Fuel cell system
MIRAI_OM_USA_OM62025U
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.
This diagram is for illustrative purposes only and may differ f rom the
actual vehicle.

◆Using Eco drive mode
Using Eco drive mode (P. 181) 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. 2 5 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. 266).
● 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.

NOTICE
■To prevent damage to or incorr ect operation of the LDA system
Observe the following to ensure that the LDA system functions c orrectly.
● Do not modify the headlights or attach stickers to the surface of the lights.
● Do not modify the suspension.
If any suspension parts need to be replaced, contact your Toyota dealer.
● Do not install or place anything on the hood or the grille. Als o, do not install
a grille guard (bull bars, kangaroo bar, etc.).
● If your windshield needs repairs, contact your Toyota dealer.
■ Camera sensor
Observe the following to ensure that the LDA system functions c orrectly.
● Keep the windshield clean at all times.
Performance could be affected if the windshield is dirty, or if raindrops,
condensation or ice are adhering to the windshield.
● Do not spill liquid onto the camera sensor.
● Do not attach window tinting to the windshield.
● Do not install an antenna in front of the camera lens.
● If the windshield area in front of the camera sensor is fogged up, use the
windshield defogger to remove the fog from that area. ( P. 259)
When it is cold, using the heater with air blowing to the feet may allow the
upper part of the windshield to fog up. This will have a negative effect on
the images.
● Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield, be careful not to g et any glass
cleaner, etc., on the lens. Also, do not touch the lens.
For lens repair, contact your Toyota dealer.
● Do not change the installation position or direction of the cam era sensor or
remove it.
The direction of the camera sensor is precisely adjusted.
● Do not subject the camera sensor to strong impact or force, and do not
disassemble the camera sensor.
● If the windshield needs to be replaced, contact your Toyota dea ler.
●Do not attach a sticker or other items to
the windshield near the camera sensor.

Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor ( P. 264) detects fog on
the windshield and controls the air conditioning system to prev ent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to recirculated air mode. Thi s is effective in
preventing outside air from entering the vehicle interior. Duri ng cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ Operation of the air conditioni ng system in ECO HEAT/COOL mode
● In ECO HEAT/COOL mode, the air conditioning system is controlle d as fol-
lows to prioritize fuel efficiency:
• Fluid (heating) heater and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the temperature settings and fan speed
• Touch while in , and is set
• Touch while in , and ECO HEAT/COOL mode is canceled
■ Operation of the air conditioning system in Eco drive mode
When ECO MODE switch is pressed, operations switch over to ECO HEAT/
COOL mode. ( P. 183)
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pre ssing .

NOTICE
■Cleaning detergents
● Do not use the following types of detergent, as they may discol or the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasol ine,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol
● Do not use a polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
● Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended perio ds of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if wate r comes
into contact with electrical components such as the audio syste m above or
under the floor of the vehicle. Water may also cause the body to rust.
■ When cleaning the inside of the windshield
Be careful not to touch the camera sensor ( P. 216).
If the camera is accidentally scratched or hit, LDA system and Automatic
High Beam may not operate properly or may cause a malfunction.
■ Cleaning the inside of the rear window
● Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe the
window in strokes running parallel to the heater wires or antenna.
● Be careful not to scratch or damage the heater wires or antenna .
