Disc brakes Brake systemDriving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Watch traffic conditions
to ensure that this maneuver does not
endanger other road users. The heat
which is generated by the brake appli-
cations helps to dry the brake pads and
rotors.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique (refer to page 91).
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear requiring minimal
brake applications.
Braking effect on the engine can be
further increased by downshifting, into
first gear, if necessary.If engine braking should prove to be
inadequate, you should still avoid ex-
tended, continuous braking. Instead of
maintaining low to moderate pressure
over an extended period of time, you
should decelerate by applying more
substantial pressure to the brake pedal
(watch for following traffic), releasing
the pedal, and then repeating the appli-
cation (staggered braking). The cooling
phases between active braking inter-
vals prevent the brakes from overheat-
ing and retain full braking capacity.
Do not coast with the clutch de-
pressed, the gear-shift lever in
neutral, or, above all, with the engine
shutt off; otherwise, the engine will pro-
vide no braking effect if the transmis-
sion is in neutral, and there is no brak-
ing or steering power assist if the
engine is not running. Do not allow floor
mats, carpets or any other objects to
protrude into the area around the brake
pedal, the clutch or the accelerator
which could obstruct their freedom of
movement.<
Brake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level is too low in
the reservoir (refer to page 112).
If the brake fluid level is too low
and brake pedal travel has become no-
ticeably longer, there may be a defect
in one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW cen-
ter. Higher brake application pres-
sure may be necessary under these con-
ditions, and brake pedal travel may be
significantly longer. Please remember to
adapt your driving style accordingly.<

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must fall within
the blue zone. If it is not, there is a
danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
2 If the coolant is low, slowly add cool-
ant 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 pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every three years.If the brake warning lamp comes on
and the parking brake has been re-
leased:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for determin-
ing 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 89.
520de093
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 eats away 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 dis-
posal 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 dur-
ing or immediately after exposure to
strong sunlight.
In order to protect your convertible top,
do not have any special waxing pro-
gram done to 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 sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
further damage. In addition, 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.<

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, comply fully with the fol-
lowing instructions during bulb replace-
ment. 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 electri-
cal system, switch off the electri-
cal 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, com-
ply with any instructions provided by
the bulb manufacturer.<
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.<
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, pro-
vided 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.
Because of the extremely high
voltages involved, any work on the
lighting system should be performed
only by authorized technicians. Failure
to comply with this creates a risk of
fatal injury.<
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.

Towing
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingFor instructions on jump starting, refer
to page 143.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1 Put the manual-shift gear lever in
neutral
2 Towing speed:
Max. 45 mph (70 km/h)
3 Towing distance:
Max. 95 miles (150 km)
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers
remain operative, and to prevent the
steering lock detent from engaging
5 Switch on the hazard-warning system
(comply with country-specific regula-
tions).
Find some means of identifying the
vehicle in tow, e. g. place a sign or
warning triangle in the rear window.
Make sure that the ignition key re-
mains in position 1 even when the
electrical system has failed to prevent
the steering lock from engaging. The
steering and brakes are without power
assist when the engine is not running.
This means that increased effort is
required for steering and braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use a wheel lift or flat bed equipment
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to the tie rods, con-
trol arms, or any other part of the vehicle
suspension. If you do so, severe dam-
age will occur to these components.<520us014
