The automatic anti-fog system reduces the possibility of fogging on the inside of the windshield by automatically detecting the humidity inside the windshield.

The automatic anti-fog system operates when the heater or air conditioner is on.

Information

The automatic defogging system may not operate normally if the outside air temperature is below 14 °F (-10 °C).

When the automatic anti-fog system is operating, the indicator illuminates.

If increased humidity is detected in the vehicle, the automatic anti-fog system will operate in the following sequence:

Step 1) The air conditioner button turns on.
Step 2) The air intake control switches to fresh air mode.
Step 3) The mode will be changed to defrost to direct airflow to the windshield.
Step 4) The fan speed will be set to MAX.

If the air conditioner is turned off or the recirculation position is selected manually while the automatic defogging system is on, the automatic defogging system indicator will flash 3 times to signal that manual control has been canceled.

To cancel or reset the automatic anti-fog system

Press the windshield heater button for 3 seconds with the ignition key in the ON position.

When the automatic anti-fog system is turned off, the ADS OFF symbol flashes 3 times and ADS OFF is displayed on the climate control information screen.

When the automatic anti-fog system is reset, the ADS OFF symbol will flash 6 times without a signal.

Information

  • When the air conditioner is turned on by the automatic anti-fog system, if you try to turn off the air conditioner, the indicator flashes 3 times and the air conditioner does not turn off.
  • For better efficiency, do not select recirculation mode while the automatic defogging system is operating.
  • When the automatic anti-fog mode is selected, the fan speed, temperature and air intake mode set manually are cancelled for the best defogging result.
