Engine oilChecking the oil level 1. Park the vehicle on a level surface
2. Let the warmed-up engine idle for
about 15 seconds, then turn it off
3. Pull the dipstick out after about
1 minute and wipe it off with a clean
lint-free cloth, tissue, or similar mate-
rial
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.520de089
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.520de091
Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
this mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, differential and
the power steering system.<520de166

Engine oil Specified engine oilThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain types of engine oils.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Use only oils with
API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" that have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com for more
detailed information.
Viscosity ratings Viscosity is the oilflow rating as estab-
lished in SAE classes.
Select the correct SAE class based on
the climatic conditions in the area
where you typically drive your BMW Z8
roadster.
Approved oils are SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing.
For this reason, thoroughly wash any
areas of skin that come into contact
with oil using soap and water.
Always store oils, grease, etc. so that
they are inaccessible to children, and
follow warning lables on containers.<
Do not add coolant to the coolant
system when the engine is hot,
since escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite- and amino-
free, extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and corrosion inhibitor is
hazardous to health. Always store in
tightly closed original containers kept
well out of the reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol: never allow
the antifreeze to spill onto hot engine
components, as fire and serious
personal injury in the form of burns
could result.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
Checking coolant levelThe correct coolant level when the
engine is cold (approx. 687/206):
Up to the "MAX" mark on the translu-
cent expansion tank.520de156

Coolant Brake fluidAdding coolant To guard against the possibility of
scalding injuries, always wait until the
engine cools (temperature gauge
needle in blue sector) before
unscrewing the cap on the expansion
tank.
1. Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
2. Slowly add coolant until the correct
level is reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every three years.The brake warning lamp comes on and
the parking brake has been released:
The brake fluid is too low.
For adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss can increase brake
pedal travel. For this type of situation,
refer to the notes on page 92.
520de157
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet
(US models) or the Warranty and
Service Guide Booklet (Canadian
models). Brake fluid is toxic and attacks
the vehicle's paintwork. You should
always store it in its original container
and in a location that is inaccessible to
children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<

The BMW Maintenance System has
been designed as a reliable means of
ensuring that our customers enjoy
optimal vehicle safety and reliability
with only minimum effort and expense.
Please keep in mind that regular service
not only plays a vital role in ensuring
continued vehicle safety, but also plays
a significant role in maintaining your
vehicle's resale value.

Service Interval DisplayOptimal maintenance intervals are
calculated by using advanced tech-
nology; these then are indicated in the
Service Interval Display. While conven-
tional systems rely on distance traveled
alone to determine when service is due,
the BMW Maintenance System has for
years considered the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the maintenance point of view,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
equivalent to the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System, which
is based on operating conditions,
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those drivers
who put significantly less than
6,000 miles (10,000 km) on their vehicle
anually should have the engine oil
changed at least every two years since
oil deteriorates over time, regardless of
use.

Have your BMW center perform
maintenance and repair work.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the
required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
These entries are your proof of regular
vehicle maintenance and the basis for

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5. Fill the fuel tank completely to
prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1. Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).

Technical modifications California Proposition 65 WarningAny BMW center will be happy to
advise you concerning the advisability,
legal requirements and factory recom-
mendations for technical modifications
to the vehicle. The BMW center will
require the Vehicle Identification
Number and, in some cases, the engine
number as well. Light-Emitting Diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. These light-
emitting diodes are similar to conven-
tional lasers.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours). To do so could result in
inflammation of the iris.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<
