CAUTION
When reinstalling the seat, observe
the following to prevent personal inju-
ry:
Do not reinstall the seat while the
vehicle is moving.
Be careful not to get your hands or
feet pinched in the seat.
Be careful not to hit the removed
seat against a person or drop it on
yourself.
After folding or installing the seat,
push it forward and backward to
make sure it is locked in position.
When reinstalling seats to their origi-
nal position, observe the following
precautions in order to prevent per-
sonal injury in a collision or s udden
stop:
Make sure the seat is securely
locked by pushing forward and rear-
ward on the top of the seatback or
by trying to pull up the edge of the
bottom cushion. Failure to do so
will prevent the seat belt from oper-
ating properly.
Make sure the seat belts are not
twisted or caught under the seat
and are arranged in their proper
position and are ready to use.
Install each seat in the same posi-
tion from which it was removed.
Failure to do so will prevent the
occupants from using seat belts
properly.
Do not reinstall the seat with its
back facing forward.
Make sure the seat is securely
locked in the proper position.
NOTICE
Do not carry the removed seat by
holding the seat position adjusting le-
ver.

SEATBACK ANGLE ADJUSTING STRAP
Lean forward and pull the strap for-
ward. Then lean back to the desired
angle and release the strap.
CAUTION
Align both seatbacks at the same
angle when a person sits in the
third seat center position. Other-
wise, the person cannot wear the
seat belt properly and this may
cause serious injuries in a collision.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
passengers are sitting up straight
and well back in the seats. If you
are reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen or
your neck may contact the shoulder
belt. In the event of a frontal colli-
sion, the more the seat is reclined,
the greater the risk of death or per-
sonal injury.BEFORE STOWING THIRD SEATS1. Stow the third seat belt buckles as shown in the illustration.
This prevents the belt buckles from falling
out when you stow the third seat.
NOTICE
The seat belt buckles must be stowed
before you stow the third seat.
2. To stow the center seat belt, pull it slightly out of its cover. It will auto-
matically roll back partway. Roll the
seat belt backwards as shown above
and insert it into the slot of its cov-
er. Make sure the tabs are securely
locked in the cover.
NOTICE
The seat belt must be stowed before
you fold the seatback.
