Section 1 Seats and Restraint System
1-1

{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.
1-11

Center Seat
Your vehicle may have a front center seat. This seat can
be converted to a storage area by lowering the seatback.
SeeCenter Flex Storage Unit on page 2-57.
Rear Seats
Rear Seat Pass-Through Door
Your vehicle has a pass-through door that provides
access to the trunk from the rear seats. See “Rear Seat
Pass-Through Door” underTrunk on page 2-13.
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.
1-12

{CAUTION:
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.
{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.
This vehicle has indicators as a reminder to buckle the
safety belts. SeeSafety Belt Reminders on page 3-35
for additional information.

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:Youcouldbe — whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so youcanunbuckle
and get out, ismuchgreater 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
workwithsafety 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.
1-17

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, seeOlder Children on page 1-35
orInfants and Young Children on page 1-38. 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.
1-18

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 t snugly against your body.
1-20

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.
1-21

Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
except for the center front passenger position
(if equipped), which has a lap belt. SeeLap Belt
on page 1-33for more information.
The following instructions explain how to wear a
lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-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.
If the shoulder portion of a passenger belt is pulled
out all the way, the child restraint locking feature
may be engaged. If this happens, just let the belt go
back all the way and start again.
Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-67for more information.3. Push the latch plate into the buckle until it clicks.
If the latch plate will not go fully into the buckle,
check if the correct buckle is being used.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-34.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
