Shifting gears !
Mercedes-AMG vehicles:
the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim- iting speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the rev counter. There is
otherwise a risk of engine damage. X
To shift up: pull steering wheel gearshift pad-
dle ;.
The automatic transmission shifts up to the
next gear.
All vehicles (except Mercedes-AMG vehi-
cles): if the maximum engine speed on the
currently engaged gear is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up in order to
prevent engine damage.
X To shift down: pull steering wheel gearshift
paddle :.
The automatic transmission shifts down to
the next gear.
Automatic downshifting occurs when coast-
ing.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine damage
by not shifting down. Automatic transmission

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 mains supply may overheat. There isa risk of fire.
Before charging, check the maximum permis-
sible charge current available at the location.
If necessary, contact a qualified specialist
company for assistance.
Adjust your vehicle's settings, if necessary. 186
Charging the high-voltage batteryDriving and parking

!
If the charge current is too high, the fuse
could be tripped or the external mains supply could overheat. Check if the external mains
supply is equipped to handle the programmed charge current. If necessary, reduce the pro-
grammed charge current or use a different
mains socket.
Before starting the charging process at a power
socket, check the maximum permissible charge current for the relevant power socket or the
building.
You can set the maximum permissible charge
current
R on the charging cable controls (only charging
cable variant 1)
R in the Settings Settings menu of the on-board com-
puter (Y page 292).
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if:
R it is not possible to set the charge current on
the charging cable
R the precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter.
Setting the maximum permitted charge current on the charging cable of variant 1 is described
below.
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 cur-
rently 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 cur-
rent.
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.

General notes It is recommended that you charge your vehicle
using a wallbox or at a charging station.
Use the optionally available fast-charging cable
when charging your vehicle from a wallbox with- out a preinstalled cable. The charging cable is
stored in a bag in the 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.
Make sure that the maximum charging current is
not limited in the Settings Settingsmenu of the on-
board computer. You must select the maximum 188

Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. !
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand the
key must be removed from the ignition lock
R the front wheels must be turned towards the
kerb on steep uphill or downhill gradients
R the empty vehicle must be secured at the
front axle with a wheel chock or similar
object, for example, on uphill or downhill gra-
dients
R a laden vehicle must also be secured at the
rear axle with a wheel chock or similar object,
for example, on uphill or downhill gradients Switching off the engine
