charge of the high-voltage battery must be
higher than the specified minimum condition of charge.
The running time of the climate control may
be reduced if:
R the vehicle is not connected to an electric
power supply
R the high-voltage battery is not fully charged
With active "Pre-entry climate control at
departure time" the condition of charge of the
high-voltage battery can be reduced, even if
the charge cable connector is connected.
In certain situations, the desired interior tem-
perature cannot be reached.
When the vehicle is cooled, the following
functions are activated as necessary:

(Y page 195).
Activating immediate pre-entry climate
control You can activate "Immediate pre-entry cli-
mate control" even if the vehicle interior is
already at the desired temperature. This
means that the vehicle interior continues to
be cooled or heated, e.g. if the journey is
interrupted for up to 50 minutes, and the inte-
rior temperature is kept constant. You can
only set the desired temperature using the
climate control unit. If you do not pre-select a temperature, the last temperature set will be
automatically adopted. Operating the climate control systems

To avoid hazardous situations, observe the
following:
R Only connect the charging cable to mains
sockets that:
- are installed correctly and
- have been approved by an electrical spe-
cialist.
R For safety reasons, only use the charging
cables supplied with the vehicle, or charg-
ing cables which have been approved for
use with this vehicle.
R Never use a damaged charging cable.
R Do not use:
- Extension cables
- Cable drums
- Multiple sockets
R Do not use a socket adapter to connect the
charging cable to the mains socket. The
only exception is if the adapter has been
tested and approved by the manufacturer
for charging the high-voltage battery in an
electric vehicle.
R Always observe the safety notes in the
socket adapter's operating instructions.
The vehicle's high voltage electrical system is under high voltage.
R Do not handle high-voltage components or
the orange cables of the vehicle's high-volt-age electrical system.
R Do not touch high-voltage components or
the orange cables of the high-voltage elec-
trical system when a vehicle has been
involved in a crash.
R Do not touch any damaged components or
damaged orange cables of the vehicle's
high-voltage electrical system.
R Do not remove the covers of the high-volt-
age electrical system components that are
marked with a warning sticker. General notes
Method of 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 (except D+), kinetic energy
is converted by means of energy recuperation
into electrical energy and stored in the high-
voltage battery.
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R with the charging cable at a mains socket
while the vehicle is stationary
R with the charging cable at a charging sta-
tion while the vehicle is stationary
The high-voltage battery can be charged in a
voltage range from 110 V to 240 V.
If the condition of charge drops to less than
13%, the high-voltage battery reserve indica-
tor lamp lights up in the instrument cluster.
Charge the high-voltage battery as soon as
possible.
Below a condition of charge of 5%, the per-
formance of the vehicle is reduced. The vehi-
cle's high-voltage electrical system switches
off at a condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not fully charged.
Discharged battery The vehicle's high-voltage electrical system
switches off if the high-voltage battery is com-
pletely discharged. 30 seconds prior to this,
you are informed of the switch-off by the
Battery level too low. Stop and Battery level too low. Stop and High-voltage battery

Calling up functions in the "My
Mercedes Electric - Vehicle Homepage"
The "My Mercedes Electric - Vehicle Home-
page" allows you access to information about your vehicle and its functions using remote
query and remote configuration. For example,
climate control can be activated using remote
configuration which means that it need not be set in the vehicle. Power for the climate con-
trol is primarily supplied via the charging
cable connected to the mains supply. In this
way, the range of the vehicle in most cases is not reduced. If climate control is activated,
the battery charge level and thus the range
may be reduced. The "Vehicle Homepage"
provides you with information all about how
to use your vehicle.
If the vehicle is entered in your personal area of the "Vehicle Homepage", you can also
access the following functions:
R request the current condition of charge of
the high-voltage battery
R program the departure time (Y page 195)
R order and activate the "Pre-entry climate
control at departure time" function
If the vehicle is charging, the predicted charg-
ing time and the predicted range will also be
shown.
This data is estimated and may be influenced
by the following factors:
R outside temperature
R switched on consumers, e.g. climate con-
trol and seat heating
R personal driving style
R road and traffic conditions
R route characteristics
Therefore, allow for a sufficient reserve.
i Information on additional functions and
operating instructions can be found on the "Vehicle Homepage". Connecting the vehicle to the Internet Via a radio module
This function is not available in all countries
and requires an activated mbrace access.
You can use the "Vehicle Homepage" if the
vehicle has a connection to the Internet via a mobile phone. The radio module uses a
mobile phone connection and transmits the
necessary data by radio. The vehicle auto-
matically recognizes whether a connection tothe Internet via the radio module is possible
or not. No presets are necessary.
To enable the transfer of data via the mobile
communications module, you do not need a
SIM card.
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. Parking
