Using this Manual
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.
Safety Warnings and Symbols
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

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.
Vehicle Symbols

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.
{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.

{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 because it
will not 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 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 a seatback reclined if your vehicle is
moving.
1-6

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
restraint down.
1-7

Center Seat
Your vehicle may have a front center seat. There are
cupholders on the underside of the seat cushion.
To use them, flip the seat cushion forward. This seat
can also be used as a storage area by lowering
the seatback. See Center Console Storage on
page 2-48. The seatback doubles as an armrest for
the driver or front passenger when the center seat is
unoccupied.
Rear Seats
Split Folding Rear Seat
Flip and Fold Feature
If your vehicle has this feature, you can flip the bottom
seat cushion(s) forward and fold the seatback(s)
down for an extended flat cargo area.
To use this feature:
1. Flip the bottom seat cushion forward by pulling up
on the tab located in the center of the seat cushion
where the seatback meets the seat cushion.
There is a tab on both rear seats.
Make sure the front seats are not reclined. If they
are, the seat cushion will not flip forward completely.
1-8

2. Lower the seatback(s)
by pulling forward on
the tab located on
the outboard side of the
seatback(s).
Make sure the front seats are not reclined. If they
are, the rear seatbacks will not fold down all the way.
To return the seats to the normal position:
{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. Raise the seatback up and make sure it latches.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not 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.
2. Ensure that the safety belts are properly stowed
over the seatback in all three positions.
3. Flip the bottom seat cushion back into place. Push
firmly on the seat cushion to make sure it is secure.
When the seat is not in use, the seatback should
be placed in upright, locked position, and the seat
cushion should be in the down position.
Under Seat Storage
Your vehicle has under seat storage.
To get to the storage area, lift up on the tab located in
the center of the bottom seat cushion where the
seat cushion meets the seatback. See Rear Storage
Area on page 2-48 for more information.

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 3-30.
1-10

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 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 40 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 is just a seat
on wheels.
1-11

Put someone on it. Get it up to speed. Then stop the vehicle. The rider
does not 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 is why
safety belts make such good sense.
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.
1-14

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.
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 1-31
or Infants and Young Children on page 1-34. 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.
1-15

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.
