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 continue
turning to remove.
2 If the coolant is low, 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:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
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 91.
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.<

Washing your vehicle You can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes
are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the vehicle.
In order to avoid spots, do not wash the
vehicle when the hood is warm, or
during or immediately after exposure to
strong sunlight.
In order to protect your convertible top,
do not use washing programs featuring
wax application on your vehicle. The
small amount of beading wax always
used in automatic car washes will not
harm the convertible top.
When using an automatic car wash, be
sure that
>the car wash system is suited for the
dimensions of your vehicle
>no damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary >the wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>the vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.
Parts of the vehicle which are inacces-
sible to the automatic washer Ð such as
door sills, door and hood edges, etc. Ð
should be cleaned by hand.
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Large quan-
tities of dirt and road salt are difficult to
remove, and they also cause damage to
the vehicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's
surface. Inadequate distance and
excessive pressure can damage or
weaken the finish, making it more
susceptible to further damage. In addi-
tion, moisture could penetrate to
vehicle components, leading to long-
term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth. Never use abrasives or strong
solvents to clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
rotors could also be corroded.<
Caring for your vehicle

Caring for your vehicleCleaning and care of the
convertible topThe appearance and life of the convert-
ible top are highly dependent on its
proper care and operation. You should
pay particular attention to the following
instructions if your vehicle has a light-
colored top.
Protect the vehicle from exposure to
intense sunlight whenever possible by
parking it in the shade. This will help
to prevent the paint, rubber and fabric-
covered parts from being attacked.
Never fold up the convertible top and
store it in the convertible top compart-
ment when it is wet, dirty or frozen, as
mildew stains and chafe spots may
result.
To prevent the formation of a crease
in the rear window and to avoid mildew
stains, do not leave the top folded in the
convertible top compartment for long
periods.
If the vehicle will be parked for lengthy
periods in an enclosed space, be sure
that the convertible top is dry and that
there is adequate ventilation.Clean off bird droppings immediately,
since they attack the convertible top
and cause the rubber seals to swell due
to their caustic characteristics.
Besides water, treat rubber seals only
with talcum powder, rubber care prod-
ucts or silicone spray, particularly when
they feel dry or tend to stick.
Eliminate noises such as squeaks with
lubricant spray.
Never use sharp-edged objects to
clean the rear window of snow or ice.
If using a deicer spray, make sure that
none of the spray comes into contact
with the convertible top. Because of the
risk of damage and discoloration, do
not apply adhesive tape, stickers, or
similar materials to the window or cover
with plastic film. Dents and discoloration may show up
on the convertible top because of
improper care, cleaning or as the result
of excessive usage. The convertible top
and its seams may also develop leaks.
These problems are not covered by the
warranty. For repairs, please consult
your BMW center.
Special wash for the topRespond to more extensive dirt, which
is especially visible on light-colored top
materials, by cleaning the top with the
BMW Convertible Cleaning Set. Please
proceed as follows:
Spray the convertible top with the
cleaning agent and then rub with a well-
dampened sponge using circular
motions until a foam develops. Then
you can finish washing the vehicle in an
automatic car wash. After three to five
washings the convertible top should be
treated with a special impregnating
spray. Please follow the instructions on
the spray can.

Caring for your vehicle
To remove stains from the
convertible top, use only BMW-
approved cleaning agents. Do not use
spot removers, paint thinners, solvents,
gasoline or similar substances for
removing stains; these agents destroy
the rubber seals, which in turn leads to
leaks.
A full range of car-care products is
available from your BMW center.<
HardtopPlease observe and follow the instruc-
tions for caring for your vehicle starting
on page 115.
Exterior finish Your vehicle is protected by a multilayer
finish applied at the factory. Protection
against corrosion is provided by
cataphoretic immersion priming using
materials that have been specially
developed over many years of
sustained research.
Regular maintenance makes an impor-
tant contribution to maintaining the
safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
programs designed to further improve
the durability of their finishes. Despite
this, environmental factors that occur
locally or regionally can have negative
effects on the finish of your vehicle.
These should guide you in determining
the frequency and extent of your efforts
to maintain the vehicle finish.Road dirt, tar spots, dead insects,
animal droppings (strong alkali effect)
and even tree secretions (resins and
pollen), all contain substances capable
of causing damage to the finish of your
vehicle if allowed to remain for an
extended period of time (such as stains,
bumps, scratches and separation of the
top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
vehicle's finish unless adequate care is
provided Ð even though this is generally
limited to the outside horizontal
surfaces.
In tropical climates intense ultraviolet
radiation and high atmospheric
humidity are accompanied by tempera-
tures that can exceed 105 7 (40 6) in
the shade. Under those conditions, light
paints can reach temperatures of up
to 175 7 (80 6) while darker finishes
can heat to levels as high as 250 7
(120 6).

