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 com-

puting maintenance intervals based upon the

specific 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 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.

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:

䉯 Engine oil

䉯 Brakes - front and rear separately

䉯 Microfilter

䉯 Brake fluid

䉯 Spark plugs

䉯 Vehicle check

䉯 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.

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

vehicle and a requirement for warranty claims.

Disconnecting the battery during periods

of long-term storage will interrupt the cal-

culation of time-based services. Have all

items requiring time-based maintenance,

such as brake fluid and coolant, and possi-

bly also the engine oil and microfilter,

brought up to date by your BMW center.

Also see the section on battery care on

page 16 of this statement.
