Rear Seats
The rear seat has adjustable
headrests in the outboard seating
positions.

down on the headrest.
Rear outboard headrests are not
designed to be removed.

{WARNING
You can lose control of the

the vehicle is not moving.
To adjust the seat:
1. Lift the bar under the front edgeof the seat cushion to unlock
the seat.
2. Slide the seat to the desired position and release the bar.
3. Try to move the seat back and forth to be sure the seat is
locked in place.
Center Seat

seatback doubles as an armrest and
cupholder/storage area for the driver

Seats and Restraints 3-15
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. SeeHow
to Wear Safety Belts Properly on
page 3‑12.
Regular and Crew Cab
To move the adjuster down for the
regular and crew cabs, squeeze the
buttons (A) on the sides of the
height adjuster and move the height
adjuster to the desired position.
