Head Restraints
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can't do their job
when you're reclined like
this.
The shoulder belt can't do its job because it
won't be against your body. Instead, it will be
in front of you.
In a crash you could go into it,
receiving neck or other injuries.
The lap belt can't
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. Adjust
your head restraint
so that the top of the restraint
is closest to the top
of your head. This position
reduces the chance
of a neck injury in a crash.

Rear Seats
Rear Seat Operation
Removing the Rear Seats
To remove the rear seats, do the following:
1. If you are removing the
center seat, remove
the right lap-shoulder
belt.
To do this, press
the release hole of the
safety belt attachment
while pulling up on
SEAT REMOVAL the tip of a key into
I INSERT KEY the safety belt. 2.
If you have a safety
belt guide on your
seat, pull the safety
belt all the way
out through the guide.
3. To store the safety belt while the second row bench
seat is removed, pull the belt out and put both
buckles in the passenger’s side rear storage bin.
Route the belt out of the forward edge of the
storage bin. Close the cover to retain the belt.
4. Pull up on the seatback latch on the right rear of
the seat. Push the seatback down until it locks
into place.

3. To raise the seatback, do the following:
3.1. Unlock the seatback latch by pulling up on
the latch release lever at the right rear
of the
seat, while pushing down on the upper
edge of the seatback.
3.2. Move the seatback into the upright position.
Make sure the seatback is locked when it is
back in the upright position.
If you are replacing the center seat, connect the right
lap-shoulder belt to the attachment on the seat cushion.
If you have a safety belt guide
on your seat, pull the
belt through the guide before reattaching the
lap-shoulder belt to the side
of the seat. The release
hole should be facing outward.
If you installed the safety belt with the release hole facing
inward (toward the seat), slide the plastic cover up
so you
can see the buckle. Disconnect the seat belt. Slide the
cover back down and reinstall the belt correctly.
A safety
--It that __ impropc routed, not
properly attached, or twisted won’t 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
r-+ do with safety belts.
Don’t let anyone ride where he or she can’t
wear a safety
belt properly. If you are in a
crash and you’re not wearing a safety belt,
your injuries can be much worse. You can
hit
things inside the vehicle or be ejected from it.
You 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 passengers’ belts are
fastened properly too.
it is extremely dangerous to ride in a CN~G
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 a light
that comes
on as a
reminder to buckle up.
See
Safety Belt Reminder
Light on page 3-26.

In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why:
They work.
You never know if you’ll be in a crash. If you do have
a crash, you don’t know
if it will be a bad one.
A few crashes are mild, and some crashes can be
so
serious that even buckled up, a person wouldn’t 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
30 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’s just a seat
on wheels.
