buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. (P.31)
■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may spring
up due to the rebound of the seat
cushion. Release the buckle while
holding down the child restraint
system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●Ensure that the belt and plate
are securely locked and the
seat belt is not twisted.
●Shake the child restraint system
left and right, and forward and
backward to ensure that it has
been securely installed.
●After securing a child restraint
system, never adjust the seat.
●When a booster seat is
installed, always ensure that the
shoulder belt is positioned
across the center of the child’s
shoulder. The belt should be
kept away from the child’s neck,
but not so that it could fall off the
child’s shoulder.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.

WARNING
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting se at belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, mo ve to a differ-
ent position. Failure to do so
may result in death or serious
injury.
■When installing a booster
seat
To prevent the belt from going
into ALR lock mode, do not fully
extend the shoulder belt. ALR
mode causes the belt to tighten
only. This could cause injury or
discomfort to the child. ( P.33)
■Do not use a seat belt
extender
If a seat belt extender is used
when installing a child restraint
system, the seat belt will not
securely hold th e child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.

■Laws and regulations pertain-
ing to anchors
The LATCH system conforms to
FMVSS225 or CMVSS210.2.

WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●When using the LATCH
anchors, be sure that there are
no foreign objects around the
anchors and that the seat belt is
not caught behind the child
restraint system.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.
●Never attach two child restraint
system attachments to the
same anchor. In a collision, one
anchor may not be strong
enough to hold two child
restraint system attachments
and may break.
If the LATCH anchors are
already in use, use the seat belt
to install a child restraint system
in the center seat.
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting seat belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, move to a differ-
ent position. Failure to do so
may result in death or serious
injury.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.

■Automatic Collision Notifi-
cation
In case of either airbag deploy-
ment or severe rear-end colli-
sion, the system is designed to
automatically call the response
center. The responding agent
receives the vehicle’s location
and attempts to speak with the
vehicle occupants to assess the
level of emergency. If the occu-
pants are unable to communi-
cate, the agent automatically
treats the call as an emergency,
contacts the nearest emer-
gency services provider to
describe the situation, and
requests that assistance be sent
to the location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety
Connect can work with local
authorities to assist them in
locating and recovering the
vehicle. After filing a police
report, call the Customer Experi-
ence Center at 1-800-331-4331
in the United States, 1-877-855-
8377 in Puerto Rico or 1-888-
869-6828 in Canada, and follow
the prompts for Safety Connect
to initiate this service.
In addition to assisting law
enforcement with recovery of a
stolen vehicle, Safety-Connect-
equipped vehicle location data
may, under certain circum-
stances, be shared with third
parties to locate your vehicle.
Further information is available
at Toyota.com in the United
States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
■Emergency Assistance But-
ton (“SOS”)
In the event of an emergency on
the road, push the “SOS” button
to reach the Safety Connect
response center. The answering
agent will determine your vehi-
cle’s location, assess the emer-
gency, and dispatch the
necessary assistance required.
If you accidentally press the “SOS”
button, tell the response-center
agent that you are not experiencing
an emergency.
