Urban driving In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( Y
page 23).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
energy recuperation R
electric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h) .
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfort drive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.

switch-off ( Y

Refueling
Refueling
General information
Observe the important safety notes under
"Refueling" in the vehicle Operator's Manual. Pressure in the fuel tank must be released
before refueling. Otherwise, the fuel filler flap
cannot be opened.
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster
You can call up remote query and remote con-
figuration functions for your vehicle using online
access to the vehicle. This is possible from an
Internet-enabled computer, as well as many
modern smartphones.
Please call the Mercedes-Benz Customer Assis-
tance Center (USA) at the hotline number
1-800-FOR-MERCedes (1-800-367-6372) to
obtain the relevant Internet address.
Online access to the vehicle is restricted to the
contractual periods of mbrace. Activated
access to the mbrace emergency call system is
required for use.
In order to be able to use online access to the
vehicle, you must agree to the local terms of
use.
Further information about the supported end
devices, available languages and contractual
periods is available at any authorized Mercedes-
Benz Center.
In order to be able to call up online access to the
vehicle, the vehicle must be connected to the
Internet ( Y
page 37).
Notes on data protection Remember that online access to the vehicle
offers access to your data.
i Prevent unauthorized persons from
accessing this data.
Every person who has access to the informa-
tion stated can use the functions of the online
access to the vehicle.
i Information when selling a vehicle or
buying a used vehicle: R
If you sell your vehicle, you are obliged to
delete the vehicle from your personal area
on the online access to the vehicle. R
If you have bought a used vehicle, it is pos-
sible that the previous owner still has
access to the online access to the vehicle.
Calling up functions
The online access to the vehicle allows you
access to your vehicle's information and func-
tions using remote query and remote configu-
ration. The following functions can be accessed: R
request the current condition of charge of the
high-voltage battery R
program the departure time ( Y
page 44)R
set or activate the "Pre-entry climate control
at departure time" function (see the separate
COMAND operating instructions)
Information on additional functions and operat-
ing instructions can be found within the online
access to the vehicle.
Connecting the vehicle to the Internet
i This function is not available in all countries
and requires activated access to the mbrace
emergency call system.
You can use the online access to the vehicle if
the vehicle has a connection to the Internet via a
mobile phone network. The necessary data is
transmitted by radio. The vehicle automatically
recognizes whether a connection to the Internet
is possible or not. No presets are necessary.
i Restrictions in reception are possible if the
vehicle is in an underground car park, for
example. Restrictions may also occur in areas
with poor mobile network coverage.

Important safety notes
G WARNIN G
If you operate information systems and com-
munication equipmen t integrate d in th e vehi-
cle while driving , you will be distracte d from
traffic conditions. You could also lose control
of th e vehicle. Ther e is a ris k of an accident.
Only operate th e equipmen t when th e traffic
situation permits. If you are no t sur e that this
is possible , park th e vehicl e payin g attention
to traffic condition s and operate th e equip-
men t when th e vehicl e is stationary.
You must observ e th e legal requirements for th e
country in whic h you are currentl y driving when
operating th e on-board computer.

If th e instrumen t cluste r has faile d or mal-
functioned, you may no t recognize function

impaired . Ther e is a ris k of an accident.
Pull ove r as soo n as it is saf e to do so and
consult a qualified specialist workshop.

cluster. R
Area C to D (E-DRIVE):
This shows th e electric output from th e elec -
tric motor, e.g. during electric operation or in
boos t mode.
When th e motor is switched on , th e needle is
at limi t C . Wit h increasing pressur e on th e
accelerato r pedal th e needle moves from C
to D .
Driving with th e electri c motor: when th e
needle reaches limi t D th e combustion
engin e is switched on . If th e display
approaches limi t D and you remove your foo t
from th e accelerato r pedal , th e needle drops
again . The combustion engin e is no t switched
on . At low speeds, you can thereby control th e
electric operation usage so that you only driv e
in electric mode.
Driving with th e combustion engine: th e
electric motor support s th e combustion
engin e by providing additional driv e torque
(boost mode) until th e needle reaches
limi t D .
You can also select th e operating mod e of th e
