Kia Forte: Windshield defrosting and defogging

WARNING - Windshield heating

Do not use the
or 
position during cooling operation in extremely humid weather to reduce the likelyhood of fog up.

• For maximum defrosting, set the temperature control to the extreme right/hot position and the fan speed control to the highest speed.
• 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, outside rear 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 battery has been discharged or disconnected, it resets to the defog logic status.

Auto defogging system (Only for automatic climate control system, if equipped)

Auto defogging reduces the probability of fogging up the inside of the windshield by automatically sensing the moisture inside the windshield.

The auto defogging system operates when the heater or air conditioning is on.

This indicator illuminates when the auto defogging system senses the moisture inside the windshield and operates.

If more moisture is in the vehicle, higher steps operate as follows. For example, if auto defogging does not defog inside the windshield at step 1 Outside air position, it tries to defog again at step 2 Blowing air toward the windshield.

Step 1 : Outside air position

Step 2 : Blowing air toward the windshield

Step 3 : Increasing air flow toward the windshield

Step 4 : Operating the air conditioning

Step 5 : Maximizing the air conditioning

If your vehicle is equipped with the auto defogging system, it is automatically activated when the conditions are met. However, if you would like to cancel the auto defogging system, press the front defroster button 4 times within 2 seconds while pressing the AUTO button. The indicator will blink 3 times to notify you that the system is cancelled. To use the auto defogging system again, follow the procedures mentioned above.

If the battery has been disconnected or discharged, it resets to the auto defogging status.

✽ NOTICE

• When the air conditioning is turned on by Auto defogging system, if you try to turn off the air conditioning, the indicator will blink 3 times and the air conditioning will not be turned off.
• For efficiency, do not select recirculated air position while Auto defogging system is operating.

CAUTION

Do not remove the sensor cover located on the upper end of the driver side windshield glass. Damage to the system parts could occur and may not be covered by your vehicle warranty.
