Seats & Safety System
3-2
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate child restraint. Larger
children should use a booster seat with
the lap/shoulder belt until they can use
the seat belt properly without a booster
seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and shorter adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel,
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers, and using cellular phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving. To
reduce your risk of distraction or getting
into an accident: •
ALWAYS set up your mobile devices
(i.e., MP3 players, phones, navigation
units, etc.) when your vehicle is
parked or safely stopped.
• ONLY use your mobile device when
allowed by laws and when conditions
permit safe use. NEVER text or email
while driving. Most countries have
laws prohibiting drivers from texting.
Some countries and cities also
prohibit drivers from using handheld phones.
• NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle in Safe Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.

Safety Precautions
Adjusting the seats so that you are sitting
in a safe, comfortable position plays an
important role in driver and passenger
safety together with the seat belts and
air bags in an accident.
WARNING
Do not use a cushion that reduces
friction between the seat and the
passenger. The passenger’s hips may
slide under the lap portion of the seat
belt during an accident or a sudden
stop. Serious or fatal internal injuries
could result because the seat belt
cannot operate properly. Air bags
You can take steps to reduce the risk
of being injured by an inflating air bag.
Sitting too close to an air bag greatly
increases the risk of injury in the event
the air bag inflates.
Move your seat as far back as
possible from front air bags, while still
maintaining control of the vehicle.
WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions: • Adjust the driver’s seat as far to the
rear as possible while maintaining
the ability to maintain full control of
the vehicle.
• Adjust the front passenger seat as far
to the rear as possible.
• Hold the steering wheel by the rim
with hands at the 9 o’clock and 3
o’clock positions to minimize the risk
of injuries to your hands and arms. •
NEVER place anything or anyone
between the steering wheel and the air bag.
• Do not allow the front passenger to
place feet or legs on the dashboard
to minimize the risk of leg injuries.
Seat belts
Always fasten your seat belt before
starting any trip.
At all times, passengers should sit
upright and be properly restrained.
Infants and small children must be
restrained in appropriate child restraint
systems. Adults and children who
have outgrown a booster seat must be
restrained using the seat belts.
WARNING
Take the following precautions when
adjusting your seat belt: • NEVER use one seat belt for more
than one occupant.
• Always position the seatback upright
with the lap portion of the seat belt
snug and low across the hips.
• NEVER allow children or small infants
to ride on a passenger’s lap.
• Do not route the seat belt across your
neck, across sharp edges, or reroute
the shoulder strap away from your
body.
• Do not allow the seat belt to become
caught or jammed.

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.
ODN8039002
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.
ODN8039004
Seat cushion height
To change the height of the seat cushion: •
Push down on the lever several times,
to lower the seat cushion.
• Pull up on the lever several times, to
raise the seat cushion.

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.
ODN8039062L
2. Lower the rear head restraints to the lowest position by pushing and
holding the release button and
pushing down on the head restraint.

4. Fold the seatback toward the front of
the vehicle.
5. To use the rear seat, lift and pull the seatback rearward. Pull the seatback
firmly until it clicks into place. Make
sure the seatback is locked in place.

Seat BeltS
This section describes how to use the
seat belts properly. It also describes
some of the things to avoid when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
but they are not a substitute. Most
countries require all occupants of a
vehicle to wear seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts: • ALWAYS properly restrain children
under age 13 in the rear seats.
• NEVER allow children to ride in the
front passenger seat. If a child age 13
or older must be seated in the front
seat, move the seat as far back as
possible and properly restrain them
in the seat.
• NEVER allow an infant or child to be
carried on an occupant’s lap.
• NEVER ride with the seatback
reclined when the vehicle is moving.
• Do not allow children to share a seat
or seat belt.
• Do not wear the shoulder belt under
your arm or behind your back.
• Always wear both the shoulder
portion and lap portion of the lap/shoulder belt.
• Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.
• Do not use a seat belt if the webbing
or hardware is damaged. •
Do not latch the seat belt into the
buckles of other seats.
• NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an
accident.
• Make sure there is nothing in the
buckle interfering with the seat belt
latch mechanism. This may prevent
the seat belt from fastening securely.
• No modifications or additions
should be made by the user which
will either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace: • Frayed, contaminated, or damaged
webbing
• Damaged hardware
• The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent
