Question Details

2015 C300.  I was away for 15 days and did not use the car.  Upon first use, Auxiliary Battery Malfunction came on red, after driving a few minutes, continued to flash every couple minutes in Gray.  This pattern continued for a few uses (short trips), and has now stopped, after I drove a bit of a distance.  

Should I be worried?

No that is normal. The battery may drain a little when the car is parked for a long time. Once you drive for a while like you did, it will recharge. 

I would recommend checking the age of the battery. You may need a new battery in the near feature.
