I have a block heater in my 2009 (not 95, oops!) ML320 Bluetec. The dealer installed the cable, too.

But no specs. So I need to know stuff like:

- Power usage?
- Does it have a thermostat or is it a dumb heater?
- Do i leave it on overnight or just plug in in the AM before leaving?
- what else do I need to know??

Any help welcome. Dealer said "there are no specs"...

I live in the snow belt north of Toronto, and have no garage, so this is of some importance to me! Starting at -20C sounds like it is being torn apart.
