Indicator lamp flashes:
The system is actively regulating engine
torque and braking force.
If the indicator lamp does not go out
after the engine is started, or if it comes
on during normal driving and stays on:
DSC has been switched off or has been
deactivated because of a malfunction.
In the event of a malfunction, have the
system checked by your BMW center.
For additional information, refer to
page 65.
Service Engine Soon l
If the indicator lamp comes on
either continuosly or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.

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

90n
Dynamic Brake Control (DBC) Disc brakesIf you step on the brake rapidly, this
system automatically produces maxi-
mum braking force boost and thus
helps to achieve the shortest-possible
braking distance during "panic stops."
All of the benfits of the ABS system are
exploited under these circumstances.
Do not reduce the pressure on the
brake pedal during the brake applica-
tion. When the brake pedal is released,
the DBC is deactivated.
In the event of a malfunction,
the yellow brake warning lamp
comes on. Normal braking effi-
ciency and ABS are still fully
available. Have the system
checked and repaired at your
BMW center as soon as possible.
For your safetyNot even DBC 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 DBC to
mislead you into taking risks of any
kind.Disc brakes furnish optimal decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, or in oper-
ating conditions where brake applica-
tions are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the disc brakes by brake applications is
not achieved.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads BMW has approved
for your specific vehicle model. BMW
cannot evaluate non-approved brake
pads to determine if they are suited for
use, and therefore cannot ensure the
operating safety of the vehicle if they
are installed.<

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.<

Brake system Winter operationBrake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level in the
reservoir is too low, refer to
page 114.
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum thickness. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Winter is often accompanied by rapid
changes in weather, requiring not only a
different driving style, but also certain
preparations to the vehicle itself to
ensure that your progress through the
winter months remains safe and
trouble-free. CoolantBe sure that the coolant mixture
contains the year-round ratio of 50:50
water and extended-duty antifreeze
with corrosion inhibitor. This mixture
provides protection against freezing
down to approx. Ð34 7 (Ð37 6).LocksBMW door lock deicer can be used to
free doors if frozen. This deicer also
contains lubricant.
After using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.

Winter operation Power steering Cellular phone Skid control Depress the clutch and release the
accelerator pedal. Countersteer care-
fully and attempt to regain control over
the vehicle.ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. In order
to prevent the parking brake pads from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not come
on when the parking brake is
engaged.<
If there is a change in steering response
Ð e. g. difficult or over-responsive
steering Ð at increasing speeds, consult
a BMW center to have it checked.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
Mobile communications systems
(cellular phone, radio, etc.) are
permitted with an output of up to
10 watts only. Mobile communications
devices not specifically designed for
use in your vehicle may trigger malfunc-
tions while you are operating your
vehicle. BMW can neither test nor
assume responsibility for every indi-
vidual product being offered on the
market. We recommend that you
consult your BMW center before
purchasing any device of this kind.
To ensure reliable and trouble-free
operation of your BMW, do not use any
cellular phones or other radio devices
where the antenna is located either
inside the passenger compartment or
otherwise not attached to the outside of
the vehicle.
You will find instructions for operating
your cellular phone in the supplemen-
tary Owner's Manual.
