=Leaving the vehicle idle for lengthy periods
at high ambient temperaturesTo avoid accelerated aging, please
observe the following recommendations
when handling the high-voltage battery.
Recommendations when handling the high-voltage
battery:
= Every six months, when the outside tempera-
ture is above 50 °F (10 °C), park the vehicle overnight with a charge level below 20%.
= Only charge the high-voltage battery with
direct current (mode 4) if necessary.
= Charge the high-voltage battery on average to
a charge level of 80%. Beyond a charge level of
80%, the charging time is considerably pro-
longed.
= If leaving the vehicle idle for lengthy periods,
park up the vehicle with a high-voltage battery
charge level between 30% and 50%. Do not keep the high-voltage battery continuouslyconnected to power supply equipment.
= If leaving the vehicle idle for lengthy periods of
time avoid, if possible, high ambient tempera-
tures.
= Check the high-voltage battery\bs charge level
every six weeks (  page 202).
= Charge the high-voltage battery if the charge
level is below 20%.
= Do not disconnect the 12 V battery even if the
vehicle is les idle for a lengthy period. Other-
wise, the condition of the vehicle\bs high-volt-
age battery cannot be monitored.
You can contribute to reducing the vehicle\bs
energy consumption in the following ways:
= An anticipatory driving style (  page 179)
= Reduced use of electrical consumers
= Having the vehicle regularly maintained
The charging time of the high-voltage battery may
change over the course of its life.
You can charge the high-voltage battery with both alternating current (mode 2 or 3) and direct cur-
rent (mode 4).1Socket for charging with alternating current2Socket extension for charging with direct cur-
rent\bWhen using a CCS (Combined Charging Sys- tem) charging cable to charge with direct cur-
rent, both areas of the vehicle socket are cov-
ered by the charging cable connector.Driving and parking189

Charging options for the high-voltage battery
(mode 2, 3 or 4):
= Charging through recuperation while the vehi-
cle is in motion
= Charging with alternating current when sta-
tionary:
- at a mains socket (mode 2)
- at a wallbox or charging station (mode 3)
= Charging with direct current when stationary:
- at a rapid charging station (mode 4)
Depending on the country-speciNc vehicle equip-
ment and your vehicle\bs charging cable, single
phase AC charging is also possible.
Observe the diMerent grid requirements of your
current location when charging. Only use charging
cables which conform to the grid requirements.
Consult a qualiNed electrician or your local grid
operator if you have any questions.
It is recommended that you charge the high-volt-
age battery at a wallbox or charging station due to
the improved charging performance and better
charging ePciency oMered.Stowing the charging cable
Always stow the vehicle charging cable in the charging cable bag provided and attach its spring
hook to the cargo tie-down rings in the trunk or the cargo compartment.
Otherwise, the charging cable is not suPciently
secured.
System limits
The power output of the high-voltage battery may be impaired by the following:
= High or low outside temperatures
= Electrical auxiliary consumers in the vehicle
being switched on, e.g. operating the air con- ditioning system
= Extended periods without charging
The charging time of the high-voltage battery may
be increased by the following:
= High or low outside temperatures
= Extended periods without charging
= The maximum available charge current of the
charging facility= The settings of the charging process in the
multimedia system (  page 203)
Notes on charging the high-voltage battery at the
mains socket (mode 2)
&DANGER Risk of fatal injury from incor-
rectly installed component parts
Connecting the charging cable to a mains
socket using incorrectly installed component
parts could cause a Nre or an electric shock,
for example.
Only connect the charging cable to a mains socket that:
= Has been properly installed and
= Has been inspected by a qualiNed electri-
cian
For safety reasons, only use the charging
cable supplied with the vehicle or an
original Mercedes-Benz charging cable.190Driving and parking

