How can I activate Audi's Lane Change Assist feature?

I recently purchased an Audi vehicle and noticed it comes with Lane Change Assist. However, I am not sure how to activate this feature while driving. Can anyone provide guidance on how to use this feature?

To activate Audi's Lane Change Assist feature, simply toggle the switch located on your driver's side door. Once turned on, the vehicle will use its sensors and cameras to monitor your blind spots and alert you if there is a vehicle in your path when changing lanes. This feature can help improve your overall driving safety.

Activating Audi's Lane Change Assist feature is simple and can be done with the touch of a button. Just press the button located on the center console and you're all set. This feature is especially useful when driving on busy highways or during rush hour traffic. Just remember to always check your mirrors and use your turn signal before changing lanes.
