ing.
= If the message does not turn off, drive immedi-
ately to an authorized Audi dealer or authorized

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
oh.
Multiple batteries with different technologies
may
be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 224, Safety
precautions
~ Auxiliary battery (for example, for recuperation
or optional equipment) > page 224, Safety pre-
cautions
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. 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 convenience
functions will be available again when you start
the engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
page 225. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places an especially high load on
the 12 volt vehicle battery. This results in re-
duced starting ability. Have the battery checked
by an authorized Audi dealer or authorized Audi
Service Facility before cold weather begins.
Replacing the battery
Applies to: 12 volt vehicle battery
All work on the battery must only be performed
by an authorized Audi dealer or authorized Audi
Service Facility.
The 12 volt vehicle battery was developed based
on the installation location and is equipped with
safety features. If a 12 volt vehicle battery must
be replaced, ask your authorized Audi dealer or
authorized Audi Service Facility about the electro-
magnetic compatibility, size, and the necessary
maintenance, power, and safety standards for
the new 12 volt vehicle battery. The battery vent
of the 12 volt vehicle battery must always be on
the negative terminal side. The battery vent on
the positive terminal side must always be closed.
When replacing the 12 volt lead-acid vehicle bat-
tery, only use a maintenance-free 12 volt lead-
acid battery that conforms to the TL 825 06 and
VW7 5073 standards. These standards must be
from October 2014 or newer.
= All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
