(PLUG-IN HYBRID vehicles) Important safety notes
G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceeda critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
DANGER

Operation The vehicle is equipped with a high-voltage
battery for driving. The high-voltage battery
stores the energy needed to operate the elec-
tric motor and releases it again.
The electric motor uses energy that has been stored in the high-voltage battery when pull- ing away, accelerating and during the jour-
ney.
In overrun mode, kinetic energy is converted
by means of energy recuperation into electri- cal energy and stored in the high-voltage bat-
tery. Information on overrun mode
(Y page 299).
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R during the journey by the combustion
engine in CHARGE operating mode
(Y page 290)
R with the relevant charging cable at a mains
socket while the vehicle is stationary
R with the relevant charging cable at a wall-
box while the vehicle is stationary
R with the relevant charging cable at a charg-
ing 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-
voltage battery in the multifunction display.
You can find information in "PLUG-IN HYBRID
operation", section "Menus and submenus"
under "Energy flow display" (Y page 291).
High and low outside temperatures Low outside temperatures
The maximum performance of the high-volt-
age battery is significantly reduced at very
low outside temperatures. 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 bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age battery is reduced by the vehicle. Charging the high-voltage battery (PLUG-IN HYBRID vehicles)

Setting the maximum charge current G
WARNING
If the charge current draw via a mains socket is too high during the charging process, the
external mains supply may overheat. There is a risk of fire.
Before charging, check the maximum permis-
sible charge current available at the location.
If necessary, contact a qualified specialist
company for assistance.
Adjust your vehicle's settings, if necessary.
! If the charge current is too high, the fuse
could be tripped or the external mains sup-
ply could overheat. Check if the external
mains supply is equipped to handle the pro- grammed charge current. If necessary,
reduce the programmed charge current or
use a different mains socket.
You can set a limit for the values of the charge
current used in charging the high-voltage bat- tery. This acts as a means of preventing the
mains supply from overloading. You can set
this limit by using the controls on the charging
cable or in the on-board computer's menu.
Only set the maximum charge current in the
on-board computer menu if there are no
charge current settings on the charging
cable.
The default value in the vehicle corresponds
to the maximum charge value.
The default value on the charging cable is the
minimum setting. This corresponds to the minimum available charge current from the
mains supply. The value on the charging cable
can be increased and is described below.
i The value of the maximum setting and the
adjustment value may vary depending on
the country.
Before charging the high-voltage battery,
check the maximum permissible charge cur-
rent for the relevant power socket.
X To adjust the setting: press button?
repeatedly until the desired setting is selec- ted in display =.
R Two LEDs are flashing: minimum setting
R All LEDs are flashing: maximum setting
If, after the charging process, the charging
cable is:
R left connected to the power socket, the
currently selected values will be used for
the next charging process.
R removed from the power socket, the values
will be reset to the minimum setting for the next charging process. You may then need
to reset the values of the maximum charge current.
i If the vehicle requires more time than
usual when charging, check the maximum
charge current settings using the controls
on the charging cable or in the on-board
computer's menu.