Caring for your vehicleWindow careYou can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
Clean the wiper blades with soapy
water. The wiper blades should be
replaced twice a year Ð before and after
the cold season.
Use only wiper blades approved
by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products containing
acids, strong alkalis or abrasives. Do
not use steam cleaners operating at
temperatures above 140 7 (60 6).
Follow the manufacturer's instructions.
Carefully clean chrome parts such as
lamp socket assemblies, door handles
and similar items with an ample amount
of clean water Ð and shampoo, too, if
necessary Ð especially if there is an
accumulation of road salt. Use a
chrome polish for an additional treat-
ment.
Use water to clean plastic components,
headliners, lamp lenses, and surfaces
sprayed dull black Ð adding vinyl
shampoo, if necessary. Do not allow
moisture to soak through the seats or
headliner. Never use solvents such as
lacquer thinner, heavy-duty grease
remover, fuels, or similar substances.
Use a soft, clean cloth to wipe off the
clear covers of the instruments, using
methylated spirits with distilled water
as a cleaning solvent, if necessary, at a
mixing ratio of 1:1.Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts
prevent the inertia reel mechanism from
retracting the strap properly, thus
constituting a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Clean the aluminum surfaces with water
and, if necessary, with a mild soap.
Never use solvents such as lacquer
thinner, heavy-duty grease remover,
fuels, or similar substances.
Use only a wet cloth to clean the painted
inner parts. Dry them afterwards with a
soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<

Caring for your vehicleLeather care The leather upholstery used by BMW is
a natural product of the highest quality,
processed using state-of-the-art
methods to ensure that it will maintain
its high quality for years to come,
provided that it is properly cared for.
Because the leather upholstery is
crafted using unadulterated natural
materials, it will display individual char-
acteristics and possible surface irregu-
larities. You should also bear in mind
that this kind of material needs special
care and attention.
Regular periodic cleaning and care are
essential, as dust and road dirt act as
abrasives in the pores and creases of
the material. This leads to wear spots
and premature brittleness on the
surface of the leather. We therefore
suggest that you clean the leather with
a vacuum cleaner or cloth at frequent
intervals.
For cleaning, use BMW leather cleaning
foam.Since dirt and grease gradually attack
the protective layer of the leather, the
cleaned surfaces should be treated
with BMW leather care agent. This also
prevents static electricity.
For protection against dampness or
moisture, treat the leather with a BMW
impregnating agent.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery is to be exposed to
intense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the
windows) to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<
Cleaning agents can contain
dangerous or health-threatening
substances. Therefore, always comply
with the warnings and danger notices
on the package.
Open the doors or windows on your
vehicle when cleaning the interior
(when the convertible top is closed).
Never clean your vehicle with solvents
or other materials not specifically
intended for this application.<

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.<

OBD interface socket The OBD interface socket for onboard
diagnostics is located on the driver's
side at the left-hand bottom of the in-
strument panel and under a cover panel.
The cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system throughout the
vehicle's lifetime by monitoring emis-
sion-related components and systems
for deterioration and malfunction.520de130
An illuminated indicator informs
you of the need for service, but
not of the need to stop the
vehicle. However, the systems should
be checked by your BMW center at the
earliest possible opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates severe
engine misfire. When this occurs, you
should reduce speed and consult the
nearest BMW center as soon as possi-
ble. Severe engine misfire over only a
short period of time can seriously dam-
age emission control components, es-
pecially the catalytic converter.
Service Engine Soon warning

When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.<

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the elec-
trical system, switch off the elec-
trical accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
When cleaning the headlamps,
please observe the following:
>Do not wipe dry (scratches). Never
use abrasives or strong solvents to
clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
Xenon lamps

The main headlamps for your BMW
Z8 roadster have been designed using
xenon-light technology. The service life
of these bulbs is very long and the
probability of a failure is very low,
provided that they are not switched on
and off an unusual number of times.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.
The xenon light unit operates at
extremely high voltages; contact
with the unit's electrical components
can be fatal. We therefore urge you to
refer all service and repairs, including
bulb changes, to qualified professional
technicians.<
Neon lampsThe front turn signal indicators (side
marker lamps), the rear turn signal indi-
cators, the rear and brake lamps, as
well as the high-mount brake lamp, are
of neon-light technology. The service
life for these lamps is very high and the
likelihood of failure very minimal.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.

Battery
A highly explosive gas is
generated when the battery is
charged.
If you happen to get acid in
your eyes, rinse thoroughly for
some minutes with clear water.
Consult a physician immediately. If you
get acid spray on your skin or clothing,
rinse with plenty of water. If acid is acci-
dentally ingested, consult a physician
immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Removing and installing
Do not disconnect the battery
cable when the engine is running.
Disconnecting the battery cable when
the engine is running will cause a
voltage surge which will damage the
vehicle's onboard electronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repairs and disposal may only be
performed by specially trained
personnel.<
When removing, first disconnect the
cable to the negative terminal, then
disconnect the cable to the positive
terminal. Loosen the center adjusting
screw for the battery's retaining strap
(use the screwdriver found in the
onboard tool kit) and remove the
bracket.
When installing, first connect the cable
for the positive terminal, then the cable
for the negative terminal.
When installing, make sure that
the battery is seated properly, and
that the battery bracket is installed with
the center adjusting screw. Failure to
observe these precautions could result
in an inadequately secured battery,
which could then shift in an accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump starting" on page 143).
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle's electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the
battery, charge it and store it in a cool
and dust-free room where there is no
danger of freezing. During storage,
have the battery recharged every six
months. Also, recharge the battery
before it is reinstalled. Failure to
observe these precautions can render
the battery unsuitable for continued
use. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.
