The illum inat ion for the instrument cluster lights up whenever you
switch o n the ignition with the
vehicle headlight s off. As the daylight
fades, the instrument cluste r illum ination likewise d ims automati­
cally and w ill go out completely when the outside light is very low .
T his featu re is mean t to remind you to switch on the headligh ts when
outs ide light conditions become poor .•
Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the need le remains at the le ft end of the gauge, the engine
st ill has not re ached its operating tem perature. Avoid high eng ine
speeds, heavy engine loads and heavy throttle applicat ions.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
go furthe r to the right. This is no need to wo rry as long as the _JL
wa rning light in t he instrument cluster does not illuminate .
Warning light in the instrument cluster -t
When the _ L warning light starts to flash, this ca n mean one of two
t hings: e ither the cool ant
temperature is too h igh, or the coolant
level is too low=> page 29. _,.

If the indicator goes all the way to the right side inside the coolant
t empe ra tu re ga uge, the n th e eng ine cool ant tempe rature is too high.
Pull off the road to saf e location , turn off the engine and let it cool
down.
If the warning lig ht comes o n aga in after yo u have driven a
short distance, contact a qualified workshop.
& WARNING
• Always observe the warning in ::::> page 281 , "Engine compart­
ment ", before opening the hood and checking the engine coolant
l e vel.
• Never open the engine hood if you see or hear steam, or if you
see engine coolant dripping from the engine compartment. You
c ould burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in front of the a ir in lets
reduces the cooling effect of the radiator. At high outside tempe ra ­
tu res o r high engine load, the e ng ine could ove rheat .
• T he front spoi le r has bee n designed to properly distribu te the
cooling air when the vehicle is moving . If the spoiler is damaged, this
co uld reduce the coo ling effect and the eng ine could then overheat.
Ask your author ized A udi deale r for assistance. •
Tachometer (engine rev counter)
The tac home te r indicates the engine RPM (revoluti ons
pe r minu tes) .
The tachometer @::::> page 10, fig. 2 is the left of t he two large clock­
type displays .
Th e eng ine tu rns at a speed
1,000 times t h e si ng le dig it in t he
display, e .g. if the need le is pointing at the "2" the engine is tu rning
at 2, 000 R PM.

ment Safety first

If e ngine RPM drops below 1,500, you s hould dow nsh ift to t he next
lower ge ar. T he re d area at t he e nd of the s cale i ndic ates m aximum
permissible e ngine RPM after the break-in per iod . Before reaching
this area, move the selector lever to posit ion "D (Drive)" or ease yo ur
foot off the accelerator pedal.
0 Note
The tachome ter needle s houl d not move in to the red range. If it does,
then only fo r a very short period of time . You could damage your
e n g in e by driv ing at h igh RPM .
c£> For the sake of the environment
Upshifting early saves fuel a nd reduces e ngine noise. •
