Head Restraints
The vehicle’s front seats have adjustable head restraints
in the outboard seating positions.
{ CAUTION:
With head restraints that are not installed and
adjusted properly, there is a greater chance that
occupants will suffer a neck/spinal injury in a
crash. Do not drive until the head restraints for all
occupants are installed and adjusted properly.
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.
1-2

1-11
{ 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.
1-12
Center Seat
The 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 2-56.
Rear Seats

access to the trunk from the rear seats. See “Rear Seat
Pass-Through Door” under Trunk on page 2-13.
1-13
Safety Belts
Safety Belts: They Are for Everyone
This section of the manual describes how to use
safety belts properly. It also describes some things not
to do with safety belts.
{ CAUTION:
{ 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.
Do not let anyone ride where a safety belt cannot
be worn properly. In a crash, if you or your
passenger(s) are not wearing safety belts, the
injuries can be much worse. You can hit things
inside the vehicle harder or be ejected from the
vehicle. You and your passenger(s) 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 passenger(s)
are restrained properly too.
1-14
This vehicle has indicators as a reminder to buckle the
safety belts. See Safety Belt Reminders on page 3-37
for additional information.
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 safety 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.
1-15
Put someone on it.Get it up to speed. Then stop the vehicle. The rider
1-16
does not stop.
The person keeps going until stopped by something.
In a real vehicle, it could be the windshield...
or the instrument panel...
1-17
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.
1-18
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 infants. If a child will be
riding in the vehicle, see Older Children on page 1-35 or
Infants and Young Children on page 1-39. 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.
1-19
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.
1-20
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.
1-21
Q: What is wrong with this?
A: The lap belt is too loose. It will not give nearly 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.
1-22
Q: What is wrong with this?
A: The belt is buckled in the wrong buckle.
{ 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.
1-23
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.
1-24
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.
1-25
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.
