Hello all. I am new to the site. I purchased a 2010 F-250 this weekend and am going nuts with the seatbelt chiming! I have seen some forums for escapes and others but none for the F250 - any ideas on how to disable it?
Thanks in advance for your help!

 

Welcome to the site..

Preparation

The Belt-minder can also be deactivated/activated using a scan tool.

Before deactivating/activating the Belt-Minder, apply the parking brake.
Place the gearshift in the PARK position (automatic transmission) or the NEUTRAL position (manual transmission).
Place the ignition switch in the OFF position.
Close all the vehicle doors.
Unbuckle the driver safety belt.
Place the headlamp switch in the OFF position.

Deactivating/Activating

Turn the ignition switch to the RUN position (don't start the engine).
Wait until the safety belt warning indicator turns off after approximately 1 minute.
Step 3 must be completed within 50 seconds after the safety belt warning indicator turns off.

At a moderate rate, buckle then unbuckle the driver safety belt 9 times, ending with the safety belt in the unbuckled state.
After this step, the safety belt warning indicator illuminates for 3 seconds.
The buckle/unbuckle sequence may not be counted if completed too fast. Wait approximately 2 seconds after each sequence.

Within 10 seconds after the safety belt warning indicator turns off, buckle then unbuckle the safety belt.
This disables the Belt-Minder feature, if it is currently enabled. As confirmation, the safety belt warning indicator flashes 4 times per second for 3 seconds.
This enables the Belt-Minder feature, if it is currently disabled. As confirmation, the safety belt warning indicator flashes 4 times per second for 3 seconds followed by another flash sequence of 4 times per second for 3 seconds.
After confirmation, the deactivation/activation procedure is complete.
