78 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof* are closed . If the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pol lutant filter removes pollutants such
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
I f you drive your vehicle in an a rea with high
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The climate control settings are a utomat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents. -
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and funct ion of the heat ing
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ sh ie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
deri nflated.
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory . The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
(D Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth-
Tires and wheels 259
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged .
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
-Tread wear
- Tract ion AA A B C
- Temperature AB C
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c;, page 256,
fig. 212.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al 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 controlled conditions on a specified
government test course.
For example, a tire graded ISO would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depart significantly from the
norm due to variations in driving habits, serv­
ice practices and differences in road character-
istics and climate.
