Checking and filling -
---------------------=----"=---------
checked by a service facility. The electrolyte level should also be
checked each time the battery is charged =>
page 323.
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 discon­
nected from the vehicle electrical system for safety reasons=>.& in
"Repair, care and disposal of the airbags" on
page 234.
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 again. 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 vehicle over a period of several 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 276.
Be aware that when you unlock your vehicle, some of the conve ­
nience functions may not operate, such as the Convenience key*,
the remote control or the power seat adjustment. The convenience
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 defogger, etc., are
used more often.
Avoid unnecessary power consump tion, 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 323. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i] Tips
If your vehicle 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.•
Working on the battery
Be especially careful when working on or near the battery.
