How to Use this Manual

Many people read their owner’s manual from beginning

to end when they first receive their new vehicle. If you

do this, it will help you learn about the features and

controls for your vehicle. In this manual, you’ll find

that pictures and words work together to explain

things quickly.

Index

A good place to look for what you need is the Index in

back of the manual. It’s an alphabetical list of what’s in

the manual, and the page number where you’ll find it.

Safety Warnings and Symbols

You will find a number of safety cautions in this book.

We use a box and the word CAUTION to tell you

about things that could hurt you if you were to ignore

the warning.

CAUTION:

These mean there is something that could hurt

you or other people.

In the caution area, we tell you what the hazard is. Then

we tell you what to do to help avoid or reduce the

hazard. Please read these cautions. If you don’t, you or

others could be hurt.

You will also find a circle

with a slash through it in

this book. This safety

symbol means “Don’t,”

“Don’t do this” or “Don’t

let this happen.”

Vehicle Damage Warnings

Also, in this book you will find these notices:

NOTICE:

These mean there is something that could

damage your vehicle.

In the notice area, we tell you about something that can

damage your vehicle. Many times, this damage would

not be covered by your warranty, and it could be costly.

But the notice will tell you what to do to help avoid

the damage.

When you read other manuals, you might see

CAUTION and NOTICE warnings in different colors or

in different words.

You’ll also see warning labels on your vehicle. They use

the same words, CAUTION or NOTICE.

Seats and Seat Controls

This section tells you about the seats -- how to adjust

them, and fold them up and down. It also tells you about

reclining front seatbacks and head restraints.

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.

If your vehicle has a manual bucket or split bench seat,

you can adjust it with this lever located at the front of

the seat.

Lift the lever at the front of the seat to unlock it. Using

your body, slide the seat to where you want it. Then,

release the lever and try to move the seat with your body

in order to make sure the seat is locked into place.

Power Seat(s) (If Equipped)

Horizontal Control: If your vehicle has a power seat,

you can adjust it with this control located at the outside

edge of the seat.

Raise the front of the seat cushion by raising the forward

edge of the button. Lower the front of the seat cushion

by lowering the forward edge of the button. Move the

reclining seats, you can use this button to adjust the

angle of the seatback. Move the reclining front seatback

rearward by moving the button toward the rear of the

vehicle. Move the seatback forward by moving the

button toward the front of the vehicle. See “Reclining

Seatbacks” in the Index for further information.

Memory Seat (If Equipped)

The memory function

controls the driver’s

seat cushion and

recliner positions.

It does not store the lumbar or back support positions.

To set your memory seat:

1. Adjust the driver’s seat to your desired position.

2. Press the SET button and then press the 1 or 2 button

of the memory control within five seconds.

When your vehicle is in PARK (P), press the 1 or 2 side

of the memory control to recall the seat setting.

To do the same thing for a second driver, follow the

preceding steps, but press the other number of the

memory control.

yellowblue

1-7

Heated Front Seats (If Equipped)

If your vehicle has heated

front seats, the ignition must

be in RUN for them

to operate.

The control for the driver’s side heated seat is located on

the driver’s side door panel. The control for the

passenger’s side heated seat is located on the

passenger’s side door panel.

To activate the heated seats, press the button once for

the HI heat setting. Press the button again for the LO

heat setting. To turn off the heated seats, press the button

a third time. An indicator light on the control will

illuminate for each heat setting anytime the heated seats

are operating.

Reclining Seatbacks

To adjust the front seatback, lift the lever upward.

Release the lever to lock the seatback where you want it.

Lift the lever again upward and the seatback will go to

an upright position.

If your vehicle has power seats with a power recliner,

see “Power Seats” in the Index for further information

on how to operate the reclining seatback feature.

yellowblue

1-8

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. 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.

yellowblue

1-9

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.

On some models, the head restraints tilt forward and

rearward also.

