Introduction (for SULEV (PZEV)
only)
Certain 2008 328i models are certified to Cali-
fornia’s stringent Super Ultra Low Emission
Vehicle (SULEV) standards and also qualify as a
Partial Zero Emission Vehicle (PZEV) under the
California Air Resources Board Zero Emission
Vehicle program. In addition to very low tailpipe
and zero-evaporative emissions, this PZEV certi-
fication includes a unique warranty when the
vehicle is registered in California and certain
Northeastern states as indicated in the SULEV
(PZEV) section beginning on page 42. SULEV
(PZEV) models registered in Oregon and Wash-
ington are covered by the California Emission
Warranty beginning on page 39. The emission certification standard can be veri-
fied on the Vehicle Emission Control Information
label located in the engine compartment. A rep-
resentative label is shown below; the SULEV
(PZEV) certification is stated after the word
“California.”

The BMW Maintenance Program
The BMW Maintenance Program is a benefit
designed to help reduce the cost of ownership.
This program has been devised with the follow-
ing objectives: to maximize vehicle safety, reli-
ability, and resale value by minimizing
breakdowns resulting from wear, and minimizing
cost and inconvenience by computing mainte-
nance intervals based upon the specific manner
in which each individual vehicle is driven.
2008 3 Series vehicles purchased from any
authorized BMW center in the United States or
Puerto Rico are covered by The BMW Mainte-
nance Program for 48 months or 50,000 miles,
whichever occurs first. 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, which-
ever is earlier.
Any authorized BMW center in the United
States or Puerto Rico will perform the sched-
uled maintenance services on your vehicle at no
expense to you.
Coverage
The BMW Maintenance Program covers all fac-
tory recommended maintenance, as determined
by the Condition Based Service (CBS) system.
Additional items that need replacement due to
normal wear and tear, and that are not covered
by the original New Vehicle Limited Warranty -
such as brake pads, brake rotors, and wiper
blades inserts - are included, provided wear and
tear exceeds BMW wear limits. Any adjustments
required due to normal operating conditions are
also included. See pages 7-8 of this booklet for
additional information.
Exclusions from coverage include the following:
 Items reimbursable under your New Vehicle
Limited Warranty
 Gasoline
 Windshield washer additive (except when in
conjunction with scheduled maintenance)
 Tires, wheel alignment, tire balance and
rotation 
Wear and tear of soft trim items, such as:
seats, carpets, moldings, headliner, door pan-
els and all chrome trim
 Damage detected when performing the rust
perforation inspection
 Damage which results from negligence,
improper operation of the vehicle, wear and
tear or deterioration due to driving habits or
conditions, improper repair, environmental
influences, flood, accident or fire damage,
road salt corrosion, alteration, installation of
non-genuine BMW accessories, or use of
improper, poor quality or contaminated fuel
 Altered or unreadable Vehicle Identification
Number (VIN) or odometer irregularities or
vehicles where the true mileage cannot be
determined
 Maintenance or repair after the vehicle is
deemed a total loss
 Maintenance or repairs performed by other
than an Authorized BMW center within the
United States or Puerto Rico
 Vehicles used in competitive events
 Oil changes performed outside the recom-
mended maintenance intervals as indicated
by the Service Interval Display
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 BMW
Service Interval 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
2

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.

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
