coolant level BMW Z4 COUPE 2008 E86 Service and warranty information

Special Note
Maintenance items and schedules stated herein
reflect the combined recommendations for all
2008 BMW Z4 models and are subject to
change. The most current maintenance recom-
mendations 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.
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 evaluating 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
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
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 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.
