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.

Automatic climate cont rol system
The automat ic climate control system automati­

defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a certain temper­
ature.
AUTO

cooling mod e
The cooling mode on ly functions with the blower
turned on. You can turn the cooling system on or
off by pressing the A/C button. The air is not
cooled and humidity is not removed when cooling
mode is switched off. This can cause fog on the
windows . The cooling mode sw itches off auto­
matically when there are cold outside tempera­

The temperature for the driver's and front pas­
senger's s ide can be adjusted separately with the
dials

Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1 ,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Warming up/cooling down
Applies to: RS models
By warming up/cooling down the engine carefu l­
ly, you can help reduce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
72
The tires only reach t heir full road ho ld ing capa ­
bility once they have warmed up under load.
Yo ur vehicle also has an afte r-run cooli ng fea ­
tu re . Howeve r, cooling down is st ill import ant.
The eng ine and t he brakes as we ll as the exhaust
system and the transmission become very hot
when driving in a sporty style. Before you shut
the veh icle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
ce leration .
Driving through water on roads
Note the following to reduce the risk of veh icle
damage when dr iving throug h wate r, fo r example
o n flooded roads:
-The water must not be any higher than the bot ­
tom of the vehicle body .
-Do not drive faster than walk ing speed .
A WARNING
After driving thro ugh water or m ud, the effec­
tiveness of t he b rakes may be reduced due to
mo istu re o n the bra ke rotors and brake pads.
A few ca reful br ake app lica tions sho uld d ry
off the bra kes and restore the fu ll b raking ef ­
fect.
@ Note
-Vehicle components such as the e ng ine,
t ra nsmiss ion, sus pens io n or elect rical sys ­
tem can be severely damaged by d riving
throug h water.

(j) Tips
-De ter mine the dep th before dr iving throug h

-Do not stop the vehi cle, d rive in reverse or
switch t he e ngine off whe n driving through
water .
-Keep in mind that o ncom ing vehicles may

~ Brake the vehicle to a stop . The engine stops
shortly before the vehicle comes to a stop or if
the ve hicle is stationary

Add ition al informa tion
The engine stops in the "P", "N" and "D" selector
lever positions .
If you select the "R" selector lever position during
a Stop phase, the engine will start again.
Shift to "P" quickly to prevent the engine from
starting unintentiona lly when shifting t hrough

You can determ ine for you rself if the engine will
stop or not by reducing or increasing the amount
of force you use to press the brake pedal. For ex­
ample, if you only light ly press on the brake ped­
al in stop-and-go traff ic or when turning, the en­
g ine will not switch off when the vehicle is sta­
tionary . As soon as you press the brake down
harder, the eng ine will switch off .

A WARNING
- Do not press the acce lerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the eng ine is running . Oth­
erwise, the vehicle will start to move imme­
d iate ly and this could resul t in an accident.
- Emerge ncy brak ing should only be used in

has fa iled or the bra ke peda l is obstr ucted.
D ur ing eme rgency bra king, you r vehicle w ill
brake s imilar to he avy braking. ESC and the
associated components (ABS, AS R, EDL)
cannot overcome the laws of physics.
Around curves and when road or weather
conditions a re bad, a full brake applicat ion
can cause the veh icle to skid or the rear end
to swerve, wh ich increases the risk of an ac­
cide nt.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
pa rk the veh icle on leve l ground and secure
it by p lac ing the sele cto r leve r in the P pos i­
tion. See an au thor ized A udi dealer or au ­
thor ized A udi Se rvi ce Fa cility for assis tan ce.
- I f you leave the vehi cle, sw itch the ignition
off and take the veh icle key wi th yo u. Thi s
app lies pa rticular ly when children remain in
the vehicle. Otherwise, chi ld ren co uld start
the engine, release the parking brake or op ­
erate e lectr ica l equipment s uch as power
w indows, wh ich increases the r isk of an acci­
dent.
- No one, especially c hildren, should rema in
in the vehicle when it is locked. Locked
doors make it more difficu lt for emergency
workers to get into the vehicle, which puts
lives at ris k.
(D Tips
When stopp ing at a traff ic signa l or stopp ing
i n city traffic, you can set the park ing brake
manually . The veh icle does not have to be
