Opening the fuel door
●Close the all the doors and windows.
● Set the parking brake.
● Shift the shift position to P.
● Turn the power switch off.
● Turn off the headlights.
■Fuel Type
Compressed hydrogen gas
■ Notes on fueling
●Fueling will not be possible if the pressure inside the vehicle ’s hydrogen tanks
is higher than the supply pressure of the hydrogen station. If the hydrogen
tanks are more than half full, the vehicle will be unable to fu el at a H35 dis-
penser.
A hydrogen station with a H70 dispenser (supply pressure of 101 50 psi
[70 MPa, 714 kgf/cm
2, 700 bar] is necessary to completely fill hydrogen tanks.
● If the fueling cannot be completed due to trouble with the station equipment,
call the number indicated on the equipment.
● Fuel with compressed hydrogen g as only at hydrogen stations.
● Fuel at hydrogen stations confor ming with the Society of Automo-
tive Engineers (SAE) J2601 fueling protocol or laws that may
supersede such SAE protocols.
● Refer to the Mirai Station Finder Application in Connected ser-
vices, https://www.toyota.com/connected-services
(for U.S. own-
ers) or https://www.toyota.ca/connected
(for Canadian owners), or
call 1-800-331-4331 (for U.S. owners) or 1-888-869-6828 (for
Canadian owners).
● Observe any notic es or instructions show n at hydrogen stations.
● The filling time and amount of fuel may depend on outside tem-
perature and the equipment at that hydrogen station.
● Vehicles with expired hydrogen tanks must not be used. ( P. 94)
Consult your Toyota dealer.

WARNING
■When filling
Observe the following precautions while fueling the vehicle.
Failure to do so may result in death or serious injury.
● Turn the power switch off before fueling.
● Ensure the hydrogen gas nozzle is locked onto the vehicle recep tacle
before filling. This can be done by pulling on the hydrogen gas nozzle to
check that it cannot be pulled off.
Failure to do so may result in injury or damage to the hydrogen gas nozzle
or vehicle.
● Do not smoke while fueling.
● Because the fuel is cold, the hydrogen gas nozzle and vehicle r eceptacle
surface will become cold, and frost may develop. After fueling is com-
pleted, remove the hydrogen gas nozzle by the plastic handle on ly. Do not
touch any other parts of the hydrogen gas nozzle or vehicle rec eptacle
with bare hands immediately after fueling, as frostbite may occ ur.
NOTICE
■When filling
● Fuel only with compressed hydrogen gas at stations compliant with the
Society of Automotive Engineers (SAE) J2601 fueling protocol or laws that
may supersede such SAE protocols.
If improper fuels are used, the fuel cell stack will be damaged .
● Do not swing or drop the hydrogen gas nozzle, or subject it to a large
amount of force. Doing so may cause damage.
● If the hydrogen gas nozzle cannot be removed after fueling, it may be fro-
zen to the vehicle receptacle. Wait for the hydrogen gas nozzle to thaw
before attempting to remove. Do not pull or rotate the hydrogen gas nozzle
forcibly. Failure to follow these precautions may cause damage.
● Be sure to replace the cap after filling. If foreign material g ets in the vehicle
receptacle, it may cause damage.
● Do not put anything sharp, such as a screwdriver, blade, or any foreign
object into the mouth of the vehicle receptacle. If the vehicle receptacle is
damaged, hydrogen gas may leak during fueling.
● If you notice anything unusual about the vehicle receptacle, pl ease notify
your Toyota dealer.
● If you notice anything unusual with the hydrogen dispenser or h ydrogen
gas nozzle, please notify the hydrogen station operator. Contac t informa-
tion is usually displayed on the dispenser.
