What’s that light on the dashboard mean? Here’s a list! Parking brake, low oil, low coolant, ABS, high beams, tire pressure, low fuel, and all the dozens of others. They’re shown here with color codes so you can see which mean DO NOT DRIVE ANOTHER INCH and which mean “If you get around to it before 2025, that’s cool.”
These are often called “idiot lights” because they don’t say anything about why the problem is happening.
