2008 BMW Z4 M COUPE engine coolant

Vehicles used in competitive events
 Oil changes performed outside the recom-
mended maintenance intervals as indicated
by the Service Interval Indicator
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 Indicator lights on the check control
panel in the dashboard.
Maintenance intervals on motor vehicles have
conventionally been specified based upon accu-
mulated 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, prolonged periods of
idling, stop-and-go driving, and high engine
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 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 sav-
ings to owners of vehicles subjected to light
duty.
This BMW Service and Warranty Information
Booklet should be presented to your BMW cen-
ter when maintenance is required. Your BMW
center will stamp this book documenting the
services or maintenance performed.
Maintenance Program
The Service Interval Indicator consists of a
mileage reading, and the inscriptions “OIL SER-
VICE” and “INSPECTION”.
Whenever the ignition is switched on, the dis-
play 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
reliability, you should avoid driving your BMW
when the “--” symbol is showing, and have
the essential maintenance work performed with-
out delay.
After each maintenance is performed the ser-
vice 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 Program is found on page s4-9.
These elements are as follows:
Quality Certification I will be performed by your
selling center and certified on page 4.

Special Note
Maintenance items and schedules stated herein
reflect the combined recommendations for all
2008 Z4 M Coupe and Roadster models are
subject to change. The most current mainte-
nance 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 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 the only approved
engine oils are: Castrol TWS Motorsport SAE
10W-60 Synthetic, or Castrol Formula RS
10W-60 Synthetic (BMW part number
07 51 0 009 420).
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
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 to maximize vehicle fuel econ-
omy and minimize exhaust pollution. The
replacement of the oxygen sensor is required
under the terms of the applicable BMW emis-
sion system warranties. 
Spark Plug Service: Replace spark plugs at
every Inspection II.
 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
operations to fulfill any state inspection require-
ments in your area concurrent with the mainte-
nance elements specified above during other
repairs. Should you request more frequent
maintenance service, the cost of these ser-
vices will not be covered by the Maintenance
Program.
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.
