24 0 Ch eck ing and filling
Always check wi th your a uthorized Audi
dealer to make s ure you are using the
correct brake flu id. The correct type of
brake fluid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can ser ious ly affect the effi­
ciency of the b ra kes as well as yo ur
safety. This could result in an acc ident.
(D Note
Brake flu id will damage the paint of your
veh icle.
@ For the sake of the environment
Because of the problem of proper d isposa l
of brake flu id as wel l as the special tools
requ ired and the necessary expert ise, we
recommend that you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
Under
normal operating conditions, the bat­
tery in your Audi does not need any mainte­
n ance . With
high outside temperatures or
l ong daily dr ives we recommend that you have
the elec trolyte level checked by a service fa­
cili ty. The e lec trolyte level sho uld a lso be
checked each time the battery is charged
¢ page 242.
Have the b attery checked when you ta ke yo ur
ve hicl e in for service. Yo u are well adv ise d to
replace a battery that is older than S years .
W ith certa in types of airbag deployment, the
battery is d isconnected from the vehicle ele c­
tr ica l system for sa fety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 165.
Disconnecting the battery terminals
Some veh icle func tions (power w indow regu­
l ato rs, for example) a re los t if the b attery ter- mina
ls are disconnected. These functions have
to be relearned after the battery termina ls are
connected aga in. To prevent th is, the battery
sho uld only be disconnected from the ve hicle
electrical system when abso lutely necessary
for repairs.
Vehicle s not driven for long peri ods
If you do not d rive your vehicle over a period
of several days or weeks, e lectr ica l compo ­
nents are gradually cut back or sw itched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer period
¢
page 202. Some of the convenience func­
t ions may not ope rate, such as the inter ior
li gh ts or the power seat adjus tment. The con­
venience func tions will be ava ilable ag ain
when you switch on the ignition and start the
engine .
Winter operation D uring the winte r months, battery capac ity
tends to de crease as temperatures drop. This
is beca use more power is also consumed wh ile
sta rting, and the headlights, rear window de ­
fogger, etc ., are used more often .
Avoid unnecessary power consumpt ion, p ar­
t icu lar ly in city traffic or whe n traveling only
short distances. Let yo ur au thorized Aud i
dealer check the capacity of the vehicle bat ­
tery before winter sets in ¢
page 242. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
(!) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be repla ced.

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 s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s applies especially to the light bu lbs
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 ser ious 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 housings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be ident ified
by the high voltage sticke r.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb 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 ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious 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 improperly performed work.
(D Tips
-If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. Always read and
heed all WARNINGS
c> page 228.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
