MIRAI_OM_USA_OM62025U●
The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.

When the window cannot be opened or closed
When the jam protection function or catch protection function o perates
unusually and the door window cannot be opened or closed, perfo rm the fol-
lowing operations with the power window switch of that door.
● Stop the vehicle. With the power switch in ON mode, within 4 se conds of the
jam protection function or catch protection function activating , continuously
operate the power window switch in the one-touch closing direct ion or one-

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creepi ng.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the b rake
pedal will result in sudden acceleration that may lead to an ac cident.
• When backing up, you may twist your body around, leading to di fficulty
in operating the pedals. Make sure to operate the pedals proper ly.
• Make sure to keep a correct driving posture even when moving t he
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the fuel cell sys-
tem is on. As there are no engine sounds, pedestrians may misju dge the
vehicle’s movement.
● During normal driving, do not turn off the fuel cell system. Tu rning the fuel
cell system off while driving will not cause loss of steering o r braking con-
trol, however, power assist to the steering will be lost. This will make it
more difficult to steer smoothly, so you should pull over and stop the vehi-
cle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 361
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

MIRAI_OM_USA_OM62025U
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.

Starting the fuel cell syst em in cold temperatures
● When the power switch is pressed and the fuel cell system start s (P. 172)
during cold temperatures, the fuel cell stack is quickly warmed up using the
waste heat during power generation.
● When the temperatures is cold, it may take some time until the “READY”
indicator turns on.
● When starting the fuel cell system during cold weather, “FC Sys tem Shut-
down due to Freezing conditions Stop Your Vehicle in a Safe Place and
Contact Your Dealer” may be displayed in the multi-information display.
The fuel cell system is frozen and can not be started. Contact a Toyota
dealer.
● The power output will be temporarily limited until the fuel cel l system
reaches full operating temperature.
● The fuel cell system noises may become louder when the temperat ure is
cold. This is the normal warm-up operation and is not a malfunc tion. In
some cases, operation noises may continue for a some time even after the
“READY” indicator has turned on. ( P. 80)
■ Stopping the fuel cell syst em in cold temperatures
● When the power switch is pressed and the fuel cell system is stopped
( P. 173) during cold temperatures, the time for water purge from the tail-
pipe may be longer than usual to prevent liquid in the fuel cel l stack from
freezing.
● The water purge time may also be long if the system is stopped before fuel
cell system warm-up is completed.
● It is normal to hear hissing and other sounds during purge. ( P. 80)
● The H
2O indicator on the meter will illuminate during purge.
●
In extremely cold temperatures, the
“READY” indicator may take more than
10 seconds to illuminate. In this case,
the status progression of the fuel cell
system startup is displayed on the multi-
information display.

1765-2. Driving procedures
MIRAI_OM_USA_OM62025U■
Parking the vehicle during cold weather
●Water may automatically purge from the tailpipe, even when the fuel cell
system is off, in order to prevent liquid in the fuel cell stac k, hydrogen pipe-
lines, etc., from freezing.
● It is normal to hear hissing and other sounds during purge. ( P. 80)
● The H
2O indicator on the meter will illuminate during purge.
■ Water release function during cold weather
In the following cases, the fuel cell system automatic drainage may not oper-
ate. It may not be possible to start the fuel cell system due t o the fuel cell
stack, hydrogen pipes, etc, being frozen.
• When transporting or towing the vehicle in frozen areas
• When the 12-volt battery terminals are disconnected and remain as such
in frozen areas
Operate the water release function with the following procedure beforehand
to prevent water from freezing in the system.
Turn the power switch to ON mode and press the H
2O switch.
Check that the H
2O indicator on the meter turns on.
While depressing the brake, press the power switch to start the fuel cell
system.
Check that the “READY” indicator turns on.
Press the power switch to stop the fuel cell system.
The water release is automatically performed. During water purg e, the
H
2O indicator turns on. (Longer than normal water purge)
