The various electrical circuits are protected by
fuses. The fuses are clustered in a centralized unit. The unit is located behind the face panel
at the end of the instrument panel.
You are well advised to keep a supply of spare
fuses in your vehicle. Fuses with the proper
ampere rat ings are ava ilable at your author ­
ized Audi dealer.
A WARNING -
Do not repa ir fuses and never replace a
blown fuse with one that has a higher amp
rating. This can cause damage to the elec­
trica l system and a fire.
(D Note
If a new fuse burns out again after shortly
have you have installed it, have the electri­
ca l system checked by your authorized
Audi dealer.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authori zed 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 . Th is appl ies especially to the l ight bulbs
in the front of your car which you can only
reac h through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
e rly put back together to help p revent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your author ized Audi dealer replace any bu lbs
for you, since your dealer has the p roper tools,
the correct b ulbs and the expertise.
Ga s di sc harg e lamp s (Xeno n light s}*:
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
A WARNING
Contact with high-voltage components of
t he electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death .
- Xenon bulbs are pressurized and can ex­
plode when being changed.
Fu ses and bulb s 231
-Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualif ied workshop should change the
bulbs in gas discharge lamps .
A WARNING .,.;
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious c uts.
- If you are uncertain about what to do,
have the work performed by an a uthor­
ized Audi dealer or othe r qualified work­
shop. Ser ious personal in ju ry may result
from imprope rly performed work.
(D Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
c ompartment of any vehi cle is a hazard­
ous area to work in. A lways read and
heed all WARN INGS
~page 174, Engine
compartment ¢&, .
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
