minor deformation. This is the case if, for
example, very rigid vehicleparts such as longi-
tudinalbody members are hit, and sufficient
decelerationoccurs as aresult.
If the restraint system control unit detects a
side impact or if the vehiclerolls over, the
applicable components of the restraint system
are deployedindependently of each other
depending on the apparent type of accident.
R
Side impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the
driver'sseat
The side impact air bag on the front
passenger side deploys under the following
conditions:
-
the OCS system detects that the front
passenger seat is occupied or
-
the seat belt buckle tongue is engagedin
the belt buckle of the front passenger
seat
R
Head bag on the side of impact, independ-
ently of the use of the seat belt and inde-
pendently of whether the front-passenger
seat is occupied
R
Emergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
R
Head bags on the driver'sand front-
passenger side in certain situations when
the vehiclerolls over, if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
i
Not all air bags are deployedinanacci-
dent. The various air bags work independ-
ently of each other .
How the air bag works is determined by the
severity of the accident detected, especially
the vehicledecelerationoracceleration and
the apparent type of accident:
R
Head-on collision

Side impact

NECK-PRO head restraints
Important safety notes
G
WARNING
The function of the head restraint may be
impaired if you:
R
attach objects such as coat hangers to
the head restraints, for example
R
use head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the
event of an accident. In addition, objects
attached to the head restraints could endan-
ger other vehicleoccupants. There is an
increasedrisk of injury.
Do not attach any objects to the head
restraints and do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraints reduce the likeli-
hood of head and chest injuries. The NECK-
PRO head restraints on the driver'sand front-
passenger seats are moved forwards and
upwards in the event of arear-end collision of
acertain severity. This provides better head
support.
If the NECK-PRO head restraints have been
triggeredinanaccident, you must reset the
NECK-PRO head restraints on the driver’sand
front-passenger seat (Y page 53).Other-
wise,the additional protection willnot be
available in the event of another rear-end colli-
sion. You can recognize when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints checked for
functionality at aqualified specialist workshop
after arear-end collision.