To tilt the head restraints forward, grasp the top of the

restraint and move it forward to where you want it to go

until you hear a click. It will then be locked into that

position until you need to move it again. Pulling it

forward past the last position will allow the restraint to

return to its upright position.

Seatback Latches

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.

The seatbacks fold forward to let you access the rear of

the cab.

To fold a front 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.

yellowblue

1-10

Easy Entry Seat (Extended Cab Only)

CAUTION:

If any easy entry seat isn’t locked, it can move. In

a sudden stop or crash, the person sitting there

could be injured. And, even if there is no crash or

sudden stop, a driver sitting in an unlocked easy

entry seat could be startled by the sudden

movement and hit the wrong control or pedal,

causing an accident. After you’ve used it, be sure

to push rearward on any easy entry seat to be

sure it is locked.

The manual driver side front bucket seat and the manual

driver side split bench seat of your vehicle have an easy

entry feature. This makes it easy to get in and out of the

rear seat.

To operate the seat, pull

forward on the top of this

lever and tilt the seatback

forward toward the front of

the vehicle.

When you do, the seat bottom will release. Just pull or

push the seat forward until it stops.

To return the seat to its regular position, return the

seatback to its upright position, then push the whole seat

rearward until it latches.

After returning the seat to its regular position, try to

move the seat with your body in order to make sure the

seat is locked into place.

1-11

Rear Seat (Extended Cab)

Folding the Rear Seat

The extended cab’s rear seat can be folded up to provide

more cargo space. To fold the seat:

1. Pull forward on the

release strap under the

rear seat cushion, on the

passenger’s side.

2. Fold the seat cushion upward until it latches with

the seatback.

3. Push and pull on the seat

to make sure the seat

is secure.

The extended cab’s rear seat can also be folded open for

more seating space. To use the seat:

1. Push rearward on the seat cushion while pulling up

on the release strap under the seat cushion, located

on the passenger’s side of the rear seat. Pull the seat

cushion downward until it latches.

2. After pushing the seat cushion downward, pull up on

the seat cushion to make sure it is locked.

Safety Belts: They’re for Everyone

This part of the manual tells you how to use safety belts

properly. It also tells you some things you should not do

with safety belts.

And it explains the air bag system.

CAUTION:

Don’t let anyone ride where he or she can’t wear

a safety belt properly. If you are in a crash and

you’re not wearing a safety belt, your injuries

can be much worse. You can hit things inside the

vehicle or be ejected from it. You can be seriously

injured or killed. In the same crash, you might

not be if you are buckled up. Always fasten your

safety belt, and check that your passengers’ belts

are fastened properly too.

CAUTION:

It is extremely dangerous to ride in a cargo area,

inside or outside of a vehicle. In a collision,

people riding in these areas are more likely to be

seriously injured or killed. Do not allow people to

ride in any area of your vehicle that is not

equipped with seats and safety belts. Be sure

everyone in your vehicle is in a seat and using a

safety belt properly.

Your vehicle has a light

that comes on as a reminder

to buckle up. (See “Safety

Belt Reminder Light” in

the Index.)

In most states and Canadian provinces, the law says to

wear safety belts. Here’s why: They work.

yellowblue

1-13

You never know if you’ll be in a crash. If you do have a

crash, you don’t know if it will be a bad one.

A few crashes are mild, and some crashes can be so

serious that even buckled up a person wouldn’t survive.

But most crashes are in between. In many of them,

people who buckle up can survive and sometimes walk

away. Without belts they could have been badly hurt

or killed.

After more than 30 years of safety belts in vehicles,

the facts are clear. In most crashes buckling up does

matter ... a lot!

Why Safety Belts Work

When you ride in or on anything, you go as fast as

it goes.

Take the simplest vehicle. Suppose it’s just a seat

on wheels.

1-14

Put someone on it. Get it up to speed. Then stop the vehicle. The rider

doesn’t stop.
