Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 23). Running-in notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
process.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after several hundred kilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Before driving away, you must ensure that,
for your own safety and to avoid damage, the charging cable has been removed from the
vehicle socket. Otherwise, you cannot shift
the transmission out of position P.
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 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 Driving

Important safety notes G
WARNING
If children are left unsupervised in the vehicle, they could:
R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncoming traffic
R operate vehicle equipment and become
trapped, for example
In addition, the children could also set the
vehicle in motion by, for example:
R releasing the parking brake
R shifting the transmission out of park posi-
tion P
R starting the vehicle's drive system
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 and animals unattended in the vehi-
cle. Keep the keys out of the reach of children.
Vehicles with an electric motor generate signif- icantly less noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This can happen, for example, when
you are parking and your vehicle is not seen by
other road users. This requires you to adopt a
particularly anticipatory driving style, as it is
necessary to allow for the possibility that other
road users may behave unpredictably.
The vehicle can be equipped with a sound gen-
erator. The sound generator is activated so that other road users can hear your vehicle better.
The sound generator is activated at speeds
under 30 km/h and switches off automatically
at higher speeds.
Starting procedure using the Start/
Stop button The Start/Stop button can be used to start the
vehicle manually without inserting the key into
the ignition lock. The key must be in the vehicle
and the Start/Stop button must be inserted in
the ignition lock. Driving

the electrical parking brake is released auto-
matically. If the brake pedal is not depressed,
the DIRECT SELECT lever can still be moved but
the parking lock remains engaged.
Make sure that no charging cables are connec-
ted. The parking lock cannot be released if a
charging cable is connected. Hill start assist
Hill start assist will aid you when pulling away on
a hill. It holds the vehicle for a short time after
you have removed your foot from the brake
pedal. This gives you enough time to move your foot from the brake pedal to the accelerator
pedal and depress it before the vehicle begins to
roll away. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:

Manually adjustable recuperation :
Left-hand steering wheel gearshift paddle -
; Right-hand steering wheel gearshift paddle
+
You can increase or reduce recuperation in over-
run mode using the steering wheel gearshift
paddles. When you remove your foot from the
accelerator pedal, recuperation occurs. The
electric motor is then used as a alternator and
energy is recovered while driving. The recuper- ated electrical energy is stored in the high-volt-
age battery. A higher energy recuperation level
means that the vehicle is braked more power-
fully.
If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self.
Information on the Recuperative Braking Sys-
tem (Y page 67).
X To decrease recuperation: pull right-hand
steering wheel gearshift paddle ;.
X To increase recuperation: pull left-hand
steering wheel gearshift paddle :.
The various recuperation levels are shown in the
transmission position display once Dhas been
selected (Y page 129).
The following recuperation levels are available in
overrun mode:
R no recuperation (D +
, coasting mode)
R moderate recuperation ( D)
R high recuperation ( D-
)
R recuperation depending on the traffic situa-
tion (D AUTO
, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation per-
formance value shown in the power display
(Y page 173).
Every time drive position Dis selected, the
transmission switches into recuperation level

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.

Depending on the temperature, the engine
cooling system and battery cooling system
may audibly switch on when the charging
cable is connected or during the charging
process.
Removing the charging cable !
Before driving away, you must ensure that,
for your own safety and to avoid damage, the charging cable has been removed from the
vehicle socket. Otherwise, you cannot shift
the transmission out of position P.
When the charge level display reaches 100%,
the battery is fully charged (Y page 174).
The indicator lamps in the vehicle socket and on the charging cable may stay on for up to
30 seconds after the charging cable has been
disconnected.
When the battery is charged:
X Unlock the vehicle.
The Ý right indicator lamp Bon vehicle
socket Cgoes out. The Ìleft indicator
lamp Aon vehicle socket Clights up white.
X Remove the charging cable from vehicle
socket Cwithin 30 second s. Otherwise the
vehicle will relock the vehicle socket.
X Close socket cap =.
X Close the charge socket flap.
X Remove the charging cable from the mains
socket.
X Stow the charging cable safely in the vehicle
(Y page 140).
If the charging cable cannot be removed from
the vehicle socket, unlock the charge socket
flap manually using the emergency release
(Y page 143). Charging a high-voltage battery at a
charging station/wallbox
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
station, information and details on technical
