Can I drive car with red abc drive carefully light on

What is your question?

ABC red light is on all the time and I can't select any other function on the steering wheel thumb switch. Car is level with no other apparent suspension issues. I see no leaks and the hydraulic reservoir is full. Can I still drive the car until the problem is fixed?

What makes this problem better or worse?

Nothing. No other signs of a problem.

How long has your 2005 Mercedes-Benz SL500 had this problem?

Appeared a month ago, but haven't driven it much.
