206 Driving and parking
Always observe the safety information on
#
the charging station.
& DANGER Risk of fatal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-board electrical system is under high volt-
age.
Do not perform any maintenance work
#
during the charging process.
Most charging stations must be activated before
the charging process, e.g. using an RFID card or
via Plug-and-Charge. Observe the on-site opera-
tor's instructions for the charging station and the
notes on Mercedes me Charge (see the vehicle's
Digital Operator'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 different levels of charging losses and is descri-
bed as recharge efficiency. 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 efficiency can be obtained at a qualified
specialist workshop.
Setting the maximum permissible charging cur-
rent for charging at a mains socket
* NOTE Overloading the mains socket due
to excessive charging current
If the charging current is too high, the fuse
could be tripped or the external mains supply
could overheat.
Ensure that the external mains supply
#
has been designed to handle the charg-
ing current provided.
For safety reasons, only use the charging
#
cable supplied with 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 center and obtain advice
there.
Check the maximum charging current
#
using the charging capacity shown on
the driver's display.
The charging cable supplied is set to a country-
specific 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 permissible charging current for the
relevant mains socket or the building installa-
tion checked by a qualified electrician.
When charging abroad, observe the country-
#
specific laws.
If you have questions concerning the charging
current or if there is a malfunction, please contact
a qualified specialist workshop.
