer. Since the vehicle
Controls and equip ­
ment
Instruments and warning /indi cator lights
battery is discharging, you shou ld switch off any unnecessary elec ­
trical consumers (for examp le, the air conditioner).
0 Note
If the _f_ warning/indicator light (malfunction in the engine coo ling
system) in the instrument cluster shou ld illuminate=>
page 33, stop
the vehicle and turn off the engine . The water pump is not work ing
- this can cause engine damage. •
Electronic stabilization program (ESP)
This warning/indicator light monitors the electronic stabi ­
lization program.
The warning/indicator light has the following functions:
• I t blinks while you are driving when the ESP is working.
• It illuminates when you switch on the ignition for approximately
2 seconds as a function check.
• It il luminates when there is a malfunction in the ESP.
• It illuminates when ESP or ASR (Anti-S lip Regulation) is deacti­
vated .
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the battery terminals were disconnected and re-connected, the
vehicle was jump started or the battery is
very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light i lluminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
te mporarily switched off the ESP. If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The
warning/indicator light should go out to show that the system is
fully functional again.

Airbag system
~ (USA models) / !_q· (Canada models)
This warning/indicator light monitors the airbag and the
tensioner systems.
The I (USA mode ls) t!l (Canada models) warning light illuminates
for a few seconds each time you switch on the ignition .
If the m (USA models)
t!.! r (Canada models) warning light does not
go out, or if it illuminates while you are driving, or if it starts to blink,
then there is a malfunction somewhere in the system. If the light
does not illuminate when you switch on the ignition, this also
means there is a malfunction.
& WARNING
If you have a malfunction in the airbag system, contact your autho­
rized Audi dealer immediately. Otherwise the airbag or the belt
tensioner may not work properly in an accident . •
Tire pressure monitoring system -telltale
indicator lamp
J
The warning/indicator light appears in the event of a
significant loss of air pressure.
The i warning/indicator light il luminates for a few seconds after
the ignition is turned on as function check and then goes out.
If the .., symbol appears, pressure is too low in at least one tire.
When the system detects a malfunction, the warning/indicator light
wil l flash for approximately one minute and then remain continu­
ously illuminated . This sequence wi ll continue upon subsequent vehicle starts up as long as the malfunction exists. Contact your
authorized Audi dealer and have the malfunction corrected.
For more information =>
page 44. •
Turn signals ¢ ¢

The Malfunction Indicator Lamp (MIL) is part of the On-Board Diag­
nostic (08D Ill system . The symbo l lights up when the ignition is
turned on and will turn off after the engine has started and has
settled at a constant idle speed. This indicates that the MIL is
working properly.
