For safety and security
Adjust the angle of the seat-
back so that you are sitting
straight up and so that you do
not have to lean forward to
steer. ( P.133)
Adjust the seat so that you
can depress the pedals fully
and so that your arms bend
slightly at the elbow when
gripping the steering wheel.
( P.133)
Lock the head restraint in
place with the center of the
head restraint closest to the
top of your ears. ( P.140)
Wear the seat belt correctly.
( P.29)
WARNING
■Before driving
●Check that the floor mat is
securely fixed in the correct
place with all the provided
retaining hooks (clips). Be espe-
cially careful to perform this
check after cleaning the floor.
●With the hybrid system stopped
and the shift lever in P, fully
depress each pedal to the floor

For safety and security
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.
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.
Fastening and releasing
the seat belt (except for
the rear center seat)

WARNING
■Front passenger occupant
classification system precau-
tions
Observe the following precautions
regarding the front passenger
occupant classification system.
Failure to do so may cause death
or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s
seat belt plate has not been left
inserted into the buckle before
someone sits in the front pas-
senger seat.

WARNING
●Make sure the “AIR BAG OFF”
indicator light is not illuminated
when using the seat belt
extender for the front passenger
seat. If the “AIR BAG OFF” indi-
cator light is illuminated, discon-
nect the extender tongue from
the seat belt buckle, and recon-
nect the seat belt. Reconnect
the seat belt extender after
making sure the “AIR BAG ON”
indicator light is illuminated. If
you use the seat belt extender
while the “AIR BAG OFF” indi-
cator light is illuminated, the
SRS airbags for the front pas-
senger will not activate, which
could cause death or serious
injury in the ev ent of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. seatback pocket).
●Do not put weight on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.
●Do not recline t he front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “AIR BAG OFF” indi-
cator light to be illuminated,
which indicates that the SRS
airbags for the front passenger
will not activate in the event of a
severe accident. If the seatback
touches the rear seat, return the
seatback to a position where it
does not touch the rear seat.
Keep the front passenger seat-
back as upright as possible
when the vehicle is moving.
Reclining the seatback exces-
sively may lessen the effective-
ness of the seat belt system.
●If an adult sits i n the front pas-
senger seat, the “AIR BAG ON”
indicator light i s illuminated. If
the “AIR BAG OFF” indicator is
illuminated, ask the passenger
to sit up straight, well back in
the seat, feet on the floor, and
with the seat belt worn correctly.
If the “AIR BAG OFF” indicator
still remains illumi nated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger seat fully rearward.
●When it is unavoidable to install
a forward-facing child restraint
system on the front passenger
seat, install the child restraint
system on the front passenger
seat in the proper order.
(  P. 5 5 )
●Do not modify or remove the
front seats.
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light m ay come on to
indicate a malfu nction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.
