How can I enable automatic start/stop function in my BMW 2 Series?

I recently purchased a BMW 2 Series and I was wondering if there is a way to enable the automatic start/stop function. I've read about its benefits in terms of fuel efficiency and reducing emissions, but I can't seem to find it in my car's settings. Any advice would be greatly appreciated.

Yes, the automatic start/stop function can be activated through the iDrive system. Go to the 'Vehicle' tab, then select 'Settings' and then 'Driving modes'. There, you can select 'Efficient' mode which will enable the start/stop function.
