Auxilarly Battery Malfunction Msg
I seem to be having an issue with this warning msg appearing on my dash when I go out to start my car on colder mornings. No warning lights come on other then this msg and car drives and shifts totally fine. It seems to only happen on initial start up in the mornings. Any ideas?

Time to put a battery meter to your auxiliary battery and determine if this needs to be replaced it would not be terribly unusual if this was the case
The auxiliary battery is in the trunk and a battery meter is about $30 at RadioShack or Home Depot
Check The cold voltage
