MIRAI_OM_USA_OM62004UThe SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

WARNING
■
General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regard ing children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

441-1. For safe use
MIRAI_OM_USA_OM62004U
■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 inflator) 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 wi th 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 pass enger 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.

832. Fuel cell vehicle

Fuel cell system
MIRAI_OM_USA_OM62004U
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 illustrative purposes only and may differ from the
actual vehicle.

Power output restriction
When the power output is restricted, the vehicle may fail to accelerate or even
decelerate, even though the accelerator pedal is depressed. If a safe driving
speed cannot be maintained, stop the vehicle in a safe place away from the
traffic. This may be caused by the following conditions:
●The coolant temperature may be too high. This can be caused by driving
conditions such as repeated sudden acceleration and deceleration, continu-
ous driving on an incline, continuous driving at high altitudes with a high
load, etc. In such situations, the power output restriction indicator (amber) is
displayed on the main display, “High FC Temperature Reduced Power” is
displayed on the multi-information display, and the power output is
restricted. Once the coolant returns to normal temperature, the power out-
put will return to normal. ( P. 377)
● The remaining fuel may be low. After the low fuel warning indicator comes
on, the output power will be gradually restricted in order to extend the possi-
ble driving distance. Once getting to this point, the remaining driving dis-
tance possible is short. Immediately refill the vehicle with hydrogen.
● On cold days, the low fuel warning indicator comes on faster than usual and
the output power is restricted.
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult to hear for people around.
●In very noisy areas
● In wind or rain
Also, because the vehicle proximity notification system is located in the front
of the vehicle, it may be more difficult to hear from the rear of the vehicle
compared to the front.
■ Electromagnetic waves (EMF)
●High-voltage parts and cables in fuel cell vehicles have an electromagnetic
shielding configuration, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline-powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Traction battery
The traction battery has a limited service life. The lifespan of the traction bat-
tery can change according to driving style and driving conditions.

WARNING
■Tailpipe
●Do not directly touch the water or steam coming out of the tailpipe. Doing
so may cause low-temperature burns.
● The fuel cell vehicle generates wate r during power generation. The gener-
ated water discharged from the tailpipe is not suitable for drinking. Never
drink the water coming out of the tailpipe.
● You may notice a strange odor from the tailpipe for a while after the pur-
chase of a new vehicle or after an extended period of non-use, but this is
not a malfunction. Also, the odor is harmless but it may be unpleasant, so
do not breathe in the exhaust.
■ High-voltage and high-temperature precautions
This vehicle is equipped with a high-voltage system. Follow the instructions
below as high-voltages can cause severe burns and electric shock that may
result in death or serious injury.
●Never touch, disassemble, remove, or replace the high-voltage parts,
cables (orange), or connectors.
● The components inside the motor compartment will become hot during
operation. Be careful of both the high-voltage and high-temperature, and
always obey the warning labels on the vehicle.
●Never touch the service plugs that are
installed on the fuel cell stack and the
traction battery. The service plugs are
used to block high-voltages from the
fuel cell stack and the traction battery
during maintenance or repair at your
Toyota dealer.

WARNING
■Traction battery
●Never resell, transfer, or modify the traction battery. To prevent accidents,
traction batteries that have been removed from disposed vehicle are col-
lected through Toyota dealers. Do not dispose of the traction battery your-
self.
If the traction battery is not properly collected, the following may occur,
resulting in death or serious injury:
• The traction battery may be illegally disposed or dumped, and it is haz-
ardous to the environment. Additionally, someone may touch a
high-voltage part, resulting in an electric shock.
• The traction battery is intended to be used exclusively with your fuel cell vehicle. If the traction battery is used outside of your vehicle or modified
in any way, accidents, such as electric shock, heat generation, smoke
generation, ignition, explosion and electrolyte leakage may occur.
In particular, reselling or transferring the traction battery exposes the
receiving party to risks of accidents as they may not be aware of these
dangers. Make sure to inform them of the contents of this Owner’s Man-
ual.
● If your vehicle is disposed without the traction battery having been
removed, there is a danger of serious electric shock in case high-voltage
parts, cables, or their connectors are touched. When disposing of your
vehicle, the traction battery must be disposed by your Toyota dealer, or a
qualified service shop. If the traction battery is not disposed of properly, it
may cause electric shock that can result in death or serious injury.
NOTICE
■Traction battery air intake vent
●If the traction battery output decreases due to the entry of dust or debris,
foreign material, a warning message is shown on the multi-information dis-
play. Have the vehicle inspected at your Toyota dealer.
● Do not place objects where the air intake vent will be obstructed. This may
lead to a reduction in traction battery power output and damage.
● Clean the air intake vent regularly to prevent clogging.
● Do not allow water or objects to enter the air intake vent, as this may dam-
age the traction battery.
■ Traction Battery
Do not spill a large amount of water near the traction battery in the vehicle.
If water spills onto the traction battery, have the vehicle inspected at your
Toyota dealer.

P. 353
■ Operation of the power switch
When operating the power switch, one short, firm press is enough. If the
switch is pressed improperly, the fuel cell system may not start or the power
switch mode may not change. It is not necessary to press and hold the
switch.
■ Automatic P position selection function
●When the shift position is other than P, pressing the power switch with the
vehicle stopped completely will cause the shift position to change to P auto-
matically, and then the power switch will turn off.
● When turning the power switch off with the shift position other than P, firmly
depress the brake pedal and confirm that the shift position* has changed to
P before slowly releasing the brake pedal.
*: Even after the instrument panel display has been turned off, the shift
position indicator will continue to be displayed for several seconds.
■ If the shift control system malfunctions
The power switch will not be able to be turned off. In this occurs, the switch
can be turned off by applying the parking brake.
If the system malfunctions, have your vehicle serviced by your Toyota dealer
immediately.
■ If the smart key system has been deactivated in a customized setting
P. 436
WARNING
■When starting the fuel cell system
Always start the fuel cell system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the fuel cell system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the fuel cell system in an emergency
If you want to stop the fuel cell system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or press
it briefly 3 times or more in succession. ( P. 361)
However, do not touch the power switch while driving except in an emer-
gency. Turning the fuel cell system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.
