How to Use This Manual
Many people read the owner manual from
beginning to end when they first receive their
new vehicle. If this is done, it can help you learn
about the features and controls for the vehicle.
Pictures and words work together in the owner
manual to explain things.
Index
A good place to quickly locate information about
the vehicle is the Index in the back of the manual.
It is an alphabetical list of what is in the manual
and the page number where it can be found.
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.”

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

Bucket Seats
If your vehicle has bucket seats, you can adjust
the seats several different ways.
Fore-and-Aft Adjustment
{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 do not want to.
Adjust the driver’s seat only when the
vehicle is not moving.
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

The lumbar adjustment
knob is located on the
seatback, on the
inboard side of the
driver’s seat and on the
outboard side of the
passenger’s seat.
For more support to your lower back, turn the
lumbar adjustment knob clockwise. To decrease
the amount of lumbar support, turn the knob
counterclockwise.
Seatback Adjustment
{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 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.

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

your safety belt properly.

safety belts are properly routed and
attached, and are not twisted.
Notice: Folding a rear seat with the safety
belts still fastened may cause damage to the
seat or the safety belts. Always unbuckle
the safety belts and return them to their normal
stowed position before folding a rear seat.
The rear bench seat on the crew cab can be folded
