General notes
It is recommended that you charge your vehicle
using a wallbox or at a charging station.
Make sure that the maximum charging current is
not limited in the Settings
menu of the on-
board computer. You must select the maximum
value if charging at a wallbox or a charging sta-
tion (
Ypage 272).
Pay attention to the "Important safety notes"

General information
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
iOperation of integrated information sys-
tems and communications equipment in
the vehicle: you must observe the legal
requirements for the country in which you are currently driving.
Via the "My Mercedes Electric - Vehicle Home-
page", you can call up remote query and remote
configuration functions for your vehicle. This is possible from an Internet-enabled computer, as
well as many modern smartphones.

Driving and parking
Rthe seat belt has been fastened
Ryou depress the accelerator pedal
If the automatic transmission is in position R,
the trunk lid must be closed.
If your seat belt is not fastened, the following
conditions must be fulfilled to automatically
release the electric parking brake:
Rthe driver's door is closed.
Ryou have shifted out of transmission position
P or you have previously driven faster than
2 mph (3 km/h).
Ensure that you do not depress the accelerator
pedal unintentionally. Otherwise the parking
brake will be released and the vehicle will start
to move.
Emergency braking
The vehicle can also be braked during an emer-
gency by using the electric parking brake.
XWhile driving, push handle :of the electric
parking brake (Ypage 190).
The vehicle is braked as long as you keep
handle :of the electric parking brake
pressed. The longer electric parking brake
handle :is depressed, the greater the brak-
ing force.
During braking:
Ra warning tone sounds
Rthe Please Release Parking Brakemes-
sage appears
Rthe red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster flashes
When the vehicle has been braked to a stand-
still, the electric parking brake is engaged.
Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked for longer than six
weeks, the vehicle may suffer damage as a
result of lack of use.
XVisit a qualified specialist workshop and seek
advice.
PLUG-IN HYBRID vehicles: observe the impor-
tant safety notes for the high-voltage battery
(

Driving tips
General driving tips
Important safety notes
GWARNING
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.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while
driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not needed.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-

HYBRID operating mode is available.
If you switch from automatic drive program Sto
automatic drive program Eor E+ ,HYBRID oper-
ating mode continues to be selected.
If manual drive program Mis deactivated, the
automatic transmission shifts:
Rinto the automatic drive program that was last

is automatically selected.
Power meter
The power meter supports you in electric mode
and displays the output obtained.
If you select the E-MODEoperating mode, the
instrument cluster will display the power meter
instead of the tachometer.
iThe tachometer appears again if:
Ryou select HYBRID,E-SAVE orCHARGE
Rthe current state of charge of the high-volt-
age battery is too low to drive the vehicle in
the E-MODE electrical operating mode
The power meter is divided into the following
areas:
RLimit:(OFF):
If the needle reaches limit :, the electric
motor and the combustion engine are
switched off.
RArea ;to? (CHARGE):
This shows the recuperated energy which is
stored in the high-voltage battery as electrical energy.
The more recuperated energy the high-volt-
age battery has, the further needle ?travels
in direction =. When the needle reaches limit
=, the maximum amount of recuperative
braking power has been reached.
In addition to the recuperative braking power,
the mechanical brakes are activated in the
area between ;and =.
ROutput range of electric motor: ?toA:
The electric output of the electric motor is
displayed here. When the power meter needle
reaches position ?, the electric motor is
operational. With increasing pressure on the
accelerator pedal, the needle moves towards
A.
The output limit of the electric motor Acan
be felt via the additional pressure point in the
haptic accelerator pedal.
If you do not press the haptic accelerator
pedal beyond the pressure point, you can
control electric operation, at low speeds, to
only drive in electric mode.
ROutput range of combustion engine: AtoB:
The output of the combustion engine and the
electric motor is displayed here. When the
power meter needle reaches position Aand
you press the haptic ac
celerator pedal
beyond the pressure point, then the combus-
tion engine is switched on.
