If the charging cable or charging cable connec-
tor become too hot, have the mains power sup-
ply checked.
Protection device against overvoltage
! Overvoltage in the mains supply may dam-
age 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 thunder-
storms, for example, and may lead to the buil-
ding'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 auto-
matically. Following an interruption in the
power supply or tripping of the building's fuse,
it may take up to 10 minutes for charging to
resume automatically.
Switch on the building protection system again
after it has been triggered. Otherwise, the
charging process cannot be continued.
General information about the charging
procedure Pay attention to the "Important safety notes"
( Y
page 169).
The vehicle socket is located in the rear bumper
on the right below the tail lamp.
The charge socket flap and the vehicle are cen-
trally locked or unlocked simultaneously.

the electrical outlet
Charging cable for electrical outlets
Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be
damaged.
The vehicle is supplied with a country-specific
charging cable for connection to a mains socket.
Only use the charging cable supplied with the
vehicle or a charging cable 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 consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station ( Y
page 175). Only
then can certified electrical energy consump-
tion levels be reached.
i The charging process can vary depending on
the power supply. Therefore, always observe
the local information.

Stowing the charging cable The charging cable can be stowed and secured
in the bag provided in the cargo compartment of
the vehicle.

Fuses
Important safety notes
G WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
! For the fuse boxes in the engine compart-
ment and under the rear bench seat, only use
fuses with the suffix "S". Otherwise, compo-
nents or systems could be damaged.
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 located in the fuse
box under the rear bench seat ( Y
page 385).
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 Observe the important safety notes

The fuses are located in various fuse boxes: R
Fuse box on the front-passenger side of the
dashboard R
Fuse box in the engine compartment on the
right-hand side of the vehicle, when viewed in
the direction of travel R
Fuse box under the rear bench seat
Dashboard fuse box Pay attention to the important safety notes
( Y
page 384).
! Do not use a pointed object such as a screw-
driver to open the cover in the dashboard. You
could damage the dashboard or the cover.
! 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.
