D
- Sporty driving or driving on a
downhill gradient
The brake pedal does not need to
be used as often because the
extent of the deceleration is
greater than in D.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal. D
AUTO
(radar-
based) The intensity of recuperation is
automatically adjusted to the cur-
rent traffic situation.
Default setting In levels
Dand D-
, deceleration can be control-
led in an infinitely variable manner using the
accelerator pedal.
The braking performance of the electric motor
using recuperative braking is, in some operating modes, either reduced or not effective:
R when the charge status of the high-voltage
battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when driving close to the maximum design
speed
R when the vehicle is almost stationary
R in transmission position N
R during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be sufficient. If necessary, counteract the reduced regenerative braking effect by applying the
brake yourself.
Radar-based recuperation The vehicle uses the sensors of COLLISION PRE-
VENTION ASSIST PLUS during radar-based
recuperation (D AUTO
). The sensors detect the
distance to the vehicle ahead and its speed. The intensity of recuperation is then automatically
adjusted to the current traffic situation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely vari-
able from overrun mode (no recuperation) to
maximum recuperation.
Maintain sufficient distance to the vehicle in
front. Mercedes-Benz recommends that you activate COLLISION PREVENTION ASSIST PLUS
as a visual and acoustic aid.
Examples of radar-based recuperation:
R Approaching a slower vehicle, a decelerating
vehicle or when following a vehicle downhill.
Your vehicle decelerates slightly and increa-
ses recuperation.
R Driving when no vehicle is detected in front or
when a vehicle is detected in the far distance or an accelerating vehicle is detected. Your
vehicle switches to overrun mode at higher
speeds.
R Driving on a steep downhill slope. Accelera-
tion downhill is reduced and recuperation is
increased. This is comparable with shifting
down when driving downhill.
X To activate radar-based recuperation: pull
steering wheel gearshift paddle :or;
towards you and hold for about one second.
X To deactivate radar-based recuperation:
briefly pull steering wheel gearshift paddle
:
or ; towards you.
If you change between radar-based and manual
recuperation, the following levels are activated
depending on the selection via the steering
wheel gearshift paddles: :
Steering wheel
gearshift paddle - selects
D-
(maximum
recuperation) ;
Steering wheel
gearshift paddle + selects
D+
(overrun) In particular, the function of the radar sensors
can be impaired in the case of:
R
dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
Following damage to the front end of the vehicle, have the radar sensor settings and operation
checked at a qualified specialist workshop
immediately. This also applies to collisions at
slow speeds where there is no visible damage to the front of the vehicle.
If the radar sensors are not available, the system
switches automatically to level Dwith moderate Transmission

recuperation. Have the radar sensors checked
at a qualified specialist workshop immediately.
Automatic adjustment of recuperation
on downhill gradients The vehicle can detect steep downhill gradients.
To reduce acceleration downhill and to charge
the high-voltage battery, recuperation is
increased steplessly. This is comparable to the
engine brake in a combustion engine when you
downshift a gear on a downhill gradient.
Automatic adjustment of recuperation on down-
hill gradients is available in level DAUTO
or on
vehicles without steering wheel gearshift pad-
dles in level D.
Intelligent recuperation The vehicle uses the map and camera data of
Traffic Sign Assist in addition to the sensors of
COLLISION PREVENTION ASSIST PLUS during
radar-based recuperation ( DAUTO
). The rate of
recuperation is then automatically adjusted to
the current traffic situation, taking the current
and future maximum speed into account. High-voltage battery
Important safety notes
G
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 vehicle's high-voltage electrical system
checked by a qualified specialist workshop. G
WARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery could exceed a critical value. In this case, flammable gas
escapes through a vent valve in the vehicle's
underbody. The gas can ignite. There is a risk of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements. G
DANGER
Connecting the charging cable to the mains
supply via incorrectly installed mains sockets or by means of adapters, extension cables or
similar could cause a fire or an electric shock. There is a risk of fatal injury.
To avoid such risks, observe the following:
R Only connect the charging cable to mains
sockets:
- which have been properly installed and
- which have been inspected by a qualified
electrician
R For safety reasons, only use charging
cables which have been supplied with the
vehicle or which have been approved for
this vehicle.
R Never use a damaged charging cable.
R Do not use:
- extension cables
- extension reels
- multi-outlet sockets
R Never use socket adapters 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 of an
electric vehicle.
R Observe the safety notes in the operating
instructions for the socket adapter. G
DANGER
Connecting the charging cable to the wallbox via an incorrectly installed wallbox or adapter,
extension cable or similar could cause a fire or an electric shock. There is a risk of fatal injury. 134

