Seat Position
{Warning
Use caution when adjusting the
seat, as failure to do so could
cause injury. You and others
could be seriously injured.
{Warning
Never allow children to adjust
their seats themselves; an adult
should adjust the seat for
occupants who are children. You
and others could be seriously
injured.
{Warning
Adjust the seat only before you
start driving. Adjusting the seat
while the vehicle is in motion
must be avoided not only
because the unlocked seat will
move back and forth unstably,
preventing you from taking the
correct position, but might also
cause you to lose control of the
vehicle, possibly resulting in an
accident. You and others could be
seriously injured.
{Warning
Try to move the seat without
unlatching it after making
adjustments to check that it is
completely locked. A loosely
locked seat may move
unexpectedly and your position
might then become unstable; this
could lead to an accident. Take

Warning (Continued)
the vehicle to your dealer for
service if you find that your seat
adjusters do not latch. In addition,
the seat belt will not operate
properly if the seatback is not
completely locked. You and
others could be seriously injured.
{Warning
Driving with the seat excessively
reclined could be very dangerous
in the event of a collision or
sudden stop. Raise the seatback,
and apply the seat belt correctly
while sitting straight in the seat.
You and others could be seriously
injured.
{Warning
Do not place a cushion or similar
object between your back and the
seatback. Doing so not only
affects the stability of your driving
position but also prevents the
seat belt from working effectively
in the event of a collision. You
and others could be seriously
injured.
{Warning
Do not place any objects under
the seat. If there are any objects
under the seat, the seat could be
locked in an improper position.
You and others could be seriously
injured.
{Warning
Before making adjustments,
check that the seat rails are free
of anything that could obstruct the
locking of the seat. Be careful that
your hand or foot does not
become trapped in the seat or
rails when adjusting the seat. You
and others could be seriously
injured.
{Warning
When adjusting the seat, be
careful that the seat does not hit
passengers or objects. Doing so
could cause injury to passengers,
or damage objects. You and
others could be seriously injured.

{Warning
Make sure not to hit passengers
or luggage when adjusting your
seat. You and others could be
seriously injured.
{Warning
When adjusting the seat, or when
getting up from the seat, do not
put your hand or other objects
under the seat or near moving
parts. Doing so could cause injury
or damage to objects.
Driver’s Seat
The driver's seat must be adjusted
so that when you sit well back in the
seat, you can fully press the pedals
without moving your back from the
seatback, and you can operate the
steering wheel easily and freely.
After making adjustments, check
that the seat is completely locked. Adjusting the seat for a correct
driving posture is a fundamental
part of safe driving.
Forward/backward Adjustment
While raising the unlock lever, move
the seat forward or backward.
Release the lever when the seat is
in the desired position. After making
adjustments, try to move the seat
back and forth to check that it is
fully locked.
Reclining Adjustment
{Warning
To reduce the risk of sliding under
the lap belt during a collision, an
occupied reclining seat should not
be reclined any more than
needed for comfort. The seatback
and seat belts provide best
restraint only when the rider is
sitting well back and straight up in
the seat. (The lap belt is designed
to spread the force of a collision
over the hipbone. If you are
reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen.
Therefore, in the event of a
collision, the risk of personal
injury will increase with increasing
recline of the seatback). You and
others could be seriously injured.

Seats and Restraints 29
{Warning
Do not adjust the reclining
seatback on the driver's seat
while the vehicle is moving. The
seatback could jerk and cause a
loss of control. You and others
could be seriously injured.
To recline the seatback, raise the
seatback tilt lever and gently lean
back to the desired position.To move the seatback forward, lean
forward with your back slightly clear
of the seatback and raise the lever.
After making adjustments, check
that the seatback is fully locked.
Suspension Adjustment
Avoid making any kind of contact
with the pointer on the scale. Doing
so may result in damage to the
pointer, preventing appropriate
weight adjustments from being
possible.
Before sitting on the seat, use the
knob to adjust the suspension to
suit your weight. Turn the knob
clockwise to move the pointer downthe scale and counterclockwise to
move it up the scale. The pointer
should be alongside your weight on
the scale.
The range of adjustment is
50-130 kg (110-290 lbs). If your
weight is outside this range, the
suspension may not be fully
effective. However, you will be able
to sit in the correct position for
driving.
Passenger
’s Seat/Center Seat
{Warning
Baggage must not be placed on
the center seat. If the baggage
falls on the floor when braking, it
may prevent the driver from
operating the pedals. You and
others could be seriously injured.

Seats and Restraints 33
Warning (Continued)
Do not use one seat belt for more
than one person. If worn by more
than one person, the seat belt
would not work effectively in a
collision or sudden stop.
Have seat belts inspected and,
if necessary, replaced by the
nearest dealer when the webbing
becomes frayed or worn and/or
when the buckle or other
mechanical parts fail to work
properly.
If your vehicle has been involved
in a collision, the seat belts worn
at the time may have lost their
original strength due to impact
even if they appear intact. These
seat belts must be inspected and,
if necessary, replaced by the
nearest dealer.(Continued)
Warning (Continued)
Be careful to keep the buckles
and retractors free of dust and
foreign matter. (This may jam the
retractor or damage the belt.)
Do not let the belt system
become damaged by the door
or seat.
Do not let the belt twist while it is
rewinding: it may cause the
retractor to jam so it will not
rewind further. If it is not fully
rewound, the belt cannot be
pulled out. Should the belt jam,
you may be able to release it by
working the belt in and out until
the belt rewinds far enough to
unlock. However, if the belt
remains jammed or other parts of
the restraint system do not work
properly, have your dealer
service it.(Continued)
Warning (Continued)
Wearing seat belts is a legal
requirement. All other passengers
must wear seat belts. The driver
is responsible not only for
wearing a seat belt himself/herself
but also for prompting all
passengers to wear their seat
belts. It is necessary, however, to
check with a doctor about the
appropriateness of a seat belt for
an expectant mother or a
passenger with a chest/abdominal
condition.
Three-Point Seat Belt

