convenience group
Just took my 2005 sl500 out of winter storage and the read out says convenience group not available. It was stored with battery tenders on both batteries and both are still charged. Any ideas? Can I reset? Looking for help.

Assuming that you mean 'consumers unavailable', that is low voltage on your consumer (trunk) battery. Drive it or let it idle for 10-15 min. and it should go away. If it doesn't, or comes back in a couple of days, you might need a new battery.
