RAM Chassis CAB 2018, Owner'S Manual, Page: 226 / 527

Any seat belt system will loosen with time, so check the
belt occasionally, and pull it tight if necessary.
If the buckle or the cinching latch plate is too close to the
belt path opening of the child restraint, you may have
trouble tightening the seat belt. If this happens, disconnect
the latch plate from the buckle and twist the short buckle-
end belt up to three full turns to shorten it. Insert the latch
plate into the buckle with the release button facing out,
away from the child restraint. Repeat steps 4 to 6, above, to
complete the installation of the child restraint.
If the belt still cannot be tightened after you shorten the
buckle, disconnect the latch plate from the buckle, turn the
buckle around one half turn, and insert the latch plate into
the buckle again. If you still cannot make the child restraint
installation tight, try a different seating position.
Installing Child Restraints Using The Top Tether
Anchorage
WARNING!
Do not attach a tether strap for a rear-facing car seat to
any location in front of the car seat, including the seat
frame or a tether anchorage. Only attach the tether
strap of a rear-facing car seat to the tether anchorage
that is approved for that seating position, located
behind the top of the vehicle seat. See the section
“Lower Anchors and Tethers for CHildren (LATCH)
Restraint System” for the location of approved tether
anchorages in your vehicle.
