Fuel cell system
MIRAI_OM_USA_OM62025U
◆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
■Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 381)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:
● Fuel cell system stalling
● Short in electrical components
● Fuel cell system damage caused by water immersion
In the event that you drive on a flooded road and the vehicle i s flooded, be
sure to have your Toyota dealer check the following:
● Fuel cell system
● Brake function
● Changes in quantity and quality of transmission fluid, etc.
● Lubricant condition for the bearings and suspension joints (whe re possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. Wh en the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transp ort the vehi-
cle with both front wheels or all four wheels lifted.
■ If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the
12-volt battery in this situation.

In the situations below, the system may not be able to correctl y detect the
surrounding brightness levels, and may flash or expose nearby p edestrians
to the high beam. Therefore, you should consider turning the hi gh beams on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms, etc.).
• The windshield is obscured by fog, mist, ice, dirt, etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights , tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, d irty, are
changing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks, etc.).
• When frequently and repeatedly taking curves or driving on a w inding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly reflective, such as a co ntainer on a
truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed, etc.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.
WARNING
■ Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, ta king care to
observe your surroundings and turning high beam on or off manua lly if nec-
essary.

Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize
lane markers causing the lane departure warning function to ope rate incor-
rectly. However, this does not indicate a malfunction.
● When there are shadows on the road running parallel with lane m arkers, or
if a shadow covers the lane markers
● When driving through an area with no lane markers, such as a to ll booth, a
crossing or before a ticket checkpoint
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
● When lane markers are obscured or partially obscured by sand, dirt, etc.
● When driving on a road surface that is wet due to rain, previou s rainfall,
standing water, etc.
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are on a curb, etc.
● When driving on a particularly bright road surface, such as con crete
● When driving on a road surface that is bright due to reflected light
● When driving in a location where the light level changes rapidl y, such as the
entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shinin g directly
into the camera lens
● When driving on roads that are branching or merging
● When driving on winding roads or roads that are uneven
● When driving on rough or unpaved roads
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a h eavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicl e ahead is
extremely short
● When the vehicle experiences strong up-and-down motion such as when
driving on an extremely rough road or on a seam in the pavement
● When headlight brightness at nighttime is reduced due to dirt on the lenses,
or when the headlights are misaligned
■ When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if di fferent tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.
