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.”
iii

Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice will 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 has 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:
•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

Front Seats
Manual Seats
The bucket seats can be adjusted forward or rearward
with the lever located at the front of the seat.
To adjust the seat, pull the lever up to release the seat
bottom. Slide the seat to where you want it and then
release the lever. Try to move the seat with your body,
to make sure the seat is locked into place.
{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.
1-3

Power Seat
If your vehicle has a power seat on the driver’s or
passenger’s side, you can adjust it with these controls
located at the front center of the seat cushion.
To raise or lower the seat, move the center knob up or
down. To move the seat forward or rearward, move
the center knob toward the right or left.
To raise or lower the front of the seat cushion, move the
right lever up or down. To raise or lower the rear of
the seat cushion, move the left lever up or down.
Reclining Seatbacks
To adjust the seatback, lift the front of the lever, which
is located on the inboard side of the seat cushion.
Move the seatback with your body and release the lever
to lock the seatback where you want it. Lean forward
and pull up on the front of the lever and the seatback will
go to an upright position.
1-4

But don’t have a seatback reclined if your vehicle is
moving.
{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 because it
won’t be against your body. Instead, it will be
in front of you. 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.

Rear Seats
Rear Seat Operation
Removing the Rear Seat
1. Disconnect the quick
release latch plates for
the lap shoulder belts
on the bench seat to be
removed. To do this,
press the tip of a key
into the release hole of
the safety belt buckle
while pulling up on the
safety belt.
2. Locate the pins.
•There are two pins located on the inboard sides
of the rear seats. If the vehicle has floor mats,
the pins will be located under a flap that has
been cut into the mat. The driver’s side pin will
have an “L” marked on it and will look like this:
1-6

•The passenger’s side pin will have
an “R” marked on it and will look like this:
3. Pull the pin handle up to disengage from the
retaining clip, then pull the pin out.
4. Repeat this procedure for the pin on the other
seat base.
5. Pull the seat rearward about two inches (5 cm) and
then lift the seat from the floor rails.
6. Remove the seat from the vehicle.
7. For the first row rear
seat, stow the safety
belt latch by attaching
the clip on the safety
belt latch to the trim just
inside the side door.
For the remaining rear
seats, stow the safety
belt latch plate on the
clip at the window trim.

Replacing the Rear Seats
{CAUTION:
A seat that isn’t locked into place properly can
move around in a collision or sudden stop.
People in the vehicle could be injured. Be sure
to lock the seat into place properly when
installing it.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won’t 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.
1. Position the seat into the open slots in both rails.
Push the seat forward in the rail, hooking both
seat bases onto the pins inside of the rails.
2. To install the locking pins at the rear of the seat
base, locate the hole in the rail for the pin. It is
found on the inboard side of the seat. If the vehicle
has floor mats, pull the flap that has been cut
into the mat.
3. Insert the locking pin into the seat base and push
the seat to line up with the pin with the base. The
pin with the handle marked “R” must be installed on
the passenger’s side and the pin with the handle
marked “L” on the driver’s side.
1-8

4. Push the pin with the handle marked “R” down until
it is in the retaining clip. 5. Push the pin with the handle marked “L” down until it is in the retaining clip.
6. If the vehicle has a floor mat, put the flap back to
its original position.
7. Repeat this procedure for the other seat base.
8. Connect the quick-release latch plates for the
lap-shoulder belts by inserting the latch plates
into the buckles attached at the outboard positions
of the bench seat. Do not twist the belt.
9. Check that both locking pins are locked into place
before operating the vehicle.

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:
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.
{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 on page 3-28.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why: They work.
1-10

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.
Take the simplest vehicle. Suppose it’s just a seat on
wheels.
1-11

Put someone on it. Get it up to speed. Then stop the vehicle. The rider
doesn’t stop.
1-12

The person keeps going until stopped by something. In
a real vehicle, it could be the windshield... or the instrument panel...
1-13

or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.
Questions and Answers About
Safety Belts
Q: Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A: You could be – whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re upside down. And your chance
of being conscious during and after an accident,
so you can unbuckle and get out, is much greater if
you are belted.
Q: If my vehicle has air bags, why should I have to
wear safety belts?
A: Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they work with
safety belts – not instead of them. Every air bag
system ever offered for sale has required the
use of safety belts. Even if you’re in a vehicle that
has air bags, you still have to buckle up to get
the most protection. That’s true not only in frontal
collisions, but especially in side and other
collisions.
