Using the Safety Belt with Cinch Tongue (Front and Rear Center
Seat)
The cinch tongue slides up and down the belt webbing when the belt is
stowed or while putting safety belts on. When the lap and shoulder
safety belt is buckled, the cinch tongue allows the lap portion to be
shortened, but pinches the webbing to keep the lap portion from getting
longer. The cinch tongue is designed to slip during a crash, so always
wear the shoulder belt properly and do not allow any slack in either the
lap or shoulder portions.
Before you can reach and latch a lap and shoulder belt having a cinch
tongue into the buckle, you may have to lengthen the lap belt portion
of it.

1. To lengthen the lap belt,
pull some webbing out of the
shoulder belt retractor.
2. While holding the webbing
below the tongue, grasp the tip
(metal portion) of the tongue so
that it is parallel to the webbing
and slide the tongue upward.
3. Provide enough lap belt length
so that the tongue can reach the
buckle.
