For safety and security
WARNING
●Do not hang coat hangers or
other hard objects on the coat
hooks. All of these items could
become projectiles and may
cause death or serious injury,
should the SRS curtain shield
airbags deploy.
●If a vinyl cover is put on the area
where the SRS knee airbag will
deploy, be sure to remove it.
●Do not use seat accessories
which cover the parts where the
SRS side airbags and SRS seat
cushion airbag inflate as they
may interfere with inflation of
the SRS airbags. Such acces-
sories may prevent the SRS
side airbags and SRS seat
cushion airbag from activating
correctly, disable the system or
cause the SRS side airbags and
SRS seat cushion airbag to
inflate accidentally, resulting in
death or serious injury.
●Do not strike or apply significant
levels of force to the area of the
SRS airbag components or the
front doors.
Doing so can cause the SRS
airbags to malfunction.
●Do not touch any of the compo-
nent parts immediately after the
SRS airbags have deployed
(inflated) as they may be hot.
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If the areas where the SRS air-
bags are stored, such as the
steering wheel pad and front
and rear pillar garnishes, are
damaged or cracked, have
them replaced by your Toyota
dealer.
●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 SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
●Installation, re moval, disassem-
bly and repair of the SRS air-
bags
●Repairs, modific ations, removal
or replacement of the steering
wheel, instrument panel, dash-
board, seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,
front door trims or front door
speakers
●Modifications to the front door
panel (such as making a hole in
it)
●Repairs or modifications of the
front fender, fr ont bumper, or
side of the occupant compart-
ment

521-1. For safe use
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.62)
●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.

●When securing some types of
child restraint s ystems 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.

For safety and security
There are air intake vents under
the front seats for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent
becomes blocked, the hybrid
battery (traction battery) may
overheat, leading to a reduction
in hybrid battery (traction bat-
tery) output.
WARNING
●If a fire occurs in the hybrid
vehicle, leave the vehicle as
soon as possible. Never use a
fire extinguisher that is not
meant for electric fires. Using
even a small amount of water
may be dangerous.
●If your vehicle needs to be
towed, do so with four wheels
raised. If the wheels connected
to the electric motor (traction
motor) are on the ground when
towing, the motor may continue
to generate electricity. This may
cause a fire. ( P.460)
●Carefully inspect the ground
under the vehicle. If you find
that liquid has leaked onto the
ground, the fuel system may
have been damaged. Leave the
vehicle as soon as possible.
■Hybrid battery (traction bat-
tery)
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly col-
lected, the follo wing may occur,
resulting in dea th or serious
injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
hybrid vehicle. If the hybrid bat-
tery is used out side of your
vehicle or modified in any way,
accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of an
accident is extremely high
because the person receiving the
vehicle may not be aware of these
dangers.
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
