Maintenance
BMW Maintenance System
The BMW Maintenance System helps
maintain your vehicle's road safety and
operational safety. Comfort-related
aspects, such as the timely change of
filters for the air inside the vehicle, are
taken into consideration. The goal is to
optimize maintenance with respect to
low total cost of ownership.
If you should sell your BMW one day,
consistent service and maintenance will
prove to your advantage.
Service interval display
The service interval display shows you
when an oil service, an inspection –
always alternating between I and II – or
a brake fluid change is due. The special
feature is that the service intervals are
calculated according to your BMW's
individual driving conditions instead of
from fixed mileage increments.
The technology developed for this
takes your personal driving style into
account, as well as your BMW's driving
conditions. After all, short-distance
driving, i.e. frequent cold starts, or driv-
ing off at high engine speeds, affects
your BMW differently from long-dis-
tance driving with the engine at consis-
tent operating temperature.
Have a break-in inspection per-
formed at approx. 1,250 miles/
2,000 km regardless of the service
interval indicated on the display.

Special feature regarding engine
oil change
The calculation of the service intervals
covers practically every kind of operat-
ing situation. If you drive very rarely,
however, you should have the oil
changed at least every two years, since
engine oil deteriorates over time
regardless of use.

damage from rocks or gravel at the
same time, depending upon operating
conditions.
