Setting the maximum permissible charging cur-
r
ent for charging at a mains socket *
NOTE Ov
erloading the mains socket due
to excessive charging current If the charging current is too high, the fuse
could be tr
ipped or the external mains supply
could overheat. 
Make sure that the external mains supply
has been designed t

o handle the set
charging current. 
If necessary, reduce the set charging
cur
rent or use a diMerent mains socket. 
For safety reasons, only use the charging
cable supplied wit

h the vehicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables for their suitabil-
ity for high-voltage charging of your vehi-
cle. Purchase these parts at a Mercedes-
Benz Service Centre and obtain advice
there. 
Check the setting of the maximum
c
harge current using the charging capa-
city shown in the Instrument Display. Before charging at a mains socket, have the maxi-
mum per

missible charging current for the relevant
mains socket or the building inspected by a quali-
Ned electrician. The charging cable supplied is set
to a country-speciNc maximum charging current
value. When charging abroad, the maximum value
may exceed the permitted value for that country.
When abroad, observe the country-speciNc laws
when charging. If you have questions concerning
setting the charging current or if there is a mal-
function, please contact a qualiNed specialist
workshop. 
Set the maximum permissible charging cur-
r

ent in the multimedia system menu
( page 193).
If the exact value of the maximum permissible
c
harging current cannot be set, select the next
smaller adjustable value.
% If the vehicle requires more time than usual to
c

harge the high-voltage battery, check the maximum charging current settings in the
multimedia sy

stem menu. Overview of the charging cable control panel

To reset the charging cable operating unit: if
safety system 4 indicates a charging cable mal-
function or a vehicle malfunction, Nrst reset the
charging cable operating unit. To do this, discon-
nect the charging cable from the vehicle and from
the mains socket and wait for approximately Nve
seconds. If the malfunction persists aser the
charging cable is reconnected, charging at the
mains socket is not possible. The charging cable
must be replaced or the vehicle plug must be
checked at a qualiNed specialist workshop,

The permissible limit values are
inOuenced b y
the following factors:
= the power supply system and the charging
cable are not damaged
= the instructions for handling the charging
cable and the control element on the
charging cable have been observed 
If the charging cable or charging cable
connect

or becomes too hot, have the
power supply system checked. *
NOTE Damag
ed or dirty vehicle socket
when the socket Oap is open 
Always keep the socket cover and the
soc

ket Oap closed when there is no
charging cable connected. This protects
the vehicle socket from dirt and damage. 
Make sure that the socket cover is
closed pr

operly before closing the socket
Oap. This can otherwise result in damage
which may prevent the socket Oap from
being opened again. *
NOTE Damag

charging cable connector due to incorrect
handling Do not use excessive force (maximum 300 N)

vehicle socket to the stop. You may otherwise
damage the vehicle socket, the charging cable
connector or their contacts.

the socket and reinsert it. Requirements:
= The tr

ansmission is in position j.

between the key and the vehicle does not
exceed 1 m.
