All seating positions in the vehicle have a lap-shoulder belt.
The following instructions explain how to wear a lap-shoulder belt properly.
Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats” in the Index. Pick up the latch plate and pull the belt across you. Do not let it get twisted.
