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 opera-
tion in the recirculated-air mode, switch
it off and return the ventilation system
to the incoming air mode; turn up the
blower and select the defroster if
necessary to clear the windows.<
Incoming air mode
Recommended when driving
with the convertible top open.
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 windshield may fog
over briefly when the engine is started.
Do not turn on the air conditioner if the
outside air temperature is below
approx. 41 7 (5 6). This will help to
prevent the windows from fogging.
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
car 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 lockUse one of the master keys. The glove
compartment, the cellular phone holder
and the luggage compartment lid are
now locked.
A master key is also required for
unlocking.
If you turn over only your door and

The cover will open slightly and can
then be flipped all the way up.

Be sure that the flashlight is
switched off when it is inserted
into its holder. Failure to do so could
lead to overcharging and damage.<520de070

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
the vehicle occupants during braking or
evasive maneuvers.
Do not exceed the permissible gross
weight and axle load (refer to page 156),
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
maneuvers and possibly injure vehicle
occupants.<

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 car 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 whenever 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 layer
on a firm base (on gravel or snow, for
instance), the braking distances with
ABS may be longer than with the wheels
locked. This also applies for driving with
snow chains. However, ABS continues
to provide enhanced vehicle stability
and steering response under these
conditions.

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 of 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 opportunity.
Cornering Brake Control (CBC)CBC is an advanced ABS engineering
design. Vehicle stability is also
enhanced when braking during
cornering at a higher rate of lateral
acceleration and during lane changes.
