For safety and security
1-4.Theft deterrent system
The indicator light flashes after
the power switch has been
turned 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
■Certification
 P.543
Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the fuel cell
system 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.

trol.
 Turn the power switch to ACC
or ON, or start the fuel cell
system. (The alarm will be
deactivated or stopped after a
few seconds.)
■System maintenance
The vehicle has a maintenance-free
type alarm system.
■Triggering of the alarm
The alarm may be triggered in the
following situations:
(Stopping the alarm deactivates the
alarm system.)
●For Canada: The doors are
unlocked using the mechanical
key.
●For Canada: The trunk is opened
using the mechanical key.
●A person inside the vehicle opens
a door, the trunk or hood, or
unlocks the vehicle.
●The 12-volt battery is recharged or
replaced when the vehicle is
locked. ( P.473)
■Alarm-operated door lock
In the following cases, depending
on the situation, the door may auto-
matically lock to prevent improper
entry into the vehicle:
●When a person remaining in the
vehicle unlocks the door and the
alarm is activated.
●While the alarm i s activated, a
person remaining in the vehicle
unlocks the door.
■Customization
Some functions can be customized.

Fuel cell system
in order to warn people nearby
of the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
23 mph (37 km/h).
■How to hear the warning
In the following ca ses, the acoustic
vehicle alerting system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the acoustic vehicle alerting
system is installed on the front of the
vehicle, it may be m ore difficult to
hear from the rear of the vehicle
compared to the front.
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation to enhance
fuel economy. For details about
Predictive efficient drive, refer to
“NAVIGATION AND MULTIME-
DIA SYSTEM OWNER’S MAN-
UAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the refer-
ence operation range of the ECO Accelerator Guid-
ance (
P.102) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.
 The regenerative braking
force will be increased
according to the driving condi-
tions to more efficiently
charge the traction battery
after the accelerator pedal is
released.
■Predictive SOC* control
The following types of controls
are performed based on data
such as road information during
route guidance by the naviga-
tion system to help ensure that
the vehicle effici ently uses elec-
tricity.
 When there is a long downhill
slope along the route, the sys-
tem reduces the traction bat-
tery level before reaching the
slope to help ensure charging
capacity for regenerative
braking while traveling down-
hill.

■Driving in the rain
●Drive carefully when it is raining,
because visibility will be reduced,
the windows may become fogged-
up, and the road will be slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.102)
Eco-friendly driving may be
achieved more easily by staying
within the zone of Eco acceleration.
Also, by staying w ithin the zone of
Eco acceleration, i t will be easier to
obtain a good Eco score.
●When starting off:
Gradually depress the accelerator
pedal to stay withi n the zone of Eco
acceleration and accelerate to the
desired speed. By refraining from
excessive acceleration, a good eco
start score will be obtained.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
while staying within the zone of Eco
acceleration. By staying within the
zone of Eco acceleration, a good
eco cruise score will be obtained.
●When stopping:
By starting to release the accelera-
tor pedal early before decelerating,
a good eco stop score will be
obtained.
■Restraining the fuel cell system
output (Brake Override System)
●When the accelera tor and brake
pedals are depressed at the same
time, the fuel cell system output
may be restrained.
●A warning message is displayed
on the multi-information display
and head-up display (if equipped)
while the system is operating.
(  P.446)
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking
brake system
Your vehicle has a drum-in-disc type
parking brake system. This type of
brake system needs bedding-down
of the brake shoes periodically or
whenever the par king brake shoes
and/or drum are replaced. Have
your Toyota dealer perform the bed-
ding down operation.
■Operating your v ehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.
(  P.483)

tions.
Failure to do so may result in
death or serious injury.

■Fuel types
 P.483
■Notes on fueling
●Fueling will not be possible if the
pressure inside the vehicle’s
hydrogen tanks is higher than the
supply pressure of the hydrogen
station. If the hydrogen tanks are
more than half full, the vehicle will
be unable to fuel at a H35 dis-
penser. A hydrogen station with a
H70 dispenser (supply pressure of
10150 psi) [70 MPa, 714 kgf/cm
2,
700 bar] is necessary to com-
pletely fill hydrogen tanks.
●If the fueling cannot be completed
due to trouble with the station
equipment, call the number indi-
cated on the equipment.
Opening the fuel door
Fuel with compressed
hydrogen gas only at hydro-
gen stations.
Fuel at hydrogen stations
conforming with the Society
of Automotive Engineers
(SAE) J2601 fueling proto-
col or laws that may super-
sede such SAE protocols.
Refer to the Mirai Station

(for Canadian owners).
 Observe any notices or
instructions shown at hydro-
gen stations.
The filling time and amount
of fuel may depend on out-
side temperature and the
equipment at that hydrogen
station.
Vehicles with expired hydro-
gen tanks must not be used.
Check P.81 to learn how
and when to check the expi-
ration. Consult your Toyota
dealer.
