Seating and Safety Restraints Conditions of operation If...The driver's safety belt is not buckled before the ignition switch is turned to the on position...The driver's safety belt is buckled while the indicator light is illuminated and the warning chime is sounding...The driver's safety belt is buckled before the ignition switch is turned to the on position...Belt-Minder The Belt-Minder 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 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. Then...The safety belt warning light illuminates 1-2 minutes and the warning chime sounds 4-8 seconds. The safety belt warning light and warning chime turn off. The safety belt warning light and indicator chime will remain off. 125
