Electronic vehicle immobilizer The key to securityThe electronic vehicle immobilizer
reduces your BMW's susceptibility to
theft by rendering it impossible to start
the engine using any means other than
the car's own individual keys. The
system operates automatically, with no
action or intervention on your part. Your
BMW center can cancel the system
authorization for individual keys (for
instance, if a key is lost). A deactivated
key can no longer be used to start the
engine.520de146
Advanced electronics in actionAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will release the ignition, elec-
trical steering lock, fuel injection and
starter for use only if it detects an
"authorized" key.
Exposure to external force can
damage the key's integrated elec-
tronic circuitry and render it inoperative.
A damaged key can no longer be used
to start the engine or release the
steering lock.<

The automatic convertible topWeather protectionThe fabric convertible top combines
reliable protection from the elements
with simple, convenient operation. Here
are a few tips to ensure that you enjoy
your BMW Z8 roadster.
It is advisable to close the convertible
top when the vehicle is parked. The
closed convertible top not only protects
the passenger compartment from
unforeseeable damage from the
weather, it also provides a certain
degree of theft protection. Even if the
convertible top is closed, store your
valuables only in the locked luggage
compartment.
To prevent damage to its rear window,
avoid opening or closing the fabric top
unless the temperature is well above
freezing. Operate the convertible top only
when the vehicle is stationary,
otherwise the procedure will be inter-
rupted. Driving before the opening or
closing procedure has been properly
concluded can lead to damage or
injury.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Make sure that no objects or people get
in the way while the convertible top is
opening or closing, so that no damage
or injuries occur.
The automatic operating procedure is
interrupted immediately if the switch
for actuating the top is released. The
procedure can be continued in the
desired direction by pressing this
switch.<
To openFrom ignition key position 1:
If at all possible, only operate the
convertible top if the engine is running
to avoid discharging the battery.
Press and hold the switch in the
"Open" (1) direction until the opening
procedure has been completed with the
convertible top being stored in the
convertible top compartment and the
indicator lamp on the instrument cluster
(refer to page 18) has gone out.
The side windows will lower slightly
when the convertible top is being
opened. To reclose the side windows,
maintain pressure on the switch after
the indicator lamp goes out. 520de055

Starting the engine Before starting>Engage the parking brake
>Make sure that the transmission is in
neutral
>Depress the clutch pedal
>Turn ignition key to position 2.
Do not allow the engine to run in
enclosed areas. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<520de141
Do not press the accelerator pedal
while starting the engine (pressing the
starter button).
Do not actuate the starter button
for too short a time, but do not
keep it pressed for more than approx.
20 seconds.<
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.
Cold starts at very low temperatures,
from approx. +5 7 (Ð15 6) and at alti-
tudes above 3,300 ft (1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
Engine idle speed is controlled by the
electronic engine-management system.
A fast idle immediately after starting is
normal and should decrease as the
engine warms up. If the idle does not
return to normal as the engine reaches
normal operating temperature, service
is required.
To prevent the battery from
discharging, always deactivate elec-
trical devices that are not in use. Switch
the ignition off when the vehicle is not
being driven.

Switching off the engine Parking brake Turn ignition key to position 1 or 0.
Never remove the ignition key
while the vehicle is rolling. If you
do so, the ignition lock would engage
when the steering wheel is turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Always engage the parking brake when
parking on hills and inclined surfaces,
as first gear or reverse may not provide
adequate resistance to rolling.<
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels. To engage The lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument cluster comes on
when the ignition key is in position 2.
Refer to page 21.To releasePull up slightly on the lever, press the
button and lower the lever. 520de024
If, in rare circumstances, it should
be necessary to engage the
parking brake while the vehicle is in
motion, do not pull hard on the lever.
Keep your thumb pressed against the
release button while carefully pulling
the lever up to apply moderate pres-
sure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on hills and inclined surfaces,
as selecting first gear or reverse may
not provide adequate resistance to
rolling.<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.

