SITTING IN THE CORRECT
POSITION
WARNING: Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING: Do not recline the seat
backrest too far as this can cause the
occupant to slide under the seatbelt,
resulting in personal injury in the event
of a crash. WARNING:
Do not place objects
higher than the top of the seat backrest.
Failure to follow this instruction could
result in personal injury or death in the
event of a sudden stop or crash. When you use them properly, the seat,
head restraint, seatbelt and airbags will
provide optimum protection in the event
of a crash. We recommend that you follow these
guidelines:
•
Sit in an upright position with the base
of your spine as far back as possible.
• Do not recline the seat backrest so that
your torso is more than 30 degrees
from the upright position.
• Adjust the head restraint so that the
top of it is level with the top of your
head and as far forward as possible.
Make sure that you remain
comfortable.
• Keep sufficient distance between
yourself and the steering wheel. We
recommend a minimum of
10 in
(25 cm) between your breastbone and
the airbag cover.
• Hold the steering wheel with your arms
slightly bent.
• Bend your legs slightly so that you can
press the pedals fully.
• Position the shoulder strap of the
seatbelt over the center of your
shoulder and position the lap strap
tightly across your hips.
Make sure that your driving position is
comfortable and that you can maintain full
control of your vehicle.
HEAD RESTRAINTS WARNING:
Fully adjust the head
restraint before you sit in or operate your
vehicle. This will help minimize the risk
of neck injury in the event of a crash. Do
not adjust the head restraint when your
vehicle is moving.

WARNING: The head restraint is a
safety device. Whenever possible it
should be installed and properly
adjusted when the seat is occupied.
Failure to adjust the head restraint
properly could reduce its effectiveness
during certain impacts.
Note: Adjust the seat backrest to an upright
driving position before adjusting the head
restraint. Adjust the head restraint so that
the top of it is level with the top of your head
and as far forward as possible. Make sure
that you remain comfortable. If you are
extremely tall, adjust the head restraint to
its highest position.
