■Child seat belt usage
The seat belts of your vehicle were
principally designed for persons of
adult size.
●Use a child restraint system
appropriate for the child, until the
child becomes large enough to
properly wear the vehicle’s seat
belt. ( P. 5 3 )
●When the child becomes large
enough to properl y wear the vehi-
cle’s seat belt, follow the instruc-
tions regarding seat belt usage.
(  P. 2 9 )
■Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Toy-
ota dealer free of charge.
WARNING
●Inspect the seat belt system
periodically. Check for cuts,
fraying, and loose parts. Do not
use a damaged sea t belt until it
is replaced. Damaged seat belts
cannot protect an occupant
from death or serious injury.
●Ensure that the belt and plate
are locked and the belt is not
twisted.
If the seat belt does not function
correctly, immediately contact
your Toyota dealer.
●Replace the seat assembly,
including the belts, if your vehi-
cle has been involved in a seri-
ous accident, even if there is no
obvious damage.
●Do not attempt to install,
remove, modify, disassemble or
dispose of the seat belts. Have
any necessary repairs carried
out by your Toyota dealer. Inap-
propriate handling may lead to
incorrect operation.
Correct use of the seat
belts
WARNING
■Using a seat belt extender
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking, sudden
swerving or an accident.
Failure to do so may cause death
or serious injury.

1 To fasten the seat belt, push the plate into the buckle until
a click sound is heard.
2 To release the seat belt,
press the release button .
If the seat belt cannot be pulled out
of the retractor, firmly pull the belt
and release it.
■Emergency locking retractor
(ELR)
The retractor will lock the belt during
a sudden stop or on impact. It may
also lock if you lean forward too
quickly. A slow, easy motion will
allow the belt to extend so that you
can move around fully.
■Automatic locking retractor
(ALR)
When a passenger’s shoulder belt is
completely extended and then
retracted even slightly, the belt is
locked in that position and cannot
be extended. This feature is used to
hold the child restraint system
(CRS) firmly. To free the belt again,
fully retract the belt and then pull the
belt out once more. ( P. 5 3 )
■After using the seat belts on the
outboard rear seats
Stow the seat belt buckle in the
pockets.
WARNING
●Do not wear the seat belt
extender if you can fasten the
seat belt without the extender.
●Do not use the seat belt
extender when installing a child
restraint system because the
belt will not securely hold the
child restraint system, increas-
ing the risk of death or serious
injury in the event of an acci-
dent.
●The personalized extender may
not be safe on another vehicle,
when used by another person,
or at a different seating position
other than the one originally
intended.

Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the front seats,
parts of the front and rear pillars,
and roof side rails, may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. ( P. 7 9 )
●All of the doors will be unlocked.
( P.114)
●The brakes and st op lights will be
controlled automatically. ( P.375)
●The interior lights will turn on auto-
matically. ( P.412)
●The emergency flashers will turn
on automatically. ( P.494)
●For Safety Connect subscribers, if
any of the following situations
occur, the system is designed to
send an emergency call to the response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (

• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e corresponding
to an approximately 12 - 18 mph
[20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will
be considerably higher in the follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform
on impact
• If the vehicle is involved in an

WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so m ay 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.
●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.
●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. Fa ilure to do so
may result in death or serious
injury.

For safety and security
WARNING
●When installing a child restraint
system in the rear center seat,
adjust both seat cushions to the
same position and align both
seatbacks at the same angle.
Otherwise, the child restraint
system cannot be securely
restrained and t his may cause
death or serious injuries in the
event of sudden braking, sud-
den swerving or an accident.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.
■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.31,
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 the 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.

For safety and security
There are an air intake vents
under the rear seat for the pur-
pose of cooling the hybrid bat-
tery (traction battery). If the
vents becomes blocked, the
hybrid battery (traction battery)
input and output may be
reduced. When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
