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.
with the following objectives: to maximize vehicle
safety, reliability, and resale value by minimizing

intervals based upon the specific manner in which

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 re-
quirements; 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
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 System which computes the actual opti-
mum maintenance requirements based not only
upon the accumulated mileage, but taking into ac-
count important factors such as engine coolant tem-
peratures, high or low engine speeds, short or long
trip driving, and number of vehicle starts. The main-
tenance interval may therefore be maximized with
considerable savings to owners of vehicles sub-
jected to light duty.

The
Service Indicator consists of five green,
one yellow and one red Iight-emitting-diodes
(LEDs) and the inscriptions “OIL SERVICE” and
“INSPECTION”.

If the speedometer, tachometer or coolant tem-
perature gauge should develop a fault, the Ser-
vice lndicator will probably cease to operate cor-
rectly as well, since it depends on correct speed,
distance and temperature readings. The fault
must be located and rectified by a BMW center.
