Car Memory / Key Memory
The Car/Key Memory feature provides the flexibility of allowing the owner to customize cer-
tain functions of select vehicle systems and automatically identifies users of the vehicle by
a key identification signal provided by the remote keyless entry system (FZV).
Car & Key memory is marketed as a combined feature but is actually two separate func-
tions of the select vehicle control systems.
Car Memory: The owner is provided with a list of available system functions that can be
customized to their liking. Prior to delivery, the DIS or MoDiC is used to encode the
owner’s chosen selections into the appropriate control modules.
These choices become a permanent function of the control module and can only be
changed by re-encoding with the DIS or MoDiC at a BMW Center.
This feature has been available for some time via the ZCS Conversion Feature but has never
been fully utilized or officially presented to the vehicle owner as a feature of their vehicle.

INTERIOR PROTECTION (UIS)
The UIS monitors the vehicle interior for motion through ultrasonic sound waves. The UIS
is a combined transmitter and receiver.
The X5 UIS sensor is incorporated into the
rear seat interior light trim cover. It is a two
piece unit with cable connection to the rear
transmitter/receiver.
The UIS and trim panel are clearly identified
with arrows indicating forward mounting
direction.
Due to the design of the vehicles interior,
the sensor is uni-directional and must be
installed in the proper direction to ensure
proper operation of the system (trim cover
ensures directional installation).
Every time the DWA system is armed (signal STDWA), the sensor adapts to what ever
objects might be stationary in the interior.
The sensor emits ultra sonic waves in a pro-
grammed timed cycle. It receives echos of
the emitted waves.
The UIS amplifies the received sound wave
signals and compares them with the trans-
mitted waves. The UIS also checks the
incoming echos for background hiss (wind
noise through a partially open window) and
adapts for this.
• If the echos are consistently similar, no movement is detected,
• If the echos are altered, (inconsistent), the UIS determines motion in the interior com-
partment.
If motion is detected, the UIS changes to a constant cycle and the echo is compared again.
If the inconsistency is still present the UIS sends the activate siren signal (INRS) to the GM.
As with the tilt sensor, the UIS is also switched OFF when the vehicle is locked two times
within ten seconds. This allows the sensor to be switched OFF for transportation purpos-
es.

DRIVER’S SEAT MEMORY (CAR Memory Influence)
The PM-SM can be encoded to recall a specific seat position for a vehicle user when the
GM signals the SM to automatically recall stored positions separate of the 1-2-3 button
selections.
This feature is encoded through the car memory function and activated by the key memo-
ry function. The PM-SM will monitor the seat position and store it in another area of it's
memory when the vehicle is locked with the remote keyless entry system. The GM sends
a request to memorize the seat position and store it for FZV key user 1,2,3 or 4.
If another user of the vehicle changes the seat position the PM-SM restores the memory
position the next time the specific key is used to unlock the vehicle.
This feature can be further modified to activate the position recall based on the owner's
selected activation scenario, for example: The owner can choose to :
• Disable this feature,
• Initiate memory recall when the unlock signal is initially sent before a door is opened.
• Initiate memory recall when the unlock signal is sent but only when the driver's door is
opened.
See Car Memory Key Memory for additional information.
POWER SEAT DIAGNOSIS
The PM-SM communicates with the DIS or MoDiC via the K bus - instrument cluster gate-
way - to the P-bus. The PM-SM monitors the seat motors and circuits as well as it's inter-
nal operation. Any detected faults are stored in the PM-SM fault memory and are called up
when diagnosing the system with the Fault Symptom diagnostic plan.
The PM-SM also provides status display to the DIS of its input and output control signals
as well as component activation.
