Front Seats
WARNING
Take the following precautions when
adjusting your seat:
• NEVER attempt to adjust the seat
while the vehicle is moving. The seat
could respond with unexpected
movement and may cause loss
of vehicle control resulting in an
accident.
• Do not place anything under the
front seats. Loose objects in the
driver’s foot area could interfere
with the operation of the foot pedals,
causing an accident.
• Do not allow anything to interfere
with the normal position and proper
locking of the seatback.
• Do not place a cigarette lighter on
the floor or seat. When you operate
the seat, gas may exit out of the
lighter causing a fire.
• Use extreme caution when picking
up small objects trapped under the
seats or between the seat and the
center console. Your hands might be
cut or injured by the sharp edges of
the seat mechanism.
• If there are occupants in the rear
seats, be careful while adjusting the
front seat position.
• Make sure that the seat is locked in
place after the adjustment. If not,
the seat might move unexpectedly
resulting in an accident.
CAUTION
To prevent injury:
• Do not adjust your seat while
wearing your seat belt. Moving the
seat cushion forward may cause
strong pressure on your abdomen.
• Do not allow your hands or fingers to
get caught in the seat mechanisms
while the seat is moving.
Manual adjustment (if equipped)
The front seat can be adjusted by using
the levers located on the outside of
the seat cushion. Before driving, adjust
the seat to the proper position so that
you can easily control the steering
wheel, foot pedals and controls on the
instrument panel.

Forward and rearward adjustment
To move the seat forward or rearward:
1. Pull up the seat slide adjustment lever
and hold it.
2. Slide the seat to the position you
desire.
3. Release the lever and make sure the
seat is locked in place. Move forward
and rearward without using the lever.
If the seat moves, it is not locked
properly.

Seatback angle
To recline the seatback:
1. Lean forward slightly and lift up the
seatback lever.
2. Carefully lean back on the seat and
adjust the seatback to the position
you desire.
3. Release the lever and make sure the
seatback is locked in place. (The lever
MUST return to its original position for
the seatback to lock.)
Reclining seatback
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protection of
your restraint system (seat belts and air
bags) is greatly reduced by reclining your
seatback.
WARNING
NEVER ride with a reclined seatback
when the vehicle is moving.
Riding with a reclined seatback
increases your chance of serious or fatal
injuries in the event of a collision or
sudden stop.
Drivers and passengers should ALWAYS
sit well back in their seats, properly
belted, and with the seatbacks upright. Seat belts must be snug against your
hips and chest to work properly. When
the seatback is reclined, the shoulder
belt cannot do its job because it will not
be snug against your chest. Instead,
it will be in front of you. During an
accident, you could be thrown into the
seat belt, causing neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger’s
hips will slide under the lap belt or the
passenger’s neck will strike the shoulder
belt.

controls on the instrument panel.
WARNING
NEVER allow children in the vehicle
unattended. The power seats are
operable when the vehicle is turned off.
NOTICE
To prevent damage to the seats:
• Always stop adjusting the seats when
the seat has moved as far forward or
rearward as possible.
• Do not adjust the seats for longer
than necessary when the vehicle
is turned off. This may result in
unnecessary battery drain.
• Do not operate two or more seats at
the same time.This may result in an
electrical malfunction.

Rear Seats
Folding the rear seat
The rear seatbacks can be folded to
facilitate carrying long items or to
increase the luggage capacity of the
vehicle.
WARNING
• Never allow passengers to sit on top
of the folded down seatback while
the vehicle is moving. This is not a
proper seating position and no seat
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
forward and cause injury or damage
during sudden stops.
To fold down the rear seatback:
1. Set the front seatback to the upright
position and if necessary, slide the
front seat forward.

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
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.

Safety System

middle of the head restraint is at the
same height as the height of the top
of the eyes.
• NEVER adjust the head restraint
position of the driver’s seat when the
vehicle is in motion.
• 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.
• Make sure the head restraint locks
into position after adjusting it.
NOTICE
To prevent damage, NEVER hit or pull
on the head restraints.
CAUTION
When there are no occupants in the
rear seats, adjust the height of the head
restraint to the lowest position. The
rear seat head restraint can reduce the
visibility of the rear area.
