Activation and deactivation
When either of the two Lincoln RESCU controls are pressed, or the air
bags are deployed (this will activate the system as an emergency
automatically), a warning light, located in the overhead console, will
begin to flash and status messages will be displayed on the vehicle's
message center, confirming an assistance request has been made. The
warning light will continue to flash throughout the activation.
The system can be activated whenever your ignition key is in the
RUN/START position and for six minutes after your vehicle is turned off.
Once a RESCU control has been pressed, do not attempt to cranks the
engine as this may cancel the activation. In most situations, the
assistance request can only be terminated and the system reset when a
special tone is sent to the vehicle by the Lincoln Security Response
Center. (SeeAutomatic rediallater in this chapter for exceptions.)
Operation will continue even if the vehicle is turned off during an
activation (although visual feedback via the message center will not be
available in this situation).
Cellular phone interface
The cellular phone must be connected to the vehicle and activated for
the system to work. During an activation, Lincoln RESCU takes control
of the vehicle's cellular phone. If the phone is in use, the call will be
terminated and the Lincoln Security Response Center will automatically
be dialed. The cellular handset becomes inoperative and all voice
communication with the operator is accomplished via the cellular phone's
ªhands-freeº microphone.
When an activation is terminated, your phone is left unlocked, in the ON
state and may not return to its previous call restriction or system
selection setting. It can be reprogrammed to your previous setting as
desired.
Refer to your cellular phone user's manual for further information.
Message center interface
During an activation, Lincoln RESCU communication with the vehicle's
message center. Status message describing the sequence of the steps
being executed are displayed, allowing you to visually follow the
activation process. The following messages are typical of those displayed
during an assistance request. They are as shown in the order in which
they would appear:

Lincoln RESCU system limitations
Inoperative if cellular phone inactive or inoperative
Lincoln RESCU utilizes your vehicle's cellular phone and will not operate
if cellular service has not been activated or if the phone is inoperative.
Inoperative if battery discharged or disconnected
Lincoln RESCU is powered by the vehicle's battery and will not operate if
the battery if discharged or disconnected.
Potentially inoperative if vehicle involved in accident
If the vehicle is involved in an accident, some components can be
damaged, rendering your RESCU System inoperative.
Positioning capability degraded if satellite signals obstructed
Vehicle positioning is accomplished by receiving and interpreting signals
transmitted by satellites. If the signals are obstructed positioning
capability could be degraded or lost. This situation will be most prevalent
in urban areas populated with tall buildings. tunnels, underpasses,
parking garages, trees and similar structures could also adversely affect
positioning performance. Under these conditions, the system will operate
but the response center could have difficulty identifying your current
location. (The last valid position obtained before the obstruction is
retained, however, and will be sent.) The operator may depend on you to
provide verbal information regarding vehicle location.
Positioning capability temporarily degraded after battery reconnect
When your vehicle is started, the Lincoln RESCU GPS receiver begins
the process of determining vehicle location. The receiver will search the
sky and attempt to acquire signals from all visible satellites. A real-time
clock and an almanac containing detailed information about satellite
constellation are stored in the on-board computer's memory and are used
to expedite the search. If the vehicle's battery is disconnected, the clock
memory is erased and time and date are lost. Once the battery is
reconnected, it could take approximately 15 minutes to reacquire the
clock and for positioning capability to be restored. During this time, the
system will operate but the response center will not be able to identify
your location. In this situation, the operator will depend on you to
provide verbal information regarding vehicle location.
