How do I enable my Audi A4's lane departure warning system?

I recently purchased an Audi A4 and noticed it has a lane departure warning system. How do I activate and use this feature?

To enable the lane departure warning system on your Audi A4, simply press the 'car' button on your control knob, select 'Settings', then 'Assistance Systems', and finally 'Lane Change/Departure Warning' and turn it on. The system will then monitor your vehicle's positioning within the lane and provide a visual and audible alert if you unintentionally drift out of your lane.

In addition to turning on the lane departure warning system, it is important to also adjust the sensitivity of the system. This can be done by going into the 'Setup' menu and selecting 'Lane Change/Departure Warning' to adjust the sensitivity level to your preferences.
