If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

From the F-150 Forums, since I just bought one and this worked!

This is straight from my 2009 f150 owners guide

Preperation
1. the parking brake is set
2. truck in park
3. ignition switch is in off position
4. both seat belts are unbuckled

Disable Belt-Minder
1. turn the ignition switch to the on position, DO NOT START THE ENGINE.
2. wait until the safety belt warning light turns off. (approximately 1 minute).
* step 3 must be completed within 50 secs after the safety belt warning light turns off.
3. buckle then unbuckle the seat belt nine times, ending in the seat belt unbuckled.
* after step 3 the restraint warning light, (airbag light) will turn on for three (3) seconds.
4. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
* the restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation

you can do this for the passenger side also!!!


*NOTE
in step 3. after three times buckling and unbuckling the restraint warning light lit up in my truck. SO I WENT TO THE NEXT STEP, (STEP 4). waited 3 seconds and i buckled and unbuckled.

in the buckle /unbuckle procedure do it some what slowly and watch for the light. it may not take 9 times.

DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
