Climate Controls are shorter and less frequent. To turn Auto Defog off or on, see "Climate and Air Quality" under Vehicle Personalization on page 5‑34. 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 the radio's ability to pick up stations clearly. The repairs would not be covered by the vehicle warranty. Remote Start Climate Control Operation (If Equipped): For vehicles with the remote start feature, the climate control system may run when the vehicle is started remotely. The system uses the driver 's previous settings to heat or cool the inside of the vehicle. The rear defog may come on during remote start based on cold ambient conditions. If the vehicle has heated seats, they may come on during a remote start. The heated seat indicator lights do not come on during a remote start. See Remote Vehicle Start on page 2‑8 and Heated Front Seats on page 3‑6. 8-5 Sensors The solar sensor 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 dual automatic climate control system may not work properly. Rear Window Defogger = (Rear Window Defogger): Press to turn the rear window defogger on or off. The rear window defogger turns off automatically after about 10 minutes. If turned on again, it runs for about five minutes before turning off. At higher speeds, the rear window defogger may stay on continuously. For vehicles with heated outside rearview mirrors, they turn on with the rear window defogger and help to clear fog or frost from the surface of the mirror. See Heated Mirrors on page 2‑16.
