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.<

Central locking system Opening and closing Ð from the outsideThe conceptThe central locking system becomes
operational when the doors are closed.
The system simultaneously engages
and releases the locks on the
>doors
>luggage compartment
>fuel filler door.
The central locking system can be
operated
>from outside via the door locks, the
luggage compartment lock as well as
via the remote control
*
>from inside via the safety lock
buttons (locks doors only).
The anti-theft system is automatically
activated whenever you activate the
central locking system from outside the
vehicle. It prevents the doors from
being unlocked with the lock buttons or
release handles.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.

Never lock the doors when leaving
passengers in the vehicle, as they
would then be unable to unlock the
door from the inside.<
Convenience locking modeThe electric power windows can also
be closed via the door locks:
When the doors are closed, hold the
key in the "Lock" position.367de011
Watch the closing process care-
fully and be sure that no one is
trapped by the closing motion. The
closing process stops immediately
when you release the key.<

The remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.

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 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

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

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.

After the ignition has been switched off:
Operation is still possible for up to
15 minutes in ignition key position 0 or
if the ignition key has been removed, as
long as no doors have been opened.
Because the power windows are
sealed at high pressure to prevent
wind noise when closed, a powerful
motor is required for efficient closing.
When closing the windows, always
ensure that they are not obstructed in
any way. Unsupervised use of these
systems can result in serious personal
injury. Remove the ignition key to deac-
tivate the electric power windows
whenever you leave the vehicle. Never
leave the keys in the vehicle with unsu-
pervised children.
Never place anything that could
obstruct the driver's vision on or next to
the windows.<
