POWER WINDOWS
The power window operation on the E53 is similar to previous systems. Features of the
system include:
• Control of the front and rear door window motors is carried out directly by the GM.
• One-touch operation in both directions on all four windows.
• Cable type window regulator used for all windows.
• Anti-trap detection is provided by the pressure sensitive finger guard .
• Push/pull window switches
• The rear window switches located in the rear doors can be deactivated by the pressing
child lock out switch in the center console.
• Convenience closing/opening of the windows from the driver's lock cylinder or
convenience opening only from the FZV remote key (FZV operation can be owner
customized with the Car Memory Function).
• Window operation with the ignition switched off until a door is opened or 16 minutes has
elapsed after the key is switched off.
• Window load switching is through relays integral of the GM for rear windows and in the
respective door switchblock modules for the front windows. The current draw is
monitored for end limit position. The maximum run time for the window motors is limited
to 8 seconds. This allows the motors to be switched off if the end limit load sensing fails.

AUTOMATIC CONTROL FUNCTION
The GM provides 12 volts (linear application providing soft on feature) to the interior light-
ing circuit when the one of the following input signal statuses change:
• Door contact hall sensor active (door opened)
• An Unlock request from the driver's door key lock hall sensors are received. This only
occurs if the ignition switch is off.
• An Unlock request is from the FZV keyless entry system is received via the K bus. This
only occurs if the ignition switch is off as well.
• The ignition switch is switched off and the vehicle exterior lights (LCM III) have been on
for a minimum of 2 minutes prior. This information is provided to the GM via the K bus.
• Active crash signal from the MRS III control module.
• Lock button of FZV key is pressed with the vehicle is already locked (interior search
function).
The GM gradually reduces the full 12 volt power supply (linear reduction providing soft off)
until the lights are off when the following input signal statuses change:
• Immediately after the ignition switch is turned to KL R with the driver's door hall sensor
door contact closed.
• When the vehicle is locked (single or double) with the door contacts closed.
• When the vehicle door contacts are closed. The lights remain on for 20 seconds and
then go to soft off.
• After the interior search function is activated, the lights will automatically turn off (soft off)
after 8 seconds.
• After 16 minutes with a door contact active (open door) and the key off, the lights are
switched off (consumer cutoff function).
• The component activation function of the DIS also has the ability to switch the lights.
The Interior lighting output circuit of the GM is approximately 3.5 amps with all lights on.

DWA ARMING/DISARMING
• The DWA is armed every time the vehicle is locked from the outside with the door lock
cylinder or FZV key.
• The LED in the rear view mirror flashes as an acknowledgment along with the exterior
lights and a momentary chirp from the siren.
• The GM monitors all required input signals for closed status (door closed, tailgate
closed, etc.) The inputs must be in a closed status for a minimum of 3 seconds for the
GM to include them as an activation component. If after 3 seconds any input signal not
in the closed status is excluded (this is acknowledged by the DWA LED) preventing false
alarm activation's.
• If the DWA is armed a second time within 10 seconds, the tilt sensor and interior pro-
tection sensor are also excluded as alarm activation components. This function is use-
ful if the vehicle is transported on a train or flat bed truck to prevent false alarm activa-
tion's.
• While armed the tailgate can be opened with out the alarm being triggered as follows:
- If opened with the tailgate remote button via the FZV, the GM prevents the alarm
from activating. (This feature is customizable under the Car Memory function).
- If opened with the key at the tailgate lock cylinder the tailgate key position switch
signals the GM and in the same manner prevents the alarm from activating.
In either case, when the tailgate is returned to the closed position, it is no longer con-
sidered as an activation signal.
Panic Mode Operation: When the tailgate button is pressed and held, the GM is signaled
to activate the siren for the Panic Mode. The panic mode will function with either an armed
or disarmed DWA system.
EMERGENCY DISARMING
Emergency disarming occurs automatically if a key is used to turn the ignition switch on and
the EWS III accepts it. The EWS III signals the GM to unlock the doors and deactivate the
DWA.

DRIVER’S SEAT MEMORY FUNCTION
As with previous systems, the seat memory feature of the SM stores three seat positions
for recall. The positions are stored in a non-volatile memory preventing loss of positions if
in case the SM or the battery is disconnected.
The additional buttons on the SM (M) pro-
vide activation of recording memory position
and (1-2-3) for storing or recalling a specific
seat setting.
Storing current seat position:
• Seat in desired position,
• Ignition switch in KL R,
• Press the M button until it illuminates
• Within 7 seconds press the 1,2 or 3 but-
ton to store.
The stored position can be recalled at any time by pressing the appropriate memory loca-
tion button (1-2-3).
MEMORY RECALL MODES OF OPERATION
Depending on current SM input signals via K-Bus, the memory recall operates in two dis-
tinctly different modes:
• One-touch mode (TTB),
• or press and hold mode of operation (DTB).
If the following input signal status is current, the SM resets the seat position by a momen-
tary“one touch”of the selected memory button.
• Ignition switch off with the driver’s door open, or,
• KL R on, door open or closed
If the following input signal status is current, the SM resets the seat position by a continu-
ous ”press and hold”of the selected memory button.
• Ignition switch off with the driver’s door closed
• KL 15 on, door open or closed.

SLEEP MODE
To lower the constant battery draw when the vehicle is parked, The complete ZKE system
will go into the “Sleep Mode” 16 minutes after the ignition has been switched off and no
further ZKE function is active.
Approximate X5 Battery draw: • Ignition switch off = approx 750 mA.
• One minute after = approx. 560 mA.
• After 16 minutes (sleep mode) = approx. 18 mA.
All modules in the ZKE system will go into the sleep mode. The P-Bus remains active, how-
ever no data transfer takes place until a wake-up request is received. The general module,
door modules or keyless remote module can wake the system up and put the ZKE back
on line. The K-Bus is not active in the sleep mode, however the GM III of Remote Entry
Module can put the K-Bus back on-line with a wake-up request.
SLEEP MODE CRITERIA: KL R, 15 OFF and no further function activated for 16 minutes.
WAKE UP CRITERIA: KL R or 15 “ON” or a change in one of the signal states listed below.
