Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshift the transmission out of park position P
Rstart the vehicle's drive system.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to theSmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile
phone or another SmartKey.
Rwith metallic objects, e.g. coins or metal
foil.
Rinside metallic objects, e.g. a metal case.
Vehicles with KEYLESS-GO start function:
do not keep the SmartKey in the cargo com-
partment. Otherwise, the SmartKey may not
be detected, e.g. when starting the drive sys-
tem using the Start/Stop button.

Opening and closing
The SmartKey centrally locks/unlocks:
Rthe doors
Rthe tailgate
Rthe charge socket flap
The turn signals flash once when unlocking
and three times when locking.
When the locator lighting is activated in Audio
20/COMAND, it also lights up when it is dark after the vehicle is unlocked with the remote
control (see the separate operating instruc-
tions).
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using
the on-board computer (
Ypage 198).
KEYLESS-GO
General notes
Bear in mind that the drive system can be
started by any of the vehicle occupants if
there is a key in the vehicle.
Locking and unlocking
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a con-
ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the &button on the SmartKey.
The driver's door and the door at which the
handle is used, must both be closed. The
SmartKey must be outside the vehicle. When locking or unlocking with KEYLESS-GO, the
distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example:
Rwhen starting the drive system
Rwhilst driving
Rwhen the external door handles are
touched
Rduring convenience closing
XTo unlock the vehicle: touch the inner
surface of the door handle.
XTo lock the vehicle: touch sensor sur-
face :or;.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-
ton. A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example,
when starting the drive system.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the drive system starts
immediately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in
the ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (
Ypage 73).
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile
phone or another SmartKey.
Rwith metallic objects, e.g. coins or metal
foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-
GO.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will not be able to start the drive system
with the Start/Stop button until the vehicle is unlocked again.
If you lock the vehicle centrally using the but-
ton on the front door (
Ypage 80), you can
continue to start the drive system with the
Start/Stop button.

General notes
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.
You must observe the legal requirements for
the country in which you are currently driving
when operating integrated information sys-
tems and communications equipment.
Only use information systems and communi-
cations devices if this is permitted while driv-
ing and if the traffic situation permits. You
may otherwise be distracted from the traffic
conditions, cause an accident and injure
yourself and others.
From the "My Mercedes Electric - Vehicle
Homepage", you can call up remote query and
remote configuration functions for your vehi-
cle. This is possible from an Internet-enabled
computer, as well as many modern smart-
phones.
You can access the "Vehicle Homepage" via
your web browser.
Please call the Mercedes-Benz Customer
Assistance Center (USA) at the hotline num-
ber
1-800-FOR-MERCedes (1-800-367-6372)
to obtain the relevant Internet address.
In order to use the "Vehicle Homepage", you
must agree to the applicable terms of use.
The contractual periods of mbrace apply to
the "Vehicle Homepage". To use the "Vehicle
Homepage", you require an activated mbrace
access and a separate activation/registra-
tion for the "Vehicle Homepage". Further information about the supported end
devices, available languages and contractual
periods is available at any authorized
Mercedes-Benz Center.
In order to call up the "Vehicle Homepage",
the vehicle must be connected to the Inter-
net.
This is possible via the radio module
(
Ypage 153).
Notes on data protection
Bear in mind that the "Vehicle Homepage"
offers access to your data. Therefore, look
after the vehicle verification code (VVC) and
your user details carefully.
The vehicle verification code (VVC) is required
when you register for the first time on the
"Vehicle Homepage". Using this code, the
vehicle and the user access are linked to each
other on the "Vehicle Homepage", enabling
the intended usage. You can obtain further
information from an authorized Mercedes-
Benz Center.
Prevent unauthorized persons from
accessing this data.
Every person who has access to the informa-
tion stated can use the functions on the "Vehi-
cle Homepage".
RIf you sell your vehicle, you are obliged to
delete the vehicle from your personal area
on the "Vehicle Homepage". Additionally,
you must destroy documents containing
the vehicle verification code (VVC).
RIf you have bought a used vehicle, it is pos-
sible that the previous owner still has
access to the "Vehicle Homepage". If in
doubt, have a new vehicle verification code
(VVC) issued by the Mercedes-Benz Center
after purchase. With the code you can set
up access to your vehicle, as described in
the section "Setting up a personal area" on
the Vehicle Homepage". There, you may
also deactivate the existing access of the
previous owner.
152High-voltage battery
Driving and parking
Calling up functions in the "My
Mercedes Electric - Vehicle Homepage"
The "My Mercedes Electric - Vehicle Home-
page" allows you access to information about
your vehicle and its functions using remote
query and remote configuration. For example,
climate control can be activated using remote
configuration which means that it need not be
set in the vehicle. Power for the climate con-
trol is primarily supplied via the charging
cable connected to the mains supply. In this
way, the range of the vehicle in most cases is
not reduced. If climate control is activated,
the battery charge level and thus the range
may be reduced. The "Vehicle Homepage"
provides you with information all about how
to use your vehicle.
If the vehicle is entered in your personal area
of the "Vehicle Homepage", you can also
access the following functions:
Rrequest the current condition of charge of
the high-voltage battery
Rprogram the departure time (Ypage 195)
Rorder and activate the "Pre-entry climate
control at departure time" function
If the vehicle is charging, the predicted charg-
ing time and the predicted range will also be
shown.
This data is estimated and may be influenced
by the following factors:
Routside temperature
Rswitched on consumers, e.g. climate con-
trol and seat heating
Rpersonal driving style
Rroad and traffic conditions
Rroute characteristics
Therefore, allow for a sufficient reserve.
iInformation on additional functions and
operating instructions can be found on the "Vehicle Homepage".
Connecting the vehicle to the Internet
Via a radio module
This function is not available in all countries
and requires an activated mbrace access.
You can use the "Vehicle Homepage" if the
vehicle has a connection to the Internet via a
mobile phone. The radio module uses a
mobile phone connection and transmits the
necessary data by radio. The vehicle auto-
matically recognizes whether a connection to
the Internet via the radio module is possible
or not. No presets are necessary.
To enable the transfer of data via the mobile
communications module, you do not need a
SIM card.
iRestrictions 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.
Parking
Important safety notes
GWARNING
If you release the parking brake on uphill or
downhill gradients, the vehicle can begin to
move when in park position P. There is a risk
of an accident.
To avoid hazardous situations:
Rprevent the parked vehicle from rolling on
uphill or downhill gradients by always
applying the parking brake.
Rdo not park the vehicle on uphill or downhill
gradients if the parking brake is malfunc-
tioning.
