Human: My car's air tire pressure alert went off. What does that mean? Assistant: 
That’s actually a safety feature designed to warn you when your tires are under-inflated. Under-inflated tires can be dangerous and cause a lot of damage to your car, so it’s important to keep your tires properly inflated. Here are some general guidelines to check your tire pressure:
-Inspect your tires regularly and check the tire pressure using a digital pressure gauge.
-Tire pressures should be checked when the tires are cold, before driving and before mounting and unmounting tires.
-Tire pressures should be checked at least once a month, but should be checked more frequently in hot weather.
-Tire pressures should be checked when the vehicle is not loaded, and when the tires are fully warmed up and driven on dry pavement.
-Tire pressures should be checked before every trip, and when the tires are at the recommended cold (36-42 degrees Fahrenheit) inflation pressure.
-Inflate tires to the manufacturer-recommended pressure and do not over-inflate. Over-inflation can lead to excessive tire wear and can impact fuel economy.
-Know your vehicle's recommended tire pressures and have your tires checked regularly by a professional.
