Application and function in the safety system

The lane assist display in the right wing mirror is an integral part of the lane change warning and blind-spot monitoring system. It is responsible for:

• local, illuminated warning in the passenger side mirror housing,

Thanks to the use of an original solution designed for Audi, the system maintains factory operating parameters, and the light signals are clear and predictable for the driver.

• compatibility with the geometry of the passenger side mirror housing,
• adaptation to factory wiring and connectors in the door,
• consistent appearance and backlight intensity compared to other interior elements.

Such fitment limits the need for modifications and facilitates installation in service or workshop conditions, while maintaining manufacturer standards.

Component characteristics and installation

As a part from the Mirror parts group, the lane assist display is intended for installation in the right exterior mirror. In practice, this means:

• installation in a dedicated location inside the mirror housing,
• connection to the existing Lane Assist wiring harness,
• maintaining the original position and light angle relative to the driver.

The used component allows for an economical repair of the warning system while maintaining the original specification, which is particularly important for vehicles equipped with advanced driver assistance systems.

Benefits of using an original mirror component

Using a dedicated display in the Audi Q7 4L right mirror provides a number of practical benefits:
