Important safety notes

DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the 182
Charging the high-voltage batteryDriving and parking
Heat generated by the charging cable
and charging cable connector Observe the "Important safety notes"
(Y
page 182).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and the charging cable con- nector will only heat up within the permissible
limiting values, provided that:
R the mains 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
If the charging cable or charging cable connec-
tor become too hot, have the mains power sup- ply checked.
Protection 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 or tripping of the
building's fuse, it may take up to 10 minutes
for charging to resume automatically.
Reset the building's circuit breaker. Otherwise,
the charging process cannot be continued.
General information on the charging
process Observe the "Important safety notes"
(Y page 182).
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. Charging the high-voltage battery via
the mains socket
Charging cable for mains sockets 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, variant 1 or variant 2, for con-
nection to a mains socket. The controls of the
two charging cable variants are different. Only
use the charging cable supplied with the vehicle
or a charging cable approved for the vehicle.
i The charging process can vary depending on
the mains power supply. Therefore, always
observe the local information.
i For short charge times (charging with 16
A),
connect the fast-charging cable to a wallbox
or charging station without a preinstalled
cable. You can also use the optionally availa-
ble charging cable with the CE plug.
Information about charging from a wallbox
(Y page 188).
Information about charging from a charging sta-
tion (Y page 189).
Stowing the charging cable The charging cable can be stowed and secured
in the bag provided in the luggage compartment
of the vehicle.

!
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.

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
