Charging cable Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be damaged.
The vehicle is supplied with a single-phase 12 A charging cable. Only use the charging cable
included with the vehicle, which has been
approved for vehicle use.
Pay attention to the "Important safety notes"
(Y page 117).
If you use the supplied 12 A charging cable to
charge a high-voltage battery:
R the charge time increases considerably
R electrical consumption increases considera-
bly
Where possible, charge the high-voltage battery at a charging station (Y page 125). Only then
can certified electrical energy consumption lev- els be reached.
i The charging process can vary depending on
the charging station. Therefore, always
observe the local information.
Stowing the charging cable
The charging cable can be stowed in a bag in the trunk of the vehicle. To do so, the bag must be
secured to the cargo tie-down rings using the

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.
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 is the minimum
charge current setting. This corresponds to the
minimum available charge current from the
power supply.
i The value of the maximum setting and the
relevant adjustment values may vary depend-
ing on the country.
Before charging the high-voltage battery, have
the maximum permissible charge current for the High-voltage battery

relevant power socket checked by an electri-
cian.
X To adjust the setting: press button0085
repeatedly until the desired setting is selec-
ted in display 0087.
R Two LEDs are flashing: minimum setting
R All LEDs are flashing: maximum setting
Information about the charging time
(Y page 286)
If, after the charging process, the charging cable
is:
R left connected to the mains socket, the set
value will be used for the next charging proc-
ess.
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 charge current values that have been set
on the charging cable and the on-board com-
puter are different, the high-voltage battery is
charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:
R the settings of the maximum charge current
on the controls of the charging cable
