Method of operation The vehicle is equipped with a high-voltage
battery for driving. The high-voltage battery
stores the energy needed to operate the elec-
tric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pull-
ing away, accelerating and during the jour-
ney. 210
Cha
rging the high-voltage battery (plug-in hybrid vehi cles)Driving and parking

In overrun mode, kinetic energy is converted
by means of energy recuperation into electri- cal energy and stored in the high-voltage bat-
tery.
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R during the journey using the CHARGE mode
R with the relevant charging cable at an elec-
trical outlet while the vehicle is stationary
R with the relevant charging cable at a wall-
box while the vehicle is stationary
R with the relevant charging cable at a charg-
ing station while the vehicle is stationary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
High and low outside temperatures Low outside temperatures
At very low outside temperatures the maxi-
mum 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 bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age 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 the use of air conditioning or heating
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 in
temperatures that are too high or too low over
a long period (e.g. container transport).
If you park the vehicle and leave it stationaryfor longer periods, connect it to a power sup-
ply.
Conditions 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 Do not leave the charging cable controls
(Y
page 213) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and mal-
functions when charging the vehicle.
To ensure that the cable on the controls of the charging cable is not subjected to incorrect
loads, observe the following:
R Never lift the controls up at the charging
cable connector or the power supply plug.
R Do not carry the controls by the connector.
Heat generated by the charging cable
and connector Pay attention to the "Important safety notes"
(Y page 209).
During the charging process, the charging
cable and connector may heat up. Charging the high-voltage battery (plug-in hybrid vehicles)
211Driving and parking Z

The charging cable and connector 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 plug get too hot, have the mains power supply checked.
Protection device against overvoltage !
Overvoltage in the mains supply may
damage 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 thunderstorms, for example, and may lead
to the building'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 automatically.
Following an interruption in the power sup-
ply or tripping of the building's fuse, it may take up to 10 minutes for charging to
resume automatically.
Switch on the building's fuse again after it has
been triggered. Otherwise, the charging proc-
ess cannot be continued.
General information about the charging
procedure Pay attention to the important safety notes
(Y
page 209).
If you unlock/lock the vehicle from the out-
side, the charge socket flap also unlocks/
locks.
The charge socket flap is behind the bumper
on the right-hand side below the rear lamp
cluster. 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 charg-
ing cable for other purposes. It may other-
wise be damaged.
A charging cable for connection to the mains
socket is included with the vehicle. Only use
the charging cable included with the vehicle
or charging cables that have been approved
for the vehicle.
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 consid-
erably
Where possible, charge the high-voltage
battery at a charging station (Y page 216).
Only then can certified electrical energy
consumption levels be reached.
i The charging process can vary depending
on the power supply. Therefore, always
observe the local information.
i For short charge times (charging with
16A), connect the fast-charging cable to
the wallbox/charging station. You can also
use the optionally available charging cable
with the CE plug.
Information about charging from a wallbox
can be found at (Y page 215).
Information about charging at a charging sta-
tion can be found at (Y page 216).
Stowing the charging cable
The charging cable can be stowed in the bag
supplied in the trunk of the vehicle and held in place with the Velcro fastener. 212

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, checkthe 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 current. If necessary, lower the set
charge current 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 in the vehicle cor- responds to the maximum charge current
value.
The default standard value on the charging
cable is the minimum charge current setting.This corresponds to the minimum available
charge current from the power supply. The
value on the charging cable can be increased
and is described in the following section.
i The value of the maximum setting and the
adjustment values may vary depending on
the country. Charging the high-voltage battery (plug-in hybrid vehicles)
