SRS airbag deployment conditions (SRS side and curtain shield a irbags)
● The SRS side and curtain shield airbags will deploy in the even t of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/ h]).
● The SRS curtain shield airbags will deploy in the event of vehi cle rollover.
● The SRS side and curtain shield airbags may also deploy in the event of a
severe frontal collision.
■ Conditions under which the SRS ai rbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS side and curtain shield airbags m ay also
deploy if a serious impact occurs to the underside of your vehi cle. Some
examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situat ions shown
in the illustration. ● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.

Front passenger occupant classification
system
Your vehicle is equipped with a front passenger occupant classi -
fication system. This system det ects the conditions of the front
passenger seat and activates or deactivates the devices for the
front passenger.

Fuel cell system
MIRAI_OM_USA_OM62025U
The fuel cell vehicle has high-voltage components (about 650 V m axi-
mum) such as a fuel cell stack, traction battery, power control unit,
high-voltage cables (which are di stinguished from low-voltage cables
by their orange covers), electric motor (traction motor), etc., and high-
temperature parts such as the radiator for cooling. Pay attenti on to all
warning labels attached to the vehicle.
This diagram is for illustrative purposes only and may differ f rom the
actual vehicle.

Fuel cell system
MIRAI_OM_USA_OM62025U
There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■If a warning light comes on, a warning message is displayed, or the
12-volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start procedure is
repeated, contact your Toyota dealer.
■ If “Hydrogen Leakage Detected Visit Your Dealer” is displayed on the
multi-information display
A small amount of hydrogen gas may be leaking. Have the vehicle inspected
immediately at the nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer” is displayed on the multi -informa-
tion display
● Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
P. 90
● The air conditioning system will shut off automatically.
■ Running out of fuel
When the vehicle has run out of fuel and the fuel cell system c annot be
started, refuel the vehicle until the low fuel level warning li ght (P. 371) turns
off before trying to restart. It may not be able to restart if the refueled amount
is too low (less than about 2.7 lb. [1.2 kg]).

◆Using Eco drive mode
Using Eco drive mode (P. 181) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode ( P. 2 5 8 ) .
◆Air conditioning system on/off
● Turn off the air conditioning system operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temperature is high, use the recircu -
lated air mode. This decreases the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize the need for cabin heating ( P. 266).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning syst em
turned on.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tires have mo re rolling friction and their use on
dry roads lead to poor fuel economy. Use tires that are appropr iate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel economy. Installing a large roof rack wil l also
reduce fuel economy.

Power restriction indicator
Blue: The fuel cell system output power is restricted, because the
coolant temperature is low.
Amber: The fuel cell system output power is restricted, because the
coolant temperature is high.
Outside temperature
Displays the outside temperature within the range of -40°F (-40 °C)
to 122°F (50°C).
Low outside temperature indicator flashes when the ambient tem-
perature is 37°F (3°C) or lower.
Driving range distance
Displays the estimated maximum distance that can be driven with
the quantity of fuel remaining. • Displays the possible driving d istance computed from the fuel
consumption studied f rom the driving history and the current
remaining amount of fuel. The ac tual possible driving distance
may differ as fuel consumpti on changes, depending on driving
environment (weather, traffic, etc.) and conditions (sudden acc el-
eration, air conditioning, etc.).
• When only a small amount of fuel is added to the hydrogen tanks, the display may not be updated.
Speedometer
Displays the vehicle speed.
Odometer and trip meter
Odometer:
Displays the total distance the vehicle has been driven.
Trip meter:
Displays the distance the vehicl e has been driven since the met er
was last reset.
Trip meters “A” and “B” can be used to record and display diffe rent
distances independently.
Distance after start:
Displays the distance driven afte r the fuel cell system was started.
Blank:
A blank is displayed.

Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and immobilizer
system from operating properly. (Ways of coping: P. 398)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wirele ss commu-
nication devices
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to the
rear window
● When the electronic key is placed near a battery charger or ele ctronic
devices
