Cars That Replace Old-School Tire Pressure Gauges
"Nissan's Easy-Fill Tire Alert system is a convenient alternative to the inaccurate or sometimes nonexistent, tire-pressure gauges at gas stations," Montoya notes.
When you connect an air hose to the tire and the air starts flowing, the vehicle's emergency lights flash to indicate that the filling process has started. The horn chirps when the tire pressure reaches the recommended setting. If the driver spaces out and keeps filling the tire with air, the car horn honks until the air hose is disconnected. Once the driver has let air out of an overfilled tire, the horn chirps again to signal that the proper tire pressure has been reached.
The Easy-Fill Tire Alert debuted on the 2013 Nissan Altima sedan and will eventually make its way to other Nissan vehicles, states the automaker.
