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 z\
ero 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 Au\
thorized
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 ene\
rgy.
- Minimize use of the air conditioning.
When you arrive at the station, prepare for fueling:
1) Ensure 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 and cap section’ to prepare the vehicle to accept hydrogen fue\
l.
Note: Fuel door will not release the lock if power switch is ON or if 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 th\
e station’s best practice guidelines and instructions on how to refuel using their n\
ozzle.

* The engine brake is the equivalent of downshifting. Shift to “Br”\
when strong
regenerative braking is desired (i.e. downhill driving, coasting to a s\
top, etc.).

Engine brake*
Use when a higher level of response is desired, such as when driving in \
mountainous regions or overtaking.
