Always check wit h 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 bra kes as well as your
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 t hat you have the brake 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-
nance . With
high outside temperatures or
long daily dr ives we recommend that you have
the elec tro lyte level checked by a service fa-
cility. The e lect rolyte level sho uld a lso be
checked each time the battery is charged
¢ page 242.
Have the battery checked when you ta ke your
vehicle in for service. You are well adv ise d to
replace a battery that is older than S years .
With certa in types of airbag deployment, the
battery is d isconnected from the vehicle ele c-
tr ica l system for safety reasons¢
& in Re-
pair, care and disposal of the airbags on
page 165.
Disconnecting the battery terminals
Some veh icle func t ions (power window regu-
lato rs, for example) are los t if the bat t ery 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.
Vehicles not driven for long periods
If you do not drive 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
ligh t s or t he power seat adjus t ment. The con-
venience func t ions will be ava ilable ag ain
when you switch on t he ignition and start the
engine .
Winter operation
During the winte r months, battery capac ity
tends to de crease as t emperatures drop. This
is beca use more power is also consumed wh ile
sta rt ing, and the headlights, rear window de -
fogger, etc ., are used more often .
Avoid unnecessary power consumpt ion, par-
t icu lar ly in city traffic or whe n t raveling only
short distances. Let your au t horized Audi
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 will not freeze. This will
prevent it from be ing damaged and having
to be repla ced.
