The manual shift mode gives you the feel of driving a manual transaxle vehicle by allowing you to operate the selector lever manually. This allows you to control engine rpm and torque to the drive wheels much like a manual transaxle when more control is desired.
To change to manual shift mode, shift the lever from D to M.

NOTE
Changing to manual shift mode while driving will not damage the transaxle.
To return to automatic shift mode, shift the lever from M to D.
NOTE
Active Adaptive Shift (AAS)
