Replacement keysReplacement keys are available exclu-
sively through your BMW center. Your
BMW center is obligated to ensure that
a person requesting a key is authorized
to do so since the keys belong to a
security system (refer to "Electronic
vehicle immobilizer" on the next page).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
Whenever you receive a new
replacement key, turn that key to posi-
tion 2 in the ignition lock once (ignition
switched on) and then back. This allows
the electronic vehicle immobilizer to
"learn" the new key.<

Electronic vehicle immobilizerThe key to securityThe electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW – you do not have to
adjust or activate anything. This elec-
tronic immobilization system is
designed to reduce the susceptibility of
the vehicle to theft by making it impos-
sible to start the engine using any
means other than the special keys
furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for indi-
vidual keys (in the event a key is lost,
for instance). A deactivated key can no
longer be used to start the engine.
How the electronics workAt the heart of this system is an elec-
tronic chip which 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 not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine.<
For US owners onlyThe transmitter and receiver units
comply with part 15 of the FCC (Federal
Communications Commission) regula-
tions. Operation is governed by the
following:

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 or
below 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 inches (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
fold.367de399

schematic of the fasteners for the
convertible cover.
To secure, press the outer ring of the
cover fastener onto the mating piece on
the vehicle (refer to the arrows).367de274
The attachment points of the cover are
indicated by the four arrows in the illus-
tration.
1 Position the convertible cover on the
convertible top compartment and
align the upper portions of the
fasteners with the lower portions on
the vehicle.

cover under the edge of the convert-
ible top compartment.
5 Check the convertible cover to be
sure it is properly secured.
In order to avoid damage and
soiling of the inside of the convert-
ible top, always drive with the convert-
ible cover installed.<
Be sure that the cover is secured
properly on the vehicle. If it is not
firmly secured, the flow of air while
driving could loosen the cover at higher
speeds.< 367us077

Manual convertible top – roadster>To avoid damage, carefully fold the
cover and store it in the luggage
compartment.
Do not position heavy objects on
the cover.
If you store the cover away from the
vehicle, the cover should be spread
out.<
2 When the doors are closed, lower the
side windows slightly.367de247
3 Pull the release lever away from the
frame as far as possible.
4 Holding the convertible top at the
front convertible top frame, lift it out
of the convertible top compartment
and fold it forward.
When folding the convertible top
forward, do not grasp it by the
side linkage. If you do so, there is a risk
of injury to your hands and fingers.<
5 Insert the pins 1, on the left and the
right, into the guides in the wind-
shield frame. Using the handle recess
in the center of the convertible top
frame, pull the convertible top down.
Hold the top in this position and
secure both fasteners (refer also to
page 97).367de047
Be sure that the fastener hooks 2
on the left and right are securely
engaged in the frame of the windshield.
If they are not, the convertible top could
open while the vehicle is moving.<
At higher speeds, it may occur
that the lower air pressure which
is created in the passenger compart-
ment will cause the top or the rear
window to flutter. Increase the air
supply via the ventilation controls so
that a low pressure draft does not occur
in the vehicle.<
