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.

Defective light bulb warning ~
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol wi th a message appears in the display to
tell you which bulb is burnt out and where it is located . For example :
REAR LEFT TURN SIGNAL
After 5 seconds, the message d isappears . If you want to reca ll the
message into the display, press the CHECK button.
There are three reasons why the defective bulb message wou ld
appear in the display:
• the light bulb has burnt
out => page 328.
• the fuse is "blown"=> page 326, "Replacing a fuse" .
• the wire connec tion to the light bulb is defective .
Have the bulb replaced or the connection repaired by your autho­
rized Audi Service department .

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a
set speed limit.

irechnical data

Driver inf orma tion di spl ay
The speed warning system warns the driver if he exceeds a previ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehic le speed exceeds the set speed by about 6 miles per hour
(10 km/h) . At the same time, a warning symbol appears in the
display~ fig. 21 .
The speed warning system has
t wo wa rning thre sholds that func ­
tion independent ly of each other and that have somewhat different
purposes:
Sp eed w arnin g 1 -
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol (USA models)/ (: (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low the stored maximum
speed .
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is de leted.
Setting speed warning 1
~ page 36 .
S pee d w arni ng 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a genera l maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, (USA models)/ (Canada models) appears in the disp lay when you exceed the stored speed limit .
Unlike warning 1, it wil l not go out until the vehicle speed drops
below the stored speed limit .

~ page 37.
[ i ] Tip s
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed l imit. •

about ten minutes after the ignition is switched off. Only when
either of the front doors are opened are the power windows
switched off.

is in the way, or serious injury could result!
• Always remove the ignition key whenever you leave your
vehicle.
• If you lock your vehicle from the outside, no one, especially chil­
dren, should remain in the vehicle.
• Do not stick anything on the windows or the windshield that
may interfere with the driver's field of vision. •

[ i] Tips
The windows can still be opened and closed for about ten minutes
after the ignition has been turned off. The power windows are not
shut off until one of the front doors is opened .•

& WARNING
Never use daytime running lights to see where you are going . They
are not bright enough and will not let you see far enough ahead for
safety , espe cially at dusk or when it is dark . Be aware of changes
in outside light conditions when you are driving and respond by
switching on your lo w beams
io.
0 Note
• With the light switch at the O or :oo, position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instruments appear well lit, the road ahead of you is not. The light pattern provided by fog lights alone is not sufficient for safe
driving in poor light or darkness. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the
light switch to position
io (or "AUTO" if your car is equipped with
th is featu re)
to turn on your headlights .•

the intermittent wiping mode .
To reduce the sensitivity of the sensor, move switch @down . To
inc rease the sensitivity, move the switch up. The higher you adjust
the sensitivity, the faster the sensor will react when it senses mois ­
ture on the windshield. The pauses between wiper turns depend not only on the sensitivity setting, but on the vehicle speed as well.
The rain sensor wiper interva ls depend on the sensitivity setting as
we ll as vehic le speed. During brief stops, wiper motion will adjust to
the amount of rain on the w indshield.
When the ignit ion is turned on, the washer jets are heated .
With the low beam headlights switched on, pull the wiper lever
towards you only
briefly to c lean the windshield. Ho lding the wiper
lever would also engage the headlight washer system* each time
you clean the windshield and would drain the washer fluid reservoir
prematurely.
