R
Never use damaged charging cables.
R Do not extend the charging cable.
R Do not use an adapter.
R Always observe the safety notes in the wall-
box'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 electrical
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-voltage
electrical system components that are
marked with a warning sticker. Notes on the charging cable
Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
(Y
page 123) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.
To ensure that the brackets within the charging cable controls are not subjected to incorrect
loads, observe the following:
R Never lift or carry the controls by the charging
cable connector or the mains plug.
R To transport the charging cable, the coiled
part can be:
- wrapped around the controls or
- secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Pay attention to the important safety notes
(Y page 117).
During the charging process, the charging cable
and charging cable connector may heat up. The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting 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
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Electrical fuse against overvoltage !
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
electrical fuse against overvoltage has been
tripped. Otherwise, the charging process 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 pro-
tective 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. 118

wise, components or systems could be dam-
aged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper- ation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of the same rating, which you can recognize by the
color and value. The fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is in the fuse box in the front-passenger footwell (Y page 256).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified special- ist workshop, e.g. an authorized Mercedes-Benz
Center. Before changing a fuse
X Secure the vehicle against rolling away
(Y page 128).
X Switch off all electrical consumers.
X Vehicles without KEYLESS-GO: remove the
SmartKey from the ignition lock.
X Vehicles with KEYLESS-GO: open the driv-
er's door.
The vehicle electronics now have status 0.
This is the same as the SmartKey having been removed.
The fuses are located in various fuse boxes: R Fuse box in the engine compartment on the
left-hand side of the vehicle, when viewed in
the direction of travel
R Fuse box in the front-passenger footwell
