Maintenance Program
The BMW Maintenance Program has been
devised with the following objectives: to maxi-
mize vehicle safety, reliability, and resale value by
minimizing breakdowns resulting from wear, and
minimizing cost and inconvenience by comput-
ing maintenance intervals based upon the spe-
cific 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 opti-
mum maintenance requirements based not only
upon the accumulated mileage, but taking into
account important factors such as engine cool-
ant 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 own-
ers of vehicles subjected to light duty.
TheService Interval Indicatorconsists of a
mileage reading, and the inscriptions “OIL SER-
VICE” 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 exceeded, a
“--” symbol reminds you of the urgent need for
servicing. In the interests of road safety and reli-
ability,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 illogi-
cal reading, or if there is no display, consult a
BMW center.
If the speedometer, tachometer or coolant tem-
perature gauge should develop a fault, the ser-
vice interval indicator will probably cease to
operate correctly as well, since it depends on
correct speed, distance and temperature read-
ings. 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 pages4-13.
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 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 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-Perfor-
mance 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 eval-
uating various synthetic oils for inclusion in our
list of recommended motor oils.
BMW recommends that you check engine oil
level whenever fuel is added to your vehicle.

– Inspection I: Major vehicle maintenance as
specified in the following pages under Inspec-
tion I.
– Inspection II: Additional major vehicle mainte-
nance as specified in the following pages under
Inspection II.
The following maintenance elements must be
performed at the mileage/time stated (time inter-
vals 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 to maximize vehicle fuel economy and
minimize exhaust pollution. The replacement of
the oxygen sensor is required under the terms
of the applicable 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 opera-
tions 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 War-
ranty 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 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 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.
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.

Unscheduled Maintenance
Only use fuels advertised to have adequate
detergency and low alcohol content. Use of fuels
with insufficient detergent and/or excess alcohol
can cause driveability problems that necessitate
cleaning intake valves and fuel injection valves,
and, when applicable, adjusting the engine idle.
We suggest having this work performed by your
authorized BMW center, perhaps while regular
maintenance is performed. Your BMW center can
also recommend a gasoline additive that will pro-
vide sufficient detergency. While this recom-
mended unscheduled maintenance is not
required in order to maintain the emission war-
ranty, cleaning of intake valves or, when applica-
ble, fuel injection valves, or adjustment of engine
idle, necessitated by use of inappropriate fuel, is
not covered by warranty because no defect in
material or workmanship or component failure is
involved.
Special Note
Maintenance items and schedules stated herein
reflect the combined recommendations for all
2007 BMW Z4 models and are subject to
change. The most current maintenance recom-
mendations are available from your authorized
BMW center.
