Warm and cold
Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature.
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y re cognition
A pp lies to: ve hicles w ith de luxe au toma tic clima te co ntrol
The blower sett ing and air distribution are stored
automatically and ass igned to the remote control
key that you are using.
A pp lies to: ve hicles w ith 4 -zo ne del uxe automatic c limate
co ntrol
The climate control set tings are automatically
stored and assigned to the remote control key
that is in use.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with
the correct use and function of the climate contro l system, especially with the defrost­
ing and defogg ing function.
58
- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­ mate control system . The washer fluid could
freeze on the w indsh ield and impair v isib il i­
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 dea ler or authorized
Audi Serv ice Facility.
- Repa irs to t he Aud i climate control system
require special techn ical know ledge and
special tools. See an aut ho rized Aud i dea le r
or authorized Aud i Serv ice Fac ility .
@) For the sake of the environment
To save fue l, turn off cooling mode by press­
i ng the
IA/Cl button. This will a lso reduce
emissions.
(D Tips
- T o prevent i nterference with t he heat ing
and cooli ng outpu t and to p revent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- C ondensation from the coo ling system can
drip and form a pudd le o f water under the
vehicle . This is norma l 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.

To reduce the risk of lime sca le deposits on the
spray nozzles, use clean water with low amounts
of calc ium . A lways add window cleaner to the wa­
ter. When the outs ide temperatures are cold, an
anti -freezing agent should be added to the water
so that it does not freeze .
@ Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
cond itions in the respective climate. A con­
ce ntration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
Checking and Filling
- Do not use a glass cleaner that contains
paint so lvents, because t his could damage
the paint.
Service interval display
The service interval display detects when your ve ­
hicle is due for service .
The service interval display works in two stages:
-Inspection or oil change reminder : afte r a cer -
tain distance driven, a message appears in the
instrument cluster display each time the igni­
tion is switched on or off. The remaining dis­
tance or time is disp layed briefly.
- Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same t ime, the mes­
sage
Inspection due! or Oil change due! or Oil
change and inspection due!
appears briefly af ­
ter switching the ignition on/off .
Checking service intervals
You can check the remaining distance or time un ­
til the next oil change or next inspection in the
Car menu. To do t his, select: the !CAR !function
button
> (Car)* Systems control button > Service
& control > Service intervals .
Resetting the indicator
An authorized Audi dea ler or a uthorized Audi
Service Facility w ill reset the service interval dis­
play after performing service.
If you have ch anged the oi l yourse lf, you must re ­

Wheels
- Traction AA A B C
- T emperature ABC
Quality grades can be found where appl icable on
the tire side wall between tread shoulder and
maximum section width
~ page 206, fig. 187.
For example: Tread wear 200, Traction AA, Tem ­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under contro lled conditions on a specified gov ­
ernment test course.
F or examp le, a tire graded
150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded
100.
The relative performance of tires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
abi lity to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
~ .&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to d iss ipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excess ive temperature can lead to sudden
tire
fa ilure ~.&. .
The grade C corresponds to a level of perform ­
ance which a ll passenger car tires must meet un-
222
der the Federal Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire tha t is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are
proper ly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your veh icle has
t ir es of a diffe rent size t han the size ind icated on
the vehicl e placard or tire infl ation press ure la ­
bel, you sho uld determine the proper tire infla­
tion pressure for those tires).
As an added safety featu re, you r vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell ­
ta le when one or more of your tires is significant­
l y under-inflated. According ly, w hen the low tire
pressure telltale illuminates, you should stop and
check your t ires as soon as possible, and inflate
them to the proper pressure. Dr iving on a
