MERCEDES-BENZ C-CLASS ESTATE 2022 Owners Manual

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
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,
for example, due to heat that builds up when the
vehicle is charging or from auxiliary consumers
that are switched on. Further information on
recharge ePciency can be obtained at a qualiNed
specialist workshop. Setting the maximum permissible charging cur-

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. 
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.
If you have questions concerning the charging
cur
rent or if there is a malfunction, please contact
a qualiNed specialist workshop. Overview of the charging cable control panel

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,

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 
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
t
he 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. *

When the charging cable is connected to the vehi-
cle, t
he vehicle cannot be started or moved.
At the start of the charging process, the charge
level display is shown in the driver's display with a
charging prediction. The charging prediction
refers to the time at which the high-voltage bat-
tery 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 pr

otect 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

DANGER Risk of deat h when charging at a
damaged socket
The charging process uses high voltage.
If t
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. *
