Using the Panic Alarm
If you are near your vehicle and feel threatened, you may
activate the alarm to call attention to it.
To activate the PANIC alarm, push and hold the PANIC button
on the remote for longer than 1.5 seconds. The horn will sound and
the headlamps and tail lights will flash for thirty (30) seconds.
To turn off the alarm, press the LOCK or UNLOCK buttons or hold
the PANIC button down for longer than 1.5 seconds.
Replacing the Batteries
The remote entry transmitter is powered by two coin type Sanyo
CR2016 3 volt batteries (included). If you notice a significant
decrease in operating range, the batteries should be replaced.
Replacement batteries can be purchased at most pharmacies, watch
stores or at your Ford or Lincoln-Mercury dealer.
NOTE: The operating range of the remote entry system can
also be affected by weather conditions (such as very
cold temperatures) or structures around the vehicle
(buildings, other vehicles, radio and TV towers,
etc.). Typical operating range will allow you to be up to
49 feet (15 meters) away from your vehicle.
