The system works by having the vehicle alert the driver when a tire is inflated properly. To engage the system, the driver must put the vehicle in park, apply the parking brake, and leave the ignition on in the accessory more position.
Once you start filling up a tire, the exterior lights begin to flash, indicating the system is monitoring the change in tire pressure. Once the correct tire pressure is reached, the vehicle’s horn will sound. If the tire is over-inflated, the horn sounds again and is accompanied by the hazards lights flashing three times. There’s no seeking out the what the necessary tire pressure is and no wondering if the air pump gauge is correct. The vehicle does all the work.
It’s a neat system that makes filling up tires easier for people. The system is available on 12 current Nissan models – Altima, Armada, Leaf, Maxima, Murano, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Versa, and Versa Note. According to the National Highway Traffic Safety Administration, four out of five consumers are driving around with improperly inflated tires. Not only do improperly inflated tires harm fuel economy, but it can also hurt the tires’ longevity, wearing the tire unevenly. So far, Nissan has sold 5.3 million vehicles with the system.
