you need radio code b/c battery went dead or was disconnected. Post in the radio sticky thread to get code.

As for the others (and maybe why your battery went dead) look into your ignition switch. Common weak point and simple DIY R&R for $10 (if part order online) or $35-50 if picking up part from local dealer.

Instructions on how to replace ignition switch here from Pedrosgarage.com

Good luck :)

Some functions in these things need a "reboot" .Yours may be included. Thats disconecting the ground for 10 mins. or so. You probably will need the above mentioned radio code to.

ALSO, windows can require a resetting trick of holding the buttons down (or up) in some sequence (detailed around here somewhere). Logic says top might require something similar though I've never heard of it.

Computer cars are touchy and can get all out of wack. Mercedes actually has a procedure on how to disconnect the battery to normalize things, something like this:

1. Charge the battery completely, start the car and let all it idle several minutes, then turn it off.

2. Leave the alarm off, as in doors unlocked, open trunk and allow a few minutes for all of the computers to go to "sleep".

3. Disconnect the negative lead on the battery for 10 minutes.

4. Connect negative terminal, you hear clicks and such as the car wakes up.

5. Wait 10 minutes before opening door, the window may or not drop when you lift handle, if it doesn't lower start car and lower window with switch before closing door.

6. To normalize windows, press the concole switches to close the windows, and hold the switch in close for about 10 seconds, you may hear a click as it remembers.

7. Open the door from inside, the window should now drop, and when you unlatch the roof the windows shouls drop as well.

That info, paraphased comes from a SLK 350 manual, but It's the same concept.

Post you "I need a radio code" in the radio code thread, Loren or one of the other sages will help you there.

Welcome to the family, let us know how it works.
