Ford 2010 Mariner Owner's Manual page 513

The Belt-Minder feature uses information from the front passenger
sensing system to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
Belt-Minder feature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the front passenger sensing system.
Both the driver's and passenger's safety belt usages are monitored and
either may activate the Belt-Minder feature. The warnings are the same
for the driver and the front passenger. If the Belt-Minder warnings have
expired (warnings for approximately five minutes) for one occupant
(driver or front passenger), the other occupant can still activate the
Belt-Minder feature.
Note: If you are using MyKey™, the Belt-Minder warning will not
expire. Refer to MyKey™ in the Locks and security chapter.
