cle owner (or the lessee if the
vehicle is leased) has been
given
 When officially requested by
the police, a court of law or a
government agency
 When it is to be used by
Toyota in a lawsuit
 When data is to be used
research purposes after pro-
cessing so that the data is not
tied to a specific vehicle or
vehicle owner
In addition to the above, Toyota
may disclose the data recorded
by the Toyota Safety Sense 3.0
to a third party in the following
situations:
 When separate consent of the
vehicle owner (or the lessee if
the vehicle is leased) has
been given. This includes sit-
uations when the user sub-
scribes to an individual
service which is provided by a
second party and uses vehi-
cle recorded data, where the
provider has obtained the
user’s consent for providing
data to a third-party
 When providing data to a
company involved in autono-
mous driving software, etc. for
the purpose of research and
development (technology,
product development, prod-
uct improvement, etc.) of
automated driving, advanced safety and map related tech-
nologies
 When providing image data
and position information to a
company involved in map cre-
ation, etc. for the purpose of
research and development
map related technologies
 When providing image data
and position information to a
local government for the pur-
pose of road maintenance,
etc.
 When providing processed
image data and position infor-
mation to traffic condition
communication individual ser-
vices
 When providing image data
from near a fire, or other area
that emergency services are
dispatched, to the fire depart-
ment of a local government
which has entered a separate
contract with Toyota
Image information recorded by the
vehicle can be erased by your
Toyota dealer.
The image recording function can
be disabled. However, if the function
is disabled, data from when systems
operate will not be available.
If you wish to stop the collection of
Toyota Safety Sense 3.0 data by the
Toyota servers for the purpose of
research and development and pro-
vision to individual services, contact
your Toyota dealer.

701-4. Theft deterrent system
1-4.Theft deterrent system
The indicator light flashes after
the power switch has been
turned to off to indicate that the
system is operating.
The indicator light stops flashing
after the power switch has been
turned to ACC or ON to indicate
that the system has been can-
celed.
■System maintenance
The vehicle has a maintenance-free
type immobilizer system.
■Conditions that may cause the
system to malfunction
●If the grip portion of the key is in
contact with a metallic object
●If the key is in close proximity to or
touching a key to the security sys-
tem (key with a built-in transpon-
der chip) of another vehicle
Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the hybrid sys-
tem from starting if a key
has not been previously
registered in the vehicle’s
on-board computer.
Never leave the keys inside
the vehicle when you leave
the vehicle.
This system is designed to
help prevent vehicle theft but
does not guarantee absolute
security against all vehicle
thefts.
Operating the system
NOTICE
■To ensure the system oper-
ates correctly
Do not modify or remove the sys-
tem. If modified or removed, the
proper operation of the system
cannot be guaranteed.

802-1. Plug-in hybrid system
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
when the hybrid system starts or
stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid battery (traction
battery), under the rear seats or
under the floor, when the hybrid
system is started or stopped.
●Sounds from the hybrid system
may be heard when the back door
is open.
●Sounds may be heard from the
transmission when the gasoline
engine starts or stops, when driv-
ing at low speeds, or during idling.
●Engine sounds may be heard
when accelerating sharply.
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Vibration may be felt when the
gasoline engine starts or stops.
●Sounds may be heard from near
the hybrid battery (traction battery)
in accordance with the operation
of the air conditioning system or
battery cooler. ( P.109)
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do not dispose of the
vehicle yourself.
In order to make EV mode or
AUTO EV/HV mode available,
charge the hybrid battery (trac-
tion battery) from an external
power source before using the
vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven.
However, if there is not enough
charge remaining, it is possible that
the vehicle cannot be driven in EV
mode or AUTO EV/HV mode or the
EV driving range will become
shorter.
■Refilling fuel
Plug-in Hybrid Electric Vehicles can
be driven using electricity charged
from an external power source.
However, as the gasoline engine is
used depending on the situation
(  P.79) even if in EV mode or
AUTO EV/HV mode, and the gaso-
line engine is provided on board as
a power source for driving in HV
mode, it is needed to refueling the
vehicle.
Check the fuel amount and refill
immediately when the fuel level
becomes low. ( P.279)
■If the vehicle is not used for a
long time
●The 12-volt battery may dis-
charge. In this event, charge the
12-volt battery. ( P.589)
In order to prevent the hybrid bat-
tery (traction batt ery) from becom-
ing extremely low in charge,
