head, hands or other body parts are
trapped by a closing window. Always
check for obstructions before raising
any window.
o NEVER leave the ignition key in the

o NEVER leave any child unattended in
the vehicle. Even very young children
may inadvertently cause the vehicle
to move, entangle themselves in the
windows, or otherwise injure
themselves or others.
o Do not attempt to operate the main
switch on the driver's door and a
switch on another door in opposing

between the window glass and the
upper window channel, the automatic
reverse window may not detect the
resistance and will not stop and

WARNING:
Riding with a reclined seatback in-
creases your chance of serious or fatal
injuries in the event of a collision or
sudden stop. The protection of your
restraint system (seat belts and airbags)
is greatly reduced by reclining your seat.
Seat belts must be snug against your
hips and chest to work properly. The
more the seatback is reclined, the greater
the chance that an occupant's hips will
slide under the lap belt or the occupant's
neck will strike the shoulder belt. Drivers
and passengers should always sit well
back in their seats, properly belted, and
with the seatbacks upright.
B080E01CM-AATHeadrestThe driver's and front passenger's seats
are equipped with a headrest for the
occupant's safety and comfort.
The headrest not only provides comfort for
the driver and front passenger, but also
helps protect the head and neck in the
event of a collision.
OMG038400
To lock the seatback into position, release
the recliner control lever.
B080D02JM-AATAdjustable HeadrestsHeadrests are designed to help reduce
the risk of neck injuries.
To raise the headrest, pull it up. To lower
the headrest, push it down while pressing
the lock knob. To remove the headrest,
raise it as far as it can go then press the lock
knob while pulling upward. This should
only be done when the seat is not occupied.

o Do not operate the vehicle with the
headrests removed as injury to the
occupants may occur in the event of
an accident. Headrests may provide
protection against neck injuries when
properly adjusted.
o Do not adjust the headrest position of
the driver's seat while the vehicle is in
motion.
B082D01CM-AATRemovalTo remove the headrest, raise it as far as
it can go then press the release button (1)
while pulling the headrest up (2).
To reinstall the headrest, put the headrest
poles (3) into the holes while pressing the
release button (1). Then adjust it to the
appropriate height.
ONF039041
WARNING:
Make sure the headrest locks in position
after adjusting it to properly protect the
occupants.
!
!
WARNING:
o For maximum effectiveness in case
of an accident, the headrest should be
adjusted so the middle of the head-
rest is at the same height of the center
of gravity of an occupant's head. Gen-
erally, the center of gravity of most
people'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.
