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
ODN8039018ODN8039018
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.

ODN8039052LODN8039052L
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
ODN8A039053ODN8A039053
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
ODN8039059ODN8039059
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
ODN8039054ODN8039054
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.

the brake, move the shift button to the
P (Park) position, engage the parking
brake, and place the ignition switch
in the LOCK/OFF position, close all

WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the ignition switch or related
parts. Unexpected and sudden
vehicle movement can occur.
• NEVER reach through the steering
wheel for the ignition switch, or any
other control, while the vehicle is in
motion. The presence of your hand

Whenever the front door is opened, the
ignition switch will illuminate, provided
the ignition switch is not in the ON
position. The light will go off immediately
when the ignition switch is turned on or
go off after about 30 seconds when the
door is closed. (if equipped)
WARNING
NEVER turn the ignition switch to the
LOCK or ACC position while the vehicle
is in motion except in an emergency.
This will result in the engine turning
off and loss of power assist for the
steering and brake systems. This may
lead to loss of directional control and
braking function, which could cause an
accident.
Before leaving the driver's seat, always
make sure the shift button is in P (Park)
position, apply the parking brake,
and turn ignition switch to the LOCK
position.
Unexpected vehicle movement may
occur if these precautions are not
followed.
