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 .

Deluxe automatic climate control

Applies to vehicle s: with D elu xe a utoma tic cl ima te co ntrol p lus
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

You can adjust the air distribution so that air flows from specif ic
vents. In position
:0 air flows only to the windows, in position :J, it
flows to the driver or passenger , and in position

dis tribution as needed .
To regulate a ir distribution automat ically, switch to [AUTO] .

Rear window defogger [CiWj
The rear window defogger clears the rear window of
condensation.
- Press the ICiW ] button to turn the rear window defogger on
and off.
The rear window defogger works only when the engine is running.
The indicator light in the button illuminates when the rear window
defogger is on. The
rear window defogger is switched off automatically after 10 to
20 minutes, depending on the outside temperature.
The rear window defogger can be turned on permanently by
pressing the
[Cial] button for more than two seconds. This remains
stored until the ignition is switched off . A rear window defogger that
was switched on also remains stored for 15 m inutes after the igni ­
tion is switched off.
If the engine is restarted within these 15 minutes , the rear window
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.
~ For the sake of the environment
As soon as the rear window is clear, you should switch the rear
window defogger off. The reduced power consumption has a bene­
ficial ef fect on fuel consumption .•

safety functions.
When starting from rest

& WARNING
If a gear or a drive range (automatic transmission) is engaged with
the vehicle stationary and the engine running, you must in no
instance accelerate or release the clutch carelessly . Otherwise the
vehicle will start to move immediately -risk of an accident.
0 Note
If the symbol (CD) in the display or the indicator light BRAKE (USA
models)/ {(i)) (Canada models) in the instrument cluster flashes, there
is a malfunction in the brake system. By pressing the
[SET] button,
you can bring up a driver message which explains the malfunction in more detail. If the driver message
Parking brake! appears, there
is an operating malfunction in the parking brake which you should
have repaired immediately by an authorized Audi dealer or other
qualified workshop ~
page 29.
[ i] Tips
• You can apply the parking brake at any time -even with the igni ­
tion turned off. The ignition must be turned on in order to release
the parking brake.
• Occasional noises when the parking brake is applied and
released are normal and are not a cause for concern.
• When the vehicle is parked, the parking brake goes through a
self -test cycle at regular intervals. Any associated noises are
normal. •
Parking
Various rules apply to prevent the parked vehicle from
rolling away accidentally.
Parking
- Stop the vehicle with the foot brake.
Controls and equip ­
ment
- Pull the switch to apply the parking brake.
- Automatic transmission*: Move the selector lever to
P.
- Turn the engine off=:,& .
- Manual transmission: Shift into 1st gear.
In addition on inclines and grades
-Turn the steering wheel so that your vehicle will roll
against the curb in case it should start to move.
& WARNING
• When you leave your vehicle -even if only briefly -always
remove the ignition key. This applies particularly when children
remain in the vehicle. Otherwise the children could start the
engine, release the parking brake or operate electrical equipment
(e.g. power windows). There is the risk of an accident.
• When the vehicle is locked, no one -particularly not children
should remain in the vehicle. Locked doors make it more difficult
for emergency workers to get into the vehicle -putting lives at
risk. •
Starting from rest
The starting assist function ensures that the parking
brake is released automatically upon starting.
Stopping and applying parking brake
-Pull the switch to apply the parking brake.
Starting and automatically releasing the parking
brake
-When you start to drive as usual, the parking brake is
automat ically released and your vehicle begins to move . .,..
