MIRAI_OM_USA_OM62023U
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflat\
or) as
well as the front seats, parts of the front and rear pillars, and roof side rails,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event of
a severe rear-end collision, the system is designed to send an emergency
call to the response center, notifying them of the vehicle’s location (without
needing to push the “SOS” button) and an agent will attempt to speak with
the occupants to ascertain the level of emergency and assistance required.
If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to dispatch the necessary emergency
services. ( →P. 299)
■ SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
● The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
● The SRS seat cushion airbag on the front passenger seat will not operate if
the occupant is not wearing a seat belt.

SRS airbag deployment conditions (S RS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event 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] vehi\
cle
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 vehicle rollover.
● The SRS side and curtain shield airbags may also deploy in the event of a
severe frontal collision.
■ Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS side and curtain shield airbags may also
deploy if a serious impact occurs to the underside of your vehicle. Some
examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations 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 detects the conditions of the front
passenger seat and activates or deactivates the devices for the
front passenger.

Fuel cell system
MIRAI_OM_USA_OM62023U
The fuel cell vehicle has high-voltage components (about 650 V maxi-
mum) such as a fuel cell stack, traction battery, power control unit,
high-voltage cables (which are distinguished from low-voltage cables
by their orange covers), electric motor (traction motor), etc., and high-
temperature parts such as the radiator for cooling. Pay attention to all
warning labels attached to the vehicle.
This diagram is for illust rative purposes only and may differ from the
actual vehicle.

Fuel cell system
MIRAI_OM_USA_OM62023U
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 warn ing 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 pro\
cedure 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. 9 0
● 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 cannot be
started, refuel the vehicle until the low fuel level warning light ( →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. 260).
◆Air conditioning system on/off
● Turn off the air conditioning sy stem operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temper ature is high, use the recircu-
lated air mode. This decreas es 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. 268).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning system
turned on.
◆Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tire s have more rolling friction and their use on
dry roads lead to poor fuel econom y. Use tires that are appropriate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel ec onomy. Installing a large roof rack will also
reduce fuel economy.

Conditions affecting operation
The smart key system uses weak radio waves. In the following situations, 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 station, large dis-
play, airport or other facility that generates strong radio waves 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 wireless 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 electronic
devices
