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
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 ho lders 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 break ­
age of parts and long term damage from wa­
ter that can enter hous ings that have not been
properly resealed.
For your safety, we recommend that you have
your author ized 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 vo ltage, have the
bulbs replaced by a qualified technician.
H eadlights with Xenon light can be identified
by the high voltage sticker.
LED headlights* require no maintenance .
Please contact your authori zed Audi dealer if a
bulb needs to be replaced.
A WARNING
Contact with high-voltage components of
the 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.
- Changing Xenon lamps requires the spe­
cial training, instructions and equip­ ment.
- Only an authorized A udi dealer or other
qualified 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 ser ious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from imprope rly performed wo rk.
(D Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS¢
page 216, Engine
compartment¢ &..
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
