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 incon-

venience by computing maintenance inter-

vals 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, driving

conditions have 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 frequent mainte-

nance intervals than a vehicle driven for

50,000 miles for long distances at low

engine speeds primarily at operating temper-

ature.

The advanced technologies at BMW have

led to the development of the unique BMW

Condition Based Service System (CBS)

which computes the actual optimum mainte-

nance requirements based not only upon the

accumulated mileage, but taking into

account important factors such as high or

low engine speeds, short or long trip driving,

and condition of the engine oil and brake

pads.

The BMW Maintenance

System

Condition Based Service CBS

CBS is a further development of the Service

Interval Indicator System. Sensors and

sophisticated algorithms take even more

detailed account of the various conditions of

vehicle use.

The remaining times for selected mainte-

nance tasks as well as any legally prescribed

dates are displayed to you individually:

䉯 Engine oil

䉯 Brakes – front and rear separately

䉯 Microfilter

䉯 Brake fluid

䉯 Spark plugs

䉯 Vehicle check

䉯 Required State Inspection(s)

CBS thus determines the current and future

maintenance requirements. This data can

also be read from the vehicle key by your

BMW Service Advisor and used to propose

the optimum scope of maintenance.

Have maintenance and repair work

performed by your BMW center. Make sure

that the maintenance work is stamped in this

Service and Warranty Information Statement.

These entries are the evidence of regular

maintenance of your vehicle and a require-

ment for warranty claims.
