Knowing how to maintain your car's tire pressure can help reduce wear on the tires and helps ensure you're getting good gas mileage. Checking your tire pressure includes finding the recommended pressure, checking the PSI and inflating or deflating your tires accordingly.

Routinely checking and changing your car's oil is essential to keeping its engine in running condition. Check your oil each month and change it as directed in the car's owner's manual.

There are several fluids that should be kept at the appropriate levels to help keep your car running properly.

• Engine oil
• Coolant
• Power steering fluid
• Brake fluid
• Transmission fluid

Take your car to a technician if the check engine light comes on. Trained technicians can diagnose the problem through the car's on-board diagnostics (OBD-II) port.
