Previously, after towing I could get the instrument cluster center gauge to go back to my choice. After a recent disconnect the Towing Grade indicator ALWAYS comes on upon starting engine. I have to manually set to choice (like compass or fuel economy). In the past, once I changed it, it would still be there when I restarted the engine. I've been through the manual. Am I missing an easy choice? Is there a simple "reboot"? Thanks!
