spark plugs replace BMW 325CI CONVERTIBLE 2005 Owners Manual

4 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 changed with the
engine at operating temperature.
Note: change oil at least once a year.
Your BMW is factory-equipped with a
newly-developed synthetic engine oil. At
the time of the printing of this booklet BMW
High-Performance Synthetic 5W-30 Oil
(Part Number 07 51 0 017 866) and Mobil 1
5W-30 and 5W-40 oils are strongly
recommended and approved by BMW for
the 3 Series models covered in this booklet.
BMW is evaluating various synthetic oils for
inclusion in our list of recommended motor
oils.
For the most current list of synthetic oils,
please contact your BMW center, or call
BMW of North America at 1-800-831-1117.
You can also obtain this information from
our website, www.bmwusa.com/.
It is recommended to check engine oil level
whenever fuel is added to the vehicle.
If you need to add oil between oil changes
and are unable to obtain BMW High Per-
formance Synthetic Oil, Mobil 1 or another
special oil on the list, use a synthetic oil
with an API rating of SJ or higher.
– Inspection I: Major vehicle maintenance
as specified in the following pages under
Inspection I.
– Inspection II: Additional major vehicle
maintenance as specified in the following
pages under Inspection II.
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.– Oxygen Sensor Service: The oxygen sensor
deteriorates strictly on a mileage basis and
must therefore be replaced every 120,000
miles (3 Series with optional Sequential
Manual Gearbox (SMG) 100,000 miles), to
maximize vehicle fuel economy and
minimize exhaust pollution. In the SULEV
(PZEV) models, the oxygen sensor must
be replaced every 150,000 miles. The
replacement of the oxygen sensor is
required under the terms of the appli-
cable BMW emission system warranties.
– Spark Plug Service: Replace spark plugs
every 100,000 miles. Your BMW is
equipped with platinum-tipped spark plugs.
These allow a longer service life than
conventional spark plugs.
– Automatic Transmission Service: Change
ATF every 100,000 miles.
The engine coolant has a lifetime rating and
does not need to be changed.
For your convenience, you may also wish to
have your BMW center perform any necessary
operations 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
Warranty Information Booklet. 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 techno-
logical advances not only to the design and
production of your vehicle, but also to comput-
ing of the optimum maintenance interval for
your type of operations and driving style. Your
BMW center has made a substantial invest-
ment in unique BMW special service tools to
enable his BMW factory trained service
technicians to perform quality repairs on your
BMW in minimal time. He/she looks forward to
serving your every service need and to help
maximize your satisfaction with your BMW, its
longevity, and resale value.

New Vehicle Limited Warranty -
2005 3 Series Models (except M3)
(Valid only in the U.S.A. and
Puerto Rico)

