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 253).
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 243)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. You
can find information in "PLUG-IN HYBRID oper-
ation", section "Menus and submenus" under
"Energy flow display" ( Y
page 245).Charging the high-voltage battery (PLUG-IN HYBRID vehicles) 181
Driving and parking Z

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.

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.182
