Tiguan L doesn't need to change the glass. Because of the difficulty in construction, the accuracy of hand-glued cameras can't achieve this high-end intelligent behavior at all. Accessories for maintaining the original lane of Tiguan L include: high-equipped camera, camera cover, wire harness and high-equipped front windshield.

Lane keeping system is a common intelligent driving assistance system in German cars, also called lane departure warning system. The working principle is that the camera attached to the front of the windshield detects the lane markings on the road and keeps the car driving in one lane. If the vehicle deviates from the lane, the vehicle system will shake the steering wheel or prompt the driver to control the steering wheel. This can prevent long-distance riders from falling off the track after falling asleep because of fatigue driving.
