Maintenance System

The BMW Maintenance System has been

devised with the following objectives: to

maximize vehicle safety, reliability, and resale

value by minimizing breakdowns resulting from

wear, and minimizing cost and inconvenience

by computing 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

accumulated mileage. However, the type of

driving conditions has 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, pro-

longed periods of idling, stop-and-go driving,

and high engine speeds during acceleration

requires more frequent 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 service

interval indicator which computes the actual

optimum maintenance requirements based

not only upon the accumulated mileage, but

taking into account important factors such as

engine coolant temperatures, high or low

engine speeds, short or long trip driving, and

number of vehicle starts. The maintenance

interval may therefore be maximized with

considerable savings to owners of vehicles

subjected to light duty.

The Service Interval Indicator consists of a

mileage reading, and the inscriptions “OIL

SERVICE” and “INSPECTION”.

Whenever the ignition is switched on, the

display shows the next scheduled type of

service and the remaining distance until the

service should be performed. The distance is

based on your driving style.

If the maintenance interval has been ex-

ceeded, a “—” symbol reminds you of the

urgent need for servicing. In the interests of

road safety and reliability, you should avoid

driving your BMW when the “—” symbol is

showing, and have the essential maintenance

work performed without delay.

After each maintenance is performed the service

indicator is reset in order to compute the next

service interval.

If the Service Interval Indicator displays an

illogical reading, or if there is no display, consult

a BMW center.

If the speedometer, tachometer or coolant

temperature gauge should develop a fault, the

service interval indicator will probably cease to

operate correctly as well, since it depends on

correct speed, distance and temperature

readings. The fault must be located and rectified

by a BMW center.

A detailed list of all maintenance operations

included in each of the elements of the BMW

Maintenance System is found on pages 6-9.

These elements are as follows:
