1785-1. Before driving
MIRAI_OM_USA_OM62073U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do not leave a door or window open if the curved glass is coate d with a
metallized film such as a silver-colored one. Reflected sunligh t may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the fuel
cell system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift position in P but the p arking brake is
not set, the vehicle may start to move, possibly leading to an accident.
■ When taking a nap in the vehicle
Always turn the fuel cell system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, causing the vehic le to uninten-
tionally move, which can lead to an accident, resulting in deat h or serious
injury.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In t his case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
NOTICE
■ When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may restrain the fuel cell system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift position to P . Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

With the headlights on, push
the lever away from you to turn
on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams with the headlights on or off.
■Daytime running light system
●The daytime running lights illuminate using the same lights as the parking
lights and illuminate brighter than the parking lights.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The fuel cell system is operating
• The parking brake is released
• The headlight switch is in the (Canada only), or
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
Turning on the high beam headlights
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

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.

MIRAI_OM_USA_OM62073U■
Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna .
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are insta lled.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is i nstalled.
• People may not be detected if they are wearing certain types o f clothing.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting i t. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle
