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 possibly also the engine oil
and microfilter, brought up to date by your BMW
center. Also see the section on battery care on
page 17 of this statement.
Service Interval Display
Info Display screen contents
The distance remaining until your next service
briefly appears when you switch on the ignition.
The Info Display immediately switches to
its compute mode when you press one
of the two buttons in the turn signal indicator
lever.
For certain maintenance operations, you can
view the respective distance remaining or due
date individually in the instrument cluster.
1. Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol appears in the display, accompanied
by the words “SERVICE-INFO”.
2. Press button 2.
3. Use button 1 to scroll through the individual service items.

Green lamps
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.
Symbols
No service is currently required.
The deadline for service or a legally man-
dated inspection is approaching. Please
schedule a service appointment.
The service deadline has already passed.
The current service status is automatically
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 cus-
tomized maintenance checklist is printed out
based on the specific operations called for by
the Condition Based Service.
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 BMW center. 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 2008 model year 3 Series vehicles are facto-
ry-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 10W-40 Synthetic
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 inter-
vals begin from the vehicles 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. For the
328i SULEV (PZEV) models, the oxygen sen-
sor must be replaced every 150,000 miles.
The replacement of the oxygen sensor is
required under the terms of the applicable
BMW emission system warranties.
 Spark Plug Service (not shown in CBS).
Replace at the following intervals:
328i versions: 100,000 miles
335i versions: 45,000 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 center perform any necessary opera-
tions to fulfill any state inspection requirements in
your area concurrent with the maintenance ele-
ments specified above during other repairs.
Should you request more frequent mainte-
nance service, the cost of these services will
not be covered by the Maintenance Program.
BMW has applied the most modern technological
advances not only to the design and production of
your vehicle, but also to computing of the opti-
mum maintenance interval for your type of opera-
tions and driving style. Your BMW center has
made a substantial investment in unique BMW
special service tools to enable BMW factory
trained service technicians to perform quality
repairs on your BMW in minimal time. Your service
technician looks forward to serving your every ser-
vice need and to help maximize your satisfaction
with your BMW, 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 BMW center.
