Rear air vents
The rear air vents are located in the center console.
- Rotate the thumbwheel to open and close the vents.
- To ad just the direction of the airflow from the outlet,
move the tab in the center of the outlet in the desired
direction. The direction of the air delivered from the
vents can be adjusted horizontally and vertically.
The air vents are actuated either automatically or manually d e pending on the op erating mode selec ted . H eated or unh eated
fresh air, or cooled air flows from the vents.
i he ai r ven ts to heat the rear footwell are located under the front
seats.
[ i J Tips
If the climate control is operating in cooling mode, air flows prima ­
rily from the vents in the center console. To achieve adequate
cooling, you should never close these v ents completely. •

Economical use of the climate control system
Economical use of the climate control system helps save
fuel.
When the climate control system is working in cooling mode, engine performance is reduced and fuel consump- tion is affected. To keep the time
the climate control system
is on as short as possible, you should do the following:
- To save fuel, turn off cooling mode by pressing the
[AC )
button (ind icator light goes out).
- In addition, if you open the window or the
panorama/tilting sunroof* while driving, turn off cooling
mode by pressing the
[AC) button (indicator light goes
out).
- If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows .
c£> For the sake of the environment
When you save fuel, you reduce emissions from the vehicle. •

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 °Cl.
- Press the [AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . Change th is s etting, as des ired, to meet your personal
needs .
~

The climate controls are a combination of heating, ventilation and
cooling sys tems, which automa tica lly reduce humidity and cool the
air inside your vehic le .
The climate contro l automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatica lly adjusted. The
system also takes into account strong sunsh ine so that manual
adjustment is not necessary . So in almost all cases,
a ut oma tic mode
offers the best co nditions for the comfort of the occupants at all
times of the year~
page 99.
Please note the following :
Turn on the air conditioner to reduce hum idity in the veh ic le. This
a lso prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
c onden sation from the evaporator may drip under the vehicle . T his
is normal and does no t indicate a leak.
If the outside temperature is low, the fan norma lly on ly switches to
a higher speed once the engine coo lant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from a standstill using fu ll 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.
Du st and poll en filte r
The dust and pollen filter (a combined particle filter and activated
cha rcoal fi lter) reduces or prevents outside air pol lut ion (dust, or
pollen) from entering the vehic le .
The dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can prop­
erly work .
I f you drive your vehicle in an area with a high degree of a ir pollu­
tion, the filter may need to be changed more frequent ly than speci-

Energ y mana gement
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts o f
energy are temporarily cut back or switched off~
page 241.
Hea tin g systems in particu lar req uire a great dea l of energy. I f you
notice, for examp le, that the rear window heater is not heating, then
it has been temp orarily cut back or switched off by
energy manage ­
ment .
These systems are available again as soon as the energy
balance has bee n res tored .
& WARNING
Redu ced vi sibilit y is dangerou s and c an cau se a ccidents .
• For safe driving it is very important th at all windows be free of
ice , snow and conden sation .
• Completely familiari ze yourself with the proper use and fun c­
tion of the heating and ventilation sy stem and e speci ally how to
defog and defrost the windo ws.
• Never use the wind shield wiper /w asher sy stem in freezing

• Repairs to the Audi ai r conditioner require special technical
know ledge and special tools. Contact an authorized Audi dea ler for
assistance.
[ i ) Tips
• To avoid adversely affecting hea ting and cooling performance
and to preven t condensation on the windows, the air intake in front
of the windshield must be free of ice , snow and leaves.
• The air flowing out of the ven ts and throughout the vehicle 's
entire interior is d ischarged at the rear of the vehicle . Make sure tha t
the outle t slots are not cover ed by clothing, etc .
• Climate control works mos t effectively if the windows and the
panoramic s liding /ti lting sunroof * are closed. Howeve r, if the in te ­
rior of a parked vehicle is extremely hot from the sun, briefly
opening the windows can speed up the cooling process. •

defogger is activated for 10 to 20 minutes, depending on outside
temperature. When a vehicle is parked for a short time , the rear
window defogger does not need to be manually activated again.

As soon as the rear window is clear, you should switch the rear
window defogger off. The reduced power consumption has a bene­

Automatic recirculation
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic recirculati on ON to
prevent polluted outside air from entering the vehicle interior. .,_

Trailer load d is trib ut ion
Be sure the load in the trailer is held securely in place to prevent it
from shifting forward, backward or sideways.
Ne ver allo w a passen ger to rid e i n a tr ailer => & in "Driving instruc ­
tions" on
page 249.
En gin e c ool ing syst em
Towing a trailer makes the engine work harder. It is important that
the cooling system 's performance is up to the additiona l load. Make
sure that the cooling system has enough flu id.
Ti re press ure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the labe l located either on the
driver's side B-pillar (visible when the door is open} or inside the fuel
filler flap . Inflate trailer tires to trai ler and tire manufacturers' spec ­
ifications.
Ligh ts
The headlight settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trailer lights
are working properly .
Safe ty c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from dropping in case of separation from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
Do not tow a loaded trailer when your car itself is not
loaded .
- Be especia lly careful when passing other vehicles .
Observe speed l imits .
Do not drive at the maximum permissible speed.
Always apply brakes early.
Monitor the temperature gauge.
W eight distrib utio n
Towing a loaded trailer with an empty car results in a h ighly
unstable distribution of weight . If this 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
t he tow vehicle should be loaded to the extent possible and permis ­
sible, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations.
S pee d
The higher the speed, the more difficu lt it becomes for the d river to
control the rig. Do not drive at the maximum permissible speed.
Reduce your speed even more if load, weather or wind conditions
are unfavorable -particularly when going downhill .
Reduce vehicle speed
i mmed iatel y if the trailer shows the slightest
sign of swaying .
Do not try to st op the swa ying b y accelerating.
