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:
Engine oil
Brakes – front and rear separately
Microfilter
Brake fluid
Spark plugs
Vehicle check
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.

Vehicle Check
Maintenance work (continued)
• Brake system connections and lines: check for leaks, damage and correct positioning
• Underbody, incl. all visible parts (i.e. trans- mission, rear axle, fuel lines, exhaust
system), check for damage, leaks and
corrosion

• Final Inspection: Road test with check of – Brakes
– Steering
– Shock absorbers (visual)
– Transmission
