You probably bought your 2007 Nissan Maxima because of its power, its look and its technological capabilities (such as GPS navigation, live traffic data and Bluetooth phone interface). Like any responsible car owner, you want to keep your Maxima in good running order. If you notice what looks like an open vase with an exclamation point in the middle of your dashboard, your tire pressure is low. Filling your tires with air will reset this sensor and keep you safer on the road.
Visit a service station, and safely park your vehicle near the air compressor. Park in a place where you can reach each tire with the air compressor's hose. Shut the engine off.
Work your way around the vehicle, checking each tire's pressure with a tire gauge. To use a tire gauge, remove the valve cap on one of your tires. Press the tire gauge briefly and firmly into the valve stem to get a reading; remove the gauge, and note the reading. It's easiest to check and fill each tire before moving to the next tire. If you check all the tires before adding air, you'll have to remember the standing pressure of each tire.
Fill each tire to its "cold" tire pressure. Check the manufacturer's Tire and Loading Information (typically printed on the outside of tires) to find the recommended pressure. Use the tire-pressure gauge to ensure that you have the right pressure. Fill your tires before extended driving time, not when they are "hot."
Start your vehicle, and drive for about a mile. The "low tire pressure" warning on your dashboard should reset. If the sensor does not reset, visit a Nissan dealer or an automotive mechanic; a more serious problem could be present in your vehicle.
