I've seen that a bunch of times, usually after having the battery disconnected.Started my 03 coupe last night and the dic said remove key wait 10 secs.Turned it off and never saw it again.
I do as it says, then i usually don't see the message again. If that's the first time you've seen it, I'd just blow it off. If you see it every time, it's a different story. :thumbsup:
