Climate Controls The rear window defogger can be set to automatic operation; see "Climate and Air Quality" under Vehicle Personalization on page 5‑30. When auto rear defog is selected, the rear window defogger turns on automatically when the interior temperature is cold and the outside temperature is about 4°C (40°F) and below. The auto rear defogger turns off automatically after about 10 minutes. At higher speeds, the rear window defogger may stay on continuously. For vehicles with heated outside rearview mirrors, they turn on when the rear window defogger button is on and help to clear fog or frost from the surface of the mirrors. See Heated Mirrors on page 2‑17. Notice: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect your radio's ability to pick up stations clearly. The repairs would not be covered by your warranty. 8-5 The system will default to a heating or cooling mode depending on the outside temperature and then go back to the previous settings. See Remote Vehicle Start on page 2‑8. The rear window defogger turns on if it is cold outside. Sensors The solar sensor, located on top of the instrument panel near the windshield, monitors the solar heat. The climate control system uses the sensor information to adjust the temperature, fan speed, recirculation, and air delivery mode for best comfort. If the sensor is covered, the automatic climate control system may not work properly. M or L (Heated Seats, If Equipped): Press to turn the heated seats on or off. See Heated Front Seats on page 3‑7.
