Charging the high-voltage battery
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

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 vehicle
via an incorrectly installed wallbox or by
means of adapters, extension cables or simi-
lar 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 if: -
the wallbox is properly installed -
the wallbox has been inspected by a
qualified electrician -
the charging cable is not damaged. R
Do not extend the charging cable. R
Do not use an adapter. R
Always observe the safety notes in the wall-
box's operating instructions.
The vehicle's high voltage electrical system is
under high voltage. R
Do not tamper with the high-voltage compo-
nents or the orange cables of the high-voltage
electrical system. R
Do not touch high-voltage components or the
orange cables of the high-voltage electrical
system when a vehicle has been involved in a
crash.Charging the high-voltage battery 29

damaged orange cables of the high-voltage
electrical system. R
Do not remove the covers of the high-voltage
electrical system components that are
marked with a warning sticker.
General notes
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode, kinetic energy is converted by
means of energy recuperation into electrical
energy and stored in the high-voltage battery.
Information on overrun mode ( Y
page 24).
The high-voltage battery can be charged as fol-
lows: R
through energy recuperation while the vehicle
is in motion R
through the combustion engine while driving
in CHARGE operating mode ( Y
page 21)R
with the relevant charging cable at an electri-
cal outlet while the vehicle is stationary R
at a wallbox while the vehicle is stationary R
at a charging station while the vehicle is sta-
tionary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
You can view the condition of charge of the high-
voltage battery in the multifunction display.
Information about this can be found under
"Energy flow display" ( Y
page 40).
High and low outside temperatures Low outside temperatures
At very low outside temperatures the maximum
power output of the high-voltage battery may be
reduced. The high-voltage battery is then no
longer able to provide the normal electrical
power output.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced by the vehicle.
Energy consumption and electrical
range The maximum electrical range is generally
reduced by: R
high and low outside temperatures R
operating the climate control system R
switching on consumers
The battery's physical characteristics are such
that leaving the vehicle parked for long periods
at low outdoor temperatures without charging it
can lead to: R
a reduction in battery performance R
longer charge times
Notes on battery care Avoid storing or transporting the vehicle at
excessively high or low temperatures over a long
period.
If you park the vehicle and leave it stationary for
long periods: R
check the condition of charge of the high-
voltage battery more often R
connect the vehicle to a power supply
This prevents self-discharge and damage to the
high-voltage battery.
Terms of use Please note the information on exceptions and
limitations in warranty documentation and in
the Maintenance Booklet.
Handling the charging cable and charg-
ing cable controls Always read the notes on the charging cable on
the inside of the charge socket flap.
Do not leave the charging cable controls
( Y
page 32) 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.30

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 charging
cable 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 29).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and the charging cable con-
nector will only heat up within the permissible
limiting 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
If the charging cable or charging cable connec-
tor become too hot, have the mains power sup-
ply checked.
Protection device against overvoltage
! Overvoltage in the mains supply may dam-
age the vehicle. For this reason, the vehicle is
equipped with a protection device against
overvoltage in the mains supply. This device
may be triggered during severe thunder-
storms, for example, and may lead to the buil-
ding's fuse being tripped and an interruption
in the power supply. These functions protect
the vehicle. After the building fuse is switched
on again, the charging process resumes auto-
matically. Following an interruption in the
power supply or tripping of the building's fuse,
it may take up to 10 minutes for charging to
resume automatically.
Switch on the building protection system again
after it has been triggered. Otherwise, the
charging process cannot be continued. General information about the charging
procedure Pay attention to the "Important safety notes"
( Y
page 29).
The vehicle socket is located in the rear bumper
on the right below the tail lamp.
The charge socket flap and the vehicle are cen-
trally locked or unlocked simultaneously.

i If you use the supplied 12 A charging cable
to charge a high-voltage battery: R
the charge time increases considerably R
electrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station ( Y
page 35). Only
then can certified electrical energy consump-
tion levels be reached.
