Battery
Battery general information
Because of the complex power supply, all work
on batteries such as disconnecting, replacing,
etc., should only be performed by an authorized
Audi dealer or authorized Audi Service Facility
oA.
Batteries with different technologies are instal-
led in your vehicle:
— 12 volt vehicle battery (for example, for basic
power supply) page 259, Safety precautions
—High-voltage battery (for example, for electric
drive system, climate control) © page 173, In-
troduction
Not running the vehicle for long periods of
time
If the vehicle is left parked for long periods of
time, the 12 volt vehicle battery will drain gradu-
ally. To ensure that the vehicle can still be start-
ed, the electrical equipment will be limited or
switched off. Some convenience functions, such
as interior lighting or power seat adjustment,
may not be available under certain circumstan-
ces. The convenience functions will be available
again when you establish drive ready mode.
Even when electrical equipment is switched off,
the equipment can still drain the 12 Volt vehicle
battery if the vehicle is not driven for long peri-
ods of time. Deep draining results in a chemical
reaction that destroys the inside of the battery.
To reduce the risk of this, the battery must be
charged monthly by an authorized Audi dealer or
authorized Audi Service Facility page 260. Con-
tact an authorized Audi dealer or authorized Audi
Service Facility for more information.
Winter operation
Cold weather places an especially high load on
the 12 volt vehicle battery. Have the battery
checked by an authorized Audi dealer or author-
ized Audi Service Facility before cold weather be-
gins.
