Power restriction indicator
Blue: The fuel cell system output power is restricted, because the
coolant temperature is low.
Amber: The fuel cell system output power is restricted, because the
coolant temperature is high.
Outside temperature
Displays the outside temperature within the range of -40°F (-40°C)
to 122°F (50°C).
Low outside temperature indicator flashes when the ambient tem-
perature is 37°F (3°C) or lower.
Driving range distance
Displays the estimated maximum distance that can be driven with
the quantity of fuel remaining. • This distance is computed base d on your average fuel consump-
tion. As a result, the actual dist ance that can be driven may differ
from that displayed.
• When only a small amount of fuel is added to the hydrogen tanks, the display may not be updated.
Speedometer

heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

1985-4. Refueling
MIRAI_OM_USA_OM62023U
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 fuel at a H35 dis-
penser.
A hydrogen station with a H70 dispenser (supply pressure of 10150 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 ga s 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 Entune,
www.toyota.com
, or call 800-331-4331.
● Observe any notices or instructio ns shown 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 hydro gen tanks must not be used. (→P. 86)
Consult your Toyota dealer.

Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
“MAX”
“MIN”
■Adding fluid
Make sure to check the fluid type and prepare the necessary item.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
Brake fluid
Fluid typeFMVSS No.116 DOT 3 or SAE J1703 brake fluid
ItemClean funnel
WARNING
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.
