Active Sound Enhancement

Description 

• During driving, the active noise enhancement system improves the quality of engine sound heard in the vehicle by producing a sound via the speakers according to engine speeds and drive mode.
• The active noise enhancement system uses two different types of sound volume. When SPORTS mode is selected with Infiniti Drive Mode Selector, the sound volume is turned up compared to that of other modes.
