Influences on the charging behavior
and the charge state of the high-volt-
age battery
Terms of use Observe the following notes:
R information on exceptions and limitations in
warranty documentation and in the related
Maintenance Booklet
R maintenance notes for the high-voltage bat-
tery in the Maintenance Booklet
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
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 fol-
lows:
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 station
while the vehicle is stationary
The high-voltage battery can be charged using a
single-phase charging cable in a voltage range
from 100 V to 240 V.
If the condition of charge drops to less than 13%, the high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a condition of charge of 5%, the perform-
ance of the vehicle is reduced. The vehicle'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. High and low outside temperatures Low outside temperatures
The efficiency of the high-voltage battery is sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer able to provide the normal electrical power out-
put.
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 automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 152).
Notes on battery care Avoid storing or transporting the vehicle in high
temperatures over a long period (e.g. container
transport).
If you park the vehicle and leave it stationary for
longer periods, connect it to a power supply.
Temperatures below 00F813 ‡ (00F825 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause irre- versible damage.
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

must destroy documents containing the vehi-
cle verification code (VVC).
R If you have bought a used vehicle, it is possi-
ble that the previous owner still has access to
the "Vehicle Homepage". If in doubt, have a
new vehicle verification code (VVC) issued by
the Mercedes-Benz Center after purchase.
With the code you can set up access to your
vehicle, as described in the section "Setting
up a personal area" on the Vehicle Home-
page". There, you may also deactivate the
existing access of the previous owner.
Calling up functions in the "My
Mercedes Electric - Vehicle Homepage" The "My Mercedes Electric - Vehicle Homepage"
allows you access to information about your
vehicle and its functions using remote query and
remote configuration. For example, climate con- trol can be activated using remote configuration
which means that it need not be set in the vehi- cle. Power for the climate control is primarily
supplied via the charging cable connected to the mains supply. In most cases, this does not
reduce the range. If climate control is activated,the condition of charge 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 163)
R order and activate the "Pre-entry climate con-
trol at departure time" function
If the vehicle is charging, the predicted charging
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 control
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 vehi-
cle 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 automatically recognizes
whether a connection to the 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
