Cadillac 2007 XLR - Manual (Page 223)

A person approaching the outside of the locked
vehicle without an authorized keyless access
transmitter, however, will not be able to open the
door, even with a transmitter in the vehicle.
You may temporarily disable the passive door
locking feature by pressing the door unlock switch
for three seconds on an open door. Passive
door locking will then remain disabled until a door
lock switch is pressed or until the power mode
transitions from the off power mode.
You can select to not have the horn sound when
the passive lock occurs. If you choose this
setting, the doors will automatically lock eight
seconds after you turn the ignition off, remove a
keyless access transmitter from the interior of
the vehicle, and close both doors.
You can also select to have the horn sound once
when the passive lock occurs. If you choose
this setting, the doors will automatically lock and
the horn will chirp eight seconds after you turn the
ignition off, remove a keyless access transmitter
from the interior of the vehicle, and close
both doors.
If you are parking in a quiet area and do not want
the horn to sound when the doors lock, press
the lock button on the keyless access transmitter
immediately after removing it from the interior
and closing the doors. This will lock the doors and
cancel the passive locking for this ignition cycle.
The DIC will display PASSIVE LOCKING OFF,
SILENT PASSIVE LOCK, or HORN AT PASSIVE
LOCK. Press the OPTIONS button to change
the setting.
Passive Unlocking
This feature allows you to select which doors will
automatically unlock when you approach and
open the driver’s door with your keyless access
transmitter. You can choose to have the driver’s
door unlock or both doors unlock. See Door Locks
on page 73 for more information.
The DIC will display PASSIVE UNLK DRIVER or
PASSIVE UNLK BOTH. Press the OPTIONS
button to change this setting.
