Where is the defogging button in Vios?

[Una]

The Vios has two defogging buttons, one for the front windshield and one for the rear windshield. The front windshield defogging button features a fan-shaped icon with three upward wavy lines. When activated, the air conditioning will direct airflow to the front windshield, effectively removing fog and frost. The rear windshield defogging button has a square icon with three upward wavy lines, and when turned on, it heats up to eliminate fog and moisture on the rear glass. Tips for defogging your car: 1. Open the windows slightly on both sides of the vehicle. 2. Turn on the car's air conditioning. 3. Choose a car model with built-in defogging functionality. 4. Keep a defogging spray handy and apply it to the car windows. 5. Use dish soap with a dry cloth to wipe the windows. About defogging sprays: Defogging sprays are specialized anti-fog products designed to address such condensation issues. After application, the car glass becomes cleaner, clearer, and more transparent. A single application of defogging spray can last approximately 5-10 days.
