What is M-D on gear shift on Acura RSX?

In an Acura RSX, the "M-D" on the gear shift indicates "Manual Drive" mode. This allows the driver to have greater control over gear selection by shifting manually rather than relying on the automatic transmission's settings. In this mode, the driver can upshift or downshift as needed, providing a more engaging driving experience. It is particularly useful for situations requiring precise control, such as spirited driving or navigating hilly terrain.
