Battery
eae elec acl)
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 > A\.
Batteries with different technologies are instal-
led in your vehicle:
— 12 volt vehicle battery (for example, for basic
power supply) > page 238, 12 Volt vehicle bat-
tery
— High-voltage battery (for example, for electric
drive system, climate control) > page 108, In-
troduction
Not running the vehicle for long periods of
time
When the vehicle is not used for long periods, the
12 Volt vehicle battery will drain little by little. To
ensure that the vehicle can still be started, 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 circumstances. The con-
venience 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 239. 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-
238
ized Audi Service Facility before cold weather be-
gins.

ZA WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical
burns, accidents, or burns. Because of this, all
work must be performed only by an author-
ized Audi dealer or authorized Audi Service Fa-
cility.

ZA WARNING
