CAUTION
Avoid reclining the seatback any
more than needed. The seat belts pro-
vide maximum protection in a frontal
or rear collision when the driver and
the front passenger are sitting up
straight and well back in the seats. If
you are reclined, the lap belt may
slide past your hips and apply re-
straint forces directly to the abdomen
or your neck may contact the shoul-
der belt. In the event of a frontal
collision, the more the seat is re-
clined, the greater the risk of death
or personal injury.

When returning seats to their origi-
nal position, observe the following
precautions in order to prevent per-
sonal injury in a collision or sud-
den stop:
Be careful not to get your hands or
feet pinched in the seat.
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.
Folding the seats up will enlarge the lug-
gage compartment. See “—Stowage pre-
cautions” on page 389 in Section 2 for
precautions when loading luggage.
