There are no malfunctions.
The high-voltage battery can
be charged.
Flashes red
The protective and indicator
system has detected a mal-
function due to an internal
malfunction. The high-voltage
battery cannot be charged.
If the control detects residual current or a mal-
function, the charging process is halted. Once
the malfunction has been rectified the charging
process is resumed automatically.
For information on problems relating to the
charging process, see (

Setting the maximum charge current
G
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.
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:
R
on the charging cable controls
R
in the
Settings
menu of the on-board com-
puter (
Y
page 273)
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:
R
it is not possible to set the charge current on
the charging cable
R
the precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
Setting the maximum permitted charge current
on the charging cable is described below.

If, after the charging process, the charging cable
is:
R
left connected to the power socket, the cur-
rently selected values will be used for the next
charging process.
R
removed from the power socket, the values
will be reset to the minimum setting for the
next charging process. You may then need to
reset the values of the maximum charge cur-
rent.

If the vehicle requires more time than usual
when charging, check the maximum charge
current settings using the controls on the
charging cable or in the on-board computer's
menu.
