Safety Restraint Belts
The right and left seats are equipped with 3-point lap/shoul-
der belts; the center seat has a 2-point seat belt. Safety belts
have proven to be the single most effective means available
for reducing the potential for either serious injury or death in
motor vehicle accidents. Therefore, read and follow these
instructions and always observe user warnings pertaining to
safety belts.
WARNING! Do not drive vehicle without your
seat belt and your riders’ belts fastened. Riding
without a safety belt which is properly fastened
can lead to increased injury or death in an acci-
dent. Unbelted riders could be thrown into the
windshield or other parts of the cab or could be
thrown out of the cab. They could strike another
person. Injuries can be much worse when riders
are unbelted. Always fasten your seat belt and
be sure anyone riding with you does the same.
Lap/Shoulder Belt
The combination lap-shoulder belt is equipped with a locking
mechanism. The system adjusts automatically to a person’s
size and movements as long as the pull on the belt is slow.
Hard braking or a collision locks the belt. The belt will also
lock when driving up or down a steep hill or in a sharp curve.
To fasten the belt:
1. Grasp the belt tongue.
2. Pull the belt in a continuous slow motion across your
chest and lap.
