Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down.
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 a manual seat up to
unlock it. Slide the seat to where you want it and release
the lever. 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 your vehicle has this
feature, there will be a knob
located on the outboard side
of the driver's seat.
Turn the knob counterclockwise to increase lumbar
support and clockwise to decrease lumbar support.
Power Seats (If Equipped)
If your vehicle has this feature, there will be a control on
the outboard side of the front seat(s).

1-4
Horizontal Control: Raise or lower the front of the seat
by raising or lowering the forward edge of the control.
Raise or lower the rear of the seat by raising or lowering
the rear edge of the control. Move the seat forward or
rearward by moving the whole control toward the front
or the rear of the vehicle.
Moving the whole control up or down raises or lowers
the whole seat.
Vertical Control: Move the reclining front seatback
forward or rearward by moving the control toward the
front or rear of the vehicle.Power Lumbar Control (If Equipped)
If your vehicle has this
feature, there will be a
control located on the
outboard side of the
front seat(s).
Press and hold the front of the control until you have the
desired lumbar support. To decrease lumbar support,
press and hold the rear of the control.

1-5 Memory Seat (If Equipped)
If your vehicle has this
feature, the control, located
on the outboard side of the
driver's seat, looks like this.
Use this memory function to save your seat cushion and
seatback settings by using the following procedure:
1. Adjust the driver's seat to a safe and comfortable
driving position.
2. Press the SET button and then press and hold button 1
(for driver) for three seconds. A chime will sound to
let you know that the position has been stored.
A second seating and mirror position can be
programmed by repeating the procedure with a second
driver and pressing button 2 for three seconds. Each
time button 1 or 2 is pressed and released while the
vehicle is in PARK (P), the memory position will be
recalled. Each time a memory button is pressed, a
single chime will sound.3. To program your keyless entry transmitter, if
equipped, press the UNLOCK button within five
seconds of programming the memory button. You
will hear a chime to confirm programming of the
transmitter.
When your vehicle is in PARK (P) for an automatic
transmission or the parking brake is engaged for a
manual transmission, push and release the numbered
memory button you just stored. The seat will move to
the set position. You will hear one chime.
Pressing the UNLOCK button of a keyless entry
transmitter will adjust the seat to the corresponding
stored memory position. You will hear one chime.
Repeat Steps 1 and 2 to readjust the seat. The transmitter
need not be programmed unless it needs to correspond
to the other numbered memory button.
If there is a third driver, use the seat adjuster switch
to adjust the seat. Pressing any of the seat adjuster
switches, the SET button or pressing the desired
memory button twice will cause the seat to stop moving.
If you push the numbered button to adjust the seat and
start the vehicle while the seat is still adjusting,
adjustment will pause while the ignition is in START.
Adjustment will resume after the ignition is in RUN.

1-6 Heated Front Seats (If Equipped)
If your vehicle has this
feature, the controls are
located on the outboard
side of the front seats.
This feature will quickly heat the seat cushion and lower
back of the driver's and front passenger's seats for
added comfort.
Press the lower part of the control to turn the heater on
low. Press the upper part of the control to turn the heater
on high. Move the control to the center position to turn
the heater off.
The passenger's safety belt must be engaged for the
heated seat feature to work on the passenger's seat.
Reclining Seatbacks
If your vehicle is equipped with power seats, see ªPower
Seatsº earlier in this section for information on reclining
the seatback.
To adjust a manual
front seatback, lift the
lever on the outboard side
of the seat.
Release the lever to lock the seatback where you want it.
Pull up on the lever without pushing on the seatback and
the seat will go to an upright position.

1-7
But don't have a seatback reclined if your vehicle is
moving.
CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can't do their job when
you're reclined like this.
The shoulder belt can't do its job because it
won't be against your body. Instead, it will be in
front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt can't do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.

1-8 Head Restraints
Head restraints are fixed on some models and adjustable
on others. Slide an adjustable head restraint up or down
so that the top of the restraint is closest to the top of
your head. This position reduces the chance of a neck
injury in a crash.
Seatback Latches (Regular or Extended
Cab Only)
The front seatback folds forward to let people get into
the rear seat or to access the storage area behind the seat.
To fold the front
seatback forward,
push the lever on
the side of the seat
rearward and pull the
seatback forward.

1-9
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 (If Equipped)
The right front bucket or split-bench seat on some
models makes it easy to get in and out of the rear
vehicle area.
1. Tilt the right front seatback completely forward and
the whole seat will slide forward.
2. Return the seatback to its original position after
someone gets into the rear seat area. Then move the
seat rearward until it locks.
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 and slide the seat completely forward
again to get out of the rear vehicle area.
