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
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 ca r 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 cor rectly 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 housings that have not been
properly re sea led.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified techn ic ian.
Head lights with Xenon light can be identified
by the high voltage sticker.
_& WARNING ~
Contact with high-vo ltage 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 pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .

CD Note
-Applying a higher vo ltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays , radio, etc.
- There must be no e lectrica l contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
pos itive(+) terminals are connected.
- Improper ly connected jumper cables can
cause substantial damage to the electri­
ca l system of the vehicle .
(D Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem.
