Mistake: Using LATCH (lower anchors and tethers for children) restraint system incorrectly.
Why: Not using the top tether will allow the child's head to experience excessive forward movement in crashes. Using LATCH centered in the rear seat could cause it to work improperly.
What to do: Ensure LATCH works in the seat position you've chosen and that the top tether is tightened snugly.
