2015 MERCEDES-BENZ S-Class charging

The charging cable and connector will only
heat up within the permissible limiting values,
provided that:
R the power supply and the charging cable
are not damaged
R the instructions for handling the charging
cable and controls on the charging cable
are observed
If the charging cable or plug get too hot, have the mains power supply checked.
Protection device against overvoltage !
Overvoltage in the mains supply may
damage the vehicle. For this reason, the
vehicle is equipped with a protection device
against overvoltage in the mains supply.
This device may be triggered during severe thunderstorms, for example, and may lead
to the building's fuse being tripped and an
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 or tripping of the building's fuse, it may take up to 10 minutes for charging to
resume automatically.
Switch on the building's fuse again after it has
been triggered. Otherwise, the charging proc-
ess cannot be continued.
General information about the charging
procedure Pay attention to the important safety notes
(Y
page 209).
If you unlock/lock the vehicle from the out-
side, the charge socket flap also unlocks/
locks.
The charge socket flap is behind the bumper
on the right-hand side below the rear lamp
cluster. Charging the high-voltage battery via

Charging cable for mains sockets 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.
A charging cable for connection to the mains
socket is included with the vehicle. Only use
the charging cable included with the vehicle
or charging cables that have been approved
for the vehicle.
i If you use the supplied 12 A charging
cable to charge a high-voltage battery:
R the charge time increases considerably
R electrical consumption increases consid-
erably
Where possible, charge the high-voltage
battery at a charging station (Y page 216).
Only then can certified electrical energy
consumption levels be reached.
i The charging process can vary depending
on the power supply. Therefore, always
observe the local information.
i For short charge times (charging with
16A), connect the fast-charging cable to
the wallbox/charging station. You can also
use the optionally available charging cable
with the CE plug.
Information about charging from a wallbox
can be found at (Y page 215).
Information about charging at a charging sta-
tion can be found at (Y page 216).
Stowing the charging cable
The charging cable can be stowed in the bag
supplied in the trunk of the vehicle and held in place with the Velcro fastener. 212

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, checkthe 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 in the vehicle cor- responds to the maximum charge current
value.
The default standard value on the charging
cable is the minimum charge current setting.This corresponds to the minimum available
charge current from the power supply. The
value on the charging cable can be increased
and is described in the following section.
i The value of the maximum setting and the
adjustment values may vary depending on
the country. Charging the high-voltage battery (plug-in hybrid vehicles)

Before charging the high-voltage battery,
check the maximum permissible charge cur-
rent for the relevant power socket.
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
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.
i If the vehicle requires more time than
usual when charging, check the maximum
charge current settings using the controls
on the charging cable or in the on-board
computer's menu.
