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 35. _,.

[ i J Tips
• If the warning/indicator light BRAKE (USA models)/ «D> (Canada
mode ls) in the instrument cluster flashes, the re is a brake system
malfunction. By press ing the [ CHECK] button, you can bring up a
dr iver message which explains the ma lfunct ion in more deta il. Please
note =>
page 34 .
• Speed wa rnings threshold 1 9 (USA mode ls)/ 0 (Canada models)
and threshold 2
8 , (USA mode ls)/ 8, (Canada models) are also shown
as red symbols . T he warning is a lways shown as a sma ll symbol in the
upper area of the display=>
page 31. •
Alternator malfunction 0
If the D symbol in the instrument panel display flashes, then there
is a malfunction in the a lternato r or the veh icle electronics. A warning
to the driver will appear, too. The driver warning goes out after about
5 seconds, but it can be b ro ught up at any time by pressing the
I CHECK] button again .
Usua lly, you can still drive to the next dealership. Turn off a ll but the
most necessary electr ica l consumers, since these drain the veh icle's
battery.
0 Note
If the _ f_ warning symbol (coolant system malfunction) also lights up
on the instrument panel dur ing the trip=>
page 35, then you have to
stop immediately and turn off the engine. The coolant pump is not
working anymore -danger of damage to the engine! •
Brake system malfunction
A malfunction in the brake system must be repaired as
soon as possible.
If the warning /indicator light BRAKE (USA models)/ (CD)
(Canada models) in the instrument cluster flashes, there is a
brake system malfunction. By pressing the
[CHECK] button,
you can bring up a driver message which explains the malfunction in more detail.
Stop v ehicle and check brake fluid level

light come on together, the rear wheels could lock up first under
hard braking. Rear wheel lock-up can cause loss of vehicle control
and an accident. Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light((]:» and the ABS
warning light come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.

A malfunction in the engine cooling system must be
repaired as soon as possible.
When the -L 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 :::>

-Add coolant if necessary=> page 310.
-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 O warning symbol (alternator malfunction) also lights up on
the instrument panel:::::,
page 34, 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

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 114
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. _.,

page 182, "Towing a trailer". •
Driving instructior,s
Driving with a trailer always requires e xtra care and
consideration.
To obtain the best possib le handling of ve hicle a nd trailer ,
please note the following :
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especia lly careful when pass ing other vehicles .
- Observe speed limi ts.
- Do not drive at the maximum pe rmissible speed.
Controls and equip­
ment Safety first Vehicle operation
- Always apply brakes early.
- Mo
nitor the temperature gauge.
Weight distri but ion
T owing a loaded trailer with an empty car results in a highly unstable
distribution of we ight . If t his cannot be avoided , drive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that the
tow veh icle shou ld be loaded to the extent poss ible and permissib le,
wh ile keeping the tra ile r as lig ht as poss ible unde r the ci rc u mstances.
Whe never possible, transfer some cargo to the luggage compart ­
me nt o f the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
The higher the speed, the more d ifficult it becomes for the driver to
control the r ig . Do not dr ive at the maxim um permiss ible speed .
Reduce your speed eve n more if load, weather or w ind conditions are
unfavorable -particular ly when going downhill.
Reduce vehicle speed
immed iately if the tra ile r shows the slightest
sign of swaying.
Do not tr y to stop the s wayi ng by a ccele rating .
Observe speed lim its. In some areas, speeds for veh icles towing
trailers are lowe r than for regular veh icles .
Always apply brakes early. When driving downhi ll, shift into a lower
gear to use the engine brak ing effect to slow t he ve hicle . Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperatur e
The coo lant temperature gauge=> page 10 must be observed care­
fu lly. If the needle moves close to the upper end of the sca le, reduce
speed immediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the instrument clus ter
starts flash ing
- F- , pull off the road, stop and let the engine idle for
about two m inutes to prevent hea t buil d-up.