34 parts are warranted by their manufacturer to
be equivalent to genuine BMW parts in
performance and durability. BMW NA
assumes no liability under this warranty with
respect to parts other than genuine BMW
parts.
However, the use of non-BMW replacement
parts or non-EPA certified parts does not
invalidate the warranty on other components,
unless non-BMW parts or non-EPA certified
parts cause damage to warranted parts.
What is not covered
This warranty does not cover malfunctions
caused by any of the following: accident, flood,
misuse, improper adjustment, modification,
alteration, tampering, disconnection, improper
or inadequate maintenance, use of leaded fuel
or fuels containing more than 10% ethanol, or
other oxygenates with more than 2.8% oxygen
by weight (i.e., more than 15% MTBE or more
than 3% methanol plus an equivalent amount
of co-solvent).
The replacement of maintenance parts, such
as spark plugs, filters and similar items used in
required maintenance services, the repair or
replacement of maintenance parts beyond the
first required inspection/maintenance, or if the
part has been replaced earlier for reasons
other than it being defective.
The car or any part of the car unless a failure
causes the car to fail to conform to applicable
emission regulations.
Any car on which the odometer has been
replaced or altered and the true mileage
cannot be determined.
The car, if the vehicle identification number is
altered or cannot be read, or if the car has
been declared a total loss or sold for salvage
purposes.
General
These warranties give you specific legal rights,
and you may also have other rights which vary
from state to state.THE DURATION OF ANY IMPLIED WARRAN-
TIES, INCLUDING THE IMPLIED WARRANTY
OF MERCHANTABILITY, IS LIMITED TO THE
DURATION OF THE EXPRESS WARRANTIES
HEREIN.
BMW NA HEREBY EXCLUDES INCIDENTAL
AND CONSEQUENTIAL DAMAGES, INCLUD-
ING LOSS OF TIME, INCONVENIENCE, OR
LOSS OF USE OF THE VEHICLE, FOR ANY
BREACH OF ANY EXPRESS OR IMPLIED
WARRANTY, INCLUDING THE IMPLIED
WARRANTY OF MERCHANTABILITY,
APPLICABLE TO THIS PRODUCT.
Some states do not allow limitations on how
long an implied warranty lasts, or the exclu-
sion or limitation of incidental or consequential
damages, so the above limitations and
exclusions may not apply to you. Additionally,
if you are a California, Maine, Massachusetts
or Vermont resident and your vehicle is
registered in that state, your vehicle is eligible
for California Emissions Warranty coverage.
These federal warranty provisions also apply
to all vehicles sold in all U.S. states and
territories regardless of whether a state has
enacted state warranty provisions that differ
from the federal provisions.

39 demonstrates that such lack of required
maintenance is a direct cause of the emission
control system failure. The instructions for
required maintenance and use can be found
in the Owner’s Manual and in the Service
section of this Statement.
It is strongly recommended that any replace-
ment parts used for maintenance, repair or
replacement of emission control systems be
genuine BMW Service Parts or BMW
Authorized Remanufactured Parts. Without
invalidating this warranty, the owner may
elect to have maintenance, repair or
replacement of the emission control systems
performed by any automotive repair estab-
lishment, or elect to use parts other than
BMW Authorized Remanufactured or
genuine BMW Service Parts. However, the
cost of such service or parts will not be
covered under this warranty, except in
emergency situations. In an emergency
situation, where an authorized BMW center
is not reasonably available or a warranty
replacement part is not available within 30
days, repairs may be performed at any
available service establishment or by any
individual using any replacement part.
A repair not completed within 30 days
constitutes an emergency. BMW NA will
reimburse the owner for such emergency
repairs (including labor, parts and diagnosis
not to exceed BMW suggested retail price for
all warranted parts replaced and labor
charges based on the manufacturer’s recom-
mended time allowance for the warranty repair
and the geographically appropriate hourly
labor rate) that are covered under this
warranty. Replaced parts and paid invoices
must be presented to a BMW center as a
condition of reimbursement for emergency
repairs not performed by a BMW center.
The use of replacement parts, which are not of
equivalent quality, may impair the effective-
ness of emission control systems. If other than
genuine BMW Service Parts or Authorized
Remanu-factured Parts are used for mainte-
nance, repair or replacement of components
affecting emission control, the owner should
obtain assurances that such parts are war-ranted by their manufacturer to be equivalent
to genuine BMW parts in performance and
durability. BMW NA assumes no liability under
this warranty with respect to parts other than
genuine BMW parts.
However, the use of non-BMW replacement
parts does not invalidate the warranty on other
components, unless non-BMW parts cause
damage to warranted parts.
What is not covered
This warranty does not cover malfunctions
caused by any of the following: accident, flood,
misuse, modification, alteration, tampering,
disconnection, improper or inadequate
maintenance, except if performed by an
authorized BMW center doing warranty repair
work, use of leaded fuel or fuel other than as
specified in the Owner’s Manual.
The replacement of maintenance parts, such
as spark plugs, filters and similar items used in
required maintenance services or the repair or
replacement of maintenance parts beyond the
first replacement interval.
Any car on which the odometer has been
replaced or altered and the true mileage
cannot be determined.
The car, if the vehicle identification number is
altered or cannot be determined, or if the car
has been declared a total loss or sold for
salvage purposes.

from state to state.
