restraint system includes thefo llowing compo-
nents:
R Seat belt system
R Airbags
R Child restraint system
R Child seat secu ring systems
The restraint system can help pr event theve hicle
occupants from coming into contact with parts of
th eve hicle interior in theev ent of an accident. In
th eev ent of an accident, there straint system can
also reduce thefo rc es towhich theve hicle occu-
pants are subjected.
Only a seat belt which is worncor rectly can pro-
vide the intended le vel of pr otection. Depending on
th e de tected accident situation, seat belt tension-
ers and/or airbags supplement the pr otection
o.ered bya cor rectly wornseat belt. Seat belt ten-
sioners and/or airbags are not deplo yed in every
accident.
In order forth ere straint system toprovide the
intended le vel of pr otection, each vehicle occupant
must obser vethefo llowing information:
R Fasten seat belts co rrectl y.
R Sit in an almost upright seat position wi th their
back against the seat backrest.
R Sit with their feet resting on the 0oor, if possi-
ble.
R Always secure persons under 1.50 m tall in an
additional restraint system suitable for
Mercedes-Benz vehicles.
Ho wev er, no system available today can comple tely
eliminate injuries and fatalities in every accident
situation. In particular, the seat belt and airbag
ge nerally do not pr otect against objects penetrat-
ing theve hicle from the outside. It is also not pos-
sible tocomple tely rule out therisk of injury
caused bythe airbag deploying. Limit Limit
