What does the eco mean on the X-Trail?

[CaliLee]

The eco on the X-Trail is an energy-saving mode. When the eco light is on, it indicates that the eco energy-saving mode has been activated. The name eco is derived from the combination of Ecology, Conservation, and Optimization, representing the fundamental design and development philosophy centered on technology, environmental protection, and economic efficiency. These three attributes have become the enduring qualities pursued by the eco intelligent engine family series. The X-Trail adopts Nissan's signature design language in its exterior, with the family-style V-Motion front grille emphasizing a youthful and fashionable appeal. The interior has been upgraded with a central multimedia system integrating multiple smart functions. Under the hood, it continues to be powered by a 2.0L inline four-cylinder naturally aspirated engine.
