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.

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.”

iv

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.

Vehicle Symbols

Your vehicle may be equipped with components and

labels that use symbols instead of text. Symbols,

used on your vehicle, are shown along with the text

describing the operation or information relating to a

specific component, control, message, gage or indicator.

If you need help figuring out a specific name of a

component, gage or indicator reference the following

topics in the Index:

“Engine Compartment Overview”

“Instrument Panel”

“Comfort Controls”

“Audio Systems”

Also see “Warning Lights and Gages” in the Index.

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 a split bench seat,

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

the seat.

Lift the lever to unlock the seat. Using your body, 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 Control (If Equipped)

If your vehicle has a lumbar

adjustment, the knob is

located on the outboard side

of the seat cushion.

To increase or decrease support, turn the knob toward

the front or rear of the vehicle. Operating effort can

be reduced if you lean forward slightly while turning

the knob.

Power Seat(s) (If Equipped)

If your vehicle has a power seat, you can adjust it with

these controls located on the outboard sides of the seats.

Raise or lower the front of the seat cushion by

raising or lowering the forward edge of the

horizontal control.

1-4

Move the seat forward or rearward by moving the

whole horizontal control forward or rearward.

Raise or lower the rear of the seat cushion by raising

or lowering the rear edge of the horizontal control.

Moving the whole horizontal control up or down

raises or lowers the entire seat cushion.

If your vehicle has power reclining seats, you can use

the vertical control to adjust the angle of the seatback.

Move the reclining front seatback rearward or forward

by moving the control toward the rear or the front of the

vehicle. See “Reclining Seatbacks” in the Index for

further information.

Power Lumbar Control (If Equipped)

If your vehicle has this

feature, the four

-way

control is located on the

outboard side of the seat.

To increase or decrease support, press and hold the front

or rear of the control. Let go of the control when the

lower seatback reaches the desired level of support.

You can also reshape the side wing area of the lower

seatback for more lateral support. To increase or

decrease support, press and hold the top or bottom of the

control. Let go of the control when the lower seatback

reaches the desired level of support.

1-5

Memory Seat (If Equipped)

If your vehicle has this

feature, the buttons used to

program and recall the

driver’s seat and recliner

position are located on the

driver’s door trim panel.

It does not store the lumbar or back support positions.

To program the memory seat, do the following:

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

2. Then press the SET button and, within five seconds,

press one of the two numbered buttons on the

memory control.

To recall your setting, put the vehicle in PARK (P) and

press the number you chose.

To program the seat position for a second driver, follow

the preceding steps, but press the other number on the

memory control.

Heated Front Seats (If Equipped)

If your vehicle has this

feature, the button used to

control the driver’s heated

seat is located on the

driver’s door panel. The

button used to control the

passenger’s heated seat is

located on the passenger’s

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 will illuminate for each

heat setting anytime the heated seats are operating.

The ignition must be in RUN for this feature to operate.

The heated front seats will be canceled after the ignition

is turned to OFF. If you still want to use the heated front

seat feature after you restart your vehicle, you will need

to press the heated seat button again.

1-6

Reclining Seatbacks

To adjust the front seatback, lift the manual lever located

on the outboard side of the seat. Release the lever to

lock the seatback where you want it. Lift the lever again

without pushing on the seatback 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.

But don’t have a seatback reclined if your vehicle

is moving.

1-7

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.

Head Restraints

Slide the 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.

1-8

On some models, the head restraints tilt forward and

rearward also.

The rear seat head restraints in your vehicle may be

adjustable. They work the same as the front seat head

restraints, except they do not tilt forward or rearward.

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, lift the lever at the base

of the seat to release the seatback.

The lever is located on the outboard side of the

seat cushion.

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.

1-9

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 do the following:

1. Pull forward on

the release strap

located under the

rear seat cushion.

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 do the following:

1. Push rearward on the seat cushion while pulling up

on the release strap under the seat cushion. Pull the

seat cushion downward until it latches.

2. After pulling the seat cushion down, pull up on it to

make sure it is locked.

Rear Seat (Crew Cab)

The second row rear seat has a 60/40 split seat. Either

side of the rear seat may be folded down to give you

more cargo space.

Before folding the rear seat on the driver’s side, insert

the two buckles into the retainer in the seatback. That

way, the buckles will be out of the way when the seat is

folded and will be available for passengers to use when

the seat is returned to the passenger position. Also, make

sure that nothing is under or in front of the seat and that

the head restraints are completely lowered.

1-10

To fold the rear seat, do the following:

1. Pull up on the strap loop

at the rear of the seat

cushion. Then, pull the

seat cushion up and fold

it forward.

2. After folding the seat cushion fully forward, pull the

seatback forward and fold the seatback down until it

is flat. If the seatback cannot fold flat because it

interferes with the cushion, try moving the front seat

forward and/or bringing the front seat more upright.

The lever at the base of the seat must be turned

rearward to release the seatback.

To return the seat to the passenger position do

the following:

1. Lift the seatback up and push it rearward all the way.

2. Lower the seat cushion until it latches into position.

3. Pull forward on the seatback and up on the seat

cushion to make sure the seat is securely in place.

Check to see that the buckles on the driver’s side

seatback are accessible to the outboard and center

occupant and are not under the seat cushions.

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.

1-11

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.

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.

1-12

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

on wheels.

Put someone on it.

1-13

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

doesn’t stop.

The person keeps going until stopped by something.

In a real vehicle, it could be the windshield ...
