Where is auxiliary battery in 2008 ml550?
Aux. Battery light been on a while. Brakes are locking up. Hoping it has to do with that and not that I'm towing 7k pounds sometimes with this SUV.

The small aux battery is actually located right next to the main vehicle battery under the passenger seat. You will have to remove the main battery to access it, but once you do get the battery out, the aux battery is on the right side of that small compartment. I can't remember whether its a 10mm bolt or small T30 bolt that holds the bracket for the aux battery down.
