104 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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 ap-
proved tether anchorages in your vehicle.
