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.

BRAKE SYSTEM
Power Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied.
Do not pump the brake pedal when the
power assist has been interrupted.
Only pump the brakes on slippery
surfaces if the power assist has been
interrupted to maintain steering control.
Do not pump the brakes on slippery
surfaces if the brakes are operating
normally.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending down a long or
steep hill, move the gear shift button
to Manual Shift Mode and manually
downshift to a lower gear in order
to control your speed without using
the brake pedal excessively. Applying
the brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle's
ability to safely slow down; the
vehicle may also pull to one side
when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test your
brakes in this fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
Disc Brakes Wear Indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.
