Intervals
Time intervals should be followed using the
maintenance interval as indicated by the BMW
Service Indicator lights on the check control
panel in the dashboard.
Maintenance intervals on motor vehicles have
conventionally been specified based upon accu-
mulated 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, 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 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 sav-
ings to owners of vehicles subjected to light
duty.
This BMW Service and Warranty Information
Booklet should be presented to your BMW cen-
ter when maintenance is required. Your BMW
center will stamp this book documenting the
services or maintenance performed.
Maintenance Program
The Service Interval Indicator consists of a
mileage reading, and the inscriptions “OIL SER-
VICE” and “INSPECTION”.
Whenever the ignition is switched on, the dis-
play 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 exceeded,
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 with-
out delay.
After each maintenance is performed the ser-
vice indicator is reset in order to compute the
next service interval.
If the Service Interval Indicator displays an illogi-
cal reading, or if there is no display, consult a
BMW center.
If the speedometer, tachometer or coolant tem-
perature gauge should develop a fault, the ser-
vice interval indicator will probably cease to
operate correctly as well, since it depends on
correct speed, distance and temperature read-
ings. 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 Program is found on page s4-9.
These elements are as follows:
