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 need le remains at the le ft end of the gauge, the engine
st ill has not re ached its operating tem perature. Avoid high eng ine
speeds, heavy engine loads and heavy throttle applicat ions.
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
go furthe r to the right. This is no need to wo rry as long as the _JL
wa rning light in t he instrument cluster does not illuminate .
Warning light in the instrument cluster -t
When the _ L warning light starts to flash, this ca n mean one of two
t hings: e ither the cool ant
temperature is too h igh, or the coolant
level is too low=> page 29. _,.

& WARNING
• Always observe the warnings in ::::> page 281, "Engine compart­
ment", before opening the hood and checking the brake fluid.
• Driving with low brake fluid is a safety hazard. Stop the car and
get professional assistance.
• USA models: If the BRAKE warning light, the ~ warning light
and the 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 immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden, hard brake applica­
tions.
• Canada models: If the brake warning light(())), the r-warning

Warm and cold
Climate controls
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 75
°F (+23 °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 106
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 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.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e coolant temperature gauge~ page 10 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
_f_ , pull off the road, stop and let the engine idle for
about two m inutes to prevent heat build-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi.•
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop. To compensate for the
trailer, you will need a larger than normal turning radius .
When passing, remember that you cannot accelerate as fast as you normally would because of the added load . Make sure you have
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 361. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
- Apply the foot brake.
- Have someone p lace chocks under both the vehicle and the
trailer wheels . ._
