Fig. 80 Moun ting points fo r the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:

u. 00 .-< N l'­ N .-< 0 N > 00
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roof rack, make sure that it
is mounted on ly at the designated points on
the roof ¢
fig. 79 or ¢ fig. 80.
-Note the permitted axle load, permitted tota l
weight, and permitted roof load of your vehicle
¢
page 382 . The roof load is the tota l of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must also note the permitted load of the carr ier sys­
tem being used .
A WARNING
-Follow the installat io n instructions provided
with the roof rack system. If you do not se­
cur e the roof ra ck sys tem and objec ts on the
roof correctly, they co uld come loose from
the vehi cle and cause an accident.
- T he ris k of an a cc ident i ncreases when using
a roof rack system, because it changes the
driving characteristics by shifting the center
of gravity and/or the increasing the s urface
area exposed to wind. You may need to
adapt your driv ing style and speed to the
current conditions.
@ Note
- If you use other roof luggage rac k systems
or do not insta ll the racks as intended, any
damage to the ve hicle is not cove red by the
warranty. Carefully follow the assembly and i nsta llation instruct ions included with the
r oof rack car rier system .
- Make sure t hat the luggage compartment

Warm and cold
Warm and cold Climate control system
Description
The climate control system circulates , warms or
coo ls, and removes humid ity from the air in the
veh icle interior . It is the most effective when the
windows and panorama g lass roof* or power top*
are closed. If there is a build-up of heat inside
the vehicle, ventilation can help to speed up the
coo ling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and po llen from the air.
Key recognition
Various sett ings are stored and ass igned to the
remote control key being used.
These settings are different when the power top* is open or closed .
Presetting
Several functions can be preset in the Infotain­
ment system.
Select in the Infotainment system:
IMENU ! but­
ton
> Vehicle > left control button > Air condi­
tioning
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar with the correct use and
function of the climate control system as
quickly as poss ible, espec ia lly with the de­
frosting and defogging functions.
- When the temperature is below freezing, only use the windsh ield washer system after
68
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visib ili­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Aud i dealer or authorized
Audi Serv ice Facility.
- Repa irs to the Aud i climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
o r authorized Aud i Serv ice Facility .
@ For the sake of the environment
-To save fuel, turn off the climate control
system cooling mode by press ing the A/C
button. This w ill also reduce emissions . The
climate control system is off when the LED
in the button turns off.
- In vehicl es w ith the efficie ncy prog ram*,
yo u can find other consumpt ion information
and more economy tips ¢ page 19.
© Tips
- To prevent int erference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
drip and form a pudd le of water under the
vehicle . This is normal and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.
