Dodge 2009 Nitro - Manual (Page 76)

If the belt still can’t be tightened, or if by pulling and
pushing on the restraint loosens the belt, you may need
to do something more. Disconnect the latch plate from
the buckle, turn the buckle around, and insert the latch
plate into the buckle again. If you still can’t make the
child restraint secure, try a different seating position.
To attach a child restraint tether strap:
Route the tether strap over the seatback and attach the
hook to the tether anchor located on the back of the seat.
For the outboard seating positions, route the tether under
the head rests, and attach the hook to the tether anchor
located on the back of the seat.
WARNING!
An incorrectly anchored tether strap could lead to in-
creased head motion and possible injury to the child.
Use only the anchor positions directly behind the child
seat to secure a child restraint top tether strap.
