The illumination for the instrument cluster lights up whenever you
switch on the ign ition with the
ve hicle hea dlight s off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and wil l go out completely when the outside light is
very low. This feature is meant to remind you to switch on th e head ­
lights when outside light conditions become poor. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes) .
The tachometer 0 ~ fig. 2 is the left of the two large c lock -type
displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g . if th e ne edle is pointing a t the
"2" the engine is turning
at 2,000 RPM .
If engine RPM drops below 1,500, you should downshif t to the next
lower gear . The red ar ea at the end of th e scale indica tes maximum
permissible engine RPM after the break- in period. Before reaching
th is area , shift into the next higher gear (manua l transmission),
move the selec tor lever to position "D (Drive)" (automatic) or ease
your foot off the accelerator pedal.
0 Note
T he tachometer need le should not move into the red range . If it
does, then on ly for a very short period of time . You could damage
your engine by driving a t high RPM. ...

For example, the display can tell you how many
miles (kilometers) you can still drive until it is time to bring your
vehicle to your authorized Audi dealer for a scheduled Maintenance Service . This feature helps preventing costly repairs. It is just one of
many different items of information availab le for recall. The display
a lso gives you a "status report" whenever the
so und s ystem , tel e­
ph on e, a nd navi gation
systems are being used.
Detailed instructions for operating the Audi Navigation System* are provided in separate manuals . The Driver Information System provides the following functions:

[ i] Tips
• Do not reset the display between service intervals. Doing so will
result in an incorrect display.
• If service was not performed at the correct time or the service
interval display was not reset after service was performed, the addi ­
tional mileage driven or the elapsed days will be shown as negative
numbers.
• If the battery is disconnected, the Service Interval Display values
are retained.
• If a priority 1 malfunction is present (red symbol), the distance
remaining cannot be called up. •
