Automatic Engine Start-Stop Function: Notes

The new automatic engine start-stop function (MSA) is a basic element within the array of measures designed to reduce CO2 emissions. By automatically switching off the engine whenever the vehicle is stationary this system reduces fuel consumption. The restart also takes place automatically as soon as the corresponding switch-on conditions required for switch-on are met. MSA is being introduced in BMW 1-Series, 3-Series and MINI vehicles equipped with manual transmission and 4-cylinder engine. Additional engine versions and vehicles with automatic transmissions are slated for subsequent introduction.

The marketing designation is Automatic Start/Stop Function.
