SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine immobilization
system. This system is designed to prevent the engine from being started
unless acoded key programmed to your vehicleis used.
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.
THEFT INDICATOR
The theft indicator is the flashing red indicator located on the dash
panel.
•When the ignition is in the 1 (OFF/LOCK) position, the indicator will
flash once every 2 seconds to indicate the SecuriLock
system is
functioning as a theft deterrent.
•When the ignition is in the 3 (ON) position, the indicator will glow for
3 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 3 (ON) position. If
this occurs, the vehicle should be taken to an authorized dealer for
service.

Automatic arming
The vehicle is armed immediately
after switching the ignition to the 3
(OFF) or 2 (LOCK) position. The
indicator on the instrument panel
will flash every two seconds when
the vehicle is armed.
Automatic disarming
Switching the ignition to the 4 (ON) position with acoded keydisarms
the vehicle. The indicator on the instrument will illuminate for three
seconds and then go out. If the indicator stays on for an extended period
of time or flashes rapidly, have the system serviced by your dealership or
a qualified technician.
Key information
Your vehicle is supplied withtwo coded keys (or three, if your
vehicle is equipped with the valet feature).Only acoded keywill
start your vehicle. Spare coded keys can be purchased from your
dealership. Your dealership can program your key or you can“do it
yourself.”Refer to theProgramming spare keyssection in this chapter.
The following items may prevent the vehicle from starting:
•Large metallic objects
•Electronic devices on the key chain that can be used to purchase
gasoline or similar items
•A second key on the same key ring as thecoded key
If any of these items are present, you need to keep these objects from
touching thecoded keywhile starting the engine. These objects and
devices cannot damage thecoded key,but can cause a momentary“no
start”condition if they are too close to the key during engine start. If a
problem occurs, turn the ignition to the OFF position and restart the
engine with all other objects on the key ring held away from the ignition
key. Check to make sure thecoded keyis an approved Mercurycoded
key.

If your keys are lost or stolen you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a dealership or a locksmith. The key codes
will need to be erased from your vehicle and new key codes will need
to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a“no start”condition.
If an unprogrammed key is used in the ignition it will cause a“no
start”condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock
keys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
programmedcoded keyinto the
ignition and turn the ignition from 3
(OFF) to 4 (ON) (maintain ignition
in 4 (ON) for at least one second).
2. Turn ignition to 3 (OFF) then 2
(LOCK) and remove the firstcoded
keyfrom the ignition.
3. Within ten seconds of removing
the firstcoded key,insert the
second previously programmedcoded keyinto the ignition and turn the
ignition from 3 (OFF) to 4 (ON) (maintain ignition in 4 (ON) for at least
one second but no more than ten seconds).
4. Turn the ignition to 3 (OFF) then 2 (LOCK) and remove the second
coded keyfrom the ignition.

5. Within twenty seconds of removing the secondcoded key,insert the
new unprogrammed key (new key) into the ignition and turn the ignition
from 3 (OFF) to 4 (ON) (maintain ignition in 4 (ON) for at least one
second). This step will program your new key.
6. To program additional new unprogrammed key(s), wait at least 20
seconds and repeat this procedure from Step 1.
If successful, the new coded key(s) will start the vehicle’s engine and the
theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle’s engine
and the theft indicator will flash on and off. You may repeat Steps 1
through 6. If failure repeats, bring your vehicle to your dealership to
have the new spare key(s) programmed.

STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks automatic
transmission gearshift lever and
allows key removal.
3. OFF, shuts off the engine and all
accessories without locking the
steering wheel. This position also allows the automatic transmission shift
lever to be moved from the P (Park) position without the brake pedal
being depressed.
When the key is in the ignition and in the OFF position, the
automatic transmission shift lever can be moved from the P
(Park) position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.

Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
1. Turn the key to 4 (ON) without
turning the key to 5 (START).
2. Turn the key to 5 (START), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -10°F (-23°C) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.

•The anti-lock system does not reduce stopping distance. Always leave
enough room between your vehicle and the vehicle in front of you to
stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If the light does not
illuminate momentarily at start up,
remains on or continues to flash, the ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Parking brake with auto-release (if equipped)
Apply the parking brake whenever
the vehicle is parked.
To set the parking brake:
1. Move the gearshift to P (Park).
2. Push pedal downward.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is fully released.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
