Toyota RAV4 (XA40) 2013-2018 Service Manual: System description
- General
- The air conditioning system has the following features:
- In accordance with the temperature set using the
temperature control switch, the air conditioning
amplifier determines the outlet temperature
based on the input signals from various sensors.
In addition, corrections are made in accordance with the signals from the water temperature sensor to control the outlet air temperature.
- Controls the blower motor in accordance with the airflow volume determined by the air conditioning amplifier based on the input signals from various sensors.
- Automatically changes the outlets in accordance with the outlet mode ratio that is determined by the air conditioning amplifier based on the input signals from various sensors.
- Based on the signals from the ambient temperature sensor, this system calculates the outside temperature and indicates it in the multiinformation display in the combination meter assembly.
- The left/right independent temperature control and neural network control make air conditioner control available to suit the persons in the driver seat and in the passenger seat.
- Turns the rear defogger and outside rear mirror heaters on for 15 minutes when the rear defogger switch is pressed. Turns them off if the switch is pressed while they are operating.
