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.

locked by pushing forward and rear-
ward on the top of the seatback or

ating properly.

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 collision, the more the seat is
reclined, the greater the risk of death
or personal injury.
For access to the third seat, perform
the following procedure.
Fold down the seatback while pulling the
seatback angle adjusting lever or strap
and swing up the seat.
After passengers are in, return the seat
