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 (CBS) system 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
Brake fluid
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.
Disconnecting the battery during periods
of long-term storage will interrupt the
calculation of time-based services. Have all items
requiring time-based maintenance, such as
brake fluid and coolant, and possibly also the
engine oil brought up to date by your BMW cen-
ter. Also see the section on battery care on page
15 of this statement.

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 SAV 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 at the following
intervals to maximize vehicle fuel economy and
minimize exhaust pollution.
120,000 miles.
– Spark Plug Service: Replace at 100,000 miles,
or as determined by CBS.
– The engine coolant has a lifetime rating and
does not need to be changed.
For your convenience, you may also wish to have
your SAV center perform any necessary opera-
tions to fulfill any state inspection requirements
in your area concurrent with the maintenance
elements specified above during other repairs.
Make sure that confirmation of maintenance
work is always entered in this Service and War-
ranty Information Statement. You may need this
for any warranty claims that become necessary,
and later on as evidence that your car has been
given the correct and regular maintenance that
justifies its resale or trade-in value.
BMW has applied the most modern technologi-
cal advances not only to the design and produc-
tion of your vehicle, but also to computing of the
optimum maintenance interval for your type of
operations and driving style. Your SAV center has
made a substantial investment in unique BMWspecial service tools to enable his BMW factory
trained service technicians to perform quality
repairs on your X5 in minimal time. Your service
technician looks forward to serving your every
service need and to help maximize your satisfac-
tion with your X5, its longevity, and resale value.
Quality Certification I
For a detailed list of items inspected, refer to the
Quality Certification I form provided to the Owner
at time of delivery. A copy of the form is on file at
the selling SAV center.
Special Note
The maintenance requirements for your vehicle
are determined dynamically by the Condition
Based Service (CBS) system . The maintenance
items stated herein reflect the latest information
available at the time of the printing of this state-
ment, and are subject to change. The most cur-
rent maintenance recommendations are available
from your authorized SAV center.
Maintenance summary
The Condition Based Service (CBS) system will
determine the requirement for performance of
the maintenance services described on this and
the following page. These services may be
required either individually or in conjunction with
other maintenance services.
Depending on the vehicle’s use, CBS may calcu-
late service intervals which are different from the
guidelines listed.
