I Door Windows
/ Anti-trap strip
Power window motors
The window motors are mounted on cable regulators. The
window motor control circuit consists of two wires for operat-
ing the motor in both directions.
The motors are activated by relays in the GM
Ill. The relays
provide either power or ground depending on the direction of
window travel. The GM
Ill controls the polarity based on a re-
quest to run the window from a window switch or a conve-
nience
openinglclosing signal.
Convenience openinglclosing
The GM Iii provides the convenience openlclose feature, pro-
viding control of the power windows (and sunroof) from out-
side the vehicle with the key in the driver's door lock. The FZV
(remote key) provides the same function for window opening
only.
Anti-trap protection is active during convenience closing from
the driver's door lock.
If the GM receives a request to operate convenience closing
or opening for more than
110 seconds, the function is deacti-
vated and a
fault code is stored.
Window anti-trap protection
4 A rubber pressure guard is located at the top edge of each
door frame. It consists of two contact strips that close when
subjected to pressure. When the contact strip closes (for ex-
ample, a hand is trapped between the top of the window and
the door frame), an anti-trap signal is sent to the GM
Ill. The
window immediately (within
10 milliseconds) reverses direc-
tion. This feature does not require
initialization.
The E39 pressure sensor finger guard has a resistance of 3
Kw and it is monitored for open circuits. When pressed, the
monitored resistance changes to
< 1 Kw. if anti-trap protection
becomes faulty the one touch window closing will not func-
tion.
Window anti-trap protection is
only active in the one touch
and convenience close modes of operation. If the window
switch is pulled and held, anti-trap protection will not function.
The anti-trap contact strip has a resistance of
1.2 K Ohm and
it is monitored for open circuits. Faults with the anti-trap sys-
tem will cancel the one touch feature requiring the window
switch be held to close the window.

lnterior trim repairs
lnterior trim and finish panels are clipped or screwed into
place. Many of the trim retaining clips are designed
to be used
only once. When removing trim that is held in place with clips,
it is a good idea to have spare clips on hand before beginning
the job.
WARNING-
Special precautions must be observed when servicing the
BMWSupplementai Restraint System (SRS). Serious inju-
ry may result if system service is attempted by persons un-
familiar with the BMW
SRS and its approved service
procedures. BMW
speciiies that all inspection and service
should be performed by an authorized BMW
dealer.
Before performing any work involving airbags, discon-
nect the negative
() battery cable. See 721 Airbag
System (SRS).
Airbags contain a back-uppowersupply within the SRS
control module. A
5 second discharge period should be
allowed after the battery cable has been disconnected.
CAUTION-
* When working on electrical switclies or lights, always dis-
connect the negative
(-) cable from the battery and insu-
late the cable end to prevent accidental reconnection.
a Prior to disconnecting the battery, read the battery dis-

I Central Locking and Anti-Theft
Driver's door lock
The
lock/unlock signals are sent as input to the door module
from two microswitches on the lockcylinder. The driver's door
module carries out the locking
/ unlocking functions of the
driver's door through its final stage control.
The signal to lock the remaining doors, trunk or tailgate and
fuel flap is sent over the P-Bus to the GM and the passenger
door module. Activation of the passengers door
loclt is carried
out by the passenger door module. The rear doors, trunlt or
tailgate and fuel flap are
locked by the f~nal stage in the GM.
When
locked from the outside, all doors are set to the double
lock position and the GM will not carry out any unlock com-
mands from the central
loclc button or remote trunk release
button.
Selective unlocking
When unlocking with the key or the remote transmitter, the
first unloclcrequestwill only unlock the driver'sdoor. A second
unlock request will unlock the remaining doors, trunk or tail-
gate and fuel flap.
Trunk locking
I
The vehicle can be locked/unlocked from the trunlc loclc cylin-
der. The GM locks the trunk or tailgate, rear doors and fuel fill-
er. The locking command is passed over the P-Bus to the
respective door modules to lock the driver's and passengers
doors.
Locking the trunk and removing the key in the
hor~zontal posi-
tion will set the valet lock and prevent opening of the trunlt
with the central locking system.
Central locking switch
-
< The central locking master control switch (arrow) is located
in the center console behind the shifter.
The central locking button will only single
loclt the doors
and trunk. The filler flap remains unloclted for refueling pur-
poses.
If a door is opened from inside while centrally locked, the
remaining doors remain locked.
The open door can be relocked, when closed, by manually
locking or pressing the central locking button twice. This
synchronizes the door
locks.

