I thought the GL had 2 batteries. Could it be the send one?

apparently the second one would trigger a different color battery icon. According to my researches the red indicates the battery itself or the alternator. Inchanged the battery and had the alternator tested it was ok

Replace your auxiliary battery in the trunk. It's about 20 bucks aftermarket from batteries plus.
