General information
Unde r normal operating conditions, the bat ­

nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec­

page 224.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .

Disconnecting the battery terminals
Some veh icle functions (power w indow regu­
lato rs, for example) are lost if the battery ter­
m inals a re discon nected. These functions have
to be re lea rned after the batte ry terminals a re
connec ted agai n. T o prevent this, the battery
should o nly be d isconnec ted from the vehicle
e lec trica l syste m when absolu tely necess ary

Winter operation
Du ring the w inte r mon ths , b att ery capac ity
tends to dec rease as temperatures drop . This
is beca use more power is a lso consumed w hile
starting, and the headlights, rear win dow de­

ticu lar ly in ci ty traffic o r when traveling only
sho rt distances . Let yo ur autho rized A udi

charged battery will not on ly prevent starting
problems when the weather is cold, but will

Bulbs
Replacing bulbs
For your safety, we recommend that you hove
your authorized Audi dealer replace any 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 holders can have sharp
edges that can cause serious cuts, parts must
be correctly taken apart and then properly put
back together to help prevent breakage of
parts and long term damage from water that
can enter housings that have not been p roper­
l y resea led.
For your safety, we recommend that you have
you r authorized Aud i dea ler replace any bulbs
for you, since yo ur dealer has the proper too ls,
the correct bulbs and the expertise .
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the
bulbs replaced by a qualif ied techn ic ian.
Headlights wit h Xenon light are identified by
the high voltage sticker.
_&. WARNING
Changing Xenon lamps witho ut the neces­
sa ry equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
