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 amount of ene rgy 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
wo rkshop. N

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.
