I sort of followed the run in period.

Initially, you want tyres and brakes to bed in properly.

Then you need to keep it within your limits (sensible ones) as you learn how to drive the car and interact with things like Idrive, adaptive lights etc as you drive.

The engine needs plenty variation once at temperature, drive in Eco, comfort, sport.
When you get used to the car try it with stick to the left in comfort and in sport, get used to using paddles.
Got pro media? Practice with setting it up and using diverts while on the move.

Most of all have fun and enjoy.
