862. Fuel cell vehicle
MIRAI_OM_USA_OM62025U■
Fuel cell stack
●Depending on the usage environment, the fuel cell power output may
decline over the life of the vehicle. However, this will have almost no effect
on driving performance.
● In the following situations, the fuel cell power output may dec line faster than
normal driving:
• Extended use in areas with high amounts of dust
• Extended use in areas with high levels of sulfur (such as volc anoes or hot
springs).
• Extended use in areas with high concentrations of the following substances:
-Organic solvents, such as paint and thinner
-Amine-related materials such as ammonia
-Chlorinated substances such as salt air and snow-melting agent
However, upon returning to normal environment, the fuel cell po wer output
will recover over time.
• Salt water gets into the air cleaner filter It is recommended to replace the air cleaner filter and clean t he surround-
ing components. Have the vehicle inspected at your Toyota deale r
• The number of times the fuel cell system is started and stoppe d is exces-
sively high
• Extended use in freezing temperatures
■ Hydrogen tanks
●The hydrogen tanks are the high-pressure storage containers that are filled
with compressed hydrogen gas. The vehicle can be refueled at hy drogen
stations.
● The hydrogen tanks have an expiration date. Vehicles with expir ed hydro-
gen tanks must not be driven or refueled until the hydrogen tanks are
replaced. The expiration date is written on the inside of the fuel door. Con-
sult your Toyota dealer.
● When disposing of the hydrogen tanks or the hydrogen tank valve s, consult
your Toyota dealer for details.

MIRAI_OM_USA_OM62025U■
When the outside t emperature is low
The dehumidification function may not operate even when is pre ssed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
mode.

■ Changing the response of the swit ch for the air conditioning operation
panel
The reaction time, from when the switch is touched, can be changed by the
following operations.
The air conditioning cannot be operated during following operat ion.
Touch (decrease) and for about 3 seconds.
“01” ~ “05” is displayed in the monitor of the passenger side t empera-
ture.
Each time is touched, the reaction time switches over as follo ws.
01 (about 0.06 sec.) 02 (about 0.08 sec.) 03 (about 0.10 sec.) 
04 (about 0.12 sec.) 05 (about 0.14 sec.)
With the desired setting displayed, without switching over the screen by
performing touch operations for about 5 seconds, when the power
switch is turned off the configuration is complete.

Maintenance and care
WARNING
The motor compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the motor compartment
● Be careful not to touch the high-voltage parts or hydrogen-rela ted parts.
● Make sure that the “READY” indicator is off.
● Keep hands, clothing and tools away from the moving fans.
● Be careful not to touch the motor, inverter, radiator, etc., ri ght after driving
as they may be hot. Coolant and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and r ags, in the
motor compartment.
● Do not smoke, cause sparks or expose an open flame to the 12-volt bat-
tery. 12-volt battery fumes are flammable.
● Be extremely cautious when working on the 12-volt battery. It c ontains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and d amage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
● Never touch, disassemble, remove or replace the high-voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 325)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, flui d spray, etc.,
from getting in your eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive motor wear
due to dirt in the air.
