Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle is
moving. The sudden movement could startle and
confuse you, or make you push a pedal when you
don't want to. Adjust the driver's seat only when
the vehicle is not moving.
Move the lever under the front of the manual seat up to
unlock it. Slide the seat to where you want it. Then
release the lever and try to move the seat with your body
to make sure the seat is locked into place.

1-3 Manual Lumbar Support (If Equipped)
If you have this feature,
there will be a knob on the
outside of the driver and
passenger bucket seats.
Turn the knob toward the front of the vehicle to increase
lumbar support and toward the rear of the vehicle to
decrease lumbar support.
Reclining Seatbacks
(Bucket Seats or 60/40 Bench)
To adjust the front seatback,
lift the lever on the outer
side of the seat.
Release the lever to lock the seatback where you
want it. Pull up on the lever and the seat will go to an
upright position.

1-5 Seatback Latches
The front seatback folds
forward to let people get
into the back seat or to
access the storage area
behind the seat.
To fold the front seatback forward, turn the handle on the
side of the seat rearward and pull the seatback forward.
To return the seatback to the upright position, push the
seatback all the way back until the latch catches. If the
seatback was reclined before being folded forward, it
will return to the reclined position.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.
Easy Entry Seat (Extended Cab Models)
The right front bucket or split-bench seat of your vehicle
makes it easy to get in and out of the rear vehicle area.

Tilt the right front seatback completely forward and
the whole seat will slide forward.

Move the seatback to its original position after
someone gets into the rear seat area. Then move the
seat rearward until it locks.

1-6
CAUTION:
If an easy entry right front seat isn't locked, it
can move. In a sudden stop or crash, the person
sitting there could be injured. After you've used
it, be sure to push rearward on an easy entry seat
to be sure it is locked.

Tilt the seatback completely forward again
to get out.
Jump Seat (Extended Cab Models)
Your extended cab pickup
has a jump seat in the
rear area.
To fold the jump seat down, pull down on the pull tab on
the bottom of the seat until the seat is in place, then
move the seatback to a vertical position. To store the
seat, fold the seatback down on the cushion, then push
the entire seat up until it is flush with the trim panel.
Don't let the safety belts be damaged by the hinges or
the latches. Safety belts should be folded and stored
between the seat cushion and seatback.
