service station can interpret the code and per­
form the necessary repair.
Electronic speed limiter
Your vehicle may be factory equipped with
tires that are rated for a maximum speed of 130 mph (210 km/h) . Thi s is less than the
maximum speed of your vehicle . To reduce the
ri sk of sudden tire failure and loss of control if
the vehicle is ope rated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information ¢
page 246.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
II will i lluminate. If this
occurs, contact the nearest author ized Audi
dea ler for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions . Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.

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 .
