Have the battery checked when you take your vehicle in for service.
You are well advised to rep lace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle e lectrical system for safety reasons =>
& in "Repair,
care and disposal of the airbags" on
page 199.
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 dr ive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains start ing capability over a
longer period => page 235.
Take into consideration that when you unlock you r 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.
W inter operation
During the winte r months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
wh ile starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
=> page 280. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer .
W Tips
If your veh icle is left standing for several weeks at extremely 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 . •
