You can centrally lock and unlock your vehicle
and start the engine with the master key with
remote control. A mechanical key is integrat­
ed in the remote control key
r:::;, page 31 .
@ Eme rgency ke y
The emergency key is not intended for con­
stant use.
It should only be used in an emer­
gency. Keep it in a safe place and do not carry it on your key ring .
Key replac em ent
If you lose a key, contact your authorized Audi
dealer immediately to have the
lost key disa­
bled. Be sure to bring all your keys with you.
P er sonal c omfo rt se ttin gs
If two peop le use one vehicle, it is recom­
mended that each person always uses "their
own" master key . When the ignition is switch­
ed off or when the vehicle is locked, personal
convenience settings for the follow ing sys­
tems are stored and ass igned to the remote
maste r key.

A WARNING ,~
- Do not leave your vehicle unattended . Al­
ways take your ign it ion key with you and
lo ck your vehicle. Ent ry by unauthorized
persons could endanger yo u or result in
theft or damage the vehicle .
- Do not leave ch ildren unatte nded in the
veh icle, especially with access to vehicle
keys . Unguarded access to the keys pro ­
vides children the opportunity to start the engine and/or activate vehicle sys­
tems such as the power windows, etc.
Unsupervised operation of any vehicle
system by children can result in serious
in J ur y.
(D Tips
- The operat ion of t he remote control key
can be temporarily disrupted by interfer­
ence from transm itters in the vic inity of
the vehicle working in the same frequen­
cy rang e (e .g. a cell phone, radio equ ip­
ment).

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior .
It is the most effective when the windows and
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: the blower set ­
ting and air distribution are stored automati­
cally and ass igned to the remote control key
that you are using.
Four-zone automatic climate control: The cli­
mate contro l settings are automatica lly stor­
ed and assigned to the remote control key
that is in use .

A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear
window. When plac ing items of cloth ing
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 vehi­
des -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 vehi­
cles that were equipped with them at the
factory. The vehicle must have a chassis designed for run flat tires . Incorrect use
of run flat tires can lead to vehicle dam­
age or accidents. Check with an author­
ized 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. Mix­
ing tire types is not permitted.
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
Tires and wheels 249
- 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
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c:> page 246,
fig. 182.
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 1S0 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. .,.. •
