CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
front passenger side seat belt sys-
tems. The front seat occupants can
be killed or seriously injured by an
inflating airbag if they do not wear
the available seat belts. During sud-
den braking just before a collision,
an unrestrained driver or front pas-
senger can move forward into direct
contact with or close proximity to
the airbag which may then deploy
during the collision. To obtain maxi-
mum protection in an accident, the
driver and all passengers in the ve-
hicle must wear their seat belts.
Wearing a seat belt during an acci-
dent reduces the chances of death
or serious injuries or being thrown
out of the vehicle. For instructions
and precautions concerning the seat
belt system, see ”Seat belts” in this
chapter.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by a deploying
airbag. An infant or child who is
too small to use a seat belt should
be properly secured using a child
restraint system. Toyota strongly
recommends that all infants and
children be placed in the rear seat
of the vehicle and properly re-
strained. The rear seat is the safest
for infants and children. For in-
structions concerning the installa-
tion of a child restraint system, see
”Child restraint” in this chapter.
Never put a rear−facing child re-
straint system on the front seat be-
cause the force of the rapid infla-
tion of the passenger airbag can
cause death or serious injury to the
child.

Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
and is put on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.
Never put a rear−facing child re-
straint system on the front seat. In
the event of an accident, the force
of the rapid inflation of the airbag
can cause death or serious injury if
a rear−facing child restraint system
is put on the front seat.
Unless it is unavoidable, do not put
a child restraint system on the
front seat.
A for war d−facing child restraint sys-
tem should be allowed to put on
the front seat only when it is un-
avoidable. Always move the seat as
far back as possible, because the
force of a deploying airbag could
cause death or serious injury to the
child.
Make sure that you have complied
with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured.
—Child restraint system
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with either the
lap belt or the lap portion of the lap/
shoulder belt. You must carefully con-
sult the manufacturer ’s instructions
which accompany your child restraint
system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer of the system. General di-
rections are also provided under the fol-
lowing illustrations.
The child restraint system should be
installed on the rear seat if your vehicle
is equipped with rear seats. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.

Never put a rear−facing child re-
straint system on the front seat. In
the event of an accident, the force
of the rapid inflation of the airbag
can cause death or serious injury if
a rear−facing child restraint system
is put on the front seat.

A for war d−facing child restraint sys-
tem should be allowed to put on
the front seat only when it is un-
avoidable. Always move the seat as
far back as possible, because the
force of a deploying airbag could
cause death or serious injury to the
child.
After installing the child restraint
system, make sure it is secured in
place following the manufacturer ’s
instructions. If it is not restrained
securely, it may cause death or se-
rious injury to the child in the
event of a sudden stop or accident.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident.
Your vehicle has anchors for securing the
top strap of a child restraint system. The
anchor nuts are welded beneath the sheet
metal to permit installation of an anchor
bracket for a child restraint system.
To install an anchor bracket, use an 8 mm
30 mm 1.25 mm coarse thread met-
ric bolt and 15 mm (0.6 in.) spacer. Note
that the bolts accompanying many child
restraint systems are not metric. You can
damage the anchor nuts on your vehicle
if you force bolts with different thread into
the anchor nuts.
For instructions about how to install the
anchor bracket, see ”Top strap anchors
and locations”.
If your child restraint system does not
provide any of the necessary parts, you
can purchase the following items from
your Toyota dealer.
CRS installation kit
(Part No. 04731−22012)—contains 1
bolt, 3 types of spacers and 1 locking
clip.

This child restraint is designed for use
only by children who weigh between 10
and 30 kg (22.1 and 66.1 lb.) and whose
height is between 85 and 127 cm (33.5
and 50.0 in.).
The child should be at least one year
old and must be capable of sitting up-
right alone and whose shoulder height
is at or below the maximum shoulder
height indicator. See indicator label be-
hind child seat pad.
It is important to use a rear−facing
child restraint until the child is about
a year old. A rear−facing restraint gives
the child’s head, neck and body the
support they would need in a crash.
See ”—Child restraint system” for more
information.
If your child’s shoulders are above the
indicator position, do not use the built−
in child restraint. Your child should use
the adult lap and shoulder belt.
According to accident statistics, children
are safer when properly restrained in the
rear seat than in the front seat.CAUTION
Make sure the child is securely re-
strained with the built−in child re-
straint. WARNING! Failure to follow
the manufacturer ’s instructions on the
use of this child restraint system can
result in your child striking the ve-
hicle’s interior during a sudden stop
or crash. Snugly adjust the belts pro-
vided with this child restraint around
your child.
When using the built−in child re-
straints, observe the following:
Use the belts of one child restraint
for only one child at a time. Do not
use the belts for two or more chil-
dren.
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seatback.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the child restraint belt sys-
tem.
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.
Replace the built−in child restraint
assembly if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
Do not use a separate child re-
straint system over the opened
built−in child restraint.
Do not use the adult lap and shoul-
der belt with the child restraint.
