Connecting thech arging cable toach arging
station using a damaged component part
could cause a /re or an elect ric shoc k,for
ex ample. #
Forch arging stations with a preinstalled
ch arging cable:
R Perform a visual check of thech arg-
ing station for obvious faults, such as
massive damage tothe housing or
ch arging cable. #
Forch arging stations without a preinstal-
led charging cable:
R For saf etyre asons, only use charging
cables that ha vebeen tested and appro
vedby the manufacturer for
ch arging the high-voltage battery in
an electric vehicle.
R Never use damaged charging cables.
R Do not extend thech arging cable.
R Do not use adap ters. #
Make sure toobser vethe saf ety in form a-
tion on thech arging station. Most
charging stations must be activated before
th ech arging process, e.g. using an RFID card.
Obser vethe on-site operator's inst ructions forthe
ch arging station.
The charging cable forth eve hicle must not be
lon gerth an 30 m due tothe legal requ irements in
some countries. This is toprev ent the inter fer-
ence of signals being received byradio communi-
cation devices in theve hicle or in close pr oximity
to thech arging station. Be awarethat parts of the
ch arging cable may be routed under ground. If in
doubt, ask thech arging station operator if this is
th e case before charging the high-voltage batter y.
The amount of energy dispensed forth ech arging
process, shown bythech arging station, may be higher
than the amount of energy actually absor-
bed bythe high-voltage batter y.This is there sult
of di.erent le vels of charging losses and is descri-
bed as rech arge e1ciency. Charging losses occur,
fo rex ample, due toheat that builds up when
ch arging or from auxiliary consumers that are
switched on. Further information on rech arge e1-
ciency can be obtained at a quali/ed specialist

For saf etyre asons, only use thech arging
cable supplied with theve hicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables forth eir suitabil-
ity for high-voltage charging of your vehi-
cle. Pur chase these parts at a Mercedes-
Benz Service Centre and obtain advice
th ere. #
Check the maximum charging cur rent
using thech arging capacity shown in the
driver's displa y. The
charging cable supplied is set toa countr y-
speci/c maximum charging cur rent value. When
ch arging abroad, the maximum value may exceed
th e permitted value forth at countr y. #
Before charging at a mains soc ket, ha vethe

If th ech arging cable, theve hicle soc ket or the
mains soc ket are damaged, you could receive
an elect ric shoc k. #
Only use an undamaged charging cable. #
Avoid mechanical damage such as crush-
ing, abrading or driving overth e cable. #
Have a damaged vehicle soc ketre placed
at a quali/ed specialist workshop as
soon as possible. #
