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.

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 .

c lu st er: ce nte r dis play
The driver information display is located in the center of the instru­
ment
cluster:::> fig. 10.
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
nd sys te m and
n av igatio n
systems are being used.
Detailed instructions for operating the Aud i Naviga tion System* are

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
information=> page 28, "Electronic speed
limiter".

On -Board Diagnostics
F ig. 15 Locatio n of
Da ta Li nk Co nnecto r
( DL Cl
On-Board Diagnostics monitors the components of your emission
control system . Each control led component in your engine system
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
modu le memory.
The M IL lamp may a lso illuminate if there is a leak in the on-board
fuel vapor recovery system. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel fi ller
cap is proper ly closed
=> page 269.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnos tic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood release
lever => fig. 15 .
Your author ized Audi dealer or a qua lified service station can inter­
pre t the code and perform the necessary repair. •
irechnical data

Driver information display
-Check coolant level :::> page 281.
-Add coolant if necessary=> page 282.
-Continue driving only after the engine coolant
warning/indicator light goes out.
-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
I f the generator warning/indicator light should also illuminate
=> page 22, then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 79, "Emer­
gency flasher
A" .
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded .
Wait until you can no longer see or hear steam or coolant escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 265, "Engine compartment" .
0 Note
Do not continue driving if the-~-symbol illuminates. It indicates a
cooling system malfunction likely to result in serious damage to the
engine. •
Engine oil pressure malfunction ~
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the 9=::;,. symbol appears in the display and blinks, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
Switch off engine, check oil level
Immediate actions
-Pull off the road and stop the vehicle.
-Shut the engine down.
-Check the engine oil level with the dipstick=> page 277.
Dipstick reading checks too lovv
-Top off oil to the proper level => page 278.
-Make sure that the oil pressure warning symbol 9=::;f.
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
-If the 9=::;f. symbol starts flashing again even though the
engine oil level checks OK on the dipstick,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis-
tance.
.,_

[ i J Tips
• The engine oil pressure symbol ~ is not an indicator for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular interval s, preferably each time you refuel , and
always before going on a long trip.
• The yellow oil level warning indication requires oil refill or
workshop service without delay . Do not wait until the red oil pre s­
s ure warning symbol
~ starts to fla sh before you respond to the
low oil level warning
-... . By then , your engine may already have
s uffered serious damage. •
