Maintenance Program
The BMW Maintenance Program has been
devised with the following objectives: to maxi-
mize vehicle safety, reliability, and resale value by
minimizing breakdowns resulting from wear, and
minimizing cost and inconvenience by comput-
ing maintenance intervals based upon the spe-
cific manner in which each individual vehicle is
driven.
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 accelera-
tion requires more frequent maintenance inter-
vals 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 driv-
ing, and condition of the engine oil and brake
pads.
The BMW Maintenance Program
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 Service
Advisor and used to propose the optimum scope
of maintenance.
Have maintenance and repair work performed by
your BMW center. Make sure that the mainte-
nance work is stamped in this Service and War-
ranty Information Statement. These entries are
the evidence of regular maintenance of your vehi-
cle and a requirement for warranty claims.
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 cen-
ter. Also see the section on battery care on page
15 of this statement.

The distance remaining until your next service
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.

•Replace ventilation microfilter
Front brake
Maintenance work
•Replace brake pads, clean brake pad contact
points in calipers.
•Brake discs: Check surface and thickness, if
necessary replace at extra charge*
Rear brake
Maintenance work
•Replace brake pads, clean brake pad contact
points in calipers.
•Brake discs: Check surface and thickness, if
necessary replace at extra charge*

Vehicle Check
Maintenance work
•Check operation of horn, headlight flasher and
hazard warning flashers.
•Check instrument and control lighting and
heater/air-conditioning blower.
•Check lighting system: turn signals, back-up,
license plate, interior (incl. map, reading lights),
glovebox, flashlight, luggage area lights.
•Safety belts: check condition and function.
•Check windshield wiper and washer jet
positions.
•Body: check for corrosion (except cavities).
•Tires: check tread depth, wear pattern, outer
condition, inflation pressure (also spare tire). If
necessary, correct pressure (also spare).
•Battery: check state of charge (magic eye) and
charge if required.
•Power steering reservoir: Check fluid level.
•Visually inspect all SRS airbag units for torn
covers, obvious damage or attachment of
stickers.
•Rear-view mirrors, optional rear-view camera
•Coolant: check fluid level and concentration.
•Windshield washer and intensive cleaning sys-
tem: check protection level, fluid level, top if
necessary.
•Brake system connections and lines: check for
leaks, damage and correct positioning
•Underbody, incl. all visible parts (i.e. transmis-
sion, rear axle, fuel lines, exhaust system),
check for damage, leaks and corrosion
•Steering components: check for clearance,
leaks, damage and wear
•Final Inspection: Road test with check of
•Brakes
•Steering
•Shock absorbers (visual)
•Transmission
