On the dash when the ice warning light comes , I can’t seem to clear it by pressing the end of the stalk so I can continue to read my other information.
Am I doing anything wrong ? Or does the ice warning light stay on permanently.
Yes, that sounds about right. Despite what it says below, I'm sure that the warning message can be cleared with the _read_ button, but the warning triangle you're stuck with until spring:
Depends on your model year. Pre-2016 dash “facelift” (the one with haptic feedback buttons derived from the Vanquish), it is the “Read” button. On the 2016+ dash, it’s the “i” button.
