Notes on charging the high-voltage battery at the

mains socket (mode 2)

The charging process can vary depending on the

power supply equipment. The charging times

when charging the high-voltage battery at the

mains socket are considerably longer than when

charging at a wallbox or charging station.

When doing so, always observe the local informa-

tion.

Do not leave the charging cable controls hanging

loose from a mains socket.

Do not liꢀ the controls by the following compo-

nent parts:

Mercedes-Benz thoroughly tests these original

charging cables for their suitability for high-

If charging at a wallbox without pre-installed

cable, use the optionally available charging cable

for wallbox and charging station (mode 3). The

charging cable is stowed in a bag in the boot/

luggage compartment.

Only use charging cables that have been tested

and approved by the manufacturer for charging

the high-voltage battery in an electric vehicle.

Connecting the charging cable to a wallbox

using incorrectly installed component parts

could cause a ﬁre or an electric shock, for

example.

Most charging stations must be activated before

the charging process, e.g. using an RFID card or

via Plug-and-Charge. Observe the on-site opera-

tor's instructions for the charging station and the

During the charging process, the high-voltage

on-board electrical system is under high volt-

age.

Connecting the vehicle to a charging station

using damaged component parts could cause

a ﬁre or an electric shock, for example.

Do not perform any maintenance work

during the charging process.

Do not use an extension for the charging

cable.

The charging cable for the vehicle must not be

longer than 30 m due to the legal requirements in

some countries. This is to prevent the interfer-

ence of signals being received by radio communi-

cation devices in the vehicle or in close proximity

to the charging station. Be aware that parts of the

charging cable may be routed underground. If in

doubt, ask the charging station operator if this is

the case before charging the high-voltage battery.
