Safety features of your vehicle83HeadrestThe 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 to protect the head and neck
in the event of a collision.Adjusting the height up and down
To raise the headrest, pull it up to the
desired position (1). To lower the head-
rest, push and hold the release button (2)
on the headrest support and lower the
headrest to the desired position (3).
OYF039010
WARNING
 For maximum effectiveness in
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.
