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 2 )
■After using the rear center seat
belt
Stow seat belt buckle in the pocket.
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.
NOTICE
■When using a seat belt
extender
When releasing the seat belt,
press on the buckle release but-
ton on the extender, not on the
seat belt.
This helps prevent damage to the
vehicle interior and the extender
itself.

anchor down while pressing
the release button .
2 Push the seat belt shoulder
anchor up while pressing the
release button .
Move the height adjuster up and
down as needed until you hear a
click.
The pretensioners help the seat
belts to quickly restrain the
occupants by retracting the seat
belts when the vehicle is sub-
jected to certain types of severe
frontal or side collision or a vehi-
cle rollover.
The pretensioners do not activate
in the event of a minor frontal
impact, a minor s ide impact or a
rear impact.
■Replacing the belt after the pre-
tensioner has been activated
If the vehicle is involved in multiple
collisions, the pretensioner will acti-
vate for the first collision, but will not
activate for the second or subse-
quent collisions.
■PCS-linked seat belt preten-
sioner control
If the PCS (Pre-Collision System)
determines that the possibility of a
collision with a vehi cle is high, the
seat belt pretensioners will be pre-
pared to operate.

WARNING
■Adjustable shoulder anchor
Always make sure the shoulder
belt is positioned across the cen-
ter of your shoulder. The belt
should be kept away from your
neck, but not falling off your shoul-
der. Failure to do so could reduce
the amount of protection in an
accident and cause death or seri-
ous injuries in the event of a sud-
den stop, sudden swerve or
accident.

For safety and security
When the vehicle speed
reaches approximately 12 mph
(20 km/h) or higher, the seat
belts will retract slightly to
remove any slack. If the system
determines that a collision is
unavoidable, the front seat belts
will retract before the collision.
Refer to “Toyota Teammate
Advanced Drive OWNER’S
MANUAL” for details.
■Active Assist
A motor sound may be heard when
a front seat belt is released or a
front door is opened. This does not
indicate a malfunction.
■Customization
Some functions can be customized.
(  P.512)
WARNING
■Seat belt pretensioners
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.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the seat belt pretensioner
for the front passenger’s seat
may not activate in the event of
a collision.
●If the pretensioner has acti-
vated, the SRS warning light will
come on. In that case, the seat
belt cannot be used again and
must be replaced at your Toyota
dealer.

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 fuel cell system will be
stopped and hydr ogen supply will
be stopped fro m the hydrogen
tank valves. ( P. 8 9 )
●All of the doors will be unlocked.
( P.128)
●The brakes and st op lights will be
controlled automatically. ( P.323)
●The interior lights will turn on auto-
matically. ( P.357)
●The emergency flashers will turn
on automatically. ( P.446)
●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. (
P. 6 5 )
• 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:

371-1. For safe use
Owners Manual_USA_M62064_en
1
For safety and security
• 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 underride collision, such as a colli-
sion in which the front of the vehi-
cle underrides, or goes under, the
bed of a truck
●Depending on the type of collision,
it is possible that only the seat belt
pretensioners will activate.
●The SRS front airbags for the front
passenger will not activate if there
is no passenger sitting in the front
passenger seat. However, the
SRS front airbags for the front
passenger may de ploy if luggage
is put in the seat, even if the seat
is unoccupied.
■SRS airbag deployment condi-
tions (SRS side and curtain
shield airbags)
●The SRS side and curtain shield
airbags will deploy i n the event of
an impact that exceeds the set
threshold level (the level of force
corresponding to the impact force
produced by an approximately
3300 lb. [1500 kg] vehicle colliding
with the vehicle cabin from a
direction perpendicular to the
vehicle orientation at an approxi-
mate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags
may deploy in the event of a
severe side collision.
●Both SRS curtain shield airbags
will deploy in the event of vehicle
rollover.
●Both SRS curtain shield airbags
may also deploy in the event of a
severe frontal collision.
■Conditions under which the
SRS airbags may deploy
(inflate), other t han a collision
The SRS front airbags and SRS
side and curtain shield airbags may
also deploy if a serious impact occurs to the underside of your vehi-
cle. Some examples are shown in
the illustration.
●Hitting a curb, edge of pavement
or hard surface
●Falling into or jumping over a deep
hole
●Landing hard or falling
The SRS curtain shield airbags may
also deploy under the situations
shown in the illustration.
●The angle of vehicle tip-up is mar-
ginal.
●The vehicle skids and hits a curb
stone.
■Types of collisions that may not
deploy the SRS airbags (SRS
front airbags)
The SRS front airbags do not gener-
ally inflate if the vehicle is involved
in a side or r ear collision, if it rolls
over, or if it is involved in a low-
speed frontal collision. But, when-
ever a collision o f any type causes
sufficient forward deceleration of the
vehicle, deploym ent of the SRS
front airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover

■Types of collisions that may not
deploy the SRS airbags (SRS
side and curtain shield airbags)
The SRS side and curtain shield air-
bags may not activate if the vehicle
is subjected to a c ollision from the
side at certain angl es, or a collision
to the side of the vehicle body other
than the passenger compartment.
●Collision from the s ide to the vehi-
cle body other than the passenger
compartment
●Collision from the s ide at an angle
The SRS side airbags do not gener-
ally inflate if the vehicle is involved
in a frontal or rear c ollision, if it rolls
over, or if it is involved in a low-
speed side collision.
●Collision from the front
●Collision from the rear
●Vehicle rollover
The SRS curtain shield airbags do
not generally inflate if the vehicle is involved in a rear collision, if it
pitches end over en
d, or if it is
involved in a low- speed side or low-
speed frontal collision.
●Collision from the rear
●Pitching end over end
■When to contact your Toyota
dealer
In the following ca ses, the vehicle
will require inspecti on and/or repair.
Contact your Toyota dealer as soon
as possible.
●Any of the SRS airbags have
been inflated.
●The front of the vehicle is dam-
aged or deformed, or was
involved in an accident that was
not severe enough to cause the
SRS front airbags to inflate.
●A portion of a door or its surround-
ing area is damaged, deformed or
has had a hole made in it, or the
vehicle was involved in an acci-
dent that was not severe enough
to cause the SRS side and curtain
shield airbags to inflate.

For safety and security
●The pad section of the steering
wheel, dashboard near the front
passenger airbag o r lower portion
of the instrument panel is
scratched, cracked, or otherwise
damaged.
●The surface of the seats with the
side airbag is scratched, cracked,
or otherwise damaged.
●The portion of the front pillars, rear
pillars or roof side rail garnishes
(padding) containing the SRS cur-
tain shield airbags inside is
scratched, cracked, or otherwise
damaged.
WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death
or serious injury.
●The driver and all passengers in
the vehicle must wear their seat
belts properly.
The SRS airbags are supple-
mental devices to be used with
the seat belts.
●The SRS driver airbag deploys
with considerable force, and
can cause death or serious
injury especially if the driver is
very close to the airbag.
The National Highway Traffic
Safety Administr ation (NHTSA)
advises: Since the risk zone for
the driver’s airbag is the first 2 - 3
in. (50 - 75 mm) of inflation, plac-
ing yourself 10 in. (250 mm) from
your driver airbag provides you
with a clear margin of safety. This
distance is measured from the
center of the steering wheel to
your breastbone. If you sit less
than 10 in. (250 mm) away now,
you can change you r driving posi-
tion in several ways:
• Move your seat to the rear as far as you can while still reach-
ing the pedals comfortably.
