BMW Full Maintenance
Programs - 2005 BMW Z4
2.5i, 3.0i
BMW Full Maintenance Programs are a benefit
designed to help reduce the cost of scheduled
and unscheduled maintenance.
2005 BMW Z4 models purchased from any
Authorized BMW center in the United States or
Puerto Rico are covered by Full Maintenance
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 in service as a demonstrator or
company vehicle, whichever is earlier.
Any authorized BMW center in the United
States or Puerto Rico will perform the
scheduled or additional maintenance services
on your vehicle at no expense to you. The
maintenance schedule intervals are based on
normal driving conditions and operation.
Should you request more frequent
maintenance service, the cost of these
services will not be covered by the
Maintenance Program.
Coverage
Full Maintenance covers all factory recom-
mended maintenance, as determined by the
service interval indicator. 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 blade inserts -
are included, provided wear and tear
exceeds BMW specifications. Any adjust-
ments required due to normal operating
conditions are also included. See pages 5-8
of this booklet for additional information.
Maintenance Intervals
Time intervals should be followed using the
maintenance interval as indicated by the BMW
Service Indicator lights on the check control
panel in the dashboard.This BMW Service and Warranty Information
Booklet should be presented to your BMW
center when maintenance is required. Your
BMW center will stamp this book documenting
the services or maintenance performed.

Maintenance System
The BMW Maintenance System has been
devised with the following objectives: to
maximize vehicle safety, reliability, and resale
value by minimizing breakdowns resulting from
wear, and minimizing cost and inconvenience
by computing maintenance intervals based
upon the specific manner in which each
individual vehicle is driven.
Maintenance intervals on motor vehicles have
conventionally been specified based upon
accumulated mileage. However, the type of
driving conditions has 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, pro-
longed periods of idling, stop-and-go driving,
and high engine speeds during acceleration
requires more frequent 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 service
interval indicator which computes the actual
optimum maintenance requirements based
not only upon the accumulated mileage, but
taking into account important factors such as
engine coolant temperatures, high or low
engine speeds, short or long trip driving, and
number of vehicle starts. The maintenance
interval may therefore be maximized with
considerable savings to owners of vehicles
subjected to light duty.
The Service Interval Indicator consists of a
mileage reading, and the inscriptions “OIL
SERVICE” and “INSPECTION”.
Whenever the ignition is switched on, the
display shows the next scheduled type of
service and the remaining distance until the
service should be performed. The distance is
based on your driving style.If the maintenance interval has been ex-
ceeded, a “—” symbol reminds you of the
urgent need for servicing. In the interests of
road safety and reliability, you should avoid
driving your BMW when the “—” symbol is
showing, and have the essential maintenance
work performed without delay.
After each maintenance is performed the
service indicator is reset in order to compute
the next service interval.
If the Service Interval Indicator displays an
illogical reading, or if there is no display,
consult a BMW center.
If the speedometer, tachometer or coolant
temperature gauge should develop a fault, the
service interval indicator will probably cease to
operate correctly as well, since it depends on
correct speed, distance and temperature
readings. The fault must be located and
rectified by a BMW center.
A detailed list of all maintenance operations
included in each of the elements of the BMW
Maintenance System is found on pages 4-8.
These elements are as follows:
Quality Certification I will be performed by your
selling center and certified on the following
page.
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.

3 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 BMW Z4 models. BMW is evaluating
various synthetic oils for inclusion in our list
of recommended motor oils.
It is recommended to check engine oil level
whenever fuel is added to the vehicle.
– 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 100,000
miles to maximize vehicle fuel economy
and minimize exhaust pollution. 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.
– 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 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
technological advances not only to the design
and production of your vehicle, but also to
computing of the optimum maintenance
interval for your type of operations and driving
style. Your BMW center has made a substantial
investment 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.

(BMW NA) or sold through the BMW NA
European Delivery Program.
In accordance with the defect warranty
provisions of section 207(b) of the Clean Air
Act, BMW NA warrants to the first retail
purchaser, and each subsequent purchaser,
that the car (a) was designed, built and
equipped so as to conform, at the time of sale,
with all regulations of the U.S. Environmental
Protection Agency applicable at the time of
manufacture and (b) is free from defects in
materials and workmanship which would
cause it to fail to conform with applicable
regulations for a period of 2 years or 24,000
miles, whichever occurs first, except for
specific emission control components (as
listed on page 36), for which the warranty
period is 8 years or 80,000 miles, whichever
occurs first.
This warranty begins on the date of first retail
sale, or the date the vehicle is first placed in
service as a demonstrator or company vehicle,
whichever is earlier.
Warranty claims must be made as soon as
reasonably possible after a defect is discov-
ered. To make a claim, the car must be
brought to any authorized BMW center during
normal business hours.
The BMW center will, without charge for parts
or labor (including diagnosis), either repair or
replace the defective part, if any. The decision
whether to repair or replace said parts is solely
the prerogative of BMW NA and must be
expected to correct the failure of the warranted
part. Parts for which replacements are made
become the property of BMW NA. In all cases,
a reasonable time must be allowed for
warranty repairs to be completed after the car

owner may elect to have maintenance, repair
or replacement of the emission control
systems performed by any automotive repair
establishment, or elect to use parts other than
certified 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 or
a warranty replacement part is not reasonably
available (within 30 days), repairs may be
performed at any available service establish-
ment using any equivalent part. BMW NA will
reimburse the owner for such emergency
repairs (including labor, parts and diagnosis
not to exceed BMW NA rates for labor, parts,
and diagnosis in said area) that are covered
under this warranty. Replaced parts and paid
invoices must be presented at a BMW center
as a condition of reimbursement for emer-
gency repairs not performed by a BMW center.
The use of replacement parts, which are not of
equivalent quality, may impair the effective-
ness of the emission control system. If other
than certified BMW Service Parts or Authorized
Remanufactured 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
