Rear Seats (All Split
Bench and Hybrid Full
Bench)
Folding Rear Seat
Either side of the rear seat can be
folded for added cargo space.
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.
Make sure that nothing is on
the seat.
To fold the seat, slowly pull the seat
cushion up. To return the seat to the normal
seating position, slowly pull the
seat cushion down.
Make sure the safety belts are
not twisted or caught in the seat
cushion.
{WARNING
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.
Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
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.

{WARNING
People riding on the tailgate
(if equipped) can easily lose their
balance and fall even when the
vehicle is operated at low speeds.
Falling from a moving vehicle may
result in serious injuries or death.
{WARNING
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
the vehicle is in a seat and using
a safety belt properly.This vehicle has indicators as a
reminder to buckle the safety belts.
See
Safety Belt Reminders on
page 5‑19 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.

{WARNING
You can be seriously hurt if the
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.Q: What is wrong with this?
A:
The lap belt is too loose.
It will not give nearly as
much protection this way.
{WARNING
You can be seriously hurt if the
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.

Q: What is wrong with this?
A:The belt is buckled in the wrong
buckle.
{WARNING
You can be seriously injured
if the 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 the belt
into the buckle nearest you. Q: What is wrong with this?
A:
The belt is over an armrest.

Seats and Restraints 3-19
{WARNING
You can be seriously injured if the
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.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.
{WARNING
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.

Q: What is wrong with this?
A:The belt is behind the body.
{WARNING
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. Q: What is wrong with this?
A:
The belt is twisted across
the body.
{WARNING
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 to fix it.

3. Be sure that the belt isnot twisted and it lies flat.
The elastic cord must be under
the belt and the guide on top.
{WARNING
A safety belt that is not properly
worn may not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. 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.
4. Buckle, position, and releasethe safety belt as described
previously in this section. Make
sure the shoulder portion of the
belt is on the shoulder and not
falling off of it. The belt should
be close to, but not contacting,
the neck.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide onto the storage clip.

Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts After a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in
a crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑20.

Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front
passenger.
The vehicle may have the following
airbags:
.A seat‐mounted side impact
airbag for the driver.
.A seat‐mounted side impact
airbag for the right front
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the right
front passenger and the person
seated directly behind the right
front passenger. All of the airbags in the vehicle will
have the word AIRBAG embossed
in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger.
With seat‐mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job. Here are the most important things
to know about the airbag system:
{WARNING
You can be severely injured or
killed in a crash if you are not
wearing your safety belt
—even
if you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed
to deploy in every crash. In some
crashes safety belts are your only
restraint. See When Should an
Airbag Inflate? on page 3‑32.
Wearing your safety belt during a
crash helps reduce your chance
of hitting things inside the vehicle
or being ejected from it. Airbags
are “supplemental restraints” to
the safety belts. Everyone in your
vehicle should wear a safety belt
properly —whether or not there is
an airbag for that person.

{WARNING
Airbags inflate with great force,
faster than the blink of an eye.
Anyone who is up against, or
very close to, any airbag when it
inflates can be seriously injured
or killed. Do not sit unnecessarily
close to any airbag, as you would
be if you were sitting on the edge
of the seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear a safety belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on
or sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children,
but not for young children and
infants. Neither the vehicle
safety belt system nor its airbag
system is designed for them.
Young children and infants
need the protection that a child
restraint system can provide.
Always secure children properly
in the vehicle. To read how, see
Older Children on page 3‑49or
Infants and Young Children on
page 3‑51.
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light on page 5‑20
for more information.
