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 a seatback reclined if your vehicle is moving.

Rear Seats
Rear Seat Operation
Your vehicle has ip and fold second row seats which
provide additional cargo space.
To ip and fold the seat(s), do the following:
1. Pull up on the loop located where the seat cushion
meets the seatback and ip the seat cushion
forward.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.
2. Lift the lever, located
on the outboard side of
the seatback, and
fold the seatback
forward.
The head restraint will automatically fold out of the
way as the seatback is folded down.

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:
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 3-30
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.
