The black line on the left rearview mirror of an Audi serves to identify distance and position. Significance of the black line: The inner side of the black line provides a normal field of view for observing nearby conditions. Due to its larger curvature, it allows for a clear view of nearby situations, such as seeing the position of the rear wheels and adjacent vehicles when reversing. The outer side of the black line expands the driver's field of vision. During regular use, the Audi's rearview mirror combines two different curvatures to balance both near and far views, effectively reducing blind spots and enhancing convenience, thereby lowering potential hazards. Design principle of the Audi left rearview mirror: The black dotted line acts as a divider, with the right side being a flat mirror and the left side a convex mirror. This design doubles the field of vision while maintaining minimal distortion and virtually eliminates blind spots during turns, enabling the driver to see a panoramic view behind the vehicle.

Is Windshield Repair Effective?

For minor windshield damage, repair is quite effective. Here are the relevant details: 1. Glass Repair Agent: The main component of automotive glass repair agent is photosensitive resin. After repairing the glass with this agent, the car glass can quickly restore its original strength and effectively perform its safety function. During the repair process, patience is required as the repair agent needs to be slowly infiltrated into the crack along the damage. The downside is that from certain reflective angles, traces of the repair may still be visible. 2. Glass Replacement: If the windshield is cracked or damaged, the cracks will gradually spread, becoming longer and expanding outward. Once they reach a certain length, the only option is to replace the glass. Therefore, it is important not to ignore windshield damage. The earlier the glass is repaired after damage occurs, the better the results will be. Otherwise, over time, foreign objects may enter the crack, affecting the final repair outcome.

How to Use the Auto Hold Function in a Car?
