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 246)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 247).
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.
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
( Y
page 172) 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: 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: -
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"
( Y
page 169).
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 power supply and the charging cable are
not damaged R
