Setting the maximum charge current
GWARNING
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.
Before starting the charging process at a power
socket, check the maximum permissible charge
current for the relevant power socket or the
building.
You can set the maximum permissible charge
current:
Ron the controls of the charging cable
Rin the Settingsmenu of the on-board com-
puter (Ypage 43)
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if:
Rit is not possible to set the charge current on
the charging cable
Rthe precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
How to set the maximum permissible charge
current on the charging cable, is described as
follows.
XTo adjust the setting: press button?
