Windshield Defrosting And Defogging

Windshield heating

Do not use the or position during cooling operation in extremely humid weather. The difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up, causing loss of visibility could cause an accident resulting in serious injury or death. In this case, set the mode selection knob or button to the position and fan speed control knob or button to a lower speed.

  • For maximum defrost performance, set the temperature control knob to the highest temperature setting (rotated all the way to the right) and the fan speed control to the highest setting.

  • If warm air to the floor is desired while defrosting or defogging, set the mode to the floor-defrost position.

  • Before driving, clear all snow and ice from the windshield, rear window, side view mirrors, and all side windows.

  • Clear all snow and ice from the hood and air inlet in the cowl grill to improve heater and defroster efficiency and to reduce the probability of fogging up the inside of the windshield.

If the engine temperature is still cold after starting, then a brief engine warm up period may be required for the vented air flow to become warm or hot.

Defogging logic

To reduce the probability of fogging up the inside of the windshield, the air intake or air conditioning are controlled automatically according to certain conditions such as or positions. To cancel or reset the defogging logic, do the following.

Manual climate control system

  1. Turn the ignition switch to the ON position.

  2. Press the defroster button ().

  3. Press the air intake control button at least 5 times within 3 seconds.

The indicator on the air intake button will blink 3 times to indicate that the defogging logic has been disabled.

Repeat the steps again to re-enable the defogging logic.

If the battery has been discharged or disconnected, it resets to the defog logic status.

Automatic climate control system

  1. Turn the ignition switch to the ON position.

  2. Press the defroster button ().

  3. While pressing the air conditioning button (A/C), press the air intake control button at least 5 times within 3 seconds.

The Automatic Climate Control information screen will blink 3 times to indicate that the defogging logic has been dis-abled.

Repeat the steps again to re-enable the defogging logic.

If the battery has been discharged or disconnected, it resets to the defog logic status.

When the Auto Defogging System operates, the indicator will illuminate.

If a high amount of humidity is detected in the vehicle, the Auto Defogging System will be enabled. The following steps will be performed automatically:

Step 1) The A/C button will turn ON and the air intake or icon control will change to Fresh mode.

Step 2) The mode will be changed to defrost to direct airflow to the windshield.

Step 3) The fan speed will be rising up to level 3.
