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.

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.

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.
