case of an accident, the headrest
should be adjusted so the middle
of the headrest is at the same
height of the center of gravity of
an occupant's head. Generally,
the center of gravity of most peo-
ple's head is similar with the
height of the top of their eyes.
Also, adjust the headrest as close
to your head as possible. For this
reason, the use of a cushion that
holds the body away from the
seatback is not recommended.
• Do not operate the vehicle with the headrests removed as severe
injury to the occupants may
occur in the event of an accident.
Headrests may provide protec-
tion against neck injuries when
properly adjusted.
• Do not adjust the headrest posi- tion of the driver's seat while the
vehicle is in motion.

WARNING
Make sure the headrest locks in
position after adjusting it to proper-
ly protect the occupants.

3Folding the rear seatThe rear seatbacks can be folded to facil-
itate carrying long items or to increase
the luggage capacity of the vehicle.
To fold down the rear seatback:
1. Insert the rear seat belt buckle in thepocket (if equipped) between the rear
seatback and cushion. 2. Make sure the rear seat belt webbing
is in the guide to prevent the seat belt
from being damaged.
3. Set the front seatback to the upright position and if necessary, slide the
front seat forward.
4. Lower the rear headrests to the lowest position.
WARNING
The purpose of the fold-down rear
seatbacks is to allow you to carry
longer objects that could not be
accommodated in the cargo area.
Never allow passengers sit on top
of the folded down seatback while
the vehicle is moving. This is not a
proper seating position and no seat
belts are available for use.
This could result in serious injury
or death in case of an accident or
sudden stop. Objects carried on the
folded down seatback should not
extend higher than the top of the
front seatbacks. Doing this could
allow cargo to slide forward and
cause injury or damage during sud-
den stops.
