Using this Manual
Safety Warnings and Symbols
Many people read the owner manual from beginning to
end when they first receive their new vehicle to learn
about the vehicle’s features and controls. Pictures
and words work together 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.
There are a number of safety cautions in this book. A
box with the word CAUTION is used to tell about things
that could hurt you or others if you were to ignore the
warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
We tell you what the hazard is and what to do to help
avoid or reduce the hazard. Please read these cautions.
If you do not, you or others could be hurt.
A circle with a slash
through it is a safety
symbol which means “Do
Not,” “Do Not do this”
or “Do Not let this happen.”
iii
Vehicle Damage Warnings
Vehicle Symbols
You will also find notices in this manual.
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.
The notice tells 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 which use
the same words, CAUTION or NOTICE.
iv
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.

Reclining Seatbacks
Manual Reclining Seatbacks
{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 seats have manual reclining seatbacks, the lever
used to operate them is located on the outboard
side of the seats.
{CAUTION:
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.

1-8
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job. In a 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 in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.
Do not have the seatback reclined if your vehicle is
moving.
1-9
Head Restraints
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant’s
head. This position reduces the chance of a neck injury
in a crash.
Pull the head restraint up
to raise it.
To lower the head restraint, press the button, located
on the top of the seatback, and push the head
restraint down.
1-10
Center Seat
Your vehicle may have a front center seat. This seat
can be converted to a storage area by lowering
the seatback. See Center Flex Storage Unit on
page 2-57.
Rear Seats
Rear Seat Pass-Through Door
Your vehicle has a pass-through door that provides
access to the trunk from the rear seats. See “Rear Seat
Pass-Through Door” under Trunk on page 2-13.
1-11
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:
Do not let anyone ride where he or she cannot
wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle harder or be ejected
from it and 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 passenger(s) are
restrained 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 indicators as a reminder to buckle your
safety belts. See Safety Belt Reminders on page 3-34.
In most states and in all Canadian provinces, the
law requires wearing safety belts. Here is why:
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a serious one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person would not survive.
But most crashes are inbetween.Inmanyofthem,people
who buckle up can survive and sometimes walk away.
Without belts they could have been badly hurt or killed.
After more than 40 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter... a lot!
1-12
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it is just a seat on
wheels.
Put someone on it.
1-13
Get it up to speed. Then stop the vehicle. The rider
does not stop.
1-14
The person keeps going until stopped by something.
In a real vehicle, it could be the windshield...
or the instrument panel... 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 is why
safety belts make such good sense.
1-15
Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicle after a crash if
I am wearing a safety belt?
A: You could be — whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so you can unbuckle
and get out, is much greater if you are belted.
And you can unbuckle a safety belt, even if you are
upside down.
Q: If my vehicle has airbags, why should I have to
wear safety belts?
A: Airbags are supplemental systems only; so they
work with safety belts — not instead of them.
Whether or not an airbag is provided, all occupants
still have to buckle up to get the most protection.
That is true not only in frontal collisions, but
especially in side and other collisions.
Q: If I am 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 are in a
crash — even one that is not your fault — you and
your passenger(s) can be hurt. Being a good
driver does not 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.
1-16
How to Wear Safety Belts Properly
This section 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 Older Children on page 1-33
or Infants and Young Children on page 1-36. Follow
those rules for everyone’s protection.
It is very important for all occupants to buckle up.
Statistics show that unbelted people are hurt more often
in crashes than those who are wearing safety belts.
Occupants who are not buckled up can be thrown out of
the vehicle in a crash. And they can strike others in
the vehicle who are wearing safety belts.
First, before you or your passenger(s) wear a safety
belt, there is important information you should know.
Sit up straight and always keep your feet on the floor in
front of you. 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 would be less likely to slide under the lap belt.
If you slid under it, the belt would apply force on
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 shoulder belt locks if there is a sudden stop or crash.
1-17
Q: What is wrong with this?
A: The shoulder belt is too loose. It will not 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 snugly against
your body.
1-18
Q: What is wrong with this?
A: The lap belt is too loose. It will not give as much
protection this way.
{CAUTION:
You can be seriously hurt if your lap belt is too
loose. In a crash, you could slide under the lap
belt and apply force on your abdomen. This
could cause serious or even fatal injuries. The
lap belt should be worn low and snug on the
hips, just touching the thighs.
1-19
Q: What is wrong with this?
A: The belt is buckled in the wrong place.
{CAUTION:
You can be seriously injured if your belt is
buckled in the wrong place like this. In a crash,
the belt would go up over your abdomen. The
belt forces would be there, not on the pelvic
bones. This could cause serious internal
injuries. Always buckle your belt into the
buckle nearest you.
1-20
Q: What is wrong with this?
A: The belt is over an armrest.
{CAUTION:
You can be seriously injured if your belt goes
over an armrest like this. The belt would be
much too high. In a crash, you can slide under
the belt. The belt force would then be applied
on the abdomen, not on the pelvic bones, and
that could cause serious or fatal injuries. Be
sure the belt goes under the armrests.
1-21
Q: What is wrong with this?
A: The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
{CAUTION:
You can be seriously injured if you wear the
shoulder belt under your arm. In a crash, your
body would move too far forward, which would
increase the chance of head and neck injury.
Also, the belt would apply too much force to
the ribs, which are not as strong as shoulder
bones. You could also severely injure internal
organs like your liver or spleen. The shoulder
belt should go over the shoulder and across
the chest.
1-22
Q: What is wrong with this?
A: The belt is behind the body.
{CAUTION:
You can be seriously injured by not wearing
the lap-shoulder belt properly. In a crash, you
would not be restrained by the shoulder belt.
Your body could move too far forward
increasing the chance of head and neck injury.
You might also slide under the lap belt. The
belt force would then be applied right on the
abdomen. That could cause serious or fatal
injuries. The shoulder belt should go over the
shoulder and across the chest.
1-23
Q: What is wrong with this?
A: The belt is twisted across the body.
{CAUTION:
You can be seriously injured by a twisted belt.
In a crash, you would not have the full width of
the belt to spread impact forces. If a belt is
twisted, make it straight so it can work
properly, or ask your dealer/retailer to fix it.
1-24
Lap-Shoulder Belt
All seating positions in your vehicle have a lap-shoulder
except for the center front passenger position (if
equipped), which has a lap belt. See Lap Belt on
page 1-31 for more information.
Here is how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-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.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let the
belt go back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system. See
Passenger Sensing System on page 1-67.
1-25
3. Push the latch plate into the buckle until it clicks.
If you find that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, see Safety
Belt Extender on page 1-32.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash. See
“Shoulder Belt Height Adjustment” later in this
section.
5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the
lap belt on smaller occupants.
