The illumination for the instrument cluster lights up whenever you
switch on the ignition with the
vehic le headlights off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and will go out completely when the outside light is
very low. This feature is meant to remind you to switch on the head­
lights when outside light conditions become poor. •
Engine coolant temperature gauge
The engine coolant gauge=> fig. 2 G) only works when the ignition
is on. To prevent damage to your engine, please note the following
important points:
Engine cold
As long as th e needle remains at or close to the bottom of the
gauge, the engine still has not reached its operating temperature .
Avoid high engine speeds , heavy engine loads and heavy throttle
applications.
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 rise up . This is no need to worry as long as the
_f_ warning light
in the instrument cluster does not illuminate . .,

Instruments and warning/indicator lights
Warning light in the instrument cluster -t
When the _L warning light in the instrument cluster 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 33.
If the needle is well in the upper area of the gauge, the coolant
temperature is too high.
Stop the vehicle, switch the engine off and
allow the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Always observe the warning in ~ page 324, "Engine compart­
ment", before opening the hood and checking the engine coolant
level.
• 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 cooling effect of the radiator. At high outside tempera­
tures or high engine load, the engine could overheat.
• The front spoiler 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 authorized Audi dealer for assistance. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes).
The tachometer 0 ~ page 13, fig. 2 is the left of the two large clock ­
type displays. The
engine turns at a speed
1,000 times the single digit in the
display, e.g. if the needle is pointing at the "2" the engine is turning
at 2,000 RPM.
If engine RPM drops below 1,500, you should downshift to the next
lower gear. The red area at the end of the scale indicates maximum
permissible engine RPM after the break -in period. Before reaching
this area, move the selector lever to position "D (Drive)" or ease your
foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range. If it
does, then only for a
very short period of time. You could damage
your engine by driving at high RPM .
'£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
Digital clock with date display
Date and time of day can be set in the MM/.

Warm and cold
Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 72 °F (+22 °C).
- Press the [AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal
needs .
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically
regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode:::::, page 126
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . Th is
is normal and does not indicate a leak.
Controls and equip ­
ment
If the outside temperature is low, the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle. The air is also filtered in air recir­
culation mode.
The air pollutants filter must be changed at the intervals specified in your Warranty
& Maintenance booklet, so that the air conditioner
can properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your
Audi Warranty
& Maintenance booklet . If in doubt, ask your autho ­
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored. _.,
