Cargo loadingStowing cargo If you are carrying cargo in the luggage
compartment of your BMW Z8 roadster:
>Load heavy cargo as far forward as
possible, directly behind the luggage
compartment partition
>Cover sharp edges and corners.
If you are stowing cargo behind the
seats in your BMW Z8 roadster:
>Stow only lightweight objects, such
as clothing
>Do not pile objects higher than the
top edge of the backrest.
Do not stow either heavy cargo or
cargo with sharp edges and
corners behind the seats, or else they
could damage the back of the seat or
the rear trim panel.
Cargo that is too big or unwieldy and
stowed behind the seats can also
prevent the seat from locking properly
into position. Therefore, check to make
sure that the seat is properly locked
into place, moving the seat forward if
necessary. Refer to page 45.
Always position and secure the load
correctly. If you do not, it can endanger
vehicle occupants during braking or
evasive maneuvers.
Do not exceed the approved gross
weight or the approved axle loads (refer
to page 160), otherwise the vehicle's
operating safety is no longer assured
and you are in violation of the law.
Make sure to secure heavy or hard
objects you stow in the passenger area,
otherwise, these objects could be flung
about during braking or evasive maneu-
vers and possibly injure vehicle occu-
pants.<

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)The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. Why is this important?
When front wheels lock up and cease
to turn, the tires break into a slide.
Result: the driver loses the ability to
steer the vehicle. Traction loss at the
rear wheels can cause the back end of
the vehicle to slip sideways and break
away in uncontrolled oversteer.
With ABS, you will achieve the shortest-
possible braking distances under all
given conditions (braking while driving
straight ahead or in curves, different
road surfaces).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help retain steering and maneu-
vering capability on all types of road
surfaces (asphalt, concrete, dirt, wet
surfaces, snow and ice).
Braking with ABSThe system is operative once the
vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is deacti-
vated whenver the vehicle's speed
drops back below approx. 4 mph
(6 km/h). This means that the wheels
can lock only in the final phase of a
panic stop Ð a factor of no substantive
significance in actual use.
The ABS system works best in situa-
tions requiring maximum pressure on
the pedal (full braking). Since the
vehicle maintains steering responsive-
ness, you can nevertheless avoid
possible obstacles with a minimum of
steering effort.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
A pulsing of the brake pedal, combined
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you
should adapt your vehicle's speed to
road conditions. On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel, deep sand or snow,
for example), braking distances may be
longer than with locked wheels. This
also applies to driving with snow
chains. However, ABS continues to
provide enhanced vehicle stability and
steering response under these condi-
tions.

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.

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.<

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.<

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.

Information for your safetyThe vehicle's factory-approved safety
tires have been specially designed to
provide optimum safety and driving
comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a
frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW. Check tire
inflation pressures regularly (refer to
page 26), at least every two weeks and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Safety tiresYour BMW Z8 is equipped with safety
tires.
The assembly consists of self-
supporting tires mounted on specially-
designed wheel rims. Special reinforce-
ment elements support the sidewalls in
the event of pressure loss. Although tire
performance is then restricted, the
vehicle can still be driven on the
deflated tire for a limited distance. Your
vehicle is equipped with a Flat Tire
Monitor that signals you in case of a flat
tire.
For further information, refer to
pages 67, 137.
Tire tread Ð tire damageInspect your tires frequently for tread
depth, wear, signs of damage and for
foreign objects lodged in the tread.
Tread depth should not be allowed to
fall below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At at
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base will indicate that the legally
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.390de331
