How to Use This Manual
Many people read the owner manual from beginning
to end when they first receive their new vehicle.
If this is done, it can help you learn about the features
and controls for the vehicle. Pictures and words
work together in the owner manual 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. We
use a box and the word CAUTION to tell 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 do not,
you or others could be hurt.
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Do Not,”
“Do Not do this” or
“Do Not let this happen.”
iii

Vehicle Damage Warnings
Also, in this manual you will find these notices:
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. But
the notice will tell 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. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
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.
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
•Audio System(s) in Section 3

Section 1 Seats and Restraint Systems
1-1

Front Seats
Manual Passenger Seat
Your vehicle may have a manual passenger seat. To
adjust the seat, lift the bar under the front of the seat
to unlock it. Slide the seat to where you want it and
release the bar. Try to move the seat back and forth with
your body to be sure the seat is locked in place.
Power Seats
If your vehicle is equipped with power front seats, the
controls are located on the outboard sides of the
front seat cushions.
•Move the front of the horizontal control up or down
to raise or lower the front portion of the cushion.
•Move the rear of the horizontal control up or down
to raise or lower the rear portion of the cushion.
•Lift up or push down on the center of the horizontal
control to move the entire seat up or down.
•To move the seat forward or rearward, slide the
horizontal control forward or rearward.
1-2

Power Lumbar
Your vehicle may have this feature. The driver’s and
passenger’s seatback lumbar support can be adjusted
by moving a control located on the outboard side of
the seat cushions.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your
seating position changes, as it may during long trips,
so should the position of your lumbar support. Adjust
the seat as needed.
Heated Seats
If your vehicle is equipped
with heated front seats, the
buttons are located on
the climate control panel.
There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI
and off. The active setting appears on the climate control
panel display. The LO setting warms the seatback
and cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.
To turn on the heated seats, press the button once.
The seat will heat to the HI setting. Press the button
again to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press
the button again.
1-3

Reclining Seatbacks
If your vehicle has manual reclining front seatbacks,
the levers are located on the outboard sides of the
front seats.
Lift the lever to release the seatback, then move the
seatback to where you want it. Release the lever to lock
the seatback in place. To return the seatback to the
upright position, pull up on the lever without pushing on
the seatback.
If your vehicle has power reclining front seatbacks,
the control is located on the outboard side of the
front seats.
Press the top of the vertical control forward or rearward
to adjust the seatback angle.
Manual Recliner
Power Recliner
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 not do their
job when you are reclined like this.
The shoulder belt can not do its job. In a
crash, you could go into it, receiving neck or
other injuries.
The lap belt can not 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.
1-5

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
The front seat head restraints move up and down.
Press the button located at the bottom of the head
restraint to raise or lower the head restraint. The head
restraints tilt forward and rearward, also.
The rear seat head restraints work the same as the front
head restraints. You can remove the rear head restraints,
also. Press the button located on top of the seatback and
pull up on the head restraint to remove it.
Rear Seats
Split Folding Rear Seat
Your vehicle may have a split folding rear seat. A split
folding rear seat allows you to carry long cargo by
folding down part or all of the rear seat. Before you can
fold the rear seatback, you need to unlatch the center
seatbelt buckle.
1-6

Use the following steps to lower one or both of the rear
seatbacks: 1. Insert a tool with a
small tip into the slot
as shown to unlatch
the seatbelt buckle.
Then move the belt to
the side so it is not
in your way.
2. There is a tab located
on the outboard sides
of the seatback.
Pull forward on the
tab to unlock the
seatback.
3. Fold the seatback down. This will allow you direct
access to the trunk.
4. Repeat Steps 2 and 3 to fold down the other
seatback.
{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
press rearward on the seatback to be sure it is
locked.
{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.
1-7

To return the seatback to the upright position, do the
following:
1. Lift the seatback up and push it back into place.
2. Reconnect the center
safety belt latch plate
to the buckle as
shown.
3. Make sure the seatback is locked into place by
pushing and pulling on it.
4. Repeat Steps 1 and 3 for the other seatback.
When the seatback is not in use, it should be kept in
the upright, locked position.
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 can not
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 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.
1-8

{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 3-38
.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why:
They work .
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 bad 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 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up
does matter...a lot!
1-9

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.
1-10

Get it up to speed. Then stop the vehicle. The rider
does not stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield...
1-11

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.

Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicle after an accident
if I am wearing a safety belt?
A: You could be — whether you are wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you are 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 airbags, why should I have to
wear safety belts?
A: Airbags 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 airbag
system ever offered for sale has required the use of
safety belts. Even if you are in a vehicle that has
airbags, you 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 an
accident — even one that is not your fault — you
and your passengers 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 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
Older Children on page 1-28
or Infants and Young Children on page 1-31 . Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not 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.
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 1-27
.
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.
