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

tension and decreases the air pressure in the
air pockets of the drive-dynamic multicontour
front 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 or seat slightly to
the rear until the seat belt tension is
reduced.
The locking mechanism releases.
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items.
For information on the seat belt adjustment
function as an integrated comfort feature of
the PRE-SAFE ®
system, see ( Y page 51).
NECK-PRO active front head
restraints
The NECK-PRO active front head restraints
are intended to offer the driver and front
passenger increased protection from
whiplash-type injuries. In the event of a rear-
end collision, the NECK-PRO active front head
restraints are designed to move forward and
up in the direction of travel. They thus provide
the head with increased support earlier on in
the collision sequence. The NECK-PRO active
front head restraints will move forward and
up whether the seats are occupied or not.
GWarning!
Do not attach any objects (e.g. hangers) to the
head restraint posts. Otherwise, the NECK-
PRO active front head restraints may not be
able to function properly or offer the intended
degree of protection they were designed for
in the event of a rear-end collision.
GWarning!
Only use seat or head restraint covers which
have been tested and approved by Mercedes-
Benz for your vehicle model.
Using other seat or head restraint covers may
interfere with or prevent the activation of the
NECK-PRO active front head restraints and/
or the deployment of the front side impact air
bags or pelvis air bags.
Contact an authorized Mercedes-Benz Center
for availability.
When the NECK-PRO active front head
restraints have been triggered in an accident,
the NECK-PRO active front head restraints
must be reset. Otherwise, the NECK-PRO
active front head restraints cannot offer any
additional protection in the event of another
rear-end collision.
For information on resetting the activated
NECK-PRO active front head restraints, see
“Resetting activated head restraints”
( Y page 316).
You cannot remove the NECK-PRO active
front head restraints.GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.
For information on head restraint adjustment,
see “Head restraint height” ( Y page 89), or
see “Head restraint fore and aft adjustment”
( Y page 89).

In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
