For the sake of the environment
Because of the problem of proper disposal
of brake flu id as well as the special tools
required and the necessary expertise, we
recommend that 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 drives we recommend that you have
the electro lyte level checked by a service fa-
cility. The electrolyte level should also be
checked each time the battery is charged
¢ page 234.
Have the battery checked when you take your
vehicle in for service. You are well advised to
replace a battery that is older than 5 years .
With certain types of airbag deployment, the
battery is disconnected from the vehicle elec-
tr ical system for safety reasons ¢
&
in Re-
pair, care and disposal of the airbags on
page 161.
Disconnecting the battery terminals
Some vehicle functions (power window regu-
lators, for example) are lost if the battery ter-
minals are disconnected. These functions have
to be relearned after the battery terminals are
connected again. To prevent this , the battery
should only be disconnected from the vehicle
electrica l system when absolutely necessa ry
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo-
nents are gradually cut back or switched off.
This reduces energy consumption and main-
tains starting capabi lity over a longer period
¢ page 198. Some of the convenience func-
tions may not operate, such as the interior
lights or power seat adjustment. The conven-
ience functions will be available again when
you switch on the ignition and start the en-
gine.
Winter operation
During the winter months, battery capac ity
tends to decrease as temperatures drop. This
is because more power is also consumed while
starting, and the headlights, rear window de-
fogger, etc., are used more often.
Avoid unnecessary power consumption, par-
ticu larly in city traffic or when traveling only
short distances. Let your authorized Audi
deale r check the capacity of the vehicle bat -
tery before winter sets in ¢ page 234 . A well
charged battery will not only prevent star t ing
problems when the weather is cold, but will
also last longer .

weeks at extremely low temperatures, the
