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.

Power adjustment (if equipped)
The front seat can be adjusted by
using the control switches 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.
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.
ODN8039005
Forward and rearward adjustment
To move the seat forward or rearward:
1. Push the control switch forward or rearward.
2. Release the switch once the seat reaches the desired position.

Seat Warmers and Air Ventilation
Seats
Seat warmers (if equipped)
Seat warmers are provided to warm the
seats during cold weather.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers: • Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:
Never use a solvent such as paint
thinner, benzene, alcohol or gasoline to
clean the seats.
Do not place heavy or sharp objects on
seats equipped with seat warmers.
Do not change the seat cover. It
may damage the seat warmer or air
ventilation system.

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

NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
Height adjustment
You can adjust the height of the shoulder
belt anchor to one of the three different
positions for maximum comfort and
safety. The shoulder portion should be
adjusted so it lies across your chest and
midway over your shoulder nearest the
door, not over your neck. To adjust the
height of the seat belt anchor, lower
or raise the height adjuster into an
appropriate position.
„„Front seat
ODN8039072L
To raise the height adjuster, pull it up
(1). To lower it, push it down (3) while
pressing the height adjuster button (2).
Release the button to lock the anchor
into position. Try sliding the height
adjuster to make sure that it has locked
into position.
OHI038142
To release your seat belt:
Press the release button (1) in the locking buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen, check
the belt to be sure it is not twisted, then try again.
Rear Seat Belt – Passenger’s 3-point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.

03
3-23
To fasten your seat belt:
Pull the seat belt out of the retractor
and insert the metal tab into the buckle.
There will be an audible “click” when
the tab locks into the buckle. When
not securing a child restraint, the seat
belt operates in the same way as the
driver’s seat belt (Emergency Locking
Retractor Type). It automatically adjusts
to the proper length only after the lap
belt portion of the seat belt is adjusted
manually so that it fits snugly across your hips.
When the seat belt is fully extended from
the retractor to allow the installation of
a child restraint system, the seat belt
operation changes to allow the belt to
retract, but not to extend (Automatic
Locking Retractor Type). Refer to the
“Using a Child Restraint System” section
in this chapter.
NOTICE
Although the seat belt retractor
provides the same level of protection
for seated passengers in either
emergency or automatic locking
modes, the emergency locking mode
allows seated passengers to move
freely in their seat while keeping
some tension on the belt. During a
collision or sudden stop, the retractor
automatically locks the belt to help
restrain your body.
To deactivate the automatic locking
mode, unbuckle the seat belt and allow
the belt to fully retract.Rear center seat belt
ODN8039074L
When using the rear center seat belt, the
buckle with the “CENTER” mark must be used.
WARNING
Make sure that the seatback is locked in
place when using the rear center seat belt.
If not, the seatback may move when
there is a sudden stop or collision,
which could result in serious injury.
