The instrument cl uster and center console
illumi nat io n (gauges and need les) c omes
on when you switch on the ignition and the
vehicle headlights are off . Be aware o f the
f ollowing diffe re nc e betwee n mode ls built
t o US or C ana di an specific ati ons :
-USA models: illumination of the instru­
ment clu ster (gauges and needles),
dash and center console around the
gearshift lever is controlled by a light
sensor located in the instrument panel.
The instrument panel illumination will automatically become dimmer as the daylight fades away and eventually will
go out completely when outside light is
very low . This is to remind you, the driv­
er , to switch on the headlight s before it
gets too dark.
- Canada model s: instrum ent pan el illu­
mination will stay bright regardless of
the intensity of ambient light. Always be aware of changes in out side light
conditions while you are driving. Re­
spond in time to fading daylight by
turn ing the light switch to position
iD
(or ,;AUTO" if your car is equipped w it h
this feat ure)
to turn on your headlights .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer CD c> page 10, fig. 3 is the left
one of the two large clock-type d isplays.
T he eng ine turns at a speed
1 000 times the
s ingle digit in the display, e.g . if the needle
po ints at the "2", the engine t urns at
2000RPM. ~

Instrument s and warning /indicator lights 11
If the engine RPMs drop below 1 500, you
should downshift to the next lowe r gear . The
red area at the end of the scale indicates max­
imum permissible engine RPMs after the
break-in per iod. Before reaching this area, you
should either shift i nto the next h igher gea r or
ease your foot off the accelerator pedal.
(D Note
The tachometer needle¢ page 10, fig. 3
@shou ld not move into the red range. If
it does, then o nly for a very sho rt period of
t ime. You cou ld damage yo ur eng ine by
driving at high RPM !
@ For the sake of the environment
Upshift ing early saves fuels and red uces
eng in e no ise.
Digital clock with date display
Your vehicle is equipped with a quartz con ­
trolled digital clock .

Engine coolant temperature gauge
T he eng ine coolan t ga uge @ ¢ page 10, fig . 3
o nl y works when the ignition is on. To p revent
damage to your engine, please note the fol­
l owing important points:
Engine cold
As long as the nee dle remains a t the left end
of the gauge, the engi ne s till has not reac hed
its operatin g tem perat ure. Avoid hig h eng ine
speeds, heavy engine loads and heavy throt ­
tle .
Normal temperature
When the engine has reache d its ope ra ting
temperature, the need le w ill move into the
midd le of t he gauge and rema in there . If t he
engine is working hard at high outside tem­
peratures, the need le may tur n further to the
right. This is no cause for concer n as long as
the . warn ing light i n the instrument cluster
does not illuminate .
When the. war ning light starts to flash,
th is can mean one of two things: either the

12 Instrum ents a nd warning /indic ato r li ghts
coolant temperature is too high, or the cool­
ant
level is too low ¢ page 17.
.&_ WARNING
- Always observe the warning in
¢ page 187, Engine compartment be­
fore opening the engine hood and check­
ing the engine coo lant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the eng ine 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 l ights or accesso ries
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator. At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo ile r has been designed to
properly distrib ute the cooling air when
the veh icle is moving.
If the spoiler is
damaged, this cou ld reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dea ler for
assistance.
Fuel gauge
The fuel gauge works only when the ignition is
on.
When the needle reaches the red area, the
warning light in the instrument cluster will il­
lum inate <=>
page 21 lil This means you
have approximately
1.8 gallons (7 liters) of
fuel left in the tank .
Time to re fu el!
The total tank capacity of your vehicle is listed
in¢
page 257, Data.
(D Note
Never run the tank completely dry! An ir­
regular supply of fuel can cause eng ine
m isfiring and fuel could enter into the ex­
haust system. The catalyt ic converte r
could then overheat and be damaged.
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven.
F ig . S Speedometer close- up: odom eter display
The odometer and trip odometer are located
inside the speedometer .
- USA models -Miles
- Canadian models -Kilometers
Lower odometer
The lower odometer shows the total number
of miles (kilometers) driven.
Uppe r odometer (trip odome ter)
The upper odometer shows the total number
of miles (kilometers) driven since you last re­
set the odometer back to zero. You can use
th is odometer when you want to keep track of
how many miles (kilometers) you have driven
for a single tr ip or errand. The last digit ind i­
cates 1/10 of a mile (100 metres) . You can set
the tr ip odomete r back to zero by pressing the
rese t button
c:> fig. 5.
Malfunct ion me ssage
If there is a malfunct ion somewhere in the in­
strument cluster,
dEF w ill appear in the trip
odometer and w ill stay on . Contact your au­
thorized Audi dea ler to have the problem cor­
rected.
