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.
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 (Ypage 178).

Driving and parking
Z
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
Por you have previously driven faster than
2 mph (3 km/h).
iEnsure that you do not depress the accel-
erator 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.
The vehicle is braked for as long as the handle
of the electric parking brake is pressed. The
longer the electric parking brake handle is
depressed, the greater the braking force.
During braking:
Ra warning tone sounds
Rthe ReleasePark.Brakemessage 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.
iYou can obtain information about trickle
chargers from a qualified specialist work-
shop.

General notes
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.

Starting the engine
The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only after
the power demanded by the driver exceeds the
available power that the electric motor can cur-
rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper-
ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine.
