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.
Following an accident, do not touch any high- voltage components and never modify the vehicle'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 can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. Charging the high-voltage battery (plug-in hybrid vehicles)
209Driving and parking Z

In overrun mode, kinetic energy is converted
by means of energy recuperation into electri- cal energy and stored in the high-voltage bat-
tery.
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R during the journey using the CHARGE mode
R with the relevant charging cable at an elec-
trical outlet 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.
High and low outside temperatures Low outside temperatures
At very low outside temperatures the maxi-
mum 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 bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age 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 the use of air conditioning or heating
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 in
temperatures that are too high or too low over
a long period (e.g. container transport).
If you park the vehicle and leave it stationaryfor longer periods, connect it to a power sup-
ply.
Conditions 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 213) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and mal-
functions when charging the vehicle.
To ensure that the cable on the controls of the charging cable is not subjected to incorrect
loads, observe the following:
R Never lift the controls up at the charging
cable connector or the power supply plug.
R Do not carry the controls by the connector.
Heat generated by the charging cable
and connector Pay attention to the "Important safety notes"
(Y page 209).
During the charging process, the charging
cable and connector may heat up. Charging the high-voltage battery (plug-in hybrid vehicles)

cle Homepage".
Connecting the vehicle to the Internet i
This function is not available in all coun-
tries and requires activated access to the
mbrace emergency call system.
i This function is only available if the vehi-
cle is equipped with a telephone module.
You can use the "Vehicle Homepage" if the
vehicle has a connection to the Internet via
the telephone module. The telephone module uses CDMA (Code Division Multiple Access)
and transmits the necessary data by radio.
The vehicle automatically recognizes whether a connection to the Internet via the telephone
module is possible or not. No presets are
necessary. i
Restrictions in reception are possible if
the vehicle is in an underground car park,
for example. Restrictions may also occur in areas with poor mobile network coverage.
To enable the transfer of data via the tele-
phone module, you do not need a SIM card. Parking
