CAUTION
When reinstalling the seat, observe
the following to prevent personal inju-
ry:
Do not reinstall the seat while the
vehicle is moving.
Be careful not to get your hands or
feet pinched in the seat.
Be careful not to hit the removed
seat against a person or drop it on
yourself.
After folding or installing the seat,
push it forward and backward to
make sure it is locked in position.
When reinstalling seats to their origi-
nal position, observe the following
precautions in order to prevent per-
sonal injury in a collision or s udden
stop:
Make sure the seat is securely
locked by pushing forward and rear-
ward on the top of the seatback or
by trying to pull up the edge of the
bottom cushion. Failure to do so
will prevent the seat belt from oper-
ating properly.
Make sure the seat belts are not
twisted or caught under the seat
and are arranged in their proper
position and are ready to use.
Install each seat in the same posi-
tion from which it was removed.
Failure to do so will prevent the
occupants from using seat belts
properly.
Do not reinstall the seat with its
back facing forward.
Make sure the seat is securely
locked in the proper position.
NOTICE
Do not carry the removed seat by
holding the seat position adjusting le-
ver.

SEATBACK ANGLE ADJUSTING STRAP
Lean forward and pull the strap for-
ward. Then lean back to the desired
angle and release the strap.
CAUTION
Align both seatbacks at the same
angle when a person sits in the
third seat center position. Other-
wise, the person cannot wear the
seat belt properly and this may
cause serious injuries in a collision.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
passengers are sitting up straight
and well back in the seats. If you
are reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen or
your neck may contact the shoulder
belt. In the event of a frontal colli-
sion, the more the seat is reclined,
the greater the risk of death or per-
sonal injury.BEFORE STOWING THIRD SEATS1. Stow the third seat belt buckles as shown in the illustration.
This prevents the belt buckles from falling
out when you stow the third seat.
NOTICE
The seat belt buckles must be stowed
before you stow the third seat.
2. To stow the center seat belt, pull it slightly out of its cover. It will auto-
matically roll back partway. Roll the
seat belt backwards as shown above
and insert it into the slot of its cov-
er. Make sure the tabs are securely
locked in the cover.
NOTICE
The seat belt must be stowed before
you fold the seatback.

CAUTION
Do not sit on the third seat when it
is in the stowed position as shown in
the illustration. It may cause an acci-
dent or severe injury in the event of
emergency braking or collision.
CAUTION
When stowing or returning the seat,
observe the following precautions in
order to prevent personal injury:
Make sure the seat is free of people
or luggage. Then, hold the seat and
slowly move it. Otherwise, people
may be injured or luggage may be
damaged if the seat hits them.
Be careful not to get your hands or
feet pinched in the seat.
Do not stow and return the seats
when you are inside the vehicle in
order to prevent pinching your
hands or feet in the seat. Be sure
to stow and return the seats from
outside the vehicle.
When returning seats to their original
position, observe the following pre-
cautions in order to prevent personal
injury in a collision or sudden stop:
Make sure the seat is securely
locked by pushing forward and rear-
ward on the top of the seatback or
by trying to pull up the edge of the
bottom cushion. Failure to do so
will prevent the seat belt from oper-
ating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.

Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
on page 121 in this Section for details.
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow the child to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. It does not provide sufficient
restraint.
Pregnant woman.
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatbacks too
much. The seat belts provide maxi-
mum protection when the seatbacks
are in the upright position. (Refer
to the seat adjustment instructions.)
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.

Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers—they may severely weaken the
belts. (See “Cleaning the interior”
on page 437 in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely.If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.
When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” on page 121 in this Section.) To
free the belt again, fully retract the belt
and then pull the belt out once more.CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed. It cannot
protect an adult occupant or your
child from injury.