The shoulder belt should be
adequately positioned on your
shoulder but should not touch
your neck and/or face. The
shoulder belt could harm you in a

collision or sudden stop if it is in
contact with your neck and/
or face.
Every seat except the center seat
on your vehicle is equipped with a
three-point seat belt. The seat belt
extends or retracts freely if the
wearer moves slowly, but it locks
and restrains the occupant during
forward force caused by the
occupant's body following a strong
shock.To Fasten:
1. Sit on the seat in the correct driving position.
2. Pull out the seat belt holdingthe latch plate. After checking
that there are no twists in the
belt, insert the latch plate into
the buckle until it clicks. If the
retractor locks before the latch
plate reaches the buckle, let
the belt retract slightly, then
withdraw it slower than before.
3. To reduce the risk of slidingunder the belt during a
collision, position the belt
across your lap as low on your
hips as possible and adjust it to
a snug fit by pulling the
"shoulder" portion upward
through the latch plate.
The lap-shoulder belt is
designed to lock during a
sudden stop or impact. At other
times it should move freely.

Seats and Restraints 35
To Unfasten:
Push the button on the buckle. As
the belt automatically retracts, let it
be taken up slowly by holding on to
the latch plate until the belt is fully
retracted.
While being automatically retracted,
the seat belt could damage a
nearby window or interior trim
unless the latch plate is properly
held. Hold the latch plate to ensure
that the belt is taken up slowly.
Before closing the door, check that
the retracted seat belt is taut.
A slack belt could become trapped
in the door or seat rail.When the passenger's seat belt is
fully taken up (or not pulled out),
check that the stopper is holding the
belt in a fully taut state.
Emergency Locking Retractor
(ELR) Function
The three-point seat belts are
provided with an Emergency
Locking Retractor (ELR) function.
The ELR normally allows the seat
belt to move in and out freely as the
occupant moves. However, it locks
the seat belt to restrain the
occupant when a forward force
resulting from a collision or sudden
stop acts on the occupant.
The ELR also locks the seat belt
when the belt is pulled out quickly.
If this happens, allow it to retract
once and then pull it out slowly.
Seat Belt Use During
Pregnancy
{Warning
Unless the seat belt is correctly
worn, it may dig into the abdomen
in the event of hard braking or a
collision, harming not only the
expectant mother but also the
unborn child, putting them both in
danger of serious injuries or
death.

40 Seats and Restraints
Warning (Continued)
Any unrestrained child could be
injured by striking the vehicle's
interior or by ejection from the
vehicle during an accident or
driving maneuver. Never allow a
child to be held by another
occupant instead of being
properly restrained. If not properly
restrained, the child could strike
the vehicle interior or be crushed
by the person holding the child,
or by other occupants.
Be sure to follow all installation and
use instructions that come with any
child restraint system.
Child restraint systems are designed
to be secured in vehicle seats either
by the lap belt, or the lap portion of
the lap-shoulder belt at that seating
position. The child must also be
secured within the restraint by the
means provided by the child
restraint manufacturer. If the child or the child restraint is not properly
secured, the child risks personal
injury in the event of a collision.
Using a Lap Belt That Has No
Retractor
When securing a child restraint with
the center seat lap belt, pull the
excess webbing through the belt's
adjustment feature, then take these
steps:
.
Once installed, push and pull the
child restraint in all directions to
be sure it is secure. If it comes
loose, flip the end of the belt
with the adjustment feature over
before rebuckling.
. If the child restraint is still not
secure, use the outboard seating
position in the vehicle and
contact your dealer and the child
restraint manufacturer for help.
. Secure the child in the restraint
in accordance with the child
restraint manufacturer's
instructions.
Installation on Outboard Seat
A seat belt locking clip is required
for installation of a child restraint
system on the outboard seat of this
vehicle. A locking clip may usually
be obtained where child restraints
are sold, or by contacting your
dealer for assistance. Make sure the
locking clip is identical to the one
shown on this page. Until you have
the clip, use the child restraint
system only in the center seat.

{Warning
To help avoid personal injury or
death during a collision or sudden
maneuver, always thread both the
lap and shoulder belt through the
locking clip when securing a child
restraint on the outboard seat.
If the clip is not used or installed
properly, the child restraint may
move or tip over when your
vehicle turns or stops abruptly.
Secure the child restraint with the
lap belt portion (1) of the seat belt in
accordance with the restraint
manufacturer's instructions. Then
thread both the lap (1) and shoulder
belt (2) portions through the locking
clip. Push and pull the child restraint
in all directions to be sure it is
secure.

its loss.
Child Restraint with Top Tether
{Warning
We do not recommend using a
child restraint that requires the
use of a top tether. There is no
appropriate place to attach a top
tether anchor behind the seat in
this vehicle.
