Sport Button
Pressing the "Sport" button (1) activates the Dynamic Driving Control function and selects sportier transmission performance (shorter gearshift times). This function can also be selected in cruise mode.
The request signal is monitored by the MS45 ECM which transmits the signal to the SMG and EPS Control Modules.
If there are no faults in the Control Modules, the EPS Control Module illuminates the function light in the Sport button.
