Lincoln RESCU System Limitations
Service restricted to 48 contiguous states
Your Lincoln RESCU System can be activated
anywhere within the 48 contiguous states. If an
activation occurs outside of this region, the Lincoln
Security Response Center will not be able to assist
you.
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 is discharged or
disconnected.Potentially inoperative if vehicle involved in
accident
If the vehicle is involved in an accident, some
components could be damaged, rendering your
Lincoln 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 the 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.
154Inoperative if cellular signal marginal or
unavailable
Since the Lincoln RESCU System utilizes the
vehicle's cellular phone, it can only be operated
in geographical areas with cellular coverage.
Although approximately 90 percent of the U.S.
population lives and works in cellular coverage
areas, there are various rural or mountainous
areas where coverage is marginal or does not
exist. If an activation occurs in this situation,
the messages "NO CELLULAR SIGNAL" and
"WAITING TO ACQUIRE" will alternately be
displayed on the Message Center. If after
several attempts cellular service cannot be
acquired, the message "UNABLE TO PLACE
CALL" will be displayed, the assistance request
wfll be terminated and the phone will return to
its normal operating mode.

High Current Fuses
High current fuses are circuit protectors that are
part of the wiring harness for some electrical
equipment. These, like fuses, open when the
circuit load exceeds their amperage rating. High
current fuses may be purchased from your Ford or
Lincoln-Mercury dealer.
The high current fuse panel is located in the engine
compartment on the left-hand fender apron./!\ WARNINGAlways disconnect the battery beforeservicing high current fuses.Ford recommends that high current fuses be
replaced by a qualified technician.
