Nissan plans to make its novel "Easy-Fill Tire Alert" system available on all future models it brings to market, beginning in 2013.
This combined safety and convenience feature, which also helps reduce fuel consumption, is already standard on all 2013 Nissan Altima, 2012 Nissan LEAF and 2012 Nissan Quest models.
It will become available either as standard equipment or an option on more vehicles later this year, as Nissan plans to launch five all-new models in the next 15 months.
The "Easy-Fill Tire Alert" system includes a control module that expands on the standard tire pressure warning system to aid drivers in filling tires to the proper air pressure.
First, the vehicle's tire-pressure warning system alerts a driver to a tire with low pressure. On some models, it displays the current pressure and tire or tires that require attention on the instrument display.
When the driver stops to top up the tire with air and air begins flowing into the tire, the vehicle's four-way flashers come on to confirm the process has started. When the tire pressure reaches the appropriate level, the horn then chirps to let the driver know the tire has been properly inflated.
If the driver continues to fill the tire with air, the horn honks more aggressively and the tire is deflated to the appropriate operating level.
"Nissan's 'Easy-Fill Tire Alert' system eliminates the need to keep a tire gauge in your vehicle's glove compartment," said Pierre Loing, vice president, Product Planning, Nissan North America, Inc. "By making this unique Nissan innovation available on all our future products, the guessing and the gauge vanish for our customers."
A recently-released U.S. government study shows that driving on under-inflated tires triples the risk of an accident, and according to the U.S. Department of Energy drivers can improve fuel econom by up to 3.3 percent by keeping tires inflated to the proper pressure.
Additionally, according to professionals, there can be a 3-or-4 psi difference in air pressure readings among different gauges, which the "Easy-Fill Tire Alert" system will overcome.
