Intervals
Time intervals should be followed using the
maintenance intervals as indicated by the BMW
Service Interval Display.
Maintenance intervals on motor vehicles have
conventionally been specified based upon accu-
mulated mileage. However, driving conditions
have a major influence on routine maintenance
requirements; distance traveled is only one of
the significant factors. A vehicle driven for
50,000 miles of short trips in the city with
numerous cold starts, prolonged periods of
idling, stop-and-go driving, and high engine
speeds during acceleration requires more fre-
quent maintenance intervals than a vehicle
driven for 50,000 miles for long distances at low
engine speeds primarily at operating tempera-
ture.
The advanced technologies at BMW have led to
the development of the unique BMW Condition
Based Service (CBS) system which computes
the actual optimum maintenance requirements
based not only upon the accumulated mileage,
but taking into account important factors such
as high or low engine speeds, short or long trip
driving, and condition of the engine oil and
brake pads.
Condition Based Service (CBS)
CBS is a further development of the Service
Interval Indicator System. Sensors and sophisti-
cated algorithms take even more detailed
account of the various conditions of vehicle use. The remaining times for selected maintenance
tasks as well as any legally prescribed dates are
displayed to you individually:

Engine oil
 Brakes - front and rear separately
 Microfilter
 Brake fluid
 Spark plugs
 Vehicle check
 Required State Inspection(s)
CBS thus determines the current and future
maintenance requirements. This data can also
be read from the vehicle key by your BMW Ser-
vice Advisor and used to propose the optimum
scope of maintenance.
Disconnecting the battery during periods
of long-term storage will interrupt the
calculation of time-based services. Have all
items requiring time-based maintenance, such
as brake fluid and coolant, and possibly also the
engine oil and microfilter, brought up to date by
your BMW center. Also see the section on bat-
tery care on page 15 of this statement.
