How to replace battery on 2009 Mercedes Benz E350
Hello again guys. I posted a thread earlier about having problems with the AM/FM/Satellite radio displaying a device unavailable message after my car died and jump starting the car. I read that disconencting and reconnecting the battery or replacing the battery all together may fix the problem. I need to know the exact procedure for disconnecting and reconnecting the main battery. Do you disconnect the ground or positive terminal first or what? I appreciate any and all help. Thanks.

Excellent. Thanks. I'm hoping this will fix the device unavailable problem. I'm hoping disconnecting and reconnecting the battery will fix it or buying a new battery at the most. I hate to think I fried some electronics or something.

Starbrite: Honcho is trying to put up a thread about tips and tricks on the W211. it would be very useful to post a step by step detail on how to check the battery voltage on our cars on that thread.
