Checking and Filling
Disconnecting the battery terminals
Some vehicle functions (power window regula
tors, for example) are lost if the battery termi
na ls are disconnected. These functions have to be
relearned after the battery terminals are con
nected again. To prevent this, the battery should
only be disconnected from the vehicle e lectrical
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, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and ma intains starting ca
pab ility over a longer period
c::> page 195 .
Take into consideration that when you unlock
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 available 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 be
cause more power is also consumed while start
ing, and the head lights, rear window defogger,
etc., are used more often.
Avoid unnecessary power consumption, particu
larly in city traffic or when traveling only short
d istances . Let your authorized Audi dealer check
the capacity of the vehicle battery befo re winter
sets inc::>
page 231. A well cha rged battery w ill
not only preven t starting problems when the
weather is cold, but will also last longer.

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 able to get to the bu lb.
This applies espec ially to the light bulbs in the
front of your ca r wh ich you can only reach
through the eng ine compartment.
2 6 8
Sheet meta l and bu lb 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 properly re
sealed.
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.
Ga s d ischar ge lam ps (Xeno n light s)*:
Due to the high e lectrica l voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light can be identified by the h igh
voltage 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 persona l injury and death .
- Xenon bulbs are pressur ized and can ex
plode when being changed .
- Changing Xenon lamps requires the special
tra ining, instruct ions and equ ipment .
- 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
ings and on the bulb ho lders that can cause
serious cuts.
- If you are uncertain about what to do, have
the wor k performed by an authorized Audi
dea ler or other qual ified workshop. Ser ious
personal injury may resu lt from improperly
performed work .
(D Tips
-If you must replace the light bulbs you rself,
always remember that the eng ine compart
ment of any vehicle is a hazardous area to
work in. Always read and heed all WARN
