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:
D “Instrument Panel”
D “Comfort Controls”
D “Audio Systems”
Also see “Warning Lights and Gages” in the Index.

These are some examples of vehicle symbols you may find on your vehicle:

conventional cab models as shown. Most models are

Seats and Seat Controls
This section tells you about the seats in your vehicle and
how to adjust them.
CAUTION:
You can lose control of the vehicle if you try
to adjust the 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.
Bucket and Bench Seats
If your vehicle has a bucket or bench seat, you can
adjust it with this lever located at the front of the seat.
Slide the lever toward the outer seat support to unlock it.
Slide the seat to where you want it. Then, release the
lever and try to move the seat with your body to make
sure the seat is locked into place.

1-3
Head Restraints
Some seats have adjustable head restraints. 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
The full-width bench seat seatback folds forward to let
you reach the rear of the cab. Bucket seats have
outboard-mounted levers to tilt the seatbacks forward or
rearward.
Your seatback will move back and forth freely unless
you come to a sudden stop -- then it will lock into place.
The seatback latch is
located on the rear of the
seat cushion. To fold the
seatback forward, pull the
seatback toward the
front of the vehicle
as you lift this latch.