DWA alarm
The DWA alarm system is
armedldisarmed when thevehicle
is locked / unlocked from either the door or trunk.
Convenience closing
I opening
The windows and sun roof can be closed or opened by hold-
ing the key in the
loclc I unlock position.
Crash sensor
The crash sensor is located in the left front
kick panel. It func-
tions by unlocking all doors in the event of an accident.
NOTE-
Continuous and repeated locliing / unlocking may cause
timedarrest of
the locliing system. When activated, the timed
arrest lasts for two minutes. The timed arrest does not affect
the crash sensor
unlocliing the doors in case of an accident.
Door locks
The driver's door lock location is the only point outside of the
vehicle where the ltey can mechanically control all of the cen-
tral locking system functions.
4 Door key positions for electrical / manual loclting and
unlocking are:
1. Manual unlock
2. Unlock, DWA disarmed, convenience open
(hold until activated)
3. Neutral position
4. Lock, DWA armed, convenience closing
(hold until activated)
5. Manual lock
The door lock actuators are sealed. self contained units with
no replaceable parts. The
actuators use Hall effect sensors in
place of pin contacts and microswitches to provide DOOR
OPEN
I DOOR CLOSED status signal. Each door lock button
only affects the actuator it controls. There is no effect on the
other doors.
An automatic locking feature activates door locks when a
road speed signal of 4 mph is detected via the K-Bus. The fac-
tory default coding for this feature is OFF, but can be coded
ON for individual users with the Key Memoryfunction. See
Car Memory
1 Key Memory later in this section.

(Central Locking and Anti-Theft
Each rear door is equipped with the child lock-out lever, pre-
venting the door from being opened from the inside regard-
less of loclc button position.
Starting with models produced afler
911997, the General
Module and electronic immobilizer (EWS) interface via the
K-
Bus to monitor double lock status and to initiate double loclc
override. This feature allows the doors to be opened from the
inside if a key accepted by EWS is switched on in the ignition.
See Single lock and double lock function.
The door loclc buttons are mechanically uncoupled from the
actuators when locked. The remote keyless entry system
(FZV) is standard equipment. This allows for elimination of
the passengers side door
loclt cylinder.
Another function of the locking system is the
sofl close trunk
(SCA) system, where applicable.
Single lock and double lock function
(2000 and later models)
On models produced after
911999, each door lock actuator in-
corporates two motors:
Single lock motor controls the mechanical loclc mechanism
when the central lock switch is pressed to single loclc the
vehicle. The loclc mechanism is fully locked at this point but
can stil. be openeo from
the interor by pulng the appropri-
are interior door nandle lwce or by pressing rhe central
lock switch again. When single
lock'function is activated,
the fuel filler flap actuator is not locked.
Double lock motor, also known as central arrest, is activat-
ed only when the vehicle is locked from the outside at the
driver's door lock with a key or when the GM receives a
lock request from the remote entry (FZV) system. In this
case the double lock motor is activated simultaneously
with the single lock motor. The function of the double loclc
motor is to mechanically offset an internal rod in the loclc
actuator, disabling it from unlocking the vehicle from the in-
terior. This prevents the doors from being unloclted by any
means except from an unlock request at the driver's door
or via the FZV remote key.
Lock cylinder safety
4 The driver's door loclc and the trunk loclc incorporate an over-
running loclc cylinder similar to the ignition lock. If any key
other than the vehicle key, or a tool such as a screwdriver or
dent-puller, is inserted into the cylinder, it will cause the cyl-
inder to freewheel or spin.

Remote entry (FZV)
< The €39 remote (keyless) entry system (FZV) uses a tiny ra-
dio transmitter in the vehicle key to
lock and unlock the doors
and the trunk by remote control. There are a number of other
features incorporated in FZV:
Locltinglunloclting of fuel filler lid
Selective unlocking of driver's door (as with key in lock)

* Models to 1999: Key incorporates LED. LED informs oper-
ator that an FZV signal is being transmitted. LED is also
useful indicator of key initialization status and lkey self-test.
Keys delivered with four different colored labels. This is
helpful to differentiate FZV keys during initialization,
pre.
venting possibility of misassigning key ID which would
change coded Key Memory functions.
