Safety Warnings and
Symbols
You will find
a
number of safety cautions
in
this book. We
use
a
box with
gray background and the word CAUTION to tell you about things that could
hurt you if you were to ignore the warning.
In
the gray 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 yellow for
cautions, blue for notices and the words CAUTION or NOTICE.
Vehicle

these symbols are used on an original battery:

Seats and Seat Controls
This section tells you about the seats-how to adjust them, and fold them up
and down.
Front Seat (Except Easy Entry)
Move the lever under
the front
of
the seat to
your left 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.
Front Seat (Easy Entry Only)
Move the lever under
the front
of
the seat up
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.
Reclining Front Seatbacks
(Bucket Seats
or
60/40
Bench)
?o
adjust the seatback,
lift the lever on the
outer side
of
the seat.
Release the lever to
lock the seatback
where you want it.
Pull up on the lever
and the seat will go to
an upright position.
But don’t have a seatback reclined if your vehicle is moving.
1-3
Front Seatback Latches
The front seatback folds forward to let people get into the back seat or reach
the storage area behind the seat. Your seatback will move back and forth
freely, unless
you
come
to
a sudden stop. Then
it
will lock in place.
There’s
one
time the seatback may not fold without some help from
you.
That’s if your vehicle is parked going down a fairly steep hill.
To
fold a front
seatback forward,
push the seatback
toward the rear as you
lift this latch. Then the
seatback will fold
forward. The latch
must be down for the
seat to work properly.

Easy
Entry Seat (Exfended
Cab)
The right front bucket or split-bench seat
of
your vehicle makes
it
easy to
get in and out
of
the rear vehicle area.
0
When
you
tilt the right front seatback
fully
forward, the whole seat
will
slide forward.
0
After someone gets into the rear seat area, move
the
right front
seatback to its original position. Then move the seat rearward
until
it
locks.
To
get
out, again tilt the seatback
fully
forward.
Jump
Seat (Extended Cab Models)
STORED POSITION FOLDED-DOWN POSITION
Your extended cab pickup has jump seats in the rear area.
To
fold the jump
seat down, pull down on the handle on the bottom
of
the seat until the seat
is
in place, then move the seatback to a vertical position.
To
store the seat, fold
the seatback down
on
the cushion, then push
the
entire seat up until
it
is
flush with the trim panels.
Don’t let the safety belts be damaged by the hinges
or
the latches. Safety
belts should be folded and stored between the seat cushion and seatback.
Head Restraints
The head restraints in
this vehicle are not
adjustable.

Safety Belts: They’re Fer
;:3.:+Jy:.;
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.
This figure lights up as a reminder to buckle up. (See “Safety Belt Reminder
Light” in the Index.)
In many 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.
1-7
After more than
25
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.
