HYDROGEN FUEL CELL
SYSTEM & SAFETY FEATURES
Fuel cell vehicles efficiently use electricity, which is generated by a \
chemical
reaction between hydrogen and oxygen in a fuel cell stack. Excess electr\
icity is
stored in a traction battery that is used to power high voltage systems \
and assist on
initial acceleration.
The fuel is H
2 (compressed hydrogen gas), so the exhaust, when running, is
only water and water vapor. As they do not emit CO
2 (Carbon Dioxide) and NOx
(Nitrogen Oxides) at the tailpipe, fuel cell vehicles are considered zero emission
vehicles.
NOTE: Fuel consumption and energy information of the Hydrogen Fuel Cell
System are shown on the Multi-Information Display.
Fill with fuel at hydrogen stations compliant with SAE J2601.
If you have questions about hydrogen station compliance, consult your Authorized
Mirai Fuel Cell Toyota Dealer.
Observe the notices and cautions shown at the hydrogen station.
The filling time and amount may differ depending on the equipment of the\
hydrogen
station. It may make the possible driving distance shorter. - Ensure tire pressures are maintained at levels specified in the Owner’\
s Manual.
- Drive vehicle smoothly. Avoid abrupt acceleration and deceleration.
- Avoid driving at speeds that are higher than necessary, especially on \
the highway.
- When possible, avoid sudden stops to maximize regenerative braking energy.
- Minimize use of the air conditioning.
When you arrive at the station, prepare for fueling:
1) Ensure the vehicle is OFF and in Park with parking brake set.
2) Press the fuel door release button and refer to instructions in ‘Fuel door release button & cap section’ to prepare the vehicle to accept hydrogen fuel.\
Note: Fuel door will not open if the READY indicator is on. The fuel door will
automatically re-lock if you don’t open within 30 seconds.
3) Now you are ready to refuel. Outside the vehicle at the pump, use the station’s best practice guidelines and instructions on how to refuel using their nozzle.
For assistance, call Customer Support toll free at 1-800-331-4331 (option 8.)

*The integrated hand grip locks and
unlocks the nozzle, creating a secure
connection for safe fueling.
Once the nozzle is secure, you can follow the station’s
instructions to begin dispensing fuel.
CAUTION: Ensure that the nozzle lock is properly engaged to
the vehicle. Failure to do this may result in the nozzle coming
off when the flow of hydrogen begins. This may result in
damage to the nozzle, station, vehicle, your own person or
people near the fueling station.
Seat the nozzle onto the receptacle fully.
(This is the first step to help create a secure connection for
safe fueling.)(1)
After fueling is complete, pull the latch to unlock the hand grip
and remove the nozzle.(4)
To lock the nozzle, squeeze the hand grip until the latch is
engaged.(2)
Gently pull back on the nozzle to ensure it is locked onto the
receptacle. (Be careful to not squeeze or contact the hand grip
when checking if the nozzle is secure, as it may unlock the
nozzle.)(3)
H70 allows for a full fill-up on the Toyota Mirai, and is the preferred \
fueling method.

Holding the handle, gently pull back on the collar
to ensure the nozzle is securely locked. Once
the nozzle is secure, you can follow the station’s
instructions to begin dispensing fuel.
Make sure the lock is in the OFF position.

NOTE: If the nozzle cannot be removed after fueling, it may be frozen to the
vehicle. Wait for the hydrogen nozzle to thaw before attempting to remove. Do
not pull or rotate the hydrogen nozzle forcibly or damage will occur.
Refer to the Refueling section in the Owner’s Manual for additional i\
nformation.
After filling is complete, rotate the lock
back to the OFF position.(5)(6)

Water is a natural by-product of the fuel cell process. The system is de\
signed to
automatically purge water from the drain pipe at the rear of the vehicle\
while driving
and sometimes while it is shut off.
Water can be manually purged before parking in certain situations by pre\
ssing
the “H
20” switch with the vehicle in “READY” mode. The system will regulate water
levels automatically. Drivers should typically let the vehicle handle th\
is as opposed
to using this switch.
Refer to the Owner‘s Manual for more details on this system before at\
tempting to
use it.
