The other day I got a light on my dash for tire pressure. So it was the pic of the tire with the exclamation mark in it. I have aftermarket tires with no we sensors. And I have non navigation. So the DIC is what tells me to check tire pressure. I clear it and all is good. The light on the dash according to the owners manual is for the CTS-V with non nav units. It says the CTS will get the DIC display. So, does anyone know why I am getting V lights on my dash? Has this happened to anyone?
