The high-voltage battery can be charged as
follows:
Rthrough energy recuperation while the
vehicle is in motion
Rwith the charging cable at a mains socket
while the vehicle is stationary
Rwith the charging cable at a charging sta-
tion while the vehicle is stationary
The high-voltage battery can be charged
using a single-phase charging cable in a volt-
age range from 100 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.
High and low outside temperatures
Low outside temperatures
The efficiency of the high-voltage battery is
significantly reduced at very low outside tem-
peratures. 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 bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age battery is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (
Ypage 183).
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.
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
Battery level too low. Stop and
charge immediatelymessage. This pro-
tects the battery from exhaustive discharge.
It is not possible to restart the drive system
until after charging.
Do not leave the vehicle parked for longer
than 14 days with a high-voltage battery con- dition of charge below 20%.
You can check the condition of charge in the
charge level display (
Ypage 184).
Further information on the "Energy flow dis-
play" can be found in the "Trip" menu
(
Ypage 187).
Energy consumption and range
This range is reduced by:
Rhigh and low outside temperatures
Ra non-anticipatory driving style
Rswitching on consumers, e.g. air-condition-
ing system or heating.
The battery's physical characteristics are
such that leaving the vehicle parked for an
extended period at low outdoor temperatures
without charging it can lead to:
Ra reduction in battery performance
Rlonger charge times
In extreme cases, this could mean that the
vehicle cannot be started. For this reason,
connect the charging cable when leaving the
vehicle parked for long periods at low outdoor
temperatures.

As a result of its basic characteristics, the
amount of energy available from the high-
voltage battery decreases over the course of
its life.
This reduces:
Rthe maximum range that can be achieved
by the vehicle
Rthe maximum output (acceleration) of the
vehicle
You can actively reduce the energy consump-
tion of your vehicle in a number of ways, for
example, by:
Ran anticipatory driving style
Rreducing the use of electrical consumers
Rhaving the vehicle regularly maintained
The charging time of the high-voltage battery may change over the course of its life.
Observe the displays on energy usage
(
Ypage 188) and range (Ypage 188).
RANGE PLUS
If you activate RANGE PLUS, the operating
window of the battery will be extended at thenext charging process. An extended driving
range will be available to you for the next
journey.
Using RANGE PLUS shortens the service life
of the battery. Therefore, only use RANGE
PLUS if, for example:
Rlong journeys are planned or
Rthe availability of charging stations at the
destination is limited
The more often RANGE PLUS is used, the
more the extended range is reduced.
Therefore always check the range display
before every journey (
Ypage 188).

Charging high-voltage battery via the

Charging cable
Important safety notes
!Only use the charging cable to charge the
high-voltage battery. Do not use the charg-
ing cable for other purposes. It may other-
wise be damaged.
The vehicle is supplied with a single-phase 12
A charging cable. Only use the charging cable
included with the vehicle, which has been
approved for vehicle use.
Pay attention to the "Important safety notes"
(
Ypage 140).

Driving and parking
Page 149 of 342

If 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 149). Only
then can certified electrical energy consump-
tion levels be reached.
iThe charging process can vary depending
on the charging station. Therefore, always
observe the local information.
Stowing the charging cable
The charging cable can be stowed in a bag in
the trunk of the vehicle. To do so, the bag
must be secured to the cargo tie-down rings
using the retaining strap provided.

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
High-voltage battery147

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.
iThe 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.
XTo adjust the setting: press button?
repeatedly until the desired setting is selec-
ted in display =.
RTwo LEDs are flashing: minimum setting
RAll LEDs are flashing: maximum setting
Information about the charging time
(
Ypage 338)
If, after the charging process, the charging
cable is:
Rleft connected to the power socket, the
currently selected values will be used for
the next charging process.
Rremoved 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.
If the charge current values that have been
set on the charging cable and the on-board computer are different, the high-voltage bat-
tery is charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:
Rthe settings of the maximum charge cur-
rent on the controls of the charging cable
Rthe settings of the maximum charge cur-
rent in the menu of the on-board computer

General notes
Only use charging cables that have been tes-
ted and approved by the manufacturer for
charging the high-voltage battery in an elec-
tric vehicle.
Pay attention to the "Important safety notes"
(
Ypage 140).
Charging communication at a charging
station
The charging station first has to be activated
before you can charge at a charging station.
You can activate the charging station by using
an RFID card or via telephone activation.
Observe the on-site operator instructions for
the charging station.
When the vehicle is connected to the charging
station, information and details on technical
parameters are exchanged. It can thus take
up to 30 seconds for the charging process to
begin.