To avoid hazardous situations, observe the
following:
R Only connect the charging cable to a wall-
box:
- which has been properly installed and
- which has been inspected by a qualified
electrician
R For safety reasons, only use charging
cables that have been tested and approved
by the manufacturer for charging the high-
voltage battery in an electric vehicle.
R Never use damaged charging cables.
R Do not extend the charging cable.
R Never use adapters.
R Observe the safety notes in the operating
instructions for the wallbox.
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 electrical
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-voltage
electrical system components that are
marked with a warning sticker. Notes on the charging cable
Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
(Y page 140) hanging loose from a mains
socket. Otherwise, this could result in a poor
contact with the mains socket and malfunctions
when charging the vehicle. To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
R never lift or carry the controls by the charging
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 Observe the important safety notes
(Y
page 134).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting 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
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Protection device 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 without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
protection device against overvoltage has been triggered. Otherwise, the charging process can-not be continued. The high-voltage battery will
not be charged and you may not be able to drive
the vehicle. High-voltage battery

If other devices are protected by the same pro-
tective device, these are switched off as well
when the protective device is triggered. Ensure
that these other devices are still operational
after reactivating the protection device. Influences on the charging behaviour

Terms of use Observe the following notes:
R information on exceptions and limitations in
warranty documentation and in the related
Service Booklet
R maintenance notes for the high-voltage bat-
tery in the Service Booklet
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 (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 fol-
lows:
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 station/
wallbox while the vehicle is stationary
The high-voltage battery can be charged in a
single-phase nominal voltage range from 100 V to 240 V. The corresponding three-phase nom-
inal voltage range enables charging up to 400 V.
If the charge status drops to less than 13%, the
high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a charge status of 5%, the performance of the vehicle is reduced. The vehicle's high-volt- age electrical system switches off at a charge
status 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 sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer
able to provide the normal electrical power out- put.
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 automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 173).
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 supply.
Temperatures below Ò25 † and over 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 Battery

tus below 20%.
You can check the charge status in the charge
level display (Y page 174).
Further information on the "Energy flow display" can be found in the "Trip" menu (Y page 177).136

Energy consumption and range
This range is reduced by:
R high and low outside temperatures
R a non-anticipatory driving style
R switching on consumers, e.g. air-conditioning
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:
R a reduction in battery performance
R longer charge times
In extreme cases, this could mean that the vehi- cle cannot be started. For this reason, connect
the charging cable when leaving the vehicle
parked for long periods at low outdoor temper-
atures.
As a result of its basic characteristics, the
amount of energy available from the high-volt-
age battery decreases over the course of its life.
This reduces:
R the maximum range that can be achieved by
the vehicle
R the 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:
R an anticipatory driving style
R reducing the use of electrical consumers
R having 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
(Y page 178) and range (Y page 178).
RANGE PLUS If you activate RANGE PLUS, the operating win-
dow of the battery will be extended at the next
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:
R long journeys are planned or
R the availability of charging stations at the des-
tination is limited The more often RANGE PLUS is used, the more
the extended range is reduced.
Therefore always check the range display for
every journey (Y

Charging cable 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 three-phase 32 A
charging cable. A single-phase 13 A charging
cable (Switzerland: 16 A) can be optionally
ordered.
When charging the vehicle using the mains
socket, use the single-phase 13 A (Switzerland:
16 A) charging cable.
Observe the "Important safety notes"
(Y page 134).
If you use the supplied 13 A charging cable
(Switzerland: 16 A) as opposed to the 32 A
charging cable to charge the high-voltage bat-
tery:
R the charge time increases considerably
R electrical consumption increases considera-
bly
For this reason, always charge the high-voltage
battery from a wallbox (Y page 142) or at a
charging station (Y page 142). Only then can
certified electrical energy consumption levels
be reached.
i The charging process can vary depending on
the charging station. Therefore, always
observe the local information. 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 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.
! 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.
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
mains 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
mains supply.
i The value of the maximum setting and the
relevant adjustment values may vary depend-
ing on the country.
Before charging the high-voltage battery, have
the maximum permissible charge current for the relevant power socket checked by an electri-
cian.

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.
If the charge current values that have been set
on the charging cable and the on-board com-
puter are different, the high-voltage battery is
charged using the lower value.
If the vehicle requires more time than usual to

General notes When charging your vehicle from a wallbox, use
the three-phase 32 A charging cable supplied.
The charging cable is stored in a bag in the boot.
Only use charging cables that have been tested
and approved by the manufacturer for charging
the high-voltage battery in an electric vehicle.
Observe the "Important safety notes"
(Y page 134). 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 charg-
ing station.
When the vehicle is connected to the charging
