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 con-

ventionally been specified based upon accumu-

lated mileage. However, the type of driving condi-

tions 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 re-

quires more frequent maintenance intervals than a

vehicle driven for 50,000 miles for long distances at

low engine speeds primarily at operating tempera-

ture.

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 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 oper-

ate 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 in-

cluded in each of the elements of the BMW

Maintenance System is found on pages 4-13.

These elements are as follows:

Quality Certification I will be performed by your

selling center and certified on the following page.

The Z8 requires a 1200 Mile Service, which is

not displayed by the Service Interval Indicator.

This service consists of changing the oil for the

rear axle differential.
