riods, longer than a month.
Hints
Do not connect charging devices to the
12 volt socket in the vehicle

increased power consumption.◀
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 218, in the
engine compartment with the engine off.
Power failure After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e. g.:▷Seat and mirror memory: store the posi‐
tions again.▷Time: update.▷Date: update.▷Glass sunroof and sliding visor: initialize
the system, refer to page 48.
