Only a seat belt which is worncor rectly can pro-

th e de tected accident situation, seat belt tension-

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
