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 the sake of the environment
Upshifting early saves fuel and reduces engine noise. •

To hide or display the date
- Pull the knob as many times as necessary until the date
display flashes .
- Turn the knob to the left or right.
When the date display stops blinking, this means the time and date
have been successfully stored.
With the ignition off, pushing or pulling the Set/Check button

ration - can turn on the display field lighting for a few seconds .•
Engine coolant temperature gauge
The engine coolant gauge~ page 12, fig. 2 © only works when the
ignition is on. To preven t damage to your engine, please note the
following 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
will move into the middle 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 -~- warning light in the instrument cluster does not illuminate.
When the
_J _ warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high , or the coolant
level is too low~ page 34. ~

Driver information system
Parking brake set
The parking brake warning light Brake /((D) (Canada models) illumi ­
nates when the parking brake is set. In addition , a warning tone will
sound after you have driven for longer than 3 seconds and faster
than 3 mph (5 km/h).
L1}. WARNING
• Always observe the warnings in => page 209, "Engine compart­
ment", before opening the engine hood and checking the brake
fluid.
• Driving with low brake fluid is a safety hazard! Stop the car and
get professional assistance.
• If the brake system warning/indicator light illuminates
together with the ABS warning/indicator light, then the ABS system is malfunctioning. The rear wheels could quickly lock up
when you apply the brakes. This could lead to loss of control and
your vehicle could slide! Drive carefully to the nearest authorized
Audi dealer and have the malfunction corrected. •
Engine cooling system malfunction ¾
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the _t symbol in the display flashes, then either the
engine coolant
temperature is too high, or the coolant level
is too low. In addition to the symbol, the following message
also appears in the display:
Switch off engine and check coolant level
-Pull off the road and stop the vehicle.
- Turn off the engine.
- Check coolant level
~ page 225.
-Add coolant if necessary ~ page 225.
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary .
If t he engine coolant lev el is correct, then th e radia tor fan may be
the cause of the malfunction.
If the gene rator warning/indicator light should also illuminate
=> page 18, then the fan belt may be damaged.
L1}. WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 57, "Emer­
gency flasher A" .
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn off
the engine and allow it to cool. Follow the warning stickers
=> page 209, "Engine compartment" .
0 Note
Do not continue driving if the-~- symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine .•

Warm and cold
Climate controls
Controls
The air conditioning automatically maintains the selected
temperature in the vehicleinterior throughout each
se ason.
F ig. 76 C limate contro ls
We recommend the following setting:
- Rotate the knob~ fig. 76@ to the right to switch on the
ai r conditioning.
- Set the temperature to 72 °F (22 °C).
- Press the !AUTO
j ~ fig. 76 button.
Con tro ls and eq uip­
ment
W arm and cold
Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle. This setting should
therefore only be changed when personal comfort levels or certa in
circumstances require it.
The climate controls are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and cools the air inside the vehic le .
The climate controls automatically maintain a temperature once it has been set. The temperature of the air from the vents, fan speed
(air volume) and air dist ribu tion are a lso automatically adjus ted . The
system also takes into account strong sunshine so that manual
adjus tment is not necessary. So in almost all cases,
a ut omatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 88.
Ple ase not e:
In cooling mode, relative humidity in the interior is reduced. This
prevents the windows from fogging up .
When relative humidity and temperatures outside are high,
conden ­
s ate
can drip from the air conditioning evaporator and form a pool
of water under the vehicle . This is normal and not an indication of a
leak!
When outside temperatures are low, the fan does no t switch to a
higher speed until the coolant has reached an adequate tempera­
ture, with the exception of t he defrost setting .
When accelerating at wide-open throttle, the air conditioning compressor is temporarily switched off to maintain fu ll engine
power.
In order to ensure engine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high ...

Starting and stopping the engine
Starting the engine
The engine can only be started with on original Audi key
and the clutch pedal* depressed.
- Set the parking brake.
Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
~ & .
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
0 ~ page 92, fig. 79 -
do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This normal
and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
Controls and equip ­
ment
On the road
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature. •
Stopping the engine
-Turn the ignition key to position G) ~ page 92, fig. 79.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up
in the engine
compartment. .,
