Notes on charging the high-voltage battery
at a wallbox or charging station (mode 3)
& DANGER Risk of fatal injury from incor‐
rectly installed component parts
Connecting the charging cable to a wallbox
using incorrectly installed component parts
could cause a fire or an electric shock, for
example.
Only connect the charging cable to a
#
wallbox that:
Has been properly installed and
R
Has been inspected by a qualified electri‐
R
cian
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.
#
Observe the safety notes in the operat‐
#
ing instructions for the wallbox.
If charging at a wallbox without pre-installed
cable, use the 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 fatal injuries due to
damaged components
Connecting the charging cable to a charging
station using a damaged component part
could cause a fire or an electric shock, for
example.
For charging stations with a preinstalled
#
charging cable:
Perform a visual check of the charg‐
R
ing station for obvious faults, such
as massive damage to the housing
or charging cable.

For charging stations without a prein‐
#
stalled charging cable:
For safety reasons, only use charg‐
R
ing cables that have been tested
and approved by the manufacturer
for charging the high-voltage battery
in an electric vehicle.
Never use damaged charging
R
cables.
Do not extend the charging cable.

Make sure to observe the safety infor‐
#
mation on the charging station.
Most charging stations must be activated before
the charging process, e.g. using an RFID card.
Observe the on-site operator's instructions for
the charging station.
The amount of energy dispensed for the charg‐
ing process, shown by the charging station, may
be higher than the amount of energy actually
absorbed by the high-voltage battery. This is the
result of different levels of charging losses and is
described as recharge efficiency. Charging los‐
