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 decline faster than
normal driving:
• Extended use in areas with high amounts of dust
• Extended use in areas with high levels of sulfur (such as volcanoes 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 power output
will recover over time.
• Salt water gets into the air cleaner filter It is recommended to replace the air cleaner filter and clean the surround-
ing components. Have the vehicle inspected at your Toyota dealer
• The number of times the fuel cell system is started and stopped 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 hydrogen
stations.
● The hydrogen tanks have an expiration date. Vehicles with expired 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 valves, consult
your Toyota dealer for details.

Fuel cell system
MIRAI_OM_USA_OM62004U■
Fuel cell stack coolant
●Fuel cell stack coolant uses a specifically-designed fluid with high electrical
insulation properties, in order to safely cool the high-voltage fuel cell stack.
● Never add water or other coolants to the fuel cell stack cooling system, as
they will cause permanent damage.
● Consult your Toyota dealer for replenishing or changing the fuel cell stack
coolant.
■ Ion filter
●An ion filter is installed in the coolant lines for the fuel cell stack, in order to
maintain the normal insulation properties of the coolant.
● It is necessary to periodically change the ion filter. ( P. 378) Contact your
Toyota dealer for this periodic maintenance.
■ Tailpipe
●When the power switch is turned off and the fuel cell system is stopped
(P. 173) after driving, exhaust water is discharged. Be careful when stand-
ing behind the vehicle to avoid dripping or spraying.
● It is possible to manually purge the exhaust. This may be desirable, for
instance, before parking in a garage. This is done by pressing the H
2O
switch. ( P. 173)
● On cold days, water vapor in the exhaust may appear as a white mist emit-
ted from the tailpipe. This is not a malfunction.
● If the tailpipe is blocked, the fuel cell system will stop.
■ Hydrogen detectors
When the power switch is turned to ON mode, the hydrogen detectors are
activated.
