I wonder what that little horse shoe means, lol? I actually had a friend ask me that question when they saw the low tire pressure symbol. Are you the type of person that ignores warning symbols or check engine light warnings. I usually take care if it immediately but I know a lot of folks who do not. These days it’s pretty easy to find out what the problem is by dropping by your neighborhood auto parts store or checking it yourself with a diagnostic testing tool. You can get them online for anywhere from $15.00 to $50.00. Happy motoring.
