Fuel cell vehicles use electricity, which is generated by a chemical rea\
ction 
between hydrogen and oxygen in a fuel cell stack. Excess electricity 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 and the multimedia 
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 the tire pressures are maintained at levels specified in the Owne\
r’s Manual.
- Drive the 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 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 th\
e station’s  best practice guidelines and instructions on how to refuel using their n\
ozzle.
