Regenerative Braking
When the shift position is in D, regenerative braking is engaged 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. 263) 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 conditioning sys-
tem, perform the following operations.
• Adjust the temperature settings and airflow mode.
• Press of the air conditioning operation panel ( →P. 258) 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 genuine 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 to an accident.

1965-3. Operating the lights and wipers
MIRAI_OM_USA_OM62023U
Washer/wiper dual operation
Wipers will automatically operate a
couple of times after the washer
squirts.
■The windshield wipers and washers can be operated when
The power switch is in ON mode.
■ Effects of vehicle speed on wiper operation
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor
●If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that “AUTO” mode is acti-
vated.
● If the temperature of the raindrop sensor is 194 °F (90 °C) or higher, or 5 °F
(-15 °C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO” mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the
windshield washer fluid reservoir.
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc.,
are present on the windshield.
WARNING
■ Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers, etc., do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.

Interior features
MIRAI_OM_USA_OM62023U■
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. 266) detects fog on
the windshield and controls the air conditioning system to prevent 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. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending 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 controlled 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 conditio ning system in Eco drive mode
When ECO MODE switch is pressed, oper ations switch over to ECO HEAT/
COOL mode. ( →P. 183)
■ When the outside temperature exceeds 75°F (24°C) and the air condition-
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 pressing .

When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
■ Air conditioning filter

■ Changing the response of the switch for the air conditioning operation
panel
The reaction time, from when the switch is touched, can be changed by the
following operations.
The air conditioning cannot be operated during following operation.
Touch (decrease) and for about 3 seconds.
“01” ~ “05” is displayed in the monitor of the passenger side tempera-
ture.
Each time is touched, the reaction time switches over as follows.
01 (about 0.06 sec.) → 02 (about 0.08 sec.) → 03 (about 0.10 sec.) →
04 (about 0.12 sec.) → 05 (about 0.14 sec.)
With the desired setting displayed, without switching over the screen by
performing touch operations for about 5 seconds, when the power
switch is turned off the configuration is complete.
