The light on the dashboard is not turning off. It looks like a horse shoe with an exclamation mark in the middle. I’d like to know if this is due to lack of tire air pressure and how I can turn it off.
Have you looked in your glove-box for a handy little book called “The Owners Manual”??
I believe that is a brake wear indication.
Every symbol that I’ve seen that looks like the OP is describing is for low air pressure in one or more tires.
