Anti-Theft Indicator - Mercury 2009 Grand Marquis Owner's Manual

Locks and Security
Your vehicle comes with two coded keys; additional coded keys may be
purchased from your authorized dealer. The authorized dealer can
program your spare keys to your vehicle or you can program the keys
yourself. Refer to Programming spare keys for instructions on how to
program the coded key.
Note: The SecuriLock passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note: Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition to the off position, remove
all objects on the key chain away from the coded key and restart the
engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.

Anti-theft indicator

The anti-theft indicator is the flashing red indicator located on the dash
panel.
• When the ignition is in the off position, the indicator will flash once
every two seconds to indicate the SecuriLock system is functioning
as a theft deterrent.
• When the ignition is in the on position, the indicator will glow for
three seconds to indicate normal system functionality.
If a problem occurs with the SecuriLock system, the indicator will flash
rapidly or glow steadily when the ignition is in the on position. If this
occurs, contact your authorized dealer as soon as possible for service.
Automatic arming
The vehicle is armed immediately after switching the ignition to the off
position.
The theft indicator on the instrument panel will flash every two seconds
when the vehicle is armed.
