The ETDs for the rear outer seats will activate
with or without the respective seat belts
fastened.
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit
more snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
i The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest.GWarning!
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center.
The PRE-SAFE ®
system has electrically
operated reversible pre-tensioners that do
not require replacement after activation.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for the front
seats reduces the retracting force of the seat
belts when they are in normal use.
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 63) is
activated
or when
vehicles with DISTRONIC PLUS:
the BAS PLUS ( Y page 63) 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 The system increases the air pressure in
the air pockets (on the sides of the seat
cushion and backrest) of the drive-dynamic
multicontour front 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-Occupant safety53Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 53Z
GWarning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
BAS
GObserve Safety notes, see page 62.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
GWarning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
BAS PLUS
The Brake Assist System PLUS (BAS PLUS)
operates in emergency braking situations and
uses radar sensors to assess the traffic
situation. BAS PLUS assists you in braking at
speeds above approximately 20 mph
(30 km/h).
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 144). 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 BAS PLUS
R PRE-SAFE ®
Brake ( Y page 69)
R DISTRONIC PLUS ( Y page 149)GWarning!
BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident. Personal or fatal
injury to you or others may be the result.
i This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
BAS PLUS detects obstacles that are in your
driving path for a sufficient period of time to
permit the system to recognize these
obstacles. If you approach the detected
obstacle quickly, BAS PLUS calculates the
level of brake power boost appropriate for the
circumstance to supply when the driver
applies the brakes.
When you step quickly on the brake pedal in
an emergency braking situation, BAS PLUS
automatically regulates the brake power
Driving safety systems63Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 63Z
boost to a level that is suitable for the traffic
situation.
If BAS PLUS requires a particularly high brake
power boost, PRE-SAFE ®
is activated at the
same time.XKeep constant pressure on the brake pedal
until the emergency braking situation is
over.
During this process, the ABS prevents the
wheels from locking up.
The brakes will resume normal operation
after
R the brake pedal is released
R no obstacles are detected in your path
R the system no longer senses a risk of a
collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles
such as standing or parked vehicles at road
speeds of up to approximately 40 mph
(70 km/h).
BAS PLUS can only assist you when the radar
sensors are switched on and functional. You
can check whether the sensors are active by
switching on DISTRONIC PLUS
( Y page 149) or using the Radar sensors
function in the instrument cluster control
system.
GWarning!
BAS PLUS will only respond with brake
assistance if it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
After a hard collision or damage to the front
of the vehicle from an accident, have the
adjustment and operation of the radar
sensors checked by an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a radar
sensor malfunction, the braking system will
continue to function normally with full brake
boost and full standard BAS function.
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addiditon, Adaptive Brake provides the
HOLD function (Y page 161) and the hill-start
assist system ( Y page 160).
For more information on the brake system,
see ( Y page 254).
EBP
GObserve Safety notes, see page 62.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.
GWarning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.

Using the radar sensors, the PRE-SAFE ®
Brake detects obstacles that are in your
driving path for a sufficient period of time for
the system to recognize it. If you approach a
vehicle and the PRE-SAFE ®
Brake has
established that the distance to the vehicle
ahead at your current speed is so close that
the PRE-SAFE ®
Brake will not be capable of
slowing the vehicle sufficiently, the system
will initially warn you visually and acoustically.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will brake lightly automatically. The
PRE-SAFE ®
system ( Y page 53) is activated
when the distance to the vehicle ahead atyour current speed is so close that the PRE-
SAFE ®
Brake will not be capable of slowing
the vehicle sufficiently.
When the danger of a collision still persists
and you do not brake or accelerate
significantly, the PRE-SAFE ®
Brake may
initiate full application of the brakes
automatically.GWarning!
The PRE-SAFE ®
Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
The PRE-SAFE ®
Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRE-
SAFE ®
Brake will not react to persons,
animals, and approaching traffic or cross-
traffic.
The PRE-SAFE ®
Brake may not detect narrow
vehicles driving in front of you, such as
motorcycles and vehicles driving offset from
your vehicle center.
GWarning!
Depending on the vehicle speed, the
PRE-SAFE ®
Brake brakes your vehicle with a
maximum of 13 ft/s 2
(4 m/s 2
) before a
possible hard stop. This corresponds to about
40% of the maximum deceleration ability of
your vehicle. The driver must apply the brakes
additionally in order to prevent a collision. The
self-acting hard stop will be initiated when the
imminent danger of a collision exists, e.g.
when an evasive driving maneuver cannot
avoid an accident.

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 149).
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.XActivating and deactivating: Activate or
