Dynamic Stability Control (DSC) Dynamic Performance To reactivate the systemPress the button again; the indicator
lamp goes out.
Not even DSC can suspend the
laws of physics. Responsibility for
careless driving remains in the hands
(and feet) of the driver. Never use the
added safety provided by DSC as an
excuse for taking unnecessary risks.
Do not make any modifications to the
DSC system. Service procedures on
the system are to be performed by
authorized technicians only.<
For additional information concerning
DSC, please refer to the chapter
"Advanced technology" on page 151.
The system reacts to current conditions
with an instantaneous recalibration. It
revises the accelerator's standard
response designed to furnish an ideal
combination of comfort and perfor-
mance orientation Ð with a more perfor-
mance-oriented response program. The
result is crisper, faster reaction to
throttle inputs (Sport mode).
The system resets to the standard
response mode, with its combination of
comfort and performance orientation,
each time the engine is restarted. 520de057

Parking lamps (side marker
lamps)
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
When leaving the vehicle parked, you
also have the additional option of acti-
vating the lighting on just one side, refer
to page 70.
Low beams
If you switch off the ignition
while the low beams are on,
only the parking lamps (side
marker lamps) remain on.
520de036
"Follow me home" lamps:
If you actuate the headlamp
flasher after you have parked the
vehicle and shut off the engine, the low
beams will remain on for a brief period.
You may also have this function deacti-
vated if you wish.<
"LIGHTS ON" warningIf you turn the ignition key to position 0,
an acoustic signal will sound for a few
seconds after the driver's door has
been opened if the low beams have not
been switched off.Daytime driving lamps

Heating and ventilation/Air conditionerAir supply
You can select blower speeds
from 1 to 4. The higher the
setting, the greater the
amount of heat and air supply.
In position 0, the blower, heating and
air conditioner are switched off.
Temperature
In order to increase the inte-
rior temperature, turn to the
right. For rapid heating, turn
completely to the right. Then
select an interior temperature that is
comfortable for you.
Air distribution
You can direct the airflow onto
the windows , toward the
upper body and into the
footwell . You can also
make all intermediate settings. The
"6 o'clock" setting is recommended for
normal conditions (refer also to the
illustration and overview on page 72).
Recirculated-air mode
If there are unpleasant odors
in the incoming air, you can
temporarily block the air
supply. The system then recir-
culates the air already within the
vehicle.
If condensation starts to form on
window surfaces during operation
in the recirculated-air mode, switch this
mode off and increase the air supply as
required, or press the button for
"Defrosting windows and removing
condensation".<
Incoming-air mode
Recommended when driving
with the convertible top down.
The degree to which the
passenger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/Incoming-air
mode
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(5 6). This will
help to prevent condensation from
forming on window surfaces.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Air conditioner/Recirculated-air
mode
You may find it useful to acti-
vate both systems to cool the
vehicle more rapidly after it
has been parked with the top
up on a hot day. This setting provides
the coldest possible airflow from the
vent outlets (with temperature selection
switch turned all the way to the left).

To ensure that your vehicle provides
maximum economy throughout an
extended service life, we request that
you comply with the following informa-
tion.
Your BMW Z8 is an especially
high-quality vehicle. To protect
your own investment, we recommend
that you follow he break-in instructions
carefully. By doing so, you will create
the basis for optimal service life of the
vehicle.<
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine and road
speeds, but do not exceed 4,500 rpm
or a road speed of 106 mph (170 km/h).
Comply with local and state maximum
speed limits.
Avoid depressing the accelerator to the
full-throttle position.
Following the Break-In Inspection at
1,200 miles (2,000 km), you can gradu-
ally increase engine or road speeds.
You should also comply with these
break-in procedures if the engine or
differential is replaced later in the
course of the vehicle's service life.TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles (300 km).
Comply with local and state maximum
speed limits.
When the vehicle is being driven
on wet or slushy roads, a wedge
of water may form between the tire and
the road surface. This phenomenon is
referred to as "aquaplaning" and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
Brake systemApproximately 300 miles (500 km) must
elapse before the brake pads and
rotors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and long service life.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come
on when the parking brake is
engaged.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine shut off Ð when
towing, for instance Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). Engage the gears carefully
and without high engine speeds during
this break-in period.
Break-in procedures

