Safety Restraint Belts Important safety information on how to use seat belts. 1 Safety belts have proven to be the single most effective means available for reducing the potential for either death or personal injury in motor vehicle accidents. 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. 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 observe user warnings pertaining to safety belts. Your vehicle is equipped with a seat belt indicator lamp, located on the face of the tachometer. WARNING Do not adjust the driver's seat while the vehicle is moving.

The seat could move suddenly and unexpectedly and can cause the driver to lose control of the vehicle. Make all adjustments to the seat while the vehicle is stopped. After adjusting the seat and before driving off, always check to ensure that the seat is firmly latched in position. Failure to comply may result in person- al injury, death, equipment or property damage. WARNING Before driving or riding in vehicle, en- sure that there is adequate head clear- ance at maximum upward travel of seat. Injury may occur if head clear- ance is not adequate. Failure to com- ply may result in personal injury or death. Y53-6047-2HEN (03/18) 27
