[AdalynnMarie]

To identify the production date of car windows, look for a code located at the bottom left or right corner of the window glass. The last or second-to-last row of this code contains a number and small black dots, which indicate the production date of the glass. The number represents the production year of the window glass. The functions of car windows include: 1. Providing shelter from wind and rain, and reducing noise; 2. Minimizing wind resistance and improving aerodynamics; 3. Protecting the safety of passengers; 4. Lowering the interior temperature. Maintenance methods for car windows include: 1. Using appropriate windshield washer fluid according to the season; 2. Applying heat-insulating film to the car windows. Cleaning methods for car windows are: 1. Starting from the top of the vehicle, pour water and use a sponge to wipe away dirt; 2. Evenly spray glass cleaner solution onto the glass using a high-pressure spray bottle; 3. Dry the glass with a soft cloth.
