interruption in the power supply. These
functions protect the vehicle. After the
building fuse is switched on again, the
charging process resumes automatically.
Following an interruption in the power sup- ply without tripping of the building's fuse, it
may take up to 15 minutes for charging to
resume automatically.
Switch on the building's fuse again after the
protection device against overvoltage has
been triggered. Otherwise, the charging proc-
ess cannot be continued. The high-voltage
battery will not be charged and you may not
be able to drive the vehicle.
If other devices are protected by the same
protective device, these are switched off as
well when the protective device is triggered.
Ensure that these other devices are still
operational after reactivating the protection
device. Charging the high-voltage battery via

Charging cable Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charg-
ing cable for other purposes. It may other-
wise be damaged.
The vehicle is supplied with a single-phase
12 A charging cable. Only use the charging
cable included with the vehicle, which has
been approved for vehicle use.
Pay attention to the "Important safety notes"
(Y page 140).
If you use the supplied 12 Acharging cable to
charge a high-voltage battery:
R the charge time increases considerably
R electrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station (Y page 149). Onlythen can certified electrical energy consump-
tion levels be reached.
i The charging process can vary depending
on the charging station. Therefore, always
observe the local information.
Stowing the charging cable
The charging cable can be stowed in a bag in the trunk of the vehicle. To do so, the bag
must be secured to the cargo tie-down rings
using the retaining strap provided.

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 electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
! An excessive charge current can blow a
fuse or lead to overheating of the external
power supply. Check whether the external
power supply is compatible with the set charge current. If necessary, lower the set
charge current or use another power
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
power 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 standard value is the minimum
charge current setting. This corresponds to
the minimum available charge current from
the power supply.
i The value of the maximum setting and the
relevant adjustment values may vary
depending on the country.
Before charging the high-voltage battery,
have the maximum permissible charge cur-
rent for the relevant power socket checked by
an electrician.
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
Information about the charging time
(Y page 334)
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.
If the charge current values that have been
set on the charging cable and the on-board High-voltage batte

computer are different, the high-voltage bat-
tery is charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:

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
