Seating and Safety Restraints
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.
When the Belt-Minder feature is activated, the safety belt warning light
illuminates and the warning chime sounds for six seconds every
30 seconds, repeating for approximately five minutes or until the safety
belts are buckled.
The Belt-Minder feature uses two different warning chimes. During the
first minute of activation, the warning chime will sound once every
second. The remaining warning chimes will sound twice every second
while the system is activated.
