Seating and Safety Restraints
BeltMinder
The BeltMinder feature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
light in the instrument cluster when the driver's and front passenger's
safety belt is unbuckled.
The BeltMinder 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
BeltMinder 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 BeltMinder feature. The warnings are the same
for the driver and the front passenger. If the BeltMinder warnings have
expired (warnings for approximately 5 minutes) for one occupant (driver
or front passenger), the other occupant can still activate the BeltMinder
feature.
