What does the Vauxhall Crossland's LANE DEPARTURE WARNING feature do?

I've noticed a new feature on my Vauxhall Crossland called LANE DEPARTURE WARNING. Can you explain what it does and how it works?

The LANE DEPARTURE WARNING feature uses cameras to monitor the markings on the road. If you start to drift out of your lane without signaling, the system will alert you with a warning sound and flashing light on the dashboard.

This feature is designed to help prevent accidents caused by drifting into other lanes without realizing it. It's especially useful on long drives or when you're feeling tired.

To make sure the LANE DEPARTURE WARNING feature is properly calibrated, it's important to keep the cameras clean and free from obstructions. This will ensure the system can accurately detect the lane markings and give you timely warnings.
