the same words, CAUTION or Notice.

Head Restraints

The front seats have adjustable head restraints in the

outboard seating positions.

{ CAUTION:

With head restraints that are not installed and

adjusted properly, there is a greater chance that

occupants will suffer a neck/spinal injury in a

crash. Do not drive until the head restraints for all

occupants are installed and adjusted properly.

Adjust the head restraint so that the top of the restraint is

at the same height as the top of the occupant’s head.

This position reduces the chance of a neck injury in a

crash.

1-3

Pull the head restraint up to raise it. To lower the head

restraint, press the button, located on the top of the

seatback, and push the restraint down.

Push down on the head restraint after the button is

released to make sure that it is locked in place.

The head restraints are not designed to be removed.

The rear seat has head rests that can be adjusted

up and down.

Front Seats

Manual Seats

{ 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

do not want to. Adjust the driver’s seat only when

the vehicle is not moving.

1-4

If the vehicle has a manual seat, it can be moved

forward or rearward.

1. Lift the bar to unlock

the seat.

2. Slide the seat to the

desired position and

• Raise or lower the rear part of the seat cushion by

moving the rear of the control up or down.

• Raise or lower the entire seat by moving the entire

control up or down.

On seats with power reclining seatbacks, the control is

located behind the power seat control on the outboard

side of the seats. See “Power Reclining Seatbacks”

under Reclining Seatbacks on page 1-10.

A vehicle with a memory function allows seat settings to

be saved and recalled. See Memory Seat, Mirrors,

and Pedals on page 1-8 for more information.

Manual Lumbar

On vehicles with this feature the control is located on

the outboard side of the seat.

Increase or decrease lumbar support by turning the

knob forward or rearward.

On seats with power lumbar, the controls used to operate

this feature are located on the outboard side of the seats.

• To increase lumbar support, press and hold the front

information.

Keep in mind that as your seating position changes,

as it may during long trips, so should the position of

restarting the vehicle, press the heated seat or seatback

button again.

Memory Seat, Mirrors, and Pedals

Your vehicle may have the memory package.

The controls for this feature

are located on the driver’s

door panel, and are used to

program and recall memory

settings for the driver’s

seat, outside mirrors, and

the adjustable throttle and

brake pedal.

To save seating positions in memory:

1. Adjust the driver’s seat, including the seatback

recliner and lumbar, both outside mirrors, and the

throttle and brake pedals to a comfortable position.

See Outside Power Mirrors on page 2-58 and

for more information.

Not all mirrors, adjustable throttles and brake pedals,

recall their positions.

2. Press and hold button 1 until two beeps sound to

indicate that the position has been stored.

1-8

A second seating, lumbar, mirror, and throttle and brake

pedal position can be programmed by repeating the

above steps and pressing button 2.

To recall the memory positions, the vehicle must be in

PARK (P). Press and release either button 1 or button 2

corresponding to the desired driving position. The seat,

outside mirrors, and adjustable throttle and brake pedals

will move to the position previously stored. You will hear a

single beep.

If you use the remote keyless entry transmitter to enter

your vehicle and the remote recall memory feature is on,

automatic seat, adjustable mirror, and adjustable pedal

movements will occur. See “MEMORY SEAT RECALL”

under DIC Vehicle Customization (With DIC Buttons) on

page 3-75 for more information.

To stop recall movement of the memory function at any

time, press one of the power seat controls, memory

buttons, power mirror buttons, or adjustable pedal switch.

If something has blocked the driver’s seat and/or the

adjustable pedals while recalling a memory position, the

driver’s seat and/or the adjustable pedals recall may stop

working. If this happens, remove the obstruction and

press the appropriate control for the area that is not

responding for two seconds. Try recalling the memory

position again by pressing the appropriate memory

button. If the memory position is still not recalling, see

your dealer for service.

Easy Exit Seat

The control for this feature is located on the driver’s

door panel between buttons 1 and 2.

position can be recalled by pressing the exit button.

You will hear a single beep, and the driver’s seat

will move back.

If the easy exit seat feature is programmed in the Driver

Information Center (DIC), automatic seat movement

will occur when the key is removed from the ignition.

See “EASY EXIT SEAT” under DIC Vehicle

Customization (With DIC Buttons) on page 3-75 for

more information.

The memory seat and easy exit features can also be

programmed using the DIC.

Customization (With DIC Buttons) on page 3-75.

1-9

Reclining Seatbacks

{ 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

do not want to. Adjust the driver’s seat only when

the vehicle is not moving.

{ CAUTION:

If either seatback is not locked, it could move

forward in a sudden stop or crash. That could

cause injury to the person sitting there. Always

push and pull on the seatbacks to be sure they

are locked.

1-10

{ CAUTION:

Sitting in a reclined position when your vehicle is

in motion can be dangerous. Even if you buckle

up, your safety belts cannot do their job when you

are reclined like this.

The shoulder belt cannot do its job. In a crash, you

could go into it, receiving neck or other injuries.

The lap belt cannot 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.

1-11

Manual Reclining Seatbacks

On seats with manual reclining seatbacks, the lever

used to operate them is located on the outboard side

of the seat(s).

To recline the seatback:

1. Lift the recline lever.

2. Move the seatback to the desired position, then

release the lever to lock the seatback in place.

3. Push and pull on the seatback to make sure it is

locked.

To return the seatback to an upright position, do the

following:

1. Lift the lever fully without applying pressure to the

seatback and the seatback will return to the upright

position.

2. Push and pull on the seatback to make sure it is

locked.

1-12

Power Reclining Seatbacks

If the seats have power reclining seatbacks, the control

used to recline them is located on the outboard side

of the seat behind the power seat control.

• To recline the seatback, tilt the top of the control

rearward.

• To bring the seatback forward, tilt the top of the

control forward.

Do not have a seatback reclined if your vehicle is moving.

Seatback Latches

The front seatbacks tilt forward to allow access to the

rear of the cab.

To tilt the seatback forward, lift the lever located on the

outboard side of the seat cushion.

{ CAUTION:

If either seatback is not locked, it could move

forward in a sudden stop or crash. That could

cause injury to the person sitting there. Always

push and pull on the seatbacks to be sure they

are locked.

To return the seatback to the upright position, push the

seatback rearward until it latches. After returning the

seatback to its upright position, push and pull on

the seatback to make sure it is locked.

Center Seat

Your vehicle may have a front center seat. The seatback

doubles as an armrest and cupholder/storage area for the

driver and passenger when the center seat is not used.

Do not use it as a seating position when the seatback is

folded down.

1-13
