energy and stored in the high-voltage battery.
Information on overrun mode (Ypage 253).
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 246)
Rwith the relevant charging cable at an electri-
cal outlet while the vehicle is stationary
Rat a wallbox while the vehicle is stationary
Rat 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" (
Ypage 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:
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
