NOTE-
The Key Memory function of the GM responds to the ley
identification number of each key If the keys are not initial-
ized
in the same orderprior to initialization, the ley memory
functions activated by the
l(eys will not be assigned correctly.
Always initialize the keys
in the same order.
es momentarily.
Release both buttons. GM immediately locks and unlocits
doors to signal successful initialization.
Remote system coding
* Initialize remaining lteys, repeating steps above.
The E39 remote entry system uses coded signals for security
purposes. The code signal sent by the transmitter is changed
every time the vehicle is lockedlunlocked with the transmitter.
A separate code signal is used for each transmitter that is ini-
tialized to the system. This allows for each transmitterto oper-
ate independently of the others.
Due to the changing of the code each time the buttons are de-
pressed, the system allows for a
lacit of synchronization be-
tween the transmitter and receiver. This would occur
if the
buttons on the transmitter are pressed inadvertently.
Up to
100 erroneous actuations of the transmitter are auto-
matically corrected
forby the control module. If more than 100
actuations are present, the operator need only to press the
button a second time to restore system operation.

Central Locking and ~nti-~hefil
Key Memory
Whenever one of the FZV keys is used to lock or unlock the
car, the user is identified by the GM. A maximum of four
keys
can be programmed with the Key Memoryfeature. The use of
the personalized key then triggers Car Memory functions
such as heating
I AIC (IHKA) settings or memory seat position
adjustment.
Most programming of Key Memory requires the use of
BMW
scan tools (DISplus, GT1 or MoDiC). However, features such
as
IHKA blower speed and temperature store automatically
without the use of scan tools.
Available Key Memory functions vary based on vehicle equip-
ment. The functions that can be set include:
Automatic locking after start off (vehicle speed)
Selective locking
Heating
1 AJC blower speed, heated or cooled air distribu-
tion, automatic blower setting
Trunk lid soft close (SCA)
< The optional sofl close trunk feature is called SCA. The SCA
actuator is located in the panel below the trunk lid.
1. SCA motor and actuator located behind trunk trim in
rear wall of
trunlc
2. Lower edge of trunlc seal
3. Cam in open position
4. Cam in closed position
The actuator is controlled by a load relay in the General Mod-
ule (GM). The closing cam is mounted on an eccentric that is
driven by the actuator. The cam always turns
180" in the
same direction to open or close the trunk.
