For safety and security
WARNING
●The SRS front passenger air-
bag deploys with considerable
force, and can cause death or
serious injury, especially if the
front passenger is very close to
the airbag. The front passenger
seat should be positioned as far
possible from the airbag with
the seatback adjusted so that
the passenger is sat upright.
●Improperly seated and/or
restrained infants and children
can be killed or seriously injured
by a deploying airbag. An infant
or child who is too small to use
a seat belt should be properly
secured using a child restraint
system. Toyota strongly recom-
mends that all infants and chil-
dren be placed in the rear seats
of the vehicle and properly
restrained. The rear seats are
safer for infants and children
than the front passenger seat.
(  P.51)
●Do not sit on the edge of the
seat or lean against the dash-
board.
●Do not allow a child to stand in
front of the SRS front passenger
airbag or sit on the lap of a front
passenger.
●Front seat occupants should
never hold items on their lap.
●Do not lean against the door,
roof side rail, or front, side, or
rear pillar.
●Do not allow anyone to kneel on
a seat toward the door or put
their head or hands outside the
vehicle.
●Do not attach anything to or
lean anything against areas
such as the dashboard or steer-
ing wheel pad.

421-1. For safe use
WARNING
●Do not attach anything to areas
such as the doors, windshield,
side windows, front or rear pil-
lars, roof side rails and assist
grips. (With the exception of the
speed limit label P.577)
●Do not use seat accessories
which cover the parts from
which the SRS airbags deploy,
as they may inte rfere with infla-
tion of the SRS airbags. Such
accessories may prevent the
SRS airbags from deploying
correctly, may disable the sys-
tem or cause the SRS airbags
to inflate unintentionally, possi-
bly resulting in death or serious
injury.
●Do not strike or apply significant
force to the SRS airbag system
components, front doors or their
surrounding area.
Doing so may cause the SRS
airbags to malfunction.
●Do not touch any components
of the SRS airbags 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 a part where an SRS airbag is
stored is damaged or cracked,
have it 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’s seat 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 unin-
tentionally, possibly leading to
death or serious injury.
●Removal, installation, disas-
sembly or repair of the SRS air-
bags
●Repair, removal or modification
of the following parts or their
surrounding
• Steering wheel

551-2. Child safety
1
For safety and security
A child restraint system for a
small child or baby must itself be
properly restrained on the seat
with the lap portion of the
lap/shoulder belt.
■Installing child restraint
system using a seat belt
(child restraint lock func-
tion belt)
Install the child restraint system
in accordance to the operation
WARNING
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, adjust the seat-
back angle to the most upright
position, move the seat to the
rearmost position, even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
●Do not allow the child to lean
his/her head or any part of
his/her body against the door or
the area of the seat, front or rear
pillars, or roof side rails from
which the SRS side airbags or
SRS curtain shield airbags
deploy even if the child is
seated in the child restraint sys-
tem. It is dangerous if the SRS
side and curtain shield airbags
inflate, and the impact could
cause death or serious injury to
the child.
●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.
●Use a child restraint system
suitable to the age and size of
the child and install it to the rear
seat.
●If the driver’s seat interferes
with the child restraint system
and prevents it from being
attached correctly, attach the
child restraint system to the
right-hand rear seat.
●Adjust the front passenger seat
so that it does not interfere with
the child restraint system.

Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically,
warming up is not necessary.The value displayed on the SOC
(State of Charge) gauge
(P.155) is estimated from the
following information.
 The amount of hybrid battery
(traction battery) charge cur-
rently remaining
 The electricity consumption
(the estimated distance that
EV driving is possible per unit
of electrical energy) based on
the recorded value
