But don’t have a seatback reclined if your vehicle
is moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can not do their
job when you are reclined like this.
The shoulder belt can not do its job because it
will not 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 not 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.

{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That
could cause injury to the person sitting there.
Always press rearward on the seatback to
be sure it is locked.
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 tip of a key into
the release hole of the
safety belt attachment
while pulling up on
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.
5. Lift up on the left and the right seat release levers
at the same time. The latches are near the oor on
the rear legs of the seat.6. Lift up on the rear of the seat to remove the
seat assembly from the rear latch pins. Then,
pull the whole seat back to remove the seat from
the front retainers and then lift the seat out of
the vehicle.

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.
{CAUTION:
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.
Bench Seat
Each bench seat can carry up to three passengers.
They can also be removed to increase storage space.
Only the rear bench seat can be adjusted forward
or rearward using the lever at the front of the seat.

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.
{CAUTION:
Do not let anyone ride where he or she can
not wear a safety belt properly. If you are in a
crash and you are 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.
{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.
Your vehicle has a light
that comes on as a
reminder to buckle up.
SeeSafety Belt Reminder
Light on page 3-24.
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.
