"Service Engine Soon" warning lamp
may come on, refer to page 22.<
Open the fuel filler cap:
To open the fuel filler door, turn the fuel
filler cap counterclockwise and remove
the cap. Place the filler cap in the
bracket attached to the fuel filler door.

When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system.
If the filler nozzle is operated correctly,
the fuel tank is full when it shuts off the
first time.
Tank capacity, approx. 13.5 gal.
(51 liters), incl. a reserve capacity of
approx. 2.1 gal. (8 liters).
Close the fuel filler cap:
Position the cap on the neck. Turn the
cap clockwise to the stop.
Close the filler cap carefully after
refueling until a "click" is heard.
While closing, be sure not to squeeze
the strap which is fastened to the cap.
A loose or missing cap will activate the
"Service Engine Soon" lamp.<
Close the fuel filler door.
When handling fuels, comply with
all of the applicable safety
precautions and regulations pertaining
to fuels.
Never carry spare fuel containers in
your vehicle. Whether they are empty or
full, these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<

Electronic vehicle immobilizerThe key to securityThe electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW Ð 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.<

Opening and closing Ð from the outsideWith the remote control
*
The remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides an additional
function which you can only execute via
the remote control:
>To switch on the interior lamps, refer
to page 34.
With this function, you can also
"search for" the vehicle, when parked
in an underground garage, for
instance.
Whenever you unlock (lock) the vehicle,
you simultaneously deactivate (activate)
the anti-theft system and switch the
interior lamps on (off).
Master keyKeys with remote control units are
master keys, refer to page 30.
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle keys with you
so that the vehicle can be opened again
from the outside at any time.<
Every transmission is indicated by a
light signal. If the signal no longer lights
up when a button is pressed and
locking with the remote control is no
longer possible:
Change the battery, refer to page 144.367de383
To prevent unauthorized use of
the remote control, surrender only
the door and ignition key 3 or the spare
key 2 (refer to page 30) when leaving
the vehicle for valet parking, for
example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Luggage compartment lidTo lock separatelyTurn the master key to the right past the
pressure point and then pull it out in the
horizontal position
This locks the luggage compartment
and disengages it from the central
locking system. If you then surrender
only the door and ignition key (refer to
page 30), access to the vehicle through
the luggage compartment is not
possible. This is recommended for valet
parking, for instance.Manual operation(in the event of electrical malfunction)
Turn the master key in the lock of the
luggage compartment lid to the left to
the stop Ð the luggage compartment lid
opens slightly.
The luggage compartment is locked
again as soon as it is closed.
To closeThe illustration depicts the luggage
compartment lid of the Z3 coupe.
The handle recess in the interior trim
panel of the luggage compartment lid
(arrow) makes it easier to pull the lid
down.
On the Z3 roadster, the handle recess
is located to the left of the lock mecha-
nism.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.< 367de625
Z3 cou
pe
Operate the vehicle only when the
luggage compartment lid is
closed, since exhaust fumes could
penetrate the interior of the vehicle.
Should it be absolutely necessary to
operate the vehicle with the luggage
compartment lid open (coupe; roadster
with closed convertible top):
>Close all windows. On the coupe,
close the sunroof
>Increase the air supply of the heating
and ventilation system to a high level.
Refer to page 82 or 86.<

Jam protectionIf one of the windows comes into
contact with an object between the
window and roof frame when it is
closing, the closing cycle is interrupted
immediately and the window will open
again slightly.
You can override this jam protec-
tion function (if there is an
attempted unauthorized entrance from
the outside, for instance) by pressing
the switch beyond the resistance point
and holding it.<

pe
To prevent injuries, exercise care
when closing the sunroof. Keep it
in your field of vision until it is closed.<
To avoid pressure or drafts in the
passenger compartment when the
sunroof is open, keep the air vents in
the instrument panel open and increase
the air supply if necessary, refer to
pages 82 and 86.

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
2. Lift the cover at the rear, reach

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 slightly367de247
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 convert-
ible top frame, pull the convertible
top down. Hold the top in this posi-
tion and secure both fasteners, refer
also to page 109.367de047
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.<
