What are the steps to defog the Nissan Teana?

[LeRobert]

You can open a small gap in the windows on both sides to allow air convection inside the car, gradually bringing the interior temperature closer to the outside temperature. Using the air conditioning defogging function is a common practice. Adjust the fan speed appropriately and turn on the cooling switch, so that cold air will blow onto the glass. This type of defogging spray can be applied to the car's windshield or wiped onto the glass with a towel. Generally, one application of defogging spray can last for about half a month. Small water droplets formed can be wiped off directly with a towel to remove the fog, but it's best to stop the car and ensure safety before wiping off the fog, as doing so while driving can affect safety.
