Maintenance System SULEV
(PZEV) Models
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 require-
ments; 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
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.

Maintenance System is found on pages 7-10.
