Observe the provider's instructions at the
charging station.
Charging station with charging commu-
nication („Plug&Charge“) You do not have to activate charging sta-
tions with charging communication before
the charging process. This is done by the
vehicle. This function is called "Plug &
Charge". Information is exchanged
between the vehicle and the charging sta-
tion via the charging cable for activation.
This is for:
R mutual authorization of the vehicle and
the charging station
R verification of contract data
R automatic billing of the energy costs
Electronic certificates are used here for
secure exchange of data.
If the verification of contract data is suc-
cessful, the charging process is initiated.
i A preliminary version of the
ISO/IEC 15118 standard is used for com-
munication between the vehicle and the
charging station. If it is necessary to
update your vehicle, consult an author-
ized electric drive smart center.
In order to use "Plug & Charge", you have to
configure the functions of your vehicle on
the "Vehicle Homepage" (Y page 120). For
this you require a "Plug & Charge" certif-
icate which you receive from your power
company after concluding a suitable con-
tract. Consult an authorized electric drive
smart center if you have problems with the
configuration or have no access to the
Internet.
The charging station offers information on the availability of electricity and costs.
This information is processed by the vehi-
cle and is used for an optimum charging of the high‑voltage battery (Y page 123). The
energy costs are automatically calculated
after the charging process is complete. With your existing electricity contract,
you and others who have access to your vehi-
cle can charge the costs to your electricity
bill. For this reason, cancel your existing electricity contract for this vehicle
before you sell it. Delete your "Plug &
Charge" certificate by all means.
i You can delete the certificate from the
vehicle's data on the "Vehicle Home-
page". Please consult an authorized
electric drive smart center if you do not have access to the Internet.
If the charging station allows the connec-
ted vehicle access to the Internet, you can
call up and change information pertaining to the vehicle on the "Vehicle Homepage"

Connecting the vehicle to the Internet Via mobile service module
i This function is only available if the
vehicle is equipped with a mobile ser-
vice module.
You can use the “Vehicle Homepage” when
the vehicle has connected to the Internet
via the mobile service module. The mobile
service module uses GSM (Global System for Mobile Communications) and transfers the
required data via radio transmission. The
vehicle automatically detects if a connec- tion to the Internet via the mobile service module is available or not. No pre-settings
need to be done.
In order to use data transfer via the mobile
service module you do not need a SIM card
and no contract.
i There may be service limitations if the
vehicle is located for example in a
underground garage. Service limita-
tions may also appear in areas with poor
mobile service coverage. In theses cases
you can launch the Internet connection
via powerline (Y page 122).
Via powerline
You can also access the “Vehicle Homepage”
if you do not have GSM reception. This is
possible for example via your DSL router.
This connection is built by the plugged in charging cable with the aid of the power-
line technology.
The vehicle supports powerline communi-
cation according to the "HomePlug AV" standard. Data is transmitted via phase L1
and the neutral conductor of the power line.
In order for the vehicle to access the Inter-net, you require a commercially available
adapter of the "HomePlug AV" standard.
This adapter must also have an encryption
button so that it can be configured to com-
municate with the vehicle. Connect the
adapter to the power supply as well as your Internet connection. If the adapter is con-
nected to different phase than L1, a phase
coupler must be additionally installed.
Only in this way can stable communication
be guaranteed. For questions, consult a
qualified electrician.
i If you already have a powerline network
installed, the vehicle can be integrated
into it.
To establish a connection between the
vehicle and a powerline adapter, carry out
the following:
X Connect the vehicle to a power socket or a
wallbox.
The right #indicator lamp on the
vehicle socket must flash green.
X Insert the powerline adapter into a
neighboring power socket. Observe that
the vehicle and the adapter are connec-
ted via phase L1.
X Switch on the ignition.
X Call up the Charge current
Charge current menu on the
control system (Y page 92).
Carry out the following steps within
30 seconds: X If the value of the charge current is not
set to 8 A:set the value to 8 A and confirm.
X Set the value of the charge current to 12 A
and confirm.
X Set the value of the charge current to 8 A
and confirm. 122
