Sit up straight and always keep your feet on the floor
in front of you. The lap part of the belt should be
worn low and snug on the hips, just touching the thighs.In a crash, this applies force to the strong pelvic bones
and you would be less likely to slide under the lap belt.
If you slid under it, the belt would apply force on your
abdomen. This could cause serious or even fatal
injuries. The shoulder belt should go over the shoulder
and across the chest. These parts of the body are best
able to take belt restraining forces.
The shoulder belt locks if there is a sudden stop or
crash.

Lap-Shoulder Belt
If the vehicle is a regular cab, then all seating positions
in the vehicle have a lap-shoulder belt. If the vehicle is
a crew or extended cab, then all seating positions in the
vehicle have a lap-shoulder belt except for the center
front passenger position (if equipped), which has a lap
belt. SeeLap Belt (Crew and Extended Cab)
on
page 2‑37for more information.
The following instructions explain how to wear a
lap-shoulder belt properly. 1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats”in the
Index.
2. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a passenger belt is pulled
out all the way, the child restraint locking feature
may be engaged. If this happens, let the belt go
back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system, if equipped.

Passenger Sensing System
on page 2‑85for
