First charge and charging after a long time
If the high-voltage battery is new or has not
been charged for a long time, the maximum
charge level of the battery can only be
reached after several charging processes.
This is for technical reasons and is not a vehi-
cle malfunction.
If the vehicle is not used for a long period of
time, the high-voltage battery must be
charged at least once every four months.
Note
If you leave the charging cable connected
after charging, the vehicle's electrical con-
sumers will not drain the high-voltage bat-
tery.
