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 or
via Plug & Charge. Observe the on-site operator's
instructions for the charging station and the notes
on Mercedes me Charge (see the vehicle's Digital
Owner's Manual).
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- Driving and parking

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 or
via Plug & Charge. Observe the on-site operator's instructions for the charging station and the notes
on Mer

cedes me Charge (see the vehicle's Digital
Owner's Manual).
The charging cable for the vehicle must not be
longer 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.
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,

to excessive charging current If the charging current is too high, the fuse
could be tr
ipped or the external mains supply
could overheat. 
Ensure that the external mains supply
has been designed t

o handle the charg-
ing current provided. 
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 Ser

vice Centre and obtain advice
there. 
Check the maximum charging current
using t

he charging capacity shown in the
driver's display. The charging cable supplied is set to a
countr
y-
speciNc maximum charging current value. When
charging abroad, the maximum value may exceed
the permitted value for that country. 
Before charging at a mains socket, have the
maximum per

missible charging current for the
relevant mains socket or the building inspec-
ted by a qualiNed electrician. 
When abroad, observe the countr
y-speciNc
laws when charging.

he charging cable, the vehicle socket or the
mains socket are damaged, you could receive
an electric shock. 
Only use an undamaged charging cable. 
Avoid mechanical damage such as crush-
ing, abr
ading or driving over the cable. 
Have a damaged vehicle socket replaced
at a q

ualiNed specialist workshop as
soon as possible. 
Never connect the charging cable to a
damag
ed vehicle socket. *
NOTE Damag
e due to overheating of
charging cable and charging cable con-
nector During the charging process, the charging
cable and c
harging cable connector can heat
up within their permissible limit values.
The permissible limit values are inOuenced by
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 Driving and parking
