How do you operate front windscreen demisters?

To operate front windscreen demisters, locate the climate control settings in your vehicle. Turn on the ignition, then set the air conditioning system to the defrost or windscreen setting, usually indicated by a symbol of a windscreen with arrows pointing upwards. Adjust the temperature and fan speed as needed to direct warm air onto the windscreen, helping to clear fog or ice. Ensure the recirculation mode is off for better airflow and faster defogging.
