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 (
Ypage 232).
The high-voltage battery can be charged as fol-
lows:
Rthrough energy recuperation while the vehicle
is in motion
Rthrough the combustion engine while driving
in CHARGE operating mode (Ypage 226)
Rwith the relevant charging cable at an electri-
cal outlet while the vehicle is stationary
Rwith the relevant charging cable at a wallbox
while the vehicle is stationary
Rwith the relevant charging cable at a charging station while the vehicle is stationary
Charging the high-voltage battery (PLUG-IN HYBRID vehicles)169
Driving an d parking
Z

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. Youcan find information in "PLUG-IN HYBRID oper-
ation", section "Menus and submenus" under
"Energy flow display" (
Ypage 227).
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:
Rhigh and low outside temperatures
Roperating the climate control system
Rswitching 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:
Ra reduction in battery performance
Rlonger 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:
Rcheck the condition of charge of the high-
voltage battery more often
Rconnect 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
Do not leave the charging cable controls
(Ypage 171) 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.
To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
RNever lift or carry the controls by the charging
cable connector or the mains plug.
RTo transport the charging cable, the coiled
part 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"
(Ypage 168).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting values, provided that:
Rthe power supply and the charging cable are
not damaged
Rthe 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 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
170Charging the high-voltage battery (PLUG-IN HYBRID vehicles)

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"
(Ypage 168).
