Important safety notes
GDANGER
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.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.

General notes
Method of operation
The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode, kinetic energy is converted by
means of energy recuperation into electrical
energy and stored in the high-voltage battery.
Information on overrun mode (
Ypage 24).
The high-voltage battery can be charged as fol-
lows:
Rthrough energy recuperation while the vehicle is in motion
Rthrough the combustion engine while driving
in CHARGE operating mode (Ypage 21)
Rwith the relevant charging cable at an electri-
cal outlet while the vehicle is stationary
Rat a wallbox while the vehicle is stationary
Rat a charging station while the vehicle is sta-
tionary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
You can view the condition of charge of the high-
voltage battery in the multifunction display.
Information about this can be found under
"Energy flow display" (
Ypage 40).
High and low outside temperatures
Low outside temperatures
At very low outside temperatures the maximum
power output of the high-voltage battery may be
reduced. The high-voltage battery is then no
longer able to provide the normal electrical
power output.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced by the vehicle.
Energy consumption and electrical
range
The maximum electrical range is generally
reduced by:
Rhigh and low outside temperatures
Roperating the climate control system
Rswitching on consumers
The battery's physical characteristics are such
that leaving the vehicle parked for long periods
at low outdoor temperatures without charging it
can lead to:
Ra reduction in battery performance
Rlonger charge times
Notes on battery care
Avoid storing or transporting the vehicle at
excessively high or low temperatures over a long
period.
If you park the vehicle and leave it stationary for
long periods:
Rcheck the condition of charge of the high-
voltage battery more often
Rconnect the vehicle to a power supply
This prevents self-discharge and damage to the
high-voltage battery.
Terms of use
Please note the information on exceptions and
limitations in warranty documentation and in
the Maintenance Booklet.
Handling the charging cable and charg- ing cable controls
Always read the notes on the charging cable on
the inside of the charge socket flap.
Do not leave the charging cable controls
(
Ypage 32) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.
30Charging the high-voltage battery
Driving and parking

To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
RNever lift or carry the controls by the charging
cable connector or the mains plug.
RTo transport the charging cable, the charging
cable 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"
(Ypage 29).
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:
Rthe power supply and the charging cable are
not damaged
Rthe 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 device against overvoltage
!Overvoltage in the mains supply may dam-
age the vehicle. For this reason, the vehicle is
equipped with a protection device against
overvoltage in the mains supply. This device
may be triggered during severe thunder-
storms, for example, and may lead to the buil-
ding's fuse being tripped and an interruption
in the power supply. These functions protect
the vehicle. After the building fuse is switched
on again, the charging process resumes auto- matically. Following an interruption in the
power supply or tripping of the building's fuse,
it may take up to 10 minutes for charging to
resume automatically.
Switch on the building protection system again
after it has been triggered. Otherwise, the
charging process cannot be continued.
General information about the charging
procedure
Pay attention to the "Important safety notes"
(Ypage 29).
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.

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 for connection to a mains socket.
Only use the charging cable supplied with the
vehicle or a charging cable approved for the
vehicle.
iIf you use the supplied 12 A charging cable
to charge a high-voltage battery:
Rthe charge time increases considerably
Relectrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station (
Ypage 35). Only
then can certified electrical energy consump-
tion levels be reached.
iThe charging process can vary depending on
the power supply. Therefore, always observe
the local information.

Setting the maximum charge current
GWARNING
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 cur-
rent. If necessary, lower the set charge cur-
rent or use another power 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:
Ron the controls of the charging cable
Rin the Settingsmenu of the on-board com-
puter (Ypage 43)
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:
Rit is not possible to set the charge current on
the charging cable
Rthe precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
How to set the maximum permissible charge
current on the charging cable, is described as
follows.
XTo adjust the setting: press button?
repeatedly until the desired setting is selec-
ted in display =.
