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.
Index
A good place to look for what you need is the Index in
back of the manual. It’s an alphabetical list of what’s in
the manual, and the page number where you’ll find it.
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.”

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.

Seats and Seat Controls
This section tells you how to adjust the seats and
explains the reclining seatbacks and head restraints.
Manual Front Seat
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.
2-Way Manual Seat
Lift the bar under the front of the seat using an upward
motion. This will 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 into place.

yellowblue
1-3
6-Way Power Seat (If Equipped)
You may have a six-way power driver’s seat and a
six-way power passenger’s seat (if equipped).
This switch is designed to imitate the movements of
your seat cushion. The driver’s switch is located on the
left side of the driver’s seat cushion. The passenger’s
switch is located on the right side of the passenger’s seat
cushion. To move the seat forward or rearward, push the
switch forward or rearward. To raise or lower the entire
seat, push the switch up or down. To raise or lower the
front portion of your seat, push the front of the switch
up or down. To raise or lower the rear portion of your
seat, push the rear of the switch up or down.
Reclining Front Seatbacks
Lift the lever to release the seatback, then move the
seatback to where you want it. Release the lever to lock
the seatback into place. Pull up on the lever without
pushing on the seatback and the seatback will
move forward.

yellowblue
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.
Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.

Safety Belts: They’re 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.
And it explains the air bag system.
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” in
the Index.)

In most 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.
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.

yellowblue
1-7
Put someone on it. Get it up to speed. Then stop the vehicle. The rider
doesn’t stop.

yellowblue
1-8
The person keeps going until stopped by something.
In a real vehicle, it could be the windshield ...
or the instrument panel ...

yellowblue
1-9
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.
Here Are Questions Many People Ask
About Safety Belts -- and the Answers
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.

1-10
Q: If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A: You may be an excellent driver, but if you’re in an
accident -- even one that isn’t your fault -- you and
your passengers can be hurt. Being a good driver
doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious
injuries and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
Adults
This part is only for people of adult size.
Be aware that there are special things to know about safety
belts and children. And there are different rules for smaller
children and babies. If a child will be riding in your
vehicle, see the part of this manual called “Children.”
Follow those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.

yellowblue
1-11
Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see “Seats” in the Index)
so you can sit up straight.
3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
The shoulder belt may lock if you pull the belt across
you very quickly. If this happens, let the belt go back
slightly to unlock it. Then pull the belt across you
more slowly.
4. Push the latch plate into the buckle until it clicks.

yellowblue
1-12
Pull up on the latch plate to make sure it is secure. If
the belt isn’t long enough, see “Safety Belt
Extender” at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you’d be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of the
body are best able to take belt restraining forces.
The safety belt locks if there’s a sudden stop or crash, or
if you pull the belt very quickly out of the retractor.

yellowblue
1-13
Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
To move it down, squeeze the release lever and the
shoulder belt guide as shown and move the height
adjuster to the desired position. You can move the
adjuster up just by pushing up on the shoulder belt
guide. After you move the adjuster to where you want it,
try to move it down without squeezing the release lever
to make sure it has locked into position.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be away
from your face and neck, but not falling off
your shoulder.

yellowblue
1-14
Q: What’s wrong with this?
A: The shoulder belt is too loose. It won’t give nearly
as much protection this way.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.
