Sensors
The solar sensor located on the instrument panel, near the windshield, monitors the solar heat.
The interior temperature sensor, located on the instrument panel to the right of the steering wheel, measures the temperature of the air inside the vehicle.
The climate control system uses the information from these sensors to adjust the fan speed and the air delivery, in order to maintain the selected temperature. The system may also supply cooler air to the side of the vehicle facing the sun.
The recirculation mode will also be activated, as necessary.
Do not cover the sensors or the automatic climate control system will not work properly.
