The illumination for the instrument cluster lights up whenever you
switch on the ignition with the
vehicle headlights off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and wil l go out complete ly when the outside 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 the needle remains at the left end 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
will move into the middle of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may go further to the right. This is no need to worry as long as the
-~-warning light in the instrument cluster does not illuminate.
Warning light in the instrument cluster -L
When the _L warning light 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 31. _.,

If the indicator goes all the way to the right side inside the coolant
temperature gauge, then the engine coolant temperature is too
high.
Pull off the road to safe location, turn off the engine and let it
cool down.
If the warning light comes on again after you have driven
a short distance, contact a qualified workshop.
& WARNING
• Always observe the warning in :::::, page 299, "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 12, 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.
Controls and equip­ ment
Instruments and warning/indicator lights
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 MM/.

clock
The date, time of day, and time and date format can be set in MMI.

Instruments and warning /indicator lights
-Press the"-" button to decrease the brightness during
the hours of darkness.
A light sensor in the instrument cluster controls the illumination for
the instrument clust er, the center console and the displays . In a
bright environment , using the buttons to change the brightness has
no effect .
[ i] Tips
The illumination for the instrument cluster lights up whenever you
switch on the ignition with the
vehicle headlights off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and will go out completely when the outside light is
very low. This feature is meant to remind you to switch on the head­
lights when outside light conditions become poor. •

[ i] Tips
Many functions are monitored by the Auto -Check system
=> page 28 . Ma lfunctions or faults wil l be identified either with a red
symbo l (pr iority 1
-Danger!) or with a yel low symbol (priority 2 -
Warning) .•
Electronic power control EPC
This warning/indicator light monitors the electronic
power control.
The EPC warning/indicator light (Electronic Power Control) i llumi ­
nates when you turn on the ignition as a function chec k.
[ i ] Tips
If this warning/indicator l ight i lluminates whi le you are driving, then
there is a malfunction in the engine electronics . Have the malfunc­
t ion corrected as soon as possible by your authorized Audi dea ler or
qualified repair facility .•
Generator D
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
igni tion and must go out a fter 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 vehic le battery is discharging, you should switch off any unnecessary elec
­
t rical consumers (for example, the air conditioner).
0 Note
If the _f_ warning/indicator light (ma lfunction in the engine coo ling
system) in the instrument cluster shou ld
illuminate=> page 31, stop
the vehicle and turn off the engine . The water pump is not working
-this can cause engine damage. •
Electronic stabilization program (ESP) f1.
This warning/indicator light monitors the electronic stabi ­
lization program.
Th e 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 approximate ly
2 seconds as a function check.
• It illuminates when there is a malfunction in the ESP. The
message
ESP fault! See owner's manual also appears in the instru­
ment cluster display and a warning tone sounds .
• It illuminates continuously when the ESP is switched off.
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS sys tem.
If the battery terminals were disconnected and re-connected , the
vehic le was jump sta rted or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates. 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
temporarily switched off the ESP . If this is case, you can reactivate
th e 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.
For more information about the
ESP=> page 268. •
Airbag system C:,
This warning/indicator light monitors the airbag and the
tensioner systems.
The ffi warning light illuminates for a few seconds each time you
switch on the ignition.
If the m 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 some ­
where 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. •