87n
IndexDataTechnologyRepairsCar careControlsOverview
Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but
consistent pressure on the brake pedal
could lead to high temperatures, brake
wear, and possibly, to brake system
failure.
Aquaplaning:
Reduce speed while driving on wet or
slushy roads, otherwise, a wedge of
water can form between the tires and
the road surface. This phenomenon is
referred to as "aquaplaning" or "hydro-
planing." It is characterized by a partial
or complete loss of contact between
the tires and the road surface. The ulti-
mate results are loss of steering and
braking control.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm), and even then, only at walking
speed, otherwise the vehicle can
sustain damage to the engine, the elec-
trical systems and the transmission.<
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system's oxygen sensor.
To ensure efficient, trouble-free engine
operation and to avoid potential
damage:
>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel could ignite on the way to the
catalytic converter and cause
damage. It is better to start the
vehicle with a battery charger or
assistance from another vehicle
>Avoid other situations where the fuel
is either not burned or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, there is the
danger of overheating and damage to
the catalytic converter.
Extreme temperatures are present with
the catalytic converter both on this and
every catalyst-equipped vehicle. Heat
shields are installed adjacent to some
sections of the exhaust system. Never
remove these shields; do not apply
undercoating to their surfaces. When
driving, standing at idle, and parking
the vehicle, take care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves
etc.). Such contact could start a fire,
resulting in serious personal injury and
property damage.<

Antilock Brake System (ABS)Information for your safetyNot even ABS can suspend the laws of
physics. The consequences of brake
applications with inadequate clear-
ances for safety between vehicles,
excessive speed or if aquaplaning
occurs are always the responsibility of
the driver. You should never allow the
added safety provided by ABS to
mislead you into taking risks of any
kind.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
In case of a system malfunction
If the ABS warning lamp comes
on, refer to page 21. The brake
system will then function the
same as on vehicles without
ABS. However, have the brake
system checked by your BMW
center as soon as possible. To prevent
undetected defects and cumulative
faults from adversely affecting the
brake system, refer any problems to
your BMW center at the earliest oppor-
tunity.
Cornering Brake Control (CBC)CBC is an advanced ABS engineering
design. Vehicle stability is also
enhanced when braking during
cornering at high rates of lateral accel-
eration and during lane changes.

Disc brakesDriving notesWhen driving in heavy rain and on wet
roads it is advisable to apply light pres-
sure to the brake pedal every few miles.
Monitor traffic conditions to ensure that
this maneuver does not pose a hazard
to you or to other road users. The heat
generated in this braking process helps
dry the 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 93).
When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
You can enhance the engine's braking
effect by downshifting, into first gear, if
necessary. Even if engine braking fails to slow the
vehicle sufficiently, you should still
make every effort to avoid prolonged
braking with continuous application of
low to moderate pressure at the pedal.
It is better to decelerate the vehicle by
applying a higher level of force at the
pedal (watch following traffic!) and then
subsequently pausing to allow the
brakes to cool briefly before starting on
your next braking cycle. By protecting
brake system components against
overheating, the cooling phases
afforded by this staggered, or intermit-
tent braking technique help maintain
consistent availability of optimal braking
response when it is needed.
Do not coast with the clutch pedal
depressed, the gear-shift lever in
neutral, or, above all, with the engine
off; otherwise, the engine will provide
no braking effect if the transmission is
in neutral, and there is no braking or
steering power assist if the engine is
not running. Never allow floor mats,
carpets or any other objects to obstruct
the accelerator, clutch or brake pedals
and pose a safety hazard by reducing
their available travel range.<

Winter operationRubber seals and componentsTo prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car-care products is
available from your BMW center. * only in pairs
on rear tires, complying with the manu-
facturer's safety precautions. Do not
exceed a maximum speed of 30 mph
(50 km/h) while the snow chains are
mounted and refrain from activating the
Flat Tire Monitor, as the snow chains
could trigger false alarms and/or
prevent the system from detecting
actual pressure loss.
Starting off When starting off in deep snow or when
"rocking" the vehicle to free it, it may be
advisable to temporarily deactivate the
DSC. Refer to page 65.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
Driving on low-traction road
surfaces Do not activate the Sport mode (refer to
page 66). Use smooth, gentle pressure
to control the accelerator pedal. Avoid
excessive engine speeds and upshift
early. Downshift well in advance when
approaching uphill or downhill grades.
Maintain an adequate distance
between yourself and the vehicle
ahead. BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking
distance are considerable and should
be kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response. If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking.
Then increase the pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
You can always then attempt to steer
around hazards after you have reduced
pressure on the brake pedal.
Never downshift to exploit engine
braking when driving on slippery
road surfaces, as this could lead to a
loss of traction at the rear wheels,
impairing your ability to control the
vehicle.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<
