WARNING
When returning the rear seatback from
a folded to an upright position, hold the
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, an 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 vehicle is off, the shift
button is in 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 moved to another position. Armrest (if equipped)
ODN8039018
The armrest is located in the center of
the rear seat. Pull the armrest down from
the seatback to use it.
Head Restraints
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 restraints removed or
reversed.

stop the vehicle.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
