checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceeda critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger area 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 such risks, 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 charging
cables which have been supplied with the
vehicle or which have been approved for
this vehicle.
R Never use a damaged charging cable.
R Do not use:
- extension cables
- extension reels
- multi-outlet sockets
R Never use socket adapters to connect the
charging cable to the mains socket. The
only exception is if the adapter has been
tested and approved by the manufacturer
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 mains
supply via an incorrectly installed wallbox 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 Wallbox without pre-installed cable: 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.
R Only connect the charging cable if the wall-
box:
- has been properly installed and
- has been inspected by a qualified elec-
trician.
R Never use damaged charging cables.

Operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores Charging the high-voltage battery
183Driving and parking Z

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 269).
The high-voltage battery can be charged as fol-
lows:
R through energy recuperation while the vehicle
is in motion
R during the journey by the combustion engine
in CHARGE operating mode (Y page 262)
R with the relevant charging cable at a mains
socket while the vehicle is stationary
R with the relevant charging cable at a wallbox
while the vehicle is stationary
R with the relevant charging cable at a charging
station while the vehicle is stationary
The high-voltage battery can be charged in a
nominal voltage range from 100 Vto 240 V.
You can view the charge status of the high-volt-
age battery in the multifunction display. You can
find information in "PLUG-IN HYBRID opera-
tion", section "Menus and submenus" under
"Energy flow display" (Y page 263).
High and low outside temperatures Low outside temperatures
The maximum performance of the high-voltage
battery is significantly reduced at very low out-
side temperatures. The high-voltage battery is
then no longer able to provide the normal elec-
trical 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 charge status 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 the warranty documentation and
in the Service Booklet.
Handling the charging cable and charg- ing cable controls Do not leave the charging cable controls
(Y
page 185) hanging loose from a mains
socket. Otherwise, this could result in a poor
contact with the mains socket and malfunctions
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 charging
cable can be:
- charging cable variant 1: wrapped around
the controls or secured to the control hous-
ing.
- charging cable variant 2: wrapped around
the controls and secured with a strap
Information on charging cable variants can be
found under "Charging cable for mains sockets"
(Y page 185). 184
Charging the high-voltage batteryDriving and parking

Heat generated by the charging cable
and charging cable connector Observe the "Important safety notes"
(Y
page 182).
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 mains 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 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 or tripping of the
building's fuse, it may take up to 10 minutes
for charging to resume automatically.
Reset the building's circuit breaker. Otherwise,
the charging process cannot be continued.
General information on the charging
process Observe the "Important safety notes"
(Y page 182).
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. Charging the high-voltage battery via

Charging cable for mains sockets Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charging cable for other purposes. It may otherwise be damaged.
The vehicle is supplied with a country-specific
charging cable, variant 1 or variant 2, for con-
nection to a mains socket. The controls of the
two charging cable variants are different. Only
use the charging cable supplied with the vehicle
or a charging cable approved for the vehicle.
i The charging process can vary depending on
the mains power supply. Therefore, always
observe the local information.
i For short charge times (charging with 16
A),
connect the fast-charging cable to a wallbox
or charging station without a preinstalled
cable. You can also use the optionally availa-
ble charging cable with the CE plug.

!
If the charge current is too high, the fuse
could be tripped or the external mains supply could overheat. Check if the external mains
supply is equipped to handle the programmed charge current. If necessary, reduce the pro-
grammed charge current or use a different
mains socket.
Before starting the charging process at a power
socket, check the maximum permissible charge current for the relevant power socket or the
building.
You can set the maximum permissible charge
current
R on the charging cable controls (only charging
cable variant 1)
R in the Settings Settings menu of the on-board com-
puter (Y page 292).
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if:
R it is not possible to set the charge current on
the charging cable
R the precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter.
Setting the maximum permitted charge current on the charging cable of variant 1 is described
below.
X To adjust the setting: press button?
repeatedly until the desired setting is selec-
ted in display =.

If, after the charging process, the charging cable is:
R left connected to the power socket, the cur-
rently selected values will be used for the next
charging process.
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.
