Low Tire Pressure

Modern cars come with tire pressure monitoring systems and the little exclamation point inside of a half-circle merely means one or more of your tires have low pressure. If you see this sign don't freak out. Instead, find a safe place to stop and inspect your tires. If they look a bit low, carefully make your way to the nearest gas station to fill them with air. On most cars, this light will go away on its own after you've topped the tires off.
