LOW BATTERY MESSAGE on 2006 Mercedes-Benz E500

DOES THIS MESSAGE INDICATE THE BATTERY IS ON ITS WAY OUT? IF SO, IS THIS MESSAGE A HEADS UP OR IT NEEDS ATTENTION NOW?

THE LOW BATTERY MESS. USUALLY MEANS YOUR AUX. BATTERY IS BAD. IT LOOKS LIKE A GO-CART BATTERY.IT SHOULD BE RIGHT UNDER YOUR CABIN AIR FILTER.BUT YOU STILL WOULD HAVE TO ERASE THE CODE FROM THE BATTERY MODULE.
