Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating condit ions, the battery in your Aud i does not
need any maintenance. With
high outside temperatures or long daily
drives we recommend that you have the electrolyte level checked by
a service facility. The electrolyte level should also be checked each
time the battery is charged~
page 292.
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 a irbag deployment, the battery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 211.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in. To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period~
page 249.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func­
tions will be available again when you turn on the ign ition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are used more often .
Avoid unnecessary power consumpt ion, particu larly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before w inter sets in
=> page 292. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longe r.
(I] Tips
If your veh icle is left standing for several weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced.•
