—Adjusting third seats
1. SEAT POSITION ADJUSTING LEVER
Hold the center of the lever and pull it
up. Then slide the seat to the desired
position with slight body pressure and
release the lever.
When a person sits on the third seat
center position, adjust both seats to the
same position.
Do not place anything under the seats. It
might interfere with the seat−lock mecha-
nism.
2. SEATBACK ANGLE ADJUSTING
LEVER
Lean forward and pull the lever up.
Then lean back to the desired angle
and release the lever.
When a person sits on the third seat
center position, adjust both seatbacks
to the same angle.CAUTION
Adjust both seats to the same posi-
tion and seatbacks to the same
angle when a person sits on the
third seat center position. Other-
wise, the person can not wear seat
belt properly and this may cause
serious injuries in a collision.
To reduce the risk of sliding under
the lap belt during 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.
Therefore, in the event of a frontal
collision, the risk of personal injury
may increase with increasing recline
of the seatback.
