Important Safety Belt Information
The use of safety belts helps to restrain you and your
passengers in case of a collision. In most states and in Canada
the law requires their use.
Safety belts provide best restraint when:
the seatback is upright
the occupant is sitting upright (not slouched)
the lap belt is snug and low on the hips
the shoulder belt is snug against the chest
the knees are straight forward
To help you remember to fasten your safety belt, a warning
light may come on and a chime may sound. See Safety Belt
Warning Light and Chime in the Instrumentation chapter.
