The intelligent maintenance system CBS permanently monitors oil levels and the degree of wear and tear on individual components of your BMW. It also checks the time/mileage recommendations for fixed services and it analyses this data and tells you when a service is next due.
Data can be checked at a glance on your Info Display, which automatically gives you four weeks' notice. The iDrive Control Display gives you exact information on which component needs a check, so you can plan your service appointments well in advance and avoid any unnecessary maintenance work. CBS information can also be accessed through non-iDrive models.
