Important safety notes
G
DANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high- voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
DANGER
Connecting the charging cable to the mains
supply via incorrectly installed mains sockets or by means of adapters, extension cables or similar could cause a fire or an electric shock.
There is a risk of fatal injury.
To avoid hazardous situations, observe the
following:
R Only connect the charging cable to mains
sockets:
- which have been properly installed and
- which have been inspected by a qualified
electrician
R For safety reasons, only use the charging
cables supplied with the vehicle, or charg-
ing cables which have been approved for
use with this vehicle.
R Never use a damaged charging cable.
R Do not use:
- extension cables
- extension reels
- multiple sockets
R Never use socket adapters to connect the
charging cable to the mains socket. The
only exception being if the adapter has
been tested and approved by the manufac-
turer for charging the high-voltage battery
of an electric vehicle.
R Observe the safety notes in the operating
instructions for the socket adapter. G
DANGER
Connecting the charging cable to the wallbox via an incorrectly installed wallbox or adapter,
extension cable or similar could cause a fire or an electric shock. There is a risk of fatal injury.
To avoid hazardous situations, observe the
following:
R Only connect the charging cable to a wall-
box that:
- is installed correctly and
- has been inspected by a qualified elec-
trician

Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
(Y
page 123) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.
To ensure that the brackets within the charging cable controls are not subjected to incorrect
loads, observe the following:
R Never lift or carry the controls by the charging
cable connector or the mains plug.
R To transport the charging cable, the coiled
part can be:
- wrapped around the controls or
- secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Pay attention to the important safety notes
(Y page 117).
During the charging process, the charging cable
and charging cable connector may heat up. The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting values, provided that:
R the power supply and the charging cable are
not damaged
R the instructions for handling the charging
cable and controls on the charging cable are
observed
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Electrical fuse against overvoltage !
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
electrical fuse against overvoltage has been
tripped. Otherwise, the charging process cannot
be continued. The high-voltage battery will not
be charged and you may not be able to drive the vehicle.
If other devices are protected by the same pro-
tective device, these are switched off as well
when the protective device is triggered. Ensure
that these other devices are still operational
after reactivating the protection device. 118

Setting the maximum charge current G
WARNING
If the charge current draw via a mains socket is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
! An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
You can set a limit for the values of the charge
current used in charging the high-voltage bat-
tery. This acts as a means of preventing the
power supply from overloading. You can set this limit by using the controls on the charging cable
or in the on-board computer's menu. Only set
the maximum charge current in the on-board
computer menu if there are no charge current
settings on the charging cable.
The default standard value is the minimum
charge current setting. This corresponds to the
minimum available charge current from the
power supply.
i The value of the maximum setting and the
relevant adjustment values may vary depend-
ing on the country.
Before charging the high-voltage battery, have
the maximum permissible charge current for the High-voltage battery

Information about the charging time
(Y page 286)
If, after the charging process, the charging cable
is:
R left connected to the mains socket, the set
value will be used for the next charging proc-
ess.
R removed from the power socket, the values
will be reset to the minimum setting for the
next charging process. You may then need to
reset the values of the maximum charge cur-
rent.
If the charge current values that have been set
on the charging cable and the on-board com-
puter are different, the high-voltage battery is
charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:
R the settings of the maximum charge current
on the controls of the charging cable
