Disconnecting the battery terminals
Some vehicle functions (power window regula
tors , for example) are lost if the battery termi
nals are disconnected. These functions have to be
re learned after th e battery terminals are con
nected again. To prevent this, the batte ry should
only be disconnected from the ve hicle electrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca pability over a longer period
c:> page 196.
Take into consideration that when you un lock
your veh icle, some convenience functions, such
as the interior lights or the power seat adjust
ment, may not be available . The convenience
functions will be ava ilable again when you turn
on the ignition and start the engine.
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, part icu
larly in city traffic or when traveling only short
d istances . Let your authorized Aud i dealer check
the capacity of the vehicle battery before w inter
sets in
c:> page 232. A well charged battery will
not only prevent s tarting problems when the
weather is cold, but will also last longer.
Working on the battery

the battery.
The battery is located in the luggage compart
ment under the floor. Before you check anything

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are ab le to get to the bulb.
This applies espec ially to the light bulbs in the
front of you r car which you can only reach
through the engine compartment.
Fuses and bulbs
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
must be correctly taken apart and then properly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been proper ly re
sealed .
For your safety, we recommend that you have
your authorized Aud i dealer replace any bulbs for
you, since your dealer has the proper too ls, the
correct bulbs and the expertise .
Gas discharge lamps (Xenon lights )*:
Due to the high e lectrica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light can be identif ied by the high
vo ltage sticker.
A WARNING
Contact with high-voltage components of the
electr ical system and improper replacement
of gas discharge (Xenon) headlight bulbs can
cause ser ious personal injury and death.
- Xenon bulbs are pressur ized and can ex-
plode when being changed.
- Changing Xenon lamps requ ires the special
train ing, instructions and equipment.
- Only an authorized Audi dealer or other
qualified workshop should change the bulbs
in gas discharge lamps.
A WARNING "'--
There are parts with sharp edges on the open-
in gs and on the bulb holders that can cause
serious cuts.
- If you are uncertain about what to do, have
the wor k performed by an authorized Aud i
dealer or other qualified workshop. Serious
personal injury may resu lt from improperly
performed work .
(D Tips
-If you must replace the light bulbs yourself,
always remember that the engine compart
ment of any vehicle is a hazardous area to
work in . Always read and heed all WARN
