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.

No service is currently required.
You can request more detailed information
on every entry.
Turn the controller to scroll through the list,
then confirm the selected entry. Confirm to exit the list.
The vehicle’s current service status is auto-
matically saved in the vehicle’s ignition key.
The Service 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
maintenance 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 5 Series are factory-
filled with BMW High Performance Synthetic
oils. At the time of the printing of this
booklet, the following 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 Synthetic 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 intervals 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 as
follows to maximize vehicle fuel economy
and minimize exhaust pollution: 120,000
miles
- Spark Plug Service: Replace at 100,000 miles, or when specified by CBS.
