Safety Warnings and Symbols

There are a number of safety cautions in this book. We

use a box and the word CAUTION to tell 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 do not, you or others

could be hurt.

You will also ﬁnd a circle

with a slash through it in

this book. This safety

symbol means “Do Not,”

“Do Not do this” or

“Do Not let this happen.”

iii

Vehicle Damage Warnings

Also, in this manual you will ﬁnd these notices:

Notice: These mean there is something that could

damage your vehicle.

A notice tells about something that can damage the

vehicle. Many times, this damage would not be covered

by your vehicle’s warranty, and it could be costly. But

the notice will tell 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.

There are also warning labels on the vehicle. They use

the same words, CAUTION or NOTICE.

Vehicle Symbols

The vehicle has components and labels that use symbols

instead of text. Symbols 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:

• Seats and Restraint Systems in Section 1

• Features and Controls in Section 2

• Instrument Panel Overview in Section 3

• Climate Controls in Section 3

• Warning Lights, Gages, and Indicators in Section 3

• Audio System(s) in Section 3

• Engine Compartment Overview in Section 5

Section 1 Seats and Restraint Systems

1-2

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.

If your vehicle has a manual bucket or a split bench

seat, you can adjust the seat forward or rearward with

the bar located under the front of the seat cushion.

Lift the bar to unlock the seat. Slide the seat to where you

want it and release the bar. Try to move the seat with

your body to be sure the seat is locked in place.

1-3

Power Seats

If your vehicle has power seats, the controls are located

on the outboard side of the seats.

• Raise or lower the front of the seat cushion by

raising or lowering the front of the horizontal control.

• Raise or lower the rear of the seat cushion by

raising or lowering the rear of the horizontal control.

• Raise or lower the entire seat cushion by raising or

lowering the whole horizontal control.

• Move the seat forward or rearward by moving the

horizontal control forward or rearward.

If your vehicle has power reclining seatbacks, the

control is located rear of the power seat control on the

outboard side of the seats. Adjust the angle of the

seatback by pressing the vertical control forward

or rearward. See Reclining Seatbacks on page 1-6.

If your vehicle has manual reclining seatbacks,

see Reclining Seatbacks on page 1-6.

Power Lumbar

Your vehicle may have this feature.

The control is located on

the outboard side of the

seat cushion.

To increase or decrease support, hold the control

forward or rearward. Keep in mind that as your seating

position changes, as it may during long trips, so

should the position of your lumbar support. Adjust the

seat as needed.

1-4

Heated Seats

If your vehicle has this

feature, the buttons are

located on the front doors.

The engine must be

running for the heated

seats to work.

To heat the entire seat, press the horizontal button with

the heated seat and seatback symbol. Press the button to

cycle through the temperature settings of high, medium

and low and to turn the heated seat off. Indicator lights

will be lit to designate the level of heat selected: three for

high, two for medium, and one for low.

To heat only the seatback, press the vertical button with

the heated seatback symbol. An indicator light on the

seatback button will be lit to designate that only the

seatback is being heated. Additional presses of

the seatback button will cycle through the heat levels for

the seatback only. Press the horizontal button again

to heat the whole seat.

The heated seats will be canceled after the ignition is

turned off. If you still want to use the heated seat feature

after you restart your vehicle, you will need to press

the heated seat button again.

1-5

Reclining Seatbacks

{CAUTION:

If the 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 seatback to be sure it is

locked.

To adjust the seatback, lift the manual lever located on

the outboard side of the seat. Release the lever to

lock the seatback in the desired position. 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 on page 1-4 for further information on

how to operate the reclining seatback feature.

1-6

{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.

Do not have a seatback reclined if your vehicle is

moving.

Head Restraints

Adjust your head restraint 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.

Pull the head restraint up to raise it. Push the head

restraint down to lower it.

Your rear seats may have head restraints that can be

adjusted up and down.

1-7

Seatback Latches

The front seatbacks fold forward to allow access to the

rear of the cab.

To fold the seatback forward, lift the lever located on

the outboard side of the seat cushion.

{CAUTION:

If the 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 seatback to be sure it is

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.

Rear Seats

Rear Seat Operation (Extended Cab)

Folding the Rear Seat

The rear seat in the extended cab can be folded up to

provide more cargo space.

To fold the seat up, do the following:

1. Push down on the front

of the seat cushion

while pulling down on

the release strap

which is located under

the seat cushion.

2. Pull the seat cushion up until it latches with the

seatback.

3. After latching the seat cushion up, pull forward on it

to make sure it is locked.

1-8

The seat can also be folded down for more seating

space.

To fold the seat down, do the following:

1. Push the seat cushion while pulling the release

strap which is located under the seat cushion.

Pull the seat cushion down until it latches.

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

make sure it is locked.

Rear Seat Operation (Crew Cab)

The second row seat is a 60/40 split seat. Either side of

the rear seat may be ﬂipped and folded for added

cargo space.

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

and that the head restraints are completely lowered.

To ﬂip and fold the 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 ﬂip it forward.

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

seatback forward 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.

1-9

To return the seat to the normal seating position, do the

following:

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

{CAUTION:

If the 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 seatback to be sure it is

locked.

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

locked into place.

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

Pull up on the cushion to make sure it is locked into

place.

{CAUTION:

A safety belt that is improperly routed, not

properly attached, or twisted will not provide

the protection needed in a crash. The person

wearing the belt could be seriously injured.

After raising the rear seatback, always check

to be sure that the safety belts are properly

routed and attached, and are not twisted.

Make sure that the safety belt buckles on the driver’s

side seatback are accessible to the outboard and center

occupant and are not under the seat cushions.

1-10

Safety Belts

Safety Belts: They Are 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.

{CAUTION:

Do not let anyone ride where he or she cannot

wear a safety belt properly. If you are in a

crash and you are 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.

1-11

Your vehicle has a light

that comes on as a

reminder to buckle up. See

Safety Belt Reminder

Light on page 3-34.

In most states and in all Canadian provinces, the law

says to wear safety belts. Here is why: They work.

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

a crash, you do not 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 would not

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 is just a seat on

wheels.

1-12

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

does not stop.

1-13

The person keeps going until stopped by something. In

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

or the instrument panel...
