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 V to 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).
