Using this Manual
You should read this owner manual from beginning to
end when you first receive the 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
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.
Vehicle Symbols

Front Seats
Manual Seats
{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.
Lift the bar located 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 with your body to be sure
the seat is locked in place.
1-2

Power Seat The driver’s seat power control is located on the
outboard side of the seat.
To adjust the seat, do any of the following:
•Move the seat forward or rearward by sliding the
control forward or rearward.
•Raise or lower the front part of the seat cushion by
moving the front of the control up or down.
•Raise or lower the rear part of the seat cushion by
moving the rear of the control up or down.
•Raise or lower the entire seat by moving the entire
control up or down.

Power Lumbar
Your driver’s seat may have power lumbar. The control
is located on the outboard side of the seat cushion.
Press the control forward to increase lumbar support.
Press the control rearward to decrease lumbar support.
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 the vehicle has this
feature, the buttons are
located on the climate
control panel. See Climate
Control System on
page 3-28 for more
information.
Press the button once to activate the high heat setting.
Both indicator lights next to the button will come on.
Press the button again to select the lower temperature
setting. Only the bottom indicator light will come on.
Press the button a third time to turn the heat off.
This feature only works when the ignition is on.

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.
{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.
The seats have manual reclining seatbacks. The lever
used to operate them is located on the outboard side of
the seats.
To recline the seatback, do the following:
1. Lift the recline lever.
2. Move the seatback to the desired position, then
release the lever to lock the seatback in place.
3. Push and pull on the seatback to make sure it is
locked.

Manual Recline shown
1-5

To return the seatback to an upright position, do the
following:
1. Lift the lever fully without applying pressure to the
seatback and the seatback will return to the upright
position.
2. Push and pull on the seatback to make 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 the 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 head
restraint down.
1-7

Passenger Folding Seatback
{CAUTION:
If you fold the seatback forward to carry longer
objects, such as skis, be sure any such cargo
is not near an airbag. In a crash, an inflating
airbag might force that object toward a person.
This could cause severe injury or even death.
Secure objects away from the area in which
an airbag would inflate. For more information,
see Where Are the Airbags? on page 1-55 and
Loading Your Vehicle on page 4-22.
{CAUTION:
Things you put on this seatback can strike and
injure people in a sudden stop or turn, or in a
crash. Remove or secure all items before
driving.
If the vehicle has this feature, the front passenger seat
can be folded flat for more cargo space.
To fold the front passenger seatback flat, pull up on the
lever located on back of the seat. Push the seatback
forward until it locks in place.
To return the seatback to the upright position, pull up on
the lever on the back of the seat. Push the seatback
up until it locks in place.
1-8

{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.
Push and pull on the seatback to make sure it is locked.
Rear Seats
Split Folding Rear Seat
Both sides of the rear seatback can be folded down.
This gives direct access to the trunk. Make sure the front
seats are not reclined. If they are, the rear seatback(s)
may not fold down all the way.
Notice: Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
To lower the rear seatback,
pull the tab located on the
outboard side of the
seatback and fold the
seatback forward.
{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.
To raise the rear seatback, lift the seatback up until it
latches. Push and pull on the seatback to be sure it is
locked in position.
The seatbacks should be kept in the upright, locked
position when they are not being used to extend the
cargo area.

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 3-41.
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!
1-10

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.
1-11

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...
1-12

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.
1-13

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.

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 1-29 or Infants and
Young Children on page 1-32. 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.
1-15

Q: What is wrong with this?
A: The shoulder belt is too loose. It will not give 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.
