8-8 Climate Controls For vehicles with heated outside mirrors, the surface of the outside mirrors will also heat when the rear window defogger is activated. See Heated Mirrors on page 2‑14. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Remote Start Climate Control Operation For vehicles with remote start, when it is activated the climate control system heats and cools the inside of the vehicle using the previous system settings before the vehicle was turned off. The climate control knobs will remain active during a remote start. However, the climate control buttons will be inactive until the ignition is turned on by the key. If the fan is off, the climate control system will not operate during remote start. With the automatic climate control system, the climate control displays "RS" in place of the temperature to indicate that remote start is activated. For best performance, turn both the fan and mode knobs to AUTO. If the temperature is cold enough and the mode knob is set to AUTO, the system begins in defrost to clear the windows. See Remote Keyless Entry (RKE) System Operation on page 2‑3. When the weather is cool or damp, operating the system in recirculation for extended periods of time can cause fogging of the vehicle's windows. To clear the fog, select either defog or defrost. Make sure the air conditioning is on. Allow the air conditioning to run automatically to help dehumidify the air. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear): Press to turn the rear window defogger on or off. An indicator light comes on to show that the rear window defogger is on. If driving below 80 km/h (50 mph), the rear window defogger turns off about 15 minutes after the button is pressed. If additional warming time is needed, press the button again. If the vehicle's speed is maintained above 80 km/h (50 mph), the rear window defogger remains on once the button is pressed.
