Note:

Heating

In HV mode, the gasoline engine may operate in order to extract heat from the engine coolant via the heater.

In EV mode, heating is done by a heat pump system.

When the outside temperature is low or it is snowing, compared to conventional vehicles, heating may be less effective and warm air may not come out.

When the outside heat exchanger is frosted over, fan speed declines and it may become harder to heat the interior.

However, it is not a malfunction. In this situation, the air temperature from the outlets may not change even though the set temperature is raised.

If frost has formed of the outside heat exchanger, the heating performance will decline. The frost can be removed from the outside heat exchanger by operating the Remote Air Conditioning System before driving (Remote Air Conditioning System). When frosted over, the heating operation of the Remote Air Conditioning System starts after defrosting.

When “ AUTO” switch is turned on, the heating is controlled optimally. Therefore, the set heating performance may not be achieved even if the fan speed setting is increased.

Outside heat exchanger

In the following situations the gasoline engine may operate in order to extract heat from the engine coolant via the heater even in EV mode.

The outside temperature is approximately 14°F (-10°C) or low

is operating

Water droplets during air conditioning operation

The outside heat exchanger, accumulator and air conditioning piping may incur condensation or frost may form.

During or after the air conditioning operation, water droplets may fall from the vehicle. However, it is not a malfunction.

Accumulator

Outside heat exchanger

Fogging up of the windows

The windows will easily fog up when the humidity in the vehicle is high. Turning “ A/C” switch on will dehumidify the air from the outlets and defog the windshield effectively.

If you turn “ A/C” switch off, the windows may fog up more easily.

The windows may fog up if the recirculated air mode is used.

While using “ My Room Mode”

It may not be possible to obtain the intended defogging performance even if is pressed. If the windows need to be defogged before driving, stop charging power and then press .

When the outside temperature is low, heating may feel insufficient due to restricted operation of the air conditioning.Heating cannot be performed when it is 14°F (-10°C) or less as the gasoline engine cannot be started during “ My Room Mode”. If heating is desired, stop charging and remove the AC charging cable from the vehicle.

When driving on dusty roads

Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the air intake mode be set to outside air mode and the fan speed to any setting except off.

Outside/recirculated air mode

Setting to the recirculated air mode temporarily is recommended in preventing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high.

Outside/recirculated air mode may automatically switch depending on the temperature setting or the inside temperature.

When the outside temperature exceeds 75°F (24°C) and the air conditioning system is on

In order to reduce the air conditioning power consumption, the air conditioning 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.

It is possible to switch to outside air mode at any time by pressing the outside/recirculated air mode switch.

Operation of the air conditioning system in Eco drive mode

In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel efficiency:

Engine speed 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:

Turn off Eco drive mode (Driving mode select switch)

Turn off Eco air conditioning mode

When the driving mode is set to Eco driving mode, the Eco air conditioning mode will be turned on automatically. Even in this case, the Eco air conditioning mode can be turned off by pressing the Eco air conditioning mode switch.

When the outside temperature falls to nearly 32°F (0°C)

The dehumidification function may not operate even when “ A/C” switch is pressed.

Ventilation and air conditioning odors

To let fresh air in, set the air conditioning system to the outside air mode.

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.

When parking, the system automatically switches to outside air mode to encourage better air circulation throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

Using the Intelligent Assistant (if equipped)

Air conditioning system can be operated using the Intelligent Assistant.

For details regarding the Intelligent Assistant, refer to the “ MULTIMEDIA OWNER’S MANUAL”.

Warning:

Cautions for using “ My Room Mode”

Do not leave children, people who need assistance, or pets inside the vehicle. The system may turn off automatically and the interior temperature may become high or low, resulting in heat stroke, dehydration or hypothermia. Failure to do so may result in death or serious injury.

To prevent the windshield from fogging up

Do not use the windshield defogger switch during cool air operation in extremely humid weather.The difference between the temperature of the outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your vision.

When the outside rear view mirror defoggers are operating

Do not touch the rear view mirror surfaces when the outside rear view mirror defoggers are on.

Notice:

To prevent 12-volt battery discharge

Do not leave the air conditioning system on longer than necessary when the hybrid system is off.

When repairing/replacing parts of the air conditioning system

Have repair/replacement performed by your Toyota dealer. When a part of the air conditioning system, such as the evaporator, is to be replaced, it must be replaced with a new one.
