& WARNING
Always read and heed all WARNINGS and the information
~ page 230. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
aluminum surfaces. Chrome care products and alkaline cleaners
will attack aluminum surfaces and can damage them over time.
& WARNING
Always read and heed all WARNINGS and the information
~ page 230 . •
Touch-up paint
Minor paint damages should be touched up immediately.
-Use either a touch-up paint stick or spray paint to cover
minor scratches and nicks.
Your Audi dealer has touch-up paint for minor scratches and stone
chips. Scratches should be touched up soon after they occur to
prevent corrosion.
If a spot starts to rust, however, a simple touch-up job will not be
enough. The affected surface must be smoothed with sand paper
and covered with an anti-rust primer before the painted finish can
be restored.
The number for the original vehicle paint can be found on the
vehicle identification label~

Windows
Clear vision to all sides.
Clean all windows regularly to remove road film and
carwash wax buildup.
Remove snow from windows using a brush.
- Use a plastic ice scraper to remove ice from windows and
mirrors.
- Remove other residue on the windows with a spray-on
glass cleaner.
Wipe the windows dry with a clean piece of cloth or kitchen paper towel.
The best way to remove snow from windows and mirrors is to use a brush. Use a non -abrasive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can interfere with the function of the windshield wiper blades (chatter!.
Oil, grease or silicone residue can be removed with
glass cleaner or
silicone remover . However, wax residue requires the use of a
specially formulated solvent. Please contact your Audi dealer for
advice on safe products for wax removal.
Windows should also be cleaned on the inside at regular intervals. _,.

Have the battery checked when you take your vehicle in for service .
You are well advised to replace a battery that is older than 5 years.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected . Th ese functions have
to be relearned after the battery terminals are connected again. To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs .
Vehicles not driven for long periods
If you are going to let your vehicle stand for a long time and not
drive it, you should remember there are electrical components
which are still functioning and they will draw energy from the
battery and drain it, for example, the engine immobilizer. To prevent
this, you can either charge the battery occasionally to keep it in
good working condition or you can disconnect the negative cable
on the battery.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when traveling only short distances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=>
page 265 . A we ll charged battery wil l not only prevent starting
problems when the weather is cold, but will also last longer.
Replacing battery
The new battery must have the same capacity, voltage (12 volts),
amperage, construction and plug sea ling, as the origina l battery.
Specifications are listed on the battery housing. Batteries specially
developed by Audi fulfill the maintenance, output, and safety
requirements. When installing the battery, make sure the ignition and all electrical
consumers are switched off=>
0.
We recommend that you use maintenance -free or cyc le-resis­
tant/leak-proof
batteries according to the standards TL 825 06 (from
December 1997) and VW 7 50 73 (from August 2001).
Replacing the battery should be carried by a qualified workshop.
Please follow the instructions on the battery cover.
0 Note
• All work on the battery requires technical knowledge. Please
contact an Audi dealership or another authorized facility for ques­
tions about the battery -danger of acid burns and exp losion hazard!
• Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
• Battery holder and terminals always have to be secured correctly.
• Before all work on the battery follow the
warnings below=> & in
"Working on the battery" on
page 263.
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfuric acid and lead and must always be
disposed of properly in compliance with all environmental regula ­
tions . Disposing of vehicle batteries improperly is very dangerous to
the environment . Make sure that the removed battery cannot over ­
balance, otherwise sulfuric acid might escape!
[ i ] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced.•

[ 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 .
