Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any 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 especially to the light bulbs in the
front of your car which you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
Fuses and bulbs
correctly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
hous ings that have not been properly resealed.
For your sa fety, 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 lamps (Xenon lights)*:
Due to the high e lectr ica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light)* life-threatening injuries
can resu lt from improper handling of the
high -vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts w ith
sharp edges on the openings and on the bulb holders that can cause serious cuts . If
you are uncerta in about what to do, have
the wor k performed by an authorized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be awa re that the engine compa rt­
ment is a hazardous area to work
inq page 203 q &,.
- It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
