Q7 Sunroof Squeaking Solution: Check the fixing screws and apply specialized lubricant. The functions of a car sunroof are as follows: 1. Changing the traditional ventilation method. The car sunroof alters the conventional form of ventilation, allowing wind to flow in and create an air current that draws out the stale air inside the cabin. When the car is driving at high speed, air flows rapidly around the vehicle. Opening the sunroof creates a negative pressure area outside the car, and the difference in air pressure inside and outside the vehicle helps to extract the polluted air inside, achieving the purpose of ventilation and keeping the cabin air fresh. 2. Quickly removing interior fog. Using the sunroof for defogging is a fast and effective method. Especially during summer and autumn, when there is more rain and higher humidity. Drivers only need to open the sunroof to the rear-tilt ventilation position to easily eliminate fog on the front windshield, ensuring driving safety. 3. Rapid cooling and energy saving. Using the sunroof also has energy-saving benefits. On hot summer days, a car parked in the sun for an hour can easily reach an interior temperature of around 70℃. Simply opening the sunroof and utilizing the negative pressure formed on the roof while driving can quickly exchange and cool the hot air. This method is 2-3 times faster than using the car's air conditioning for cooling and also saves gasoline.
