Manual transmission
Turn signal/Headlamp flasher
Every time you shift gears, always de-
press the clutch pedal all the way down,
pushing the manual-shift gear lever into
the desired position.
Depress the clutch even when starting
the engine, otherwise, a lock will pre-
vent the engine from being started.
The shift lever's neutral plane is located
between third and fourth gear.
When shifting from each gear into
"Neutral," the shift lever returns auto-
matically to this gear plane because of
its spring loading.520de114
When shifting gears in the fifth/
sixth gear, be sure to press the
gear lever to the right in order to pre-
vent inadvertent selection of a gear in
the third/fourth.<
Reverse Select "Reverse" 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.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead. A
slipping clutch increases clutch wear.<

sound from the relay).
If the indicator lamp and the clicking
from the relay are faster than normal,
one of the turn indicators has failed.To signal brieflyPress the lever up to but not beyond
the pressure point. It then returns to the

Set the clock From ignition key position 0 on:
To set ahead: turn the button to the

To set back: turn the button to the left.
If you keep holding the knob turned,
you will find the setting faster.520us007
With the Multi-Information Radio, you
can operate the navigation system and
few other cellular phone functions, in
addition to your car radio.
Please refer to the supplementary

sound system for detailed information
on adjusting and operating the Multi-
Information Radio. Outside temperature You can have the outside temperature

Heating and ventilation/Air conditioningAir supply
You can select blower speeds
from 1 to 4. The higher the set-
ting, the greater the amount of
heat and air supply. In position
0, the blower, heating and air condi-
tioner 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 con-
ditions (refer also to the illustration and
overview on page 70).
Recirculated air mode
If there are unpleasant odors
in the outside air, you can tem-
porarily block the air supply.
The system then recirculates
the air currently within the vehicle.
If the windows fog over when
using recirculated air, turn off the
recirculated air mode and increase the
airflow if necessary, or press the button
for "defrosting and defogging the win-
dows."<
Venting in outside air
Recommended when driving
with the convertible top open.
The degree to which the pas-
senger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/Venting in outside
air
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner system is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Do not turn on the air conditioner if out-
side 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
Both systems are operating.
Another advantage is that a
hot vehicle cools down more
quickly with the convertible
top closed. This way, you will get the
lowest possible vented air temperature
(turn the temperature rotary dial all the
way to the left).

To open Pull the handle. The lamp comes on.
A beverage can holder is stored in the

To prevent injury in the event of a
crash, close the glove compart-
ment immediately after every use.<520de049
To lockUse one of the master keys. The glove
compartment, the storage shelf for the
cellular phone and the luggage compart-
ment lid are now locked.
A master key is also required for
unlocking.
If you turn over only your door and
ignition key for valet parking (refer
to page 28), for example, access to the
glove compartment,
the storage shelf
for the cellular phone or
the luggage
compartment
is not possible when the
vehicle has been locked.<
Manual operation(in the event of electrical malfunction)
With the key in the last key positions,
you can unlock or lock the glove com-
partment.

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 items
>Do not pile objects higher than the
top edge of the backrest.
Do not stow either heavy cargo or
cargo with sharp edges and cor-
ners 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 pre-
vent 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 nec-
essary. Refer to page 43.
Always position and secure the load
correctly. If you do not, it can endanger
the passengers during braking or eva-
sive 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 un-
der braking. This is because: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
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 vehi-
cle exceeds a speed of approx. 6 mph
(10 km/h). The ABS is deactivated
whenever the vehicle's speed drops
back below approx. 4 mph (6 km/h).
This means that the wheels can tend
to lock in the very final phase of a panic
stop, which in actual practice is not
critical.
The ABS system works best in situa-
tions requiring maximum pressure on
the pedal (full braking). Since the vehi-
cle maintains steering responsiveness,
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, com-
bined 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 in-
stance), 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.
