de tected accident situation, seat belt tensioners
and/or airbags supplement the pr otection o.ered
by a cor rectly wornseat belt. Seat belt tensioners
and/or airbags are not deplo yed in every acci-
dent. In order
forth ere straint system toprov ide the
intended le vel of pr otection, each vehicle occu-
pant must obser vethefo llowing information:
R Fasten seat belts co rrectl y.

ble.
R Always secure persons under 1.50 m tall in an
additional restraint system suitable for
Mercedes-Benz vehicles.
Ho wever,no system available today can com-
ple tely eliminate injuries and fatalities in every
accident situation. In particular, the seat belt and
airbag generally do not pr otect against objects
penetrating theve hicle from the outside. It is also
not possible tocomple tely rule out therisk of
injury caused bythe airbag deploying. Limit Limit
