Manual convertible top, roadsterWeather protectionThe convertible top combines reliable
protection from the elements with
simple, convenient operation. Here are
a few tips to ensure that you have plea-
sure with your 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. In addition,
keep valuables only in the locked
luggage compartment, even with the
convertible top closed.
Never mount a roof-mounted luggage
rack on the convertible top. Please
contact your BMW center for suitable
securing devices and additional acces-
sories.
To prevent damage, do not operate the
convertible top at temperatures at the
freezing point.
To open 1. With the doors closed, lower the side
windows a few inches (centimeters)
2. To release the convertible top: pull
the levers outward on the left and the
right of the convertible top frame
(refer to the illustration)367de046
3. Raise the convertible top approx. 8 in
(20 cm) from the convertible top
frame on the inside to relieve tension
on the top, refer to arrow 1
Be sure that the convertible top
folds at the front linkage joints
first, refer to arrow 2. If it does not, the
convertible top linkage could be bent.<
4. Continue to raise the top at the front
and push it toward the rear into the
convertible top compartment.
In the process, make sure the rear
window is laid down evenly and free
of creases. To prevent the rear
window from being scratched, a soft
cloth should be laid in the window
fold367de399

Airbags Transporting children safely This is the correct way a larger child
should sit wearing the safety belt when
side airbags (arrow) are provided.367de360
Before installing any child-
restraint system, please read the
following:
Never install a rear-facing child-
restraint system in the passenger seat
of this vehicle.
If the airbag deploys and hits the back-
rest of the rear-facing child seat, it is
likely that the child sitting in the rear-
facing child-restraint system will be
seriously injured or killed.
If it is necessary for a child (not an
infant) to ride in the vehicle, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with the
safety belt. Younger children should be
secured in an appropriate forward-
facing child-restraint system that has
first been secured with a safety belt.
In the interest of the child's safety,
please read carefully and comply with
the instructions for installation and use
provided by the child restraint's manu-
facturer whenever you use such a
device.
Do not allow children to lean out of a
child-restraint system toward the door
or instrument panel, as otherwise
serious injuries may result if the airbag
deploys. Always ensure that all occu-
pants (of all ages) remain properly and
securely restrained at all times.
Read carefully and comply with the
safety precautions covering safety belts
on pages 52, 53. If you do not, the
protective function of the safety belts
will be limited.<

Heating and ventilationAir distribution
You can direct the airflow onto
the windows , toward the
upper body and into the foot-
well . All intermediate settings are
possible. In this position , a small
volume of air is directed onto the
windows in order to keep them free of
condensation.
A "6 o'clock" position is recommended
as the normal operating setting.
Temperature
In order to increase the temper-
ature of the passenger compart-
ment, turn to the right (red). For
rapid heating, turn completely to the
right. Then select an interior tempera-
ture which is pleasant for you.
Air supply
You can select blower speeds
from 1 to 4. Both heating and
ventilation become more effec-
tive as the air supply rate is increased.
In position 0, the blower and the heater
are switched off.
Draft-free ventilationYou can adjust the air outlets for the
upper body area completely for your
personal comfort:
Use the rotary dial 2 to open and close
the vent throughout an infinitely-vari-
able range. With the levers 1, you can
direct the airflow to the side. Adjust the
airflow up or down by rotating the vent
grill.
Set the outlets so that the air flows past
you and is not directed straight at you.367de224

Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð warmed
again when the air conditioner system
is switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). This will
help to prevent condensation from
forming on the windows.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
If there are unpleasant odors in
the outside air, you can tempo-
rarily block the supply of the
incoming air. The system then recircu-
lates the air currently within the vehicle.
If the windows fog over in the
recirculated-air mode, switch this
mode off and increase the air supply as
required.<

Cargo loadingStowing cargoIf you are transporting cargo in your
coupe:
>Load heavy cargo as far forward as
possible Ð directly behind the
luggage compartment partition Ð and
as low as possible
>Cover sharp edges and corners
>Do not pile objects higher than the
top edge of the backrest
>Pull the partition net
* out (refer to
page 93). Be sure that no items are
able to penetrate the partition net.

Securing cargoFor securing luggage, you can obtain
load-securing devices
* from your BMW
center. The lashing eyes located in the
luggage compartment serve for
mounting these load-securing devices.
Comply with the information enclosed
with the load-securing devices.
367de627
Z3 cou
pe
Always position and secure the
cargo correctly. If you do not, it
can endanger the passengers during
braking or evasive maneuvers, for
example.
Do not exceed the approved gross
vehicle weight or the specified
maximum axle loads (refer to
page 172), otherwise the vehicle's
operating safety is no longer assured
and you are in violation of the law.
Do not carry hard or heavy objects
unsecured in the passenger compart-
ment. If you do so, they may be
projected through the air during braking
and evasive maneuvers, for example,
thus endangering vehicle occupants.<

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following:
Engine and differentialUp to 1,200 miles (2,000 km):
Drive with varying engine and road
speeds, but do not exceed 4,500 rpm
or 100 mph (150 km/h).
Comply with local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
After you have driven 1,200 miles
(2,000 km), you can gradually increase
the engine and 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.
TiresDue to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until an initial
break-in period has elapsed. You should
therefore drive with extra caution during
the initial 200 miles (300 km).
Comply with local and state maximum
speed limits.
When the vehicle is operated 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 or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads.<
Brake systemApprox. 300 miles (500 km) must
elapse before the brake pads and
rotors achieve the optimal surface and
wear pattern.
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 light up
when the parking brake is applied.
Vacuum for the brake system booster
on your BMW is available only when the
engine is running. When you move the vehicle with the engine off Ð for instance
,
by towing Ð substantially higher levels
of pedal force will be required to brake
the vehicle.<
ClutchThe clutch will reach optimal function
after approx. 300 miles (500 km). Shift
gears carefully during the break-in
period.
