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.
This could allow cargo to slide

seatback and return it slowly. Ensure
that the seatback is completely locked
into its upright position by pushing on
the top of the seatback. In an accident
or sudden stop, the unlocked seatback
could allow cargo to move forward with
great force and enter the passenger
compartment, which could result in
serious injury or death.
WARNING
Do not place objects in the rear seats,
since they cannot be properly secured
and may hit vehicle occupants in a
collision causing serious injury or death.
WARNING
Make sure the engine is off, the gear
shifted to P (Park), and the parking
brake is securely applied whenever
loading or unloading cargo. Failure
to take these steps may allow the
vehicle to move if the shift button
is inadvertently pressed to another
position.
CAUTION
• Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
• When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.
WARNING
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.

Head restraint
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly they
are designed to help protect passengers
from whiplash and other neck and spinal
injuries during an accident, especially in
a rear impact collision.
WARNING
To reduce the risk of serious injury or
death in an accident, take the following
precautions when adjusting your head
restraints:
• Always properly adjust the head
restraints for all passengers BEFORE
starting the vehicle.
• NEVER let anyone ride in a seat
with the head restraint removed or
reversed.

• Adjust the head restraint as close to
the passenger’s head as possible. Do
not use a seat cushion that holds the
body away from the seatback.

into position after adjusting it.
