[SD ///M4]

There is no "Auto sport+" setting for "Shifting".

Unrelated to the M Drive settings (throttle, suspension, steering), the transmission is in either Drive Mode (automatic) or Sequential Mode (manual). The responsiveness of shifting in either mode is controlled by DriveLogic, the button directly aft of the shift lever.

In Drive Mode you have your choice of three settings:
▷ 1: efficient driving.
▷ 2: relaxed driving.
▷ 3: sporty driving.

In Sequential mode, you have your choice of three settings:
▷ 1: comfortable shifting operations.
▷ 2: sporty, fast shifting operations.
▷ 3: maximum shifting speed, including Launch Control

These settings are often referred to D1, D2, or D3 for Drive Mode and S1, S2, and S3 for Sequential Mode. You can save all of these settings to either M1 or M2 button.
