Understanding BMW's Condition Based Service (CBS)

The 2014 BMW X5 xDrive35i utilizes BMW's Condition Based Service system rather than traditional fixed-interval maintenance. Sensors and special algorithms take into account the driving conditions of your vehicle—including driving style, distances traveled, and engine operating parameters—to determine maintenance requirements . The system makes it possible to adapt the amount of maintenance to your individual user profile .

Service information is stored in the vehicle's remote control, allowing your Service Advisor to read this data and suggest the appropriate service procedures for your vehicle . If the vehicle battery has been disconnected for storage periods, time-dependent maintenance procedures such as brake fluid and engine oil should be verified by a service center .
