defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.

defroster can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i You can move the adjusters for the air
vents vertically or horizontally to set the

DrivingDriving and parking

To avoid hazardous situations, observe the
following:
R Only connect the charging cable to mains
sockets that:
- are installed correctly and
- have been approved by an electrical spe-
cialist.
R For safety reasons, only use the charging
cables supplied with the vehicle, or charg-
ing cables which have been approved for
use with this vehicle.
R Never use a damaged charging cable.
R Do not use:
- Extension cables
- Cable drums
- Multiple sockets
R Do not use a socket adapter to connect the
charging cable to the mains socket. The
only exception is if the adapter has been
tested and approved by the manufacturer
for charging the high-voltage battery in an
electric vehicle.
R Always observe the safety notes in the
socket adapter's operating instructions.
The vehicle's high voltage electrical system is under high voltage.
R Do not handle high-voltage components or
the orange cables of the vehicle's high-volt-age electrical system.
R Do not touch high-voltage components or
the orange cables of the high-voltage elec-
trical system when a vehicle has been
involved in a crash.
R Do not touch any damaged components or
damaged orange cables of the vehicle's
high-voltage electrical system.
R Do not remove the covers of the high-volt-
age electrical system components that are
marked with a warning sticker. General notes
Method of operation The vehicle is equipped with a high-voltage
battery for driving. The high-voltage battery
stores the energy needed to operate the elec-
tric motor and releases it again.
The electric motor uses energy that has been stored in the high-voltage battery when pull-
ing away, accelerating and during the jour-
ney.
In overrun mode (except D+), kinetic energy
is converted by means of energy recuperation
into electrical energy and stored in the high-
voltage battery.
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R with the charging cable at a mains socket
while the vehicle is stationary
R with the charging cable at a charging sta-
tion while the vehicle is stationary
The high-voltage battery can be charged in a
voltage range from 110 V to 240 V.
If the condition of charge drops to less than
13%, the high-voltage battery reserve indica-
tor lamp lights up in the instrument cluster.
Charge the high-voltage battery as soon as
possible.
Below a condition of charge of 5%, the per-
formance of the vehicle is reduced. The vehi-
cle's high-voltage electrical system switches
off at a condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not fully charged.
Discharged battery The vehicle's high-voltage electrical system
switches off if the high-voltage battery is com-
pletely discharged. 30 seconds prior to this,
you are informed of the switch-off by the

Notes on battery care Avoid storing or transporting the vehicle in
high temperatures over a long period (e.g.
container transport).
If you park the vehicle and leave it stationary
for longer periods, connect it to a power sup-
ply.
Temperatures below Ò13‡(Ò25 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause
irreversible damage.
Conditions of use Observe the following notes:
R information on exceptions and limitations
in warranty documentation and in the rela-
ted Maintenance Booklet
R maintenance notes for the high-voltage
battery in the Maintenance Booklet Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
(Y page 146) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and mal-
functions when charging the vehicle.
To ensure that the brackets within the charg- ing cable controls are not subjected to incor-
rect loads, observe the following:
R Never lift or carry the controls by the charg-
ing cable connector or the mains plug.
R To transport the charging cable, the coiled
part can be:
- wrapped around the controls or
- secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Pay attention to the "Important safety notes"
(Y page 140).
During the charging process, the charging
cable and charging cable connector may heat
up.
The charging cable and charging cable con-
nector will only heat up within the permissible
limiting values, provided that:
R the 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
Should the permissible heating temperature
limits be exceeded, have the mains power
supply checked.
Protection device against overvoltage !
Voltage surges in the mains supply can
damage the vehicle. The vehicle is there-
fore equipped with a device which protects
it from voltage surges in the mains supply.
This device may be triggered during severe
thunderstorms, for example, and may lead
to the building's fuse being tripped and an High-voltage battery

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 electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
! An excessive charge current can blow a
fuse or lead to overheating of the external
power supply. Check whether the external
power supply is compatible with the set charge current. If necessary, lower the set
charge current or use another power
socket.
You can set a limit for the values of the charge current used in charging the high-voltage bat-
tery. This acts as a means of preventing the
power supply from overloading. You can set
this limit by using the controls on the charging
cable or in the on-board computer's menu.
Only set the maximum charge current in the
on-board computer menu if there are no
charge current settings on the charging
cable.
The default standard value is the minimum
charge current setting. This corresponds to
the minimum available charge current from
the power supply.
i The value of the maximum setting and the
relevant adjustment values may vary
depending on the country.
Before charging the high-voltage battery,
have the maximum permissible charge cur-
rent for the relevant power socket checked by
an electrician.
X To adjust the setting: press button?

If, after the charging process, the charging
cable is:
R left connected to the power socket, the
currently 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 current.