Manual transmission Indicator/Headlamp ßasher Every time you shift gears, always
depress the clutch pedal all the way
down, pushing the gear lever into the
desired position.
Always remember to depress the clutch
pedal when starting the engine; a lock-
out device prevents starting when the
clutch is engaged.
The shift lever's neutral plane is located
between 3rd and 4th gears.
The shift lever automatically returns to
the 3rd/4th plane whenever you select
neutral. 520de158
When shifting across the gate to
the 5th/6th gear plane always
remember to push the lever to the right
to avoid inadvertent engagement of 3rd
or 4th gear.<
Reverse Select only when the vehicle is
stationary. Press the shift lever to the
left to overcome the resistance.
As you do this, the backup lamp will
turn on automatically when the ignition
key is in position 2.
Never slip the clutch to prevent
the vehicle from rolling backwards
when stopping on hills. Slipping the
clutch for extended periods leads to
rapid, premature clutch wear.<

lamp and cyclical clicking from the
blinker relay)
If the indicator lamp and the clicking
from the relay are faster than normal,
one of the turn signal bulbs is defective. To signal brieflyPress the lever up to but not beyond
the pressure point. It then returns to the
center position when released. 520de025

Cruise controlYou can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
Refrain from using the cruise
control on twisting roads, when
high traffic density prevents driving at a
constant speed, and when driving on
slippery (snow, rain, ice) or loose
(gravel, sand) road surfaces.<520de061
Store and maintain
speed/acceleratePress the lever briefly in direction 1:
The system maintains the current
vehicle speed. Every time you briefly
press the lever, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold the lever in position 1:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the lever, the system main-
tains the current speed.
The vehicle may accelerate
beyond the preselected speed on
steep downhill stretches, where engine
braking alone may not be enough to
slow the vehicle. It can also slow when
the engine fails to maintain the prese-
lected speed when ascending steep
grades.< To decelerate Press the lever briefly in direction 2:
With the cruise control active, the
speed decreases by approx. 0.6 mph
(1 km/h) every time you briefly touch the
lever.
Press and hold the lever in position 2:
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the lever, the system
registers and maintains the current
speed. To cancel the cruise controlPress the lever briefly in direction 3:
The cruise control is immediately
canceled.
In addition, the system automatically
deactivates in response to the following
conditions:
>braking
>clutch disengagement
>when vehicle speed deviates from
the preset speed for an extended
period, for instance, as a result of
pressure on the accelerator pedal. To deactivate the system Turn ignition key to position 0.

1 Odometer With the ignition key in position 0, you
can activate the displays shown in the
illustration by pressing the button in the
instrument cluster (arrow).2 Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 and up.520us004
Never allow engine speed to climb until
the needle enters the tachometer's red
sector.
To protect the engine, the engine-
management system automatically
interrupts the fuel supply in this range,
producing the sensation of a sudden
loss of power.520de029
When you switch on the ignition, the
indicator lamp lights up briefly to
confirm that the system is operational.
Once the indicator lamp comes on and
stays on, there are approx. 2.5 gallons
(10 liters) of fuel left in the fuel tank.
For fuel tank capacity, refer to
page 161.
Certain operating conditions (such
as those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result
in damage to the engine or catalytic
converter.<520us005

Coolant temperature gauge Service Interval Display BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on in the course of
normal vehicle operation, the engine
has overheated. Turn it off immediately
and let it cool down.520de031
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response
to high outside temperatures or severe
operating conditions.
For checking coolant level, refer to
page 113.
Remaining distance before
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The remaining distance in miles and the
next scheduled service will appear
together with the display OILSERVICE
or INSPECTION.
The computer bases its calculations for
the remaining distance on the previous
driving style.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of miles displayed.
Please contact your BMW center for an
appointment.520us006

The conceptDSC maintains vehicle stability even in
critical driving situations.
DSC maintains optimal, predictable
response while maximizing traction
when you accelerate from a standing
start or speed up while already
underway. The system recognizes any
tendency for the vehicle to assume an
instable attitude such as oversteer and
understeer, and counteracts this
tendency with a combination of gradu-
ated reductions in engine torque and
braking intervention at individually
selected wheels. DSC provides optimal
stability Ð within the limits defined by
the laws of physics.
The system automatically assumes
operational status each time the engine
is started.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 22.
The indicator lamp flashes:
The system is actively regulating drive
torque and braking force.
The indicator lamp does not go out
after the engine is started, or it comes
on during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the
button. You can continue to drive the
vehicle normally, but without DSC.
Please respond to any suspected
defects by referring the problem to your
BMW center.
To deactivate the systemPress the button, the indicator lamp
comes on and stays on.
When DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following rare circumstances, it
may be effective to deactivate the DSC
for a short period of time:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
To maintain vehicle stability,
always drive with the system
switched on when possible.<520de035
