Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becom ing increasingly more and more diffi­
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are ab le to get to the bulb.
This applies especially to the light bulbs in the
373

Fuses and bulb s
front of your car which you can on ly reach
through the engine compartment .
Sheet metal and bulb ho lde rs can have s ha rp
edges that can cause ser ious c uts, parts must be
correct ly taken apart and then properly put back
together to he lp prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resea led.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bu lbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Ga s di sch arg e lamps (Xen on li ght s)
Due to the high elect rical voltage, have the bulbs
replaced by a qua lified technic ian . Head lights
with Xenon light are ident ified by the h igh vo lt ­
age sticker.
LED h eadlight s*
LED headlights require no maintenance . Please
contact your authorized Audi dealer if a bulb
needs to be replaced .
A WARNING
Chang ing Xenon lamps w it h out the necessa ry
equ ipment can cause ser ious perso na l inju ry.
- Bul bs are p ressur ized and can explode when
being changed. Potentia l risk of i njury!
- On vehicles equipped wit h gas discharge
bulbs (Xenon light) life-threatening inju ries
can result from imp roper ha ndl ing of the
high -voltage po rtions of su ch lamps!
- Only yo ur auth o rized Aud i dea le r or q ual i­
fied workshop should change the b ulbs in
gas discharge lamps . There a re parts with
sharp edges on the openings and on the
bulb ho lders t hat can cause serious cuts . If
you are uncertain about what to do, have
the work performed by an authorized A udi
dealer or qualified workshop. Serious per­
sonal injury may resu lt from improperly per­
formed work .
(D Tips
-If you still prefer to rep lace the light bu lbs
yourself, be aware that the engine com part-
374
ment is a hazardous area to work in ¢ & in
Working in the engine comportment on
page 318 .
-It is best to ask your a uthorized Audi dea ler
whenever you want to change a bulb .
