FRANKLIN, Tenn. — Nissan North America Inc. has developed a novel replacement for the common tire gague — your car.
Nissan is taking tire pressure monitoring to the next level, adding an on-board tire filling assist feature that uses the vehicle's lights and horn to help motorists fill their tires to the proper inflation pressure.
Available standard on 2013 Nissan models, the ”Easy Fill Tire Alert” system combines the tire-pressure warning system with the filling assist feature.
When the government-mandated tire-pressure warning system alerts a driver to a low tire, a dashboard display shows the pressure of the relevant tire or tires, Nissan said.
When the driver stops and starts to refill the tire, the car's four-way flashers come on to confirm that air is going in. When the tire is full, the horn chirps to let the driver know the process is complete.
If the driver puts in too much air, the flashers blink faster and the horn beeps three times. The horn chirps again after enough air is let out to reach proper inflation, Nissan said.
In promoting the feature, Nissan notes that some owners don't keep a tire gauge in their glove box or they or have trouble using them. In addition, professionals say there can be a 3 to 4 psi difference from tire gauge to another. "Easy-fill Tire Alert" eliminates both the guessing and the gauge.
“If you get a low pressure tire warning, you´re not left wondering if you have a serious condition that requires you to stop immediately, or if it's something that allows you to drive home or to the nearest filling station and then fill up,” said Vishnu Jayamohan with Nissan Product Planning and Advanced Strategy
The display shows the driver the pressure for each tire.
