Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Seatback Latches
The front seatback of the base level bench seat folds
forward to let you access the rear of the cab. Your
seatback will move back and forth freely, unless you
come to a sudden stop. Then it will lock into place. If
you have a Crew Cab, your front seatback is designed
not to fold forward. Access to the rear of the cab is
available by using the rear doors.
The front seatback of the split bench seat and bucket
seats fold forward to let you access the rear of the cab.
To fold a front split bench
or bucket seatback forward,
pull this lever forward and
fold the seatback forward.
To return the seatback to the upright position, just push
the seatback rearward until it latches. After returning the
seatback to its upright position, pull the seatback
forward to make sure it is locked.
CAUTION:
If the seatback isn’t locked, it could move forward
in a sudden stop or crash. That could cause injury
to the person sitting there. Always press rearward
on the seatback to be sure it is locked.
