Automatic comfort-fit feature seat belt
The automatic comfort-fit feature reduces the
retracting force of the seat belts when they
are in normal use. It is available for the front
seats and for the rear outer seats (only for
vehicles with rear power seats).
Preventive occupant safety (PRE-
SAFE ®
)
GWarning!
The PRE-SAFE ®
system is intended to reduce
the effects of an accident on vehicle
occupants who are wearing their seat belt
properly. Despite your vehicle being equipped
with the PRE-SAFE ®
system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated. Therefore,
always drive carefully and adjust your driving
to the prevailing road, weather, and traffic
conditions.
The PRE-SAFE ®
system takes preventive
measures to better protect the occupants
from the possibility of personal injuries in the
following hazardous situations:
R emergency braking situations, e.g. if the
Brake Assist System (BAS) ( Y page 64) is
activated
or when
vehicles with DISTRONIC PLUS:
the BAS PLUS ( Y page 64) or the PRE-
SAFE ®
Brake ( Y page 69) is strongly
engaging
R when the radar sensors recognize the
immediate risk of collision in certain
situations (vehicles with DISTRONIC PLUS)
R critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
The PRE-SAFE ®
system takes the following
measures when it is activated:
R The front seat belts are pre-tensioned
automatically.
R If the front passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
R If a rear outer power seat (if so equipped)
is in an unfavorable position, the seat will
be adjusted to a position that seeks to
better protect the occupant.
R The system increases the air pressure in
the air pockets (on the sides of the seat
cushion and backrest) of the multicontour
and/or drive-dynamic multicontour front
seats.
R If the vehicle is equipped with multicontour
rear seats, the system increases the air
pressure in the air pockets (on the sides of
the seat backrest) of the multicontour rear
outer seats.
R If the vehicle is in a critical dynamic driving
situation, the door windows and the tilt/
sliding sunroof or panorama roof with tilt/
sliding panel also closes, except for a
minimal gap that remains open.
If the closing procedure of any of these
elements is blocked, it will stop and open
slightly.
Once the hazardous situation no longer exists
and an accident has been avoided, the PRE-
SAFE ®
system loosens the seat belt pre-
tension and decreases the air pressure in the
air pockets of the multicontour and/or drive-
dynamic multicontour seats. All of the PRE-
SAFE ®
system settings can be re-adjusted
following the critical driving event.
If the seat belts do not release:XAdjust the seat backrest to the rear until
the seat belt tension is reduced.
The locking mechanism releases.54Occupant safetySafety and security

To maintain the proper distance to the vehicle
in front of you and thus prevent a rear-end
collision, you must apply the brakes yourself.XBrake the vehicle immediately to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking. Observe the following
warning note.
The intermittent warning sound ceases and
the distance warning lamp · goes out
when the necessary distance to the vehicle
ahead is again established.
The PRE-SAFE ®
Brake can react to stationary
obstacles such as standing or parked vehicles
at road speeds of up to approximately 40 mph
(70 km/h).
GWarning!
If you do not receive visual or acoustic
warning signals, the PRE-SAFE ®
Brake may
R not have recognized the collision risk
R have been deactivated
R be malfunctioning
Apply the brakes yourself to avoid a collision.
The PRE-SAFE ®
Brake does not always clearly
interpret complex traffic situations. If a visual
and/or acoustic warning is issued in an
uncritical driving situation, or if the vehicle
brakes lightly, you can interrupt the PRE-
SAFE ®
Brake maneuver by pressing down all
the way on the accelerator pedal, using
kickdown, or releasing the brake pedal.
The PRE-SAFE ®
Brake maneuver is
terminated immediately when
R you avoid the obstacle by evasive steering
R you drive less than 9 mph (15 km/h)
R an obstacle can no longer be identified
ahead of you
R the system no longer senses the risk of a
collision
i The PRE-SAFE ®
Brake will remain passive
while DISTRONIC PLUS is switched on
( Y page 330).
After a hard collision or damage to the front
of the vehicle from an accident, have the
settings and operation of the radar sensors
checked by an authorized Mercedes-Benz
Center.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 236). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada.
When you switch off the radar system, the
following functions are deactivated:
R PRE-SAFE ®
Brake
R BAS PLUS ( Y page 64)
R DISTRONIC PLUS ( Y page 330)
R Blind Spot Assist ( Y page 359)XActivating and deactivating: Activate or
deactivate the PRE-SAFE ®
Brake using the
instrument cluster control system
( Y page 232).
After the function has been activated, the
PRE-SAFE ®
Brake indicator Ä appears
in the instrument cluster. When the HOLD
function is switched on, the PRE-SAFE ®
Brake indicator Ä will not appear.
Anti-theft systems
Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.

Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual.
COMAND introduction
COMAND operating safety
COMAND (
Cockpit Management and Data
System) is an information and operating
center for vehicle sound and communications
systems. It includes the radio and navigation
system, as well as other optional equipment
(satellite radio, telephone, etc.).
GWarning!
Any alteration of electronic components or
software can cause malfunctions.
Radio, satellite radio, amplifier, CD/DVD
changer, navigation module, telephone and
Voice Control Systems are interconnected.
Therefore, if one of the components is not
operational, or has not been removed/
replaced properly, the function of other
components could be impaired.
Such conditions might seriously impair the
operating safety of your vehicle.
We recommend to have any service work on
electronic components carried out by an
authorized Mercedes-Benz Center.
GWarning!
In order to avoid distraction which could lead
to an accident, the driver should enter system
settings while the vehicle is at a standstill, and
operate the system only when permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
COMAND supplies you with information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we
encourage the driver to stop the vehicle in a
safe place before answering or placing a call,
or consulting the COMAND screen to read
navigational maps, instructions, or
downloaded information.GWarning!
While the navigation system provides
directional assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver’s
personal responsibility. Maps do not cover all
areas nor all routes within an area.
GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not receive all
necessary safety information and warning for
the operation of your vehicle.
Availability of functions while the
vehicle is in motion
For safety reasons, certain COMAND
functions are not available while the vehicle
is in motion or they are only available to a
limited extent. You will notice this, for
example, by the fact that certain menu items
cannot be selected or that the COMAND
display shows a corresponding message.
