The concept

Pressing the Start/Stop button

Pressing the Start/Stop button switches the ignition on or off and starts the engine.

Automatic transmission: the engine starts if the brake is depressed when the Start/Stop button is pressed.

Manual transmission: the engine starts if the clutch is depressed when the Start/Stop button is pressed.
