_ (Heated Windshield Washer, If Equipped): For more information, see Windshield Washer on page 3-11. Remote Start Climate Control Operation: For vehicles with remote vehicle start feature and it is activated, the climate control system heats and cools the inside of the vehicle using the previous settings of the system before the vehicle was turned off. See Remote Vehicle Start on page 2-15. 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 windshield defroster and/or rear window defogger turn on if it is cold outside. If the vehicle has heated seats, they turn on if the temperature inside the vehicle is cooler than 54°F (12.5°C) or if the outside temperature is cooler than 48°F (9°C). Sensors The solar sensor located on the instrument panel, near the windshield, monitors the solar heat. 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. 3-28
