Welcome to the forum and glad you are enjoying your Crosstar.
The safety systems can be disabled but most reset to active following power off.
I found the system which detects road departure to be over sensitive whilst driving on narrow rural roads, typically without road markings.
However, the sensitivity of the system can be adjusted using the touch screen menu and, after reducing the sensitivity, I find the system far less intrusive.
There are also options to disable audible warnings for some of the safety alerts, removing the annoying beeps.
When I initially had the system set to default sensitivity, the road departure alerts were triggering in close succession whilst driving along my local rural roads, so much so that the system automatically deactivates for a while, then subsequently automatically reactivates after some time.
A roads and B roads with decent boundary markings were generally OK; grass verges transitioning to dirt on narrow roads, without line markings, seemed to be the major culprit for false triggers but I now only get a couple of alerts and these are always at the same point on the journey, which was previously accompanied by a multitude of wheel tugs and a cacophony of bleeps, some from the car and some from the driver!
