What to do if I will not be driving the car for a month

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ooooo! I hope you're getting to go on a tropical getaway! If you're heading out for the month, my suggestion is to buy a trickle charger so the battery doesn't drain. Of course, I'd consult Mercedes first. Some Mercedes have what I call a "starting" battery. It's a smaller batter that turns the starter over. The other battery is usually much bigger and holds memory, among other things, allowing the car to shut the computers as needed. Good luck and have fun!
