mation System menu, and select and confirm
Wh eel ch ange. You
must do this each time to change a tire . The procedure can take up
to 20 minutes driving time. During this time, the sensors are read ­
justing to the new wheel/tire combination, and the new pressures are stored.
During the learning phase, the tire pressure monitoring system is
not available. •

Syst em m alfu nct ion
If the 'warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additional ly the --, -=> fig. 35 symbol appears in the display, the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears a t the end of the learning phase, the
system cannot recognize the wheels installed on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed.
• A wheel sensor or other component may have failed. •
The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system.
• A tire was changed but the=>
page 45, "Changing a wheel"
procedure was not activated =>
page 45.
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro ­
m ised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be ava ilable
because of a radio malfunction.
• Transmi tters with the same frequency, such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Try to find the cause of the interference, and then perform the
=>
page 45 , "Changing a wheel" procedure one more time . If this not
e liminate the prob lem, contact your authorized Audi dealer for
assistance .
• Do not use commercial ly availab le tire sealants . Otherwise, the
e lec trical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system wi ll have to be rep laced by a qua lified workshop .•

Cleaning and protection -
----------------
•
High temperatures, as from exposure to intense sunlight, intensify
the corrosive effect particularly when humidity is high as well.
Under certain circumstances,
weekly washing may be necessary.
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and the information
~ page 230. •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash. However, the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material , etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
The power top does not require specia l precautions before passing
through a car wash.
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adversely affect the power
top and even damage the fabric over a period of time.
The power top does not have to be washed every time you use a car
wash . The power top can be spared if the car wash facility is
equipped with manually adjustable roof brushes or rollers.
Before going through a car wash, be sure to take the usual precau­
tions such as closing the windows and power top. The factory-fitted antennas for the radio, car phone and navigation system* are all
located inside the vehicle interior.
If you have installed additional accessories on the vehicle
-such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
& WARNING
Always read and heed all WARNINGS and the information
~ page 230. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
- Before you start washing, make sure you have read and
understood the WARNINGS=>
& in "General informa­
tion" on page 230.
- First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door sills and other
regions exposed to road dirt. In this way, you wil l not scratch the
paint with coarse particles imbedded in the sponge the next time
you wash the car. ..,.

[ i] Tips
• Whenever replacing a fuse, always consult the sticker on the
inside of the fuse panel cover. It contains the most up-to-date infor­
mation regarding the fuse arrangement . If in doubt, ask your autho­
rized Audi Service advisor.
• Some of the equipment items listed are optional or only avail­
able on certain model configurations. •
Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must first be removed before
you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent breakage of parts and long
term damage from water that can enter housings that have not
been properly resealed.
For your safety, we recommend that you have your authorized Audi
dealer replace any bulbs for you, since your dealer has the proper
tools, the correct bulbs and the expertise.
Gas discharge lamps (xenon lights)*:
Due to the high electrical voltage, have the bulbs replaced by a qual­
ified technician. Headlights with xenon light can be identified by the
high voltage sticker.
& WARNING
Contact with high-voltage components of the electrical system
and improper replacement of gas discharge (Xenon) headlight
bulbs can cause serious personal injury and death.
• Xenon bulbs are pressurized and can explode when being
changed.
• Changing Xenon lamps requires the special training, instruc­
tions and equipment.
• Only an authorized Audi dealer or other qualified workshop
should change the bulbs in gas discharge lamps.
& WARNING
There are parts with sharp edges on the openings and on the bulb holders that can cause serious cuts .
