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 follow ing settings:
- Set the temperature to 75 °F (+23 °C).
- Press the !AUTO
I 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 117
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. 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
charcoal 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 autho­
rized 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

Safety tips
The side ass is t de tect io n m ay be limi ted whe n driving a round
narrow s treet corners, on hilly streets, and under poor w eat he r
condit ions.
It is possibl e that the r ad ar sen so rs may also d etect oth er obje cts,
such as high or staggered guardrails.
Sid e assis t does no t measure ac tual lane w idth. The sys te m
assu mes a fixed lane widt h. D etect ion in the left and right lanes is
based on thi s assumed lane width . When driving on na rrow roads or
when driv ing to th e left or right of the c enter o f a trav el lane, it is
possible that veh ic les wi ll be detected that are
not in the lane next
to the l ane y ou are us ing .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and serious personal injury:
& WARNING (continued)
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
change lanes .
• Side assist cannot detect all vehicles under all conditions ­
danger of accident !
• Side assist cannot detect vehicles
in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The radar sensor's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray. This can result in side assist not
adequately detecting vehicles or, in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h) .
• Side assist signal does not work around tight corners (turning
radius less than 328 feet , or 100
ml.
• Side assist is no replacement for the driver's full attention. The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
0 Note
To ensure that s ide assist is not adversely affected , you s hou ld not
block the area on the rea r bumper where the radar sensors a re

components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in you r Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• For safety reasons in severe accidents , the alternator and
starter are separated from the vehicle battery with a pyrotechnic
c ircuit interrupter .
- Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit interrupter is scrapped , all appli ­
cable safety precautions must be followed .
