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.

Starting the Auto-Che ck sequence
The Auto -Check
system => page 28 consistently monitors certain
individual functions and components of the vehicle when the igni­
tion is turned on and when the vehicle is moving .
With the ignition switched on, you can start the "Auto-Check
sequence" by pressing the CHECK button. You can perform an Auto ­
Check sequence both when the vehicle is at a standstill and the igni­
tion is switched on or when the vehicle is moving not faster than
3 mph (5 km/h).
Calling up the driver informat ion
When a first priority symbo l starts to
flash => page 28 or when a
defective light
bulb=> page 35, has been detected, you can press
the CHECK button to display the driver information. For example:
SWITCH OFF ENGINE , CHECK OIL LEVEL
The information disappears after approximate ly five seconds .
Setting the speed warning
By pressing the CHECK button you can set speed warning
1
=> page 36, "Speed warning 1: setting a speed limit" while the

Fig. 8 Service interval
display in the instru­

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 .
