 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 types
 P.483
■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 com-
pletely fill hydrogen tanks.
●If the fueling cannot be completed
due to trouble with the station
equipment, call the number indi-
cated on the equipment.
Opening the fuel door
Fuel with compressed
hydrogen gas only at hydro-
gen stations.
Fuel at hydrogen stations
conforming with the Society
of Automotive Engineers
(SAE) J2601 fueling proto-
col or laws that may super-
sede such SAE protocols.
Refer to the Mirai Station

nected services,

800-331-4331 (for U.S.
owners) or 1-888-869-6828
(for Canadian owners).
 Observe any notices or
instructions shown at hydro-
gen stations.
The filling time and amount
of fuel may depend on out-
side temperature and the
equipment at that hydrogen
station.
Vehicles with expired hydro-
gen tanks must not be used.
Check P.81 to learn how
and when to check the expi-
ration. Consult your Toyota
dealer.
Before filling
WARNING
■When filling

WARNING
●Do not attach objects, such as
stickers, transparent stickers,
etc., to the oute r side of the
windshield in fr ont of the front
camera (shaded area in the
illustration).
From the top of the windshield
to approximately 0.4 in. (1 cm)
below the bottom of the front
camera
Approximately 7.9 in. (20 cm)
(Approximately 4.0 in. [10 cm]
to the right and left from the
center of the front camera)
●If the part of the windshield in
front of the front camera is
fogged up or covered with con-
densation or ice, use the wind-
shield defogger to remove the
fog, condensation or ice.
( P.326, 334)
●If water droplets cannot be
properly removed from the area
of the windshield in front of the
front camera by the windshield
wipers, replace the wiper insert
or wiper blade.
●Do not attach win dow tint to the
windshield.
●Replace the windshield if it is
damaged or cracked.
After replacing the windshield,
the front camera must be recali-
brated. Contact your Toyota
dealer for details.
●Do not allow liquids to contact
the front camera.
●Do not allow bright lights to
shine into the front camera.
●Do not dirty or damage the front
camera.
When cleaning the inside of the
windshield, do not allow glass
cleaner to contact the lens of
the front camera. Also, do not
touch the lens.
If the lens is dirty or damaged,
contact your Toyota dealer.
●Do not subject the front camera
to a strong impact.
●Do not change the installation
position or direction of the front
camera or remove it.
●Do not disassemble the front
camera.
●Do not modify any components
of the vehicle around the front
camera (inside rear view mirror,

■If a warning message is displayed on the multi-information display
A system may be tempor arily unavailable or there may be a malfu nction in
the system.
●In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will be come operational.
If the message does not disapp ear, contact your Toyota dealer.
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappea r, contact your Toyota dealer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter ( P.326, 334).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc., to clear the obstruction.
When “Pre-Collisio n System Radar
In Self Calibration Unavailable See
Owner’s Manual” is displayed.Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, th e radar may
judge the surrounding environment can not be properly recognize d. In that
case, “Pre-Collision System Unavailable See Owner’s Manual” is dis-
played.

●Emergency steering assist
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.
If any of the following occur wh ile the emergency steering assi st function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is tur ned sharply or abruptly.
• The brake pedal is depressed.
●Intersection right/left turn assistance (pre-collision warning)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
●Intersection right/left turn assistance (pre-collision braking)
When the turn signal lights are not flashing, support for turning left or right at
an intersection which targets on coming vehicles does not work.
■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur- rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. (

information display.
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the driver
if the vehicle may deviate from
the current lane or course
*, and
also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the dynamic
radar cruise control with full-
speed range is operating, this
system will operate the steering
wheel to maintain the vehicle’s
lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front camera.
Additionally, it detects preceding
vehicles using the front camera
and radar.
