Rear Seat Passengers (Extended Cab Jump Seats) Rear passengers who aren't safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts. Lap Belt These are reserve seating positions equipped with lap belts only. (If your extended cab pickup has the optional side access panel, there's only one reserve seating position.) It's very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Each jump seat has a lap belt with no retractor. To make the belt longer, tilt the latch plate and pull it along the belt. 1-36
