2008 BMW X5 sensor

Oil changes performed outside the recom-
mended maintenance intervals as indicated
by the Service Interval Indicator
Maintenance Upgrade Option
Please contact your authorized BMW center for
information and availability on the optional Main-
tenance Program Upgrade for coverage up to
6 years and 100,000 miles.
Intervals
Time intervals should be followed using the
maintenance interval as indicated by the Condi-
tion Based Service (CBS) display.
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 acceleration requires more fre-
quent maintenance intervals 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
driving, and condition of the engine oil and
brake pads.
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 Ser-
vice Advisor and used to propose the optimum
scope of maintenance.
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
SAV center. Also see the section on battery care
on page 15 of this statement.

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
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 per-
formed 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 every
120,000 miles to maximize vehicle fuel econ-
omy and minimize exhaust pollution.
 Spark Plug Service: Replace at
100,000 miles.
 The engine coolant has a lifetime rating and
does not need to be changed except for sys-
tem repairs.
For your convenience, you may also wish to
have your BMW SAV center perform any neces-
sary operations to fulfill any state inspection
requirements in your area concurrent with the
maintenance elements specified above during
other repairs. Should you request more fre-
quent maintenance service, the cost of these
services will not be covered by the Mainte-
nance Program.
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 BMW SAV
center has made a substantial investment in
unique BMW special service tools to enable
BMW factory trained service technicians to per-
form quality repairs on your BMW in minimal
time. Your service technician looks forward to
serving your every service need and to help
maximize your satisfaction with your BMW, its
longevity, and resale value.

Evidence of Maintenance Work
This BMW Service and Warranty Information
Booklet should be presented to your authorized
BMW SAV center when maintenance is
required. Make sure that confirmation of mainte-
nance work is always entered in this Service and

this for any warranty claims that become neces-
sary, and later on as evidence that your car has
been given the correct and regular maintenance
that justifies its resale or trade-in value.

Coverage begins on the date of first retail sale
or the date the vehicle is first placed into service
as a sales demonstrator, service loaner (SLP) or
company vehicle, whichever is earlier. This war-
ranty continues for a period of 2 years or
24,000 miles, whichever occurs first, except for
specific emissions control components (as
listed on page 34), for which the warranty period
is 8 years or 80,000 miles whichever occurs
first.
This warranty is made subject to the terms and
conditions that apply to the Emission Control
System Warranty and the New SAV Limited
Warranty.
No claim under this warranty will be denied on
the basis of use of a properly installed EPA cer-
tified emission part for maintenance and repair.
A SAV manufacturer may deny an emission per-
formance warranty claim on the basis of an
uncertified replacement part used in the mainte-
nance or repair of an SAV only if the SAV manu-
facturer presents evidence that the uncertified
replacement part is either defective in materials
or workmanship or not equivalent from an emis-
sion standpoint to the original equipment part.
Maintenance, replacement, or repair of emis-
sion control devices and systems may be
performed by any automotive repair estab-
lishment or individual using any certified
part.
Immediately after the SAV has failed an EPA
approved emission short test, your claim can be
made at any authorized BMW SAV center. The
authorized BMW SAV center will honor or deny
your claim within the time period specified by
local or state laws (not to exceed 30 days), to
avoid further penalties or sanctions. lf the claim
is denied, the authorized BMW SAV center will
notify you in writing of the reason(s). The autho-
rized BMW SAV center is required by law to
honor the claim if notice of denial is not received
by the owner within the specified time period.
You may obtain further information concerning
the emission warranties, or report violations of
warranty terms, by contacting the Director, Field
Operations and Support Division (6406J), Envi-
ronmental Protection Agency, 401 “M” Street,

eral Emission Performance Warranty for a period
of two years or 24,000 miles, whichever occurs
first. The specific systems may vary according to
model, therefore, all of the systems listed may
not be used on your SAV. For assistance in

nents within these systems apply to your SAV,
