I haven't drive my sl55 in two weeks and after i started this morning, that message pop up on the ddash, i looked up in the manual and see nothing about "not available",???? has any one see this message before and what's the solution???

thanks in advance for the response

it is probably low battery voltage. get it charged, turn car off, restart.

thanks boss

that's exactly the case, i started the car and let it run for 30 minutes, turn off and started again, it's gone,,,,
