Safety belt extension assembly
If the safety belt is too short when fully extended, a safety belt extension
assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

Belt-Minder
The Belt-Minder feature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders to the
driver that the driver's safety belt is unbuckled by intermittently
sounding a chime and illuminating the safety belt warning lamp in the
instrument cluster.
When the Belt-Minder feature is activated, the safety belt warning light
illuminates and the warning chime sounds for 6 seconds every
30 seconds, repeating for approximately 5 minutes or until the safety
belts are buckled.
Note: If you are using MyKey , the Belt-Minder warning will not
expire. Refer to MyKey in the Locks and security chapter.
