Maintenance Program
The BMW Maintenance Program has been
devised with the following objectives: to maxi-
mize vehicle safety, reliability, and resale value by
minimizing breakdowns resulting from wear, and
minimizing cost and inconvenience by comput-
ing maintenance intervals based upon the spe-
cific manner in which each individual vehicle is
driven.
Maintenance intervals on motor vehicles have
conventionally been specified based upon accu-
mulated 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 accelera-
tion requires more frequent maintenance inter-
vals 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 Condition
Based Service System (CBS) which computes
the actual optimum maintenance 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 driv-
ing, and condition of the engine oil and brake
pads.
The BMW Maintenance Program
Condition Based Service CBS
CBS is a further development of the Service
Interval Indicator System. Sensors and sophisti-
cated algorithms take even more detailed
account of the various conditions of vehicle use.
The remaining times for selected maintenance
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 mainte-
nance work is stamped in this Service and War-
ranty Information Statement. These entries are
the evidence of regular maintenance of your vehi-
cle and a requirement for warranty claims.

The vehicle’s current service status is automati-
cally saved in the vehicle’s ignition key. The Ser-
vice Advisor at your BMW center has a device
called a key reader. When your Service Advisor
inserts your key into the key reader, all pertinent
vehicle and servicing data will be available, and a
customized maintenance checklist is printed out
based on the specific operations called for by the
Condition Based Service.
The performance of certain subsequent mainte-
nance elements, as required by the BMW New
Vehicle Limited Warranty, will be specified at
intervals computed by the BMW Service Interval
Indicator as follows:
– Oil Service: Engine oil should be changed with the engine at operating temperature. Note:
Change oil at least once a year. All 2006 model year 6 Series are factory-filled
with BMW High Performance Synthetic oils. At
the time of the printing of this booklet, the follow-
ing oils are strongly recommended and approved
by BMW:
•
BMW High Performance 5W-30 Synthetic Oil
(BMW part number 07 51 0 017 866)
• Mobil 1 5W-30
• Mobil 1 5W-40
BMW is evaluating various synthetic oils for
inclusion in our list of recommended engine oils.
For the most current list of synthetic oils, please
contact your BMW center, or call BMW of North
America, LLC. at 1 800 831-1117. You can also
obtain this information from our website,
www.bmwusa.com/.
BMW recommends that you check your engine
oil level whenever you add fuel to your vehicle. If
you need to add oil between oil changes and are
unable to obtain BMW High Performance Syn-
thetic Oil, Mobil 1 or another special oil on the
list, use a synthetic oil with an API rating of SH or
higher.
The following maintenance elements must be
performed at the mileage/time stated (time inter-
vals begin from the vehicle’s production date):
– Brake Fluid Service: Change brake fluid every two years, or when specified by CBS.
– Oxygen Sensor Service: The oxygen sensor deteriorates strictly on a mileage basis and
must therefore be replaced every 120,000
miles to maximize vehicle fuel economy and
minimize exhaust pollution.
– Spark Plug Service: Replace at 100,000 miles, or when specified by CBS.
