{WARNING:
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.
Your vehicle has a memory function which allows seat
settings to be saved and recalled. See Memory
Features on page 2‑6.

Rear Seats
Rear Seat Operation (Split Bench)
Folding Rear Seat
On a vehicle with a second row 60/40 split seat either
side of the rear seat may 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.
{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
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not 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 your vehicle is in a seat and using a
safety belt properly.
Your vehicle has indicators as a reminder to buckle your
safety belts. See Safety Belt Reminders on page 4‑30.

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 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.
2-12

Put someone on it.Get it up to speed. Then stop the vehicle. The rider
does not stop.
2-13

The person keeps going until stopped by something. In
a real vehicle, it could be the windshield...or the instrument panel...
