Folding the rear seat
The rear seatbacks (or cushions) may 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 as 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 seats. This
could allow cargo to slide forward
and cause injury or damage during
sudden stops.

Safety system
WARNING
When you return the rear seatback to
its upright position after being folded
down:
Be careful not to damage the seat belt
webbing or buckle. Do not allow the
seat belt webbing or buckle to get
caught or pinched in the rear seat.
Ensure that the seatback is completely
locked into its upright position by
pushing on the top of the seatback.
Otherwise, in an accident or sudden
stop, the seat could fold down and
allow cargo to enter the passenger
compartment, which could result in
serious injury or death.
NOTICE
• When returning the rear seatbacks
to the upright position, remember to
return the rear shoulder belts to their
proper position.
• Routing the seat belt webbing
through the rear seat belt guides will
help keep the seat belts from being
trapped behind or under the seats.
WARNING
Cargo
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.
WARNING
Cargo loading
Make sure the engine is off, the
Intelligent variable transmission is in P
(Park) or the Manual transmission is in R
(Reverse) or 1st, 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 lever is inadvertently moved to
another position.

SEAT BELTS
WARNING
• For maximum restraint system
protection, the seat belts must
always be used whenever the car is
moving.
• Seat belts are most effective when
seatbacks are in the upright position.
• Children age 12 and under must
always be properly restrained in the
rear seat. Never allow children to
ride in the front passenger seat. If a
child over 12 must be seated in the
front seat, he/she must be properly
belted and the seat should be moved
as far back as possible.
• Never wear the shoulder belt under
your arm or behind your back. An
improperly positioned shoulder
belt can cause serious injuries in
a crash. The shoulder belt should
be positioned midway over your
shoulder across your collarbone.
• Never wear a seat belt over fragile
objects. If there is a sudden stop or
impact, the seat belt can damage it.
• Avoid wearing twisted seat belts. A
twisted belt can’t do its job as well. In
a collision, it could even cut into you.
Be sure the belt webbing is straight
and not twisted.
• Be careful not to damage the belt
webbing or hardware. If the belt
webbing or hardware is damaged,
replace it.
WARNING
Seat belts are designed to bear upon
the bony structure of the body, and
should be worn low across the front
of the pelvis or the pelvis, chest and
shoulders, as applicable; wearing
the lap section of the belt across the
abdominal area must be avoided.
Seat belts should be adjusted as firmly
as possible, consistent with comfort, to
provide the protection for which they
have been designed.
A slack belt will greatly reduce the
protection afforded to the wearer.
Care should be taken to avoid
contamination of the webbing with
polishes, oils and chemicals, and
particularly battery acid. Cleaning
may safely be carried out using mild
soap and water. The belt should be
replaced if webbing becomes frayed,
contaminated or damaged.
It is essential to replace the entire
assembly after it has been worn in a
severe impact even if damage to the
assembly is not obvious. Belts should
not be worn with straps twisted. Each
belt assembly must only be used by
one occupant; it is dangerous to put a
belt around a child being carried on the
occupant’s lap.

4-16
Safety system
WARNING
• 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.
• When you fasten the seat belt, be
careful not to latch the seat belt
in buckles of other seat. It’s very
dangerous and you may not be
protected by the seat belt properly.
• Do not unfasten the seat belt and
do not fasten and unfasten the seat
belt repeatedly while driving. This
could result in loss of control, and
an accident causing death, serious
injury, or property damage.
• When fastening the seat belt, make
sure that the seat belt does not pass
over objects that are hard or can
break easily.
• Make sure there is nothing in the
buckle. The seat belt may not be
fastened securely.

the proper length only after the lap belt
portion is adjusted manually so that it
fits snugly around your hips. If you lean
forward in a slow, easy motion, the belt
will extend and let you move around.
If there is a sudden stop or impact,
however, the belt will lock into position.
It will also lock if you try to lean forward
too quickly.

If you are not able to pull out the safety
belt from the retractor, firmly pull the
belt out and release it. After release, you
will be able to pull the belt out smoothly.
