Service engine soon
Your vehicle is
equipped with a
computer that monitors
the engine's emission
control system. This
system is commonly known as the On Board
Diagnostics System (OBD II). The OBD II system
protects the environment by ensuring that your
vehicle continues to meet government emission
standards. The OBD II system also assists the
service technician in properly servicing your vehicle.

to check the bulb. If it comes on after the engine is
started, one of the engine's emission control systems
may be malfunctioning. The light may illuminate
without a driveability concern being noted. The
vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.
Temporary malfunctions may cause yourService
Engine Soonlight to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may
misfire or run poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed
and securely tightened.
These temporary malfunctions can be corrected by
filling the fuel tank with high quality fuel of the
recommended octane and/or properly installing and
securely tightening the gas cap. After three driving
cycles without these or any other temporary
malfunctions present, theService Engine Soonlight
should turn off. (A driving cycle consists of a cold
engine startup followed by mixed city/highway
driving.) No additional vehicle service is required.
If theService Engine Soonlight remains on, have
your vehicle serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occurring which could damage your
catalytic converter. You should drive in a moderate
fashion (avoid heavy acceleration and deceleration)
and have your vehicle serviced at the first available
opportunity.

Raising the convertible top
The convertible top will not operate unless the
parking brake is engaged. Do not raise the top while
the vehicle is moving because the top may be
severely damaged.
To raise the convertible top:
1. Bring the vehicle to a complete stop. Engage the
parking brake. Key must be in the ON position.
2. Remove the boot cover and store it in the luggage
compartment.
3. Lower the front and rear side windows.
4. Push the convertible top button, holding it until
the top unfolds and moves forward toward the
windshield header.
5. Open both top clamps before the top meets the
windshield header
6. Continue to use the top motor to raise the top
until it has reached the fully closed position flush to
the header.
7. The two pins under the forward edge of the top
should seat themselves in the matching holes in the
header.
8. To fasten both clamps securely, push the clamp
handles into the header on the top until they are
flush with the header. Pulling down on the header at
the center grip while closing the latches may assist
in fastening the clamps.
9. Raise the front and rear side windows.

SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
The SecuriLockypassive anti-theft system provides
an advanced level of vehicle theft protection. Your
vehicle's engine can only be started with the two
special SecuriLockyelectronically coded keys
provided with your vehicle. Each time you start your
vehicle, the SecuriLockykey is read by the
SecuriLockypassive anti-theft system. If the
SecuriLockykey identification code matches the
code stored in the SecuriLockyanti-theft system,
the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match
the code stored in the system or if a SecuriLocky
key is not detected (vehicle theft situation), the
vehicle's engine will not operate.
If there is any potential SecuriLockyanti-theft
problem with your vehicle, ensureALL
SecuriLockykeysfor that vehicle are brought to
the dealership, to aid in troubleshooting.
The SecuriLockypassive anti-theft system is not
compatible with aftermarket remote start systems.
Use of these systems may result in vehicle starting
problems and a loss of security protection. Large
metallic objects, a second key or electronic devices
Controls and features
57

used to purchase gasoline or similar items on the
same key ring as the PATS ignition key may cause
vehicle starting problems. If present, you need to
keep these objects from touching the PATS ignition
key while starting the engine. These objects cannot
damage the PATS ignition key, but can cause a
momentary problem if they are too close to the key
during engine start. If a problem occurs, turn the
ignition OFF and restart the engine with all other
objects on the key ring held away from the ignition
key. Check to make sure the encoded ignition key is
an approved Ford encoded ignition key.
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system. Refer to
Programming spare SecuriLockykeysfor more
information.
If one or both of your SecuriLockykeys are lost or
stolen and you want to ensure the lost or stolen key
will not operate your vehicle, bring your vehicle and
all available SecuriLockykeys to your dealership for
reinitialization.
Theft indicator
The theft indicator on the instrument cluster will
operate as follows:
²When the ignition is OFF, the theft indicator will
flash briefly every two seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²When the ignition is turned to ON or START, the
theft indicator will light for three seconds and
then go out. If the theft indicator stays on for an
extended period of time or flashes rapidly, have
the system serviced by your dealership or a
qualified technician.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system (up to a total
Controls and features
58

of eight keys). Your dealership can program your
new SecuriLockykey(s) to your vehicle or you can
do it yourself using the following simple procedure.
To program a new SecuriLockykey yourself, you
will need two previously programmed SecuriLocky
keys (keys that already operate your vehicle's
engine). If two previously programmed SecuriLocky
keys are not available (one or both of your original
keys were lost or stolen), you must bring your
vehicle to your dealership to have the spare
SecuriLockykey(s) programmed.
Procedure to program spare SecuriLockYkeys
to your vehicle
New SecuriLockykeys must have the correct
mechanical key cut for your vehicle.
Conventional (non-SecuriLocky) keyscannotbe
programmed to your vehicle.
You will need to have two previously programmed
SecuriLockykeys and the new unprogrammed
SecuriLockykey readily accessible for the
procedure. Please read and understand the entire
procedure before you begin.
1. Insert the first previously programmed
SecuriLockykey into the ignition and turn the
ignition from OFF to ON (maintain ignition in ON
for at least one second).
2. Turn ignition to OFF and remove the first
SecuriLockykey from the ignition.
3. Within five seconds of turning the ignition to OFF,
insert the second previously programmed
SecuriLockykey into the ignition and turn the
ignition from OFF to ON (maintain ignition in ON
for at least one second but no more than five
seconds).
4. Turn the ignition to OFF and remove the second
SecuriLockykey from the ignition.
5. Within 10 seconds of turning the ignition to OFF,
insert the unprogrammed SecuriLockykey (new
Controls and features
59

key/valet key) into the ignition and turn the ignition
from OFF to ON (maintain ignition in ON for at least
one second). This step will program your new
SecuriLockykey.
6. To program additional SecuriLockykey(s), repeat
this procedure from step 1.
If the programming procedure was successful, the
new SecuriLockykey(s) will start the vehicle's
engine. The theft indicator (located on the
instrument cluster) will light for three seconds and
then go out.
If the programming procedure was not successful,
the new SecuriLockykey(s) will not operate the
vehicle's engine. The theft indicator will flash on and
off. Wait at least one minute and then repeat the
procedure from step 1. If failure repeats, bring your
vehicle to your dealership to have the spare
SecuriLockykey(s) programmed.
