CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
●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 sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. (P. 120)
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s air-
bag system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the driver’s airbag may not
activate correctly in a collision, resulting
in death or serious injury in the event of
collision. Be sure to wear the seat belt
with the seat belt extender.

CAUTION
■Child restraint precautions
●A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if “AIR BAG OFF” indicator light is illuminated,
because the front passenger airbag could inflate with considerable speed
and force. Otherwise, the child may be killed or seriously injured.
●Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or accident.
●Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat, front pillar or roof side rail from
which the side airbags or curtain shield airbags deploy even if the child is
seated in the child restraint system. It is dangerous if the side airbags and
curtain shield airbags inflate, and the impact could cause death or serious
injury to the child.
●Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or accident.

CAUTION
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the
belt becomes twisted around a child’s neck, it will not be possible to pull the
belt out leading to choking or other serious injuries that result in death. If this
occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the restraint unsecured in the passenger compart-
ment.
●If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the trunk. This will prevent it from injuring
passengers in the event of a sudden stop, sudden swerve or accident.

Installing child restraints
Follow the child restraint system manufacturer’s instructions. Firmly
secure child restraints to the outboard rear seats using the LATCH
anchors or a seat belt. Attach the top tether strap when installing a
child restraint.
The lap/shoulder belt can be used if your child restraint system is
not compatible with the LATCH (Lower Anchors and Tethers for Chil-
dren) system.
Child restraint LATCH anchors
LATCH anchors are provided
for the outboard rear seats.
(Buttons displaying the loca-
tion of the anchors are
attached to the seats.)
Seat belts equipped with a
child restraint locking mecha-
nism (ALR/ELR belts except
driver’s seat belt) (P. 68)
Anchor bracket
(for top tether strap)
Anchor brackets are provided
for all rear seats.

Before driving
AVALON_U (OM41428U)While pushing the child restraint
system down into the rear seat,
allow the shoulder belt to retract
until the child seat is securely in

After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■Forward-facing Convertible seat
Place the child restraint system
on the seat facing the front of the
vehicle.
Run the seat belt through the
child restraint system and insert
the plate into the buckle. Make
sure that the belt is not twisted.

130 1-7. Safety information
AVALON_U (OM41428U)Fully extend the shoulder strap
and then allow it to retract
slightly into the ALR lock mode.
Lock mode allows the seat belt to
retract only.
While pushing the child restraint
system into the rear seat, allow
the shoulder belt to retract until
the child restraint system is
securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
If the child restraint has a top tether strap, the top tether strap
should be latched onto the top tether strap anchors. (P. 132)
