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.

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

WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be d riven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyot a dealer.
● The intuitive parking assist operation display flashes, and a buzzer sounds
when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.

Parking Suppor t Brake fu nction (for static
objects)

The system operates in the following situations when a stationa ry
obstacle is detected in the trav eling direction of the vehicle.
◆The vehicle is driven at low speeds and the brake pedal is not
depressed, or is depressed too late
◆The accelerator pedal is depressed too far
: If equipped
When a collision may occur with an obstacle while parking or
traveling at low speeds, when the vehicle suddenly moves for-
ward due to mistaken accelerator pedal operation, or when the
vehicle moves due to the wrong shift position being selected,
the sensors detect obstacles to the front or rear in the travel ing
direction of the vehicle, and the system operates to lessen
impact with obstacles such as walls, and reduce resulting dam-
age.
Examples of system operation

2765-5. Using the driving support systems

(for static objects) is suspended,
system operations do not resume
until the function is switched ON
(enable) through the settings
screen on the multi-information dis-
play. (System operation does not
resume by operating the power
switch.)
When the Parking Support Brake function (for static objects) de tects
an static obstacle with a probab ility of collision, the fuel cell system
output is restricted to restrain an increase in vehicle speed. (fuel cell
