Notes on charging the high-voltage battery at a
w
allbox or charging station (mode 3) &
DANGER Risk of f
atal injury from incor-
rectly installed component parts
Connecting the charging cable to a wallbox
using incor
rectly installed component parts
could cause a Nre or an electric shock, for
example. 
Only connect the charging cable to a
w
allbox that:
= Has been pr
operly installed and
= Has been inspected by a qualiNed electri-
cian 
For safety reasons, only use charging
cables t

hat have been tested and
approved by the manufacturer for charg-
ing the high-voltage battery in an electric
vehicle. 
Never use damaged charging cables. 
Do not extend the charging cable. 
Do not use adapters. 
Observe the safety notes in the operat-
ing ins
tructions for the wallbox. If charging at a wallbox without pre-installed
cable, use t

he optionally available charging cable
for wallbox and charging station (mode 3). The
charging cable is stowed in a bag in the boot/
luggage compartment.
Only use charging cables that have been tested
and approved by the manufacturer for charging
the high-voltage battery in an electric vehicle. &
DANGER Risk of f
atal injuries due to dam-
aged components
Connecting the charging cable to a charging
s
tation using a damaged component part
could cause a Nre or an electric shock, for
example. 
For charging stations with a preinstalled
c

harging cable:
= Perform a visual check of the charg-
ing station for obvious faults, such as
massive damage to the housing or
charging cable. 
For charging stations without a preinstal-
led c

harging cable:
= For safety reasons, only use charging
cables that have been tested and
approved by the manufacturer for
charging the high-voltage battery in
an electric vehicle.
= Never use damaged charging cables.
= Do not extend the charging cable.
= Do not use adapters. 
Make sure to observe the safety informa-
tion on t

he charging station. Most charging stations must be activated before
t

he charging process, e.g. using an RFID card.
Observe the on-site operator's instructions for the
charging station.
The amount of energy dispensed for the charging
process, shown by the charging station, may be
higher than the amount of energy actually absor-
bed by the high-voltage battery. This is the result
of diMerent levels of charging losses and is descri-
bed as recharge ePciency. Charging losses occur,
for example, due to heat that builds up when the 228

DANGER Risk of f
atal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-boar
d electrical system is under high volt-
age. 
Do not perform any maintenance work
dur

ing the charging process. Most charging stations must be activated before
t

he charging process, e.g. using an RFID card.
Observe the on-site operator's instructions for the
charging station. The charging cable for the vehicle must not be
long
er than 30 m due to the legal requirements in
some countries. This is to prevent the interfer-
ence of signals being received by radio communi-
cation devices in the vehicle or in close proximity
to the charging station. Be aware that parts of the
charging cable may be routed underground. If in
doubt, ask the charging station operator if this is
the case before charging the high-voltage battery.

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 349).
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,
depending on the indicator. Functions of the indicator lamps on the vehicle

At the start of the charging process, the charge
level display is shown in the Instrument Display
with a charging prediction. The charging predic-
tion either refers to the predicted charge level at
the set departure time, or the time at which the
high-voltage battery will be fully charged.
% Depending on the temperature, the fan and
batt

ery cooling system may audibly switch on
during the charging process.
% If the vehicle is idle for lengthy periods and
connect
ed to the mains supply, the high-volt-
age battery will be recharged automatically as
needed or when electrical consumers are
activated (e.g. the pre-entry climate control). %
The vehicle is equipped with an electrical fuse
whic
h protects it against overvoltage in the
mains supply. This electrical fuse may trip dur-
ing severe thunderstorms, for example, and
may cause the fuse in the building to trip or
may interrupt the charging process. These
functions protect the vehicle.
Aser the fuse in the building is switched on
again, the charging process resumes automat-
ically. Following an interruption in the power
supply without the fuse in the building being
tripped, it may take up to ten minutes for
charging to resume automatically. Ending the alternating current charging process
