Got the same message yesterday. Today during driving, electricity started to get critically low. (Oooh yeah, so that is what "low battery" means ...) -- Servo failed, ABS failed, then the heating, the speedomeeter, the display.
Made it back home. Checking in to a mechanics in two days. Will try to recharge battery overnight, maybe it's useable for a short trip tomorrow.
