The instrument cluster illuminates whenever you switch on the ign i­
tion with the
vehicle headlights off. The instrument cluster illumina­
tion dims automatically as the daylight begins to fade away . It goes
out completely when the outside light is very dim . The reason for
this is to remind you to turn on the headlights when the light condi ­
tions become poor.
•
Engine coolant temperature gauge
The engine coolant gauge 0~ page 12, fig . 2 only works when the
ignition is on. To prevent damage to your engine, please note the
f o llowing 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 .
Normal temperature
When the engine has reached its operating temperature, the needle
wi ll move into the midd le of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may turn further to the right. This is no cause for concern as long as
the
J_ warning light in the instrument cluster does not illuminate.
When the
_t_ warning light starts to flash, this can mean one of two
th ings : either the coolant
temperature is to o high, or the coolant
level is too low~ page 31 .
& WARNING
• Always observe the warning in ~ page 265, "Engine compart­
ment" before opening the engine hood and checking the engine
c oolant level .
Controls and equip ­
ment
Instruments and warning /indicator lights
& WARNING (continued )
• 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 coo ling effect of the radiator . At high outside tempera ­
tures or high engine load, the engine cou ld overheat.
• The front spoi ler 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 author ized 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 one of the two large
c lock -type displays.
The engine turns at a speed
1,000 times the sin gle digit in the
display, e .g . if the needle points at the "2", the engine turns at
2,000 RPM.
If the engine RPMs drop below 1,500, you shou ld downshift to the
next lower gear. The red area at the end of the scale indicates
maximum permissible engine RPMs after the break-in period.
Before reaching this area, you should either shift into the next
higher gear or ease your foot off the accelerator pedal.
.,_

Instruments and warning/indicator lights
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!
Upshifting early saves fuels and reduces engine noise .•

With the ignition on, briefly push button G) to disp lay the distance
remaining (miles/kilometers) until the next service is due. You can
recall the service countdown with the engine in idle or while driving
at a slow speed up to
3 mph (5 km/h). The remaining distance will
be upda ted every 300 miles (500 km):
On a new vehicle, or immediately after a service has been
performed, the following message will be displayed:
SERVICE IN---- Ml (KM) ---DAYS
For the first 300 miles (500 km) of driving after a service, the display
will keep showing dashes. This
is NOT a malfunction . Rather, the
system needs the mileage to (re-)adjust to your driving
style. Only
then can it start generating and updating figures for the distance and
days until the next scheduled service .

The ~ warning/indicator light has the fol lowing functions:
• it flashes while you are driving, when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a funct ion check.
• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected .
• it illuminates continuous ly when the ESP is switched off . •
it illuminates if there is a malfunction in the ABS, since the ESP
is part o f the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporar ily switched o ff the ESP . If this is case, you can reactivate
the ESP by switching the ignition off and then on again . The
warning/indicator light should go out to show that the system is
ful ly functional again .
I f the battery terminals were disconnected and re -connected, the

c lu st er: ce nte r dis play
The driver information display is located in the center of the instru­
ment

The driver information system updates important information in the center display in clear view of the driver . In an easy to understand
format, the display tel ls you how your vehicle is functioning
at th e
c urr ent m om ent .
For example, the display can te ll you how many
miles (ki lometers) you can still drive until it is time to bring your
vehic le to your authorized Audi dealer for a scheduled Maintenance
Service. This feature helps preventing costly repairs. It is just one of
many different items o f information available for recall. The display also gives you a "status report" whenever the
sou

n av igatio n
systems are being used.
Detailed instructions for operating the Aud i Naviga tion System* are
provided in separate manuals.

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 19, fig. 9 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light il luminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . This indicates that the MIL is working prope rly.
If the light do es not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light starts flashing, the catalytic converter could be damaged .
Continue driving
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the e lectronic speed limiter may also be
malfunctioning . For more

Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h}. This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive speeds, your vehicle also has an electronic speed limiter . The elec ­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating. For more
information~ page 305, "New tires and
r eplacing tires and wheels" .
If the vehicle approaches the tire speed rating, the engine control
unit wi ll turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals,
t he Malfunc tion Indicator Light (MIU will illuminate. If this occurs,
contact the nearest authorized Audi dea ler for ass istance.
