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 needle rema ins at or close to the bottom of the gauge,
t he engine s till has not rea ched its operat ing tem perature. Avo id high
eng ine speeds, heavy eng ine loads and heavy t hrottle app lications.
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
r ise up. This is no need to worry as long as the
_t_ warning light in th e
instr ument cluster does not illuminate.
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: e ithe r th e coolan t
temperature is
too high, or the coolant
level is too low=> page 30. _,.

If the needle is well in the upper area of the gauge, the coolant
tempe rat ure 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
• Alway s observe th e warning in=> page 286 , "Engine comp art ­
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
s ee engin e 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 additiona l lights or accessories in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­
t ur es o r high engine load, the engine could overheat.
• The front spo iler has bee n des igned to prope rly d istribute the
coo ling air when the vehicle is moving.
If the spoiler is damaged, this
cou ld reduce the coo ling effect and the eng ine could then overheat .
Ask your author ized A udi dealer for assistance .•
Tachometer (engine rev counter)
The tachometer indicat es th e engine RPM (revolutions
per minutes).

Engine cooling system malfunction -L
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the .J_ symbol in the display blinks, then either the
engine coolant
temperature is too high, or the coolant level
is too low. An additional driver message can also be displayed
by pressing the
[CHECK) button:
Switch off engine and check coolant level
-Pull off the road.
- Stop the vehicle.
- Turn off the engine .
- Check coolant level~
page 305.
-Add coolant if necessary~ page 306.
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be the
cause of the malfunction.
If the
D wa rning symbol (alternato r malfunction) also lights up on
the instrument panel~
page 29, then the fan belt may be damaged .
& 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 68, "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 of
the engine and allow it to cool. Follow the warning stickers
~ page 286, "Engine compartment".

Do not continue driving if the _f_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine .•

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] 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 112
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 . This is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
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 char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle. The air is also filtered in air recirculation
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 authorized
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. _.,

adjustment is between 1 and 6.
The heater for the front seats can be turned on when the weight of
the particular seat's occupant is detected. However, the front seats
can be pre -heated for about 10 minutes using the activated seat
heater. After this time has e lapsed, the seat heater automatic ally
turns off if it does not detect an occupant's weight for the particular
seat.
0 Note
To avoid damage to the heating elements in the seats, do not kneel
on the seats or p lace heavy loads on a small area of the seat.
[I] Tips
Please note that the weight of objects placed on the seat wi ll also be
detected. This weight may be enough to cause the seat heater to turn
on. •

a need for concern .
If the engine does not start immediately, stop trying after 10 seconds
and then try to rest art the engi ne about 30 seco nds la ter.
Glow plug system*
Diesel engines are eq uipped with a glow p lug system whose

& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon mono xide, a color­
le ss 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 person al injury or
theft.

& 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
i s running . With the ignition turned off, you have to apply more
force when steering or b raking. Since you cannot stee r and stop
normally, this can lead to accidents and serious injuries.
• The radi ator fan can continue to run for up to 10 minute s 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. ..,,
