Di sconnect ing the batt ery terminal s
Some vehicle functions (power window regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng period s
If you do not drive your vehicle over a period
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
~ page 182.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment . The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling only
short d istances . Let you r authorized Audi
dealer check the capacity of the vehicle bat­
tery before winte r sets in
~ page 219. A well
charged battery w ill not only prevent starting
prob lems when the weather is cold, but wi ll
a lso last longer .
