How do I disarm the seat belt chime, on my 2011 f150

 

From the owners manual


WARNING:While the design allows you to deactivate your
Belt-Minder, this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Mindersystem activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minderfeature while driving the vehicle

One time disable
If at any time the driver/front passenger quickly buckles then unbuckles
the Belt-Minderfeature for that seating position, the Belt-Minder™ is
disabled for the current ignition cycle. The Belt-Minderfeature will
re-enable during the same ignition cycle if the occupant buckles and
remains buckled for approximately 30 seconds. Confirmation is not given
for the one time disable.

The following instructions are to disable the feature until it is re-enabled.

Read Steps1-4thoroughly before proceeding with the
deactivation/activation programming procedure.

Note:If you are using MyKey, the Belt-Minder cannot be disabled.

Also, if the Belt-Minder has been previously disabled, it will be
re-enabled after the use of MyKey. Refer to MyKey in the Locks and
security chapter.

The driver and front passenger Belt-Minderfeatures can be
deactivated/activated by performing the following procedure:
Before following the procedure, make sure that:
•The parking brake is set
•The gearshift is in P (Park)
•The ignition switch is in the off position
•The driver and front passenger safety belts are unbuckled

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 one
minute)
•Step 3 must be completed within 30 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, buckle then unbuckle the
safety belt three times, ending in the unbuckled state.
•After Step 3, the restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds.

If the seat is in a disabled setting:

•This will enable the Belt-Minderfeature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds, followed by
three seconds with the light off, then followed by the restraint system
warning light flashing four times per second for three seconds again.

 

Nice post Shorebird!...I agree with leaving the chime on!

 

Does this also apply to a 99 F250 SD?
