should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains starting capab ility over a longer period
c;, page225.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con
venience functions will be available again
when you turn on the ignition 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 de
fogger, etc., are used more often .
Avoid unnecessary power consumption, par
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat
tery before w inte r sets in
¢ page 271. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.

weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
