104 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
8. If the child restraint has a top tether strap and the
seating position has a top tether anchorage, connect
the tether strap to the anchorage and tighten the tether
strap. See the section "Installing Child Restraints
Using the Top Tether Anchorage" for directions to
attach a tether anchor.
9. Test that the child restraint is installed tightly by
pulling back and forth on the child seat at the seat belt
path. It should not move more than 1 inch (25.4 mm)
in any direction.
Any seat belt system will loosen with time, so check the
seat belt occasionally, and pull it tight if necessary.
Installing Child Restraints Using the Top Tether
Anchorage
1. Look behind the seating position where you
plan to install the child restraint to find the
tether anchorage. You may need to move the
seat forward to provide better access to the
tether anchorage. If there is no top tether anchorage for
that seating position, move the child restraint to another
position in the vehicle if one is available.
2. To access the top tether strap anchorages behind the
rear seat, pull the carpeted floor panel away from the
seat back, this will expose the top tether strap anchor-
ages.
