WARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
!
An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
You can set a limit for the values of the charge
current used in charging the high-voltage bat-
tery. This acts as a means of preventing the
power supply from overloading. You can set this
limit by using the controls on the charging cable
or in the on-board computer's menu. Only set
the maximum charge current in the on-board
computer menu if there are no charge current
settings on the charging cable.
The default standard value in the vehicle corre-
sponds to the maximum charge current value.
The default standard value on the charging cable
is the minimum charge current setting. This cor-
responds to the minimum available charge cur-
rent from the power supply. The value on the
charging cable can be increased and is descri-
bed in the following section.
There are no malfunctions.
