Fuel cell system
MIRAI_OM_USA_OM62073U
The fuel cell vehicle has high-voltage components (about 650 V m axi-
mum) such as a fuel cell stack, traction battery, power control unit,
high-voltage cables (which are di stinguished from low-voltage cables
by their orange covers), electric motor (traction motor), etc., and high-
temperature parts such as the radiator for cooling. Pay attenti on to all
warning labels attached to the vehicle.

There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■If a warning light comes on, a warning message is displayed, or the
12-volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start procedure is
repeated, contact your Toyota dealer.
■ If “Hydrogen Leakage Detected Visit Your Dealer” is displayed on the
multi-information display
A small amount of hydrogen gas may be leaking. Have the vehicle inspected
immediately at the nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer” is displayed on the multi -informa-
tion display
● Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
P. 98
● The air conditioning system will shut off automatically.
■ Running out of fuel
When the vehicle has run out of fuel and the fuel cell system c annot be
started, refuel the vehicle until the low fuel level warning li ght (P. 420) turns
off before trying to restart. It may not be able to restart if the refueled amount
is too low (less than about 2.7 lb. [1.2 kg]).

◆Using Eco drive mode
Using Eco drive mode (P. 195) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode ( P. 3 0 8 ) .
◆Air conditioning system on/off
● Turn off the air conditioning system operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temperature is high, use the recircu -
lated air mode. This decreases the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize the need for cabin heating ( P. 316).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning syst em
turned on.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tires have mo re rolling friction and their use on
dry roads lead to poor fuel economy. Use tires that are appropr iate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel economy. Installing a large roof rack wil l also
reduce fuel economy.

The following modes can be selected to suit driving conditions.
■Eco drive mode/Power mode
Eco drive mode
Suitable for improving the
fuel economy, because the
torque corresponding to the
accelerator pedal depres-
sion amount can be gener-
ated more smoothly than it is
in normal conditions.
is displayed on the air conditioning screen and the system
goes into ECO HEAT/COOL mode. ( P. 308)

Regenerative Braking
When the shift position is in D, regenerative braking is engage d when the foot
is released from the accelerator pedal.
■ ECO HEAT/COOL mode operation for Eco drive mode
●When the “ECO MODE” switch is pressed, the system switches over to
ECO HEAT/COOL mode. ( P. 311) During the use of Eco drive mode, only
the ECO HEAT/COOL mode can be canceled.
● When it is desired to improve the effectiveness of the air cond itioning sys-
tem, perform the following operations.
• Adjust the temperature settings and airflow mode.
• Press of the air conditioning operation panel ( P. 306) and can-
cel the ECO HEAT/COOL mode, or cancel Eco drive mode.
■ Power mode automatic deactivation
Power mode is automatically deactivated if the power switch is turned off after
driving in power mode.
■ Shifting from P on a slope
When changing to another position from P when parked on a slope in the P
position, vibrations may be felt.
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in regenerative braking may cause the vehicle to spin or
skid, resulting in an accident.
■ For the shift lever
Do not remove the shift lever knob or use anything but a genuin e Toyota
shift lever knob. Also, do not hang anything on the shift lever .
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
■ P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for
example, directly before stopping the vehicle), the vehicle may stop sud-
denly when the shift position switches to P, which could lead t o an accident.

If a warning message is displayed on the multi-information disp lay
A system may be temporarily 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 become operational.
If the message does not disappear, contact your Toyota dealer.
SituationActions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterTo clean the part of the windshield in
front of the front camera, use the
windshield wipers or the windshield
defogger of the air conditioning sys-
tem ( P. 309)
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 of the front camera
is obstructed, such as when the hood
is open or a sticker is attached to the
part of the windshield in front of the
front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.

The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s detection areas before the display is shown and the bu zzer
sounds.
• Thin posts or objects lower than the sensor may not be detecte d when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ Muting the buzzer sound
●To mute the buzzer sound
The buzzer can be temporarily muted by pressing of the meter c ontrol
switches while an obstacle detection display is shown on the mu lti-informa-
tion display.
● To cancel the mute
Mute will be automatically canceled in the following situations .
• When the shift position is changed
• When the vehicle speed has reac hed or exceeded approximately 6 mph
(10 km/h)
• When the intuitive parking assist is turned off once and turned on again
• When the power switch is turned off once and turned to ON mode again
• When a sensor is malfunctioning
■ If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an obstacle may not be detected. If the sens or thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction Visit Your Dealer” is displayed on the
multi-information display
Depending on the malfunction of the sensor, the device may not be working
normally.
Have the vehicle inspected by your Toyota dealer.
