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

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
VW 7 SO 73 standards. These standards must be
from October 2014 or newer.

ly. Otherwise, there could be a loss of safe-
ty-related functions among other things,
which increases the risk of an accident.
