FORD MUSTANG 1999 4.G Repair Manual

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 or devices such as the Mobil
Speedpassyon the same key ring as your
SecuriLockykey may cause vehicle starting
problems. These objects and devices cannot damage
the SecuriLockykey, but can cause a momentary
problem if they are too close to the key when
starting the engine. If a problem occurs, turn
ignition off and restart the engine with all other
objects on the key ring held away from the
SecuriLockyignition 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.

operate as follows:
²When the ignition is OFF, the theft indicator will
flash briefly every 2 seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²When the ignition is turned to RUN or START, the
theft indicator will light for 3 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
of 8 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 SecuriLockykeys
(keys that already operate your vehicle's engine). If
two previously programmed SecuriLockykeys 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 RUN (maintain ignition in RUN
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 RUN (maintain ignition in RUN
for at least one second but no more than 5 seconds).

5. Within 10 seconds of turning the ignition to OFF,
insert the unprogrammed SecuriLockykey (new
key/valet key) into the ignition and turn the ignition
from OFF to RUN (maintain ignition in RUN 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.

It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not allow
people to ride in any area of your vehicle that is
not equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
Each seating position in your vehicle has a
specific safety belt assembly which is made
up of one buckle and one tongue that are designed
to be used as a pair. 1) Use the shoulder belt on
the outside shoulder only. Never wear the shoulder
belt under the arm. 2) Never swing the safety belt
around your neck over the inside shoulder. 3)
Never use a single belt for more than one person.
Always transport children 12 years old and
under in the back seat and always properly
use appropriate child restraints.
Combination lap and shoulder belts
Before fastening the
safety belt, make sure
the shoulder belt
passes through the belt

The front and rear outboard safety restraints in the
vehicle are combination lap and shoulder belts. The
front passenger and rear seat outboard safety belts
have two types of locking modes described below:
Vehicle sensitive mode
The vehicle sensitive mode is the normal retractor
mode, allowing free shoulder belt length adjustment
to your movements and locking in response to
vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle
receives an impact of 8 km/h (5 mph) or more, the
combination safety belts will lock to help reduce
forward movement of the driver and passengers.
The seat belt system can also be made to lock
manually by quickly pulling on the shoulder belt.
Automatic locking mode
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove any
slack in the shoulder belt.
