Oil changes performed outside the recom-
mended maintenance intervals as indicated
by the Service Interval Indicator
Maintenance Upgrade Option
Please contact your authorized BMW center for
information and availability on the optional Main-
tenance Program Upgrade for coverage up to
6 years and 100,000 miles.
Intervals
Time intervals should be followed using the
maintenance interval as indicated by the Condi-
tion Based Service (CBS) 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
temperature.
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
Brake fluid
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, brought up to date by your BMW
SAV center. Also see the section on battery care
on page 15 of this statement.

briefly appears when you switch on the ignition.
The Info Display immediately switches to
its compute mode when you press one
of the two buttons in the turn signal indicator
lever.
Control Display screen contents
The current Status of Service items determined
by the CBS are shown in the Control Display.
You can also view additional information on the
service and maintenance requirements.