Purchase these parts at an authorized
Mercedes-Benz Center and obtain advice
there.
Mercedes-Benz thoroughly tests these original
charging cables for their suitability for high-
voltage charging of your vehicle.
Never use a damaged charging cable.Do not use:
= Extension cables
= Extension reels
= Multiple sockets
Never use socket adapters to connect
the charging cable to the mains socket.
The only exception being if the adapter
has been tested and approved by the
manufacturer for charging the high-volt-
age battery of an electric vehicle.Observe the safety notes in the operat- ing instructions for the socket adapter.
Only the following charging cables may be used:
= The charging cable supplied with the vehicle.
=A charging cable that has been approved for
the vehicle.
The charging process can vary depending on the power supply equipment. The charging timeswhen 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 lis the controls by the following compo-
nent parts:
= the charging cable connector
= the mains plug
When charging, protect the charging cable control element from excessive heat such as direct sun-
light. Otherwise, the charging process may be canceled.Notes on charging the high-voltage battery at a
wallbox or charging station (mode 3)&DANGER Risk of fatal injury from incor-
rectly installed component parts
Connecting the charging cable to the vehicle
using incorrectly installed components could
cause a Nre or an electric shock, for example.
Only connect the charging cable to a
wallbox if:
= The wallbox has been properly installed
= The wallbox has been inspected by a quali-
Ned electrician
= The charging cable is not damaged
Do not extend the charging cable.Do not use adapters.Observe the safety notes in the operat-
ing instructions for the wallbox.Driving and parking191

&DANGER Risk of fatal injuries due to dam-
aged components
Connecting the charging cable to a charging
station using a damaged component part
could cause a Nre or an electric shock, for
example.
For charging stations with a preinstalled
charging cable: = Perform a visual check of the charg-
ing station for obvious malfunctions,
such as massive damage to the hous-
ing or charging cable.For charging stations without a preinstal-
led charging cable:
= For safety reasons, only use charging
cables that have been tested and
approved by the manufacturer for
charging the high-voltage battery in
an electric vehicle.
= Never use damaged charging cables.
= Do not extend the charging cable.
= Do not use adapters.Make sure to observe the safety informa-
tion on the charging station.
Most charging stations must be activated before
the charging process, e.g. using an RFID card or
via Plug & Charge. Observe the on-site operator\bs
instructions for the charging station and the notes
on Mercedes me Charge (see the vehicle\bs Digital
Operator\bs Manual).
The amount of energy dispensed for the charging
process, shown by the charging station, may be higher than the amount of energy actually absor-
bed by the high-voltage battery. This is the result
of diMerent levels of charging losses and is descri-
bed as recharge ePciency. Charging losses occur,
for example, due to heat that builds up when the vehicle is charging or from auxiliary consumersthat are switched on. Further information onrecharge ePciency can be obtained at a qualiNed
specialist workshop.

=Do not use adapters.Make sure to observe the safety informa-
tion on the charging station.&DANGER Risk of fatal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-board electrical system is under high volt-
age.
Do not perform any maintenance work
during the charging process.
Most charging stations must be activated prior to the charging process, e.g. using an RFID card or
via Plug-and-Charge. Observe the on-site opera-
tor\bs instructions for the charging station and the notes on Mercedes me Charge (see the vehicle\bs
Digital Operator\bs Manual).
The amount of energy dispensed for the charging
process, which is shown by the charging station,
may be higher than the amount of energy actually
absorbed by the high-voltage battery. This is the
result of diMerent levels of charging losses and is
described as recharge ePciency. Charging losses
occur, for example, due to heat that builds up
when the vehicle is charging or from auxiliary con-
sumers that are switched on. Further information
on recharge ePciency can be obtained at a quali-
Ned specialist workshop.
Maximum permissible charging current for charg-
ing at a mains socket
*NOTE Overloading the mains socket due
to excessive charging current
If the charging current is too high, the fuse
could be tripped or the external mains supply
could overheat.
Ensure that the external mains supply
has been designed to handle the charg-
ing current provided.For safety reasons, only use the charging
cable supplied with the vehicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables for their suitabil-ity for high-voltage charging of your vehi-
cle.Purchase these parts at a Mercedes-
Benz service center and obtain advice
there.Check the maximum charging current
using the charging capacity shown on
the driver\bs display.
The charging cable supplied is set to a country-
speciNc maximum charging current value. When
charging abroad, the maximum value may exceed the permitted value for that country.
Before charging at a mains socket, have the
maximum permissible charging current for the
relevant mains socket or the building checked
by a qualiNed electrician.When abroad, observe the country-speciNc
laws when charging.
If you have questions concerning the charging
current or if there is a malfunction, please contact
a qualiNed specialist workshop.
