See Lower Anchors and Tethers for Children (LATCH) on page 2‑49 for more information. 8. Push and pull the child restraint in different directions to be sure it is secure. If the vehicle is equipped with a passenger sensing system, and when the passenger sensing system has turned off the right front passenger frontal airbag, the off indicator in the passenger airbag status indicator should light and stay lit when you start the vehicle. If a child restraint has been installed and the on indicator is lit, see "If the On Indicator is Lit for a Child Restraint" under Passenger Sensing System on page 2‑86 for more information. To remove the child restraint, unbuckle the vehicle safety belt and let it return to the stowed position. If the top tether is attached to a top tether anchor, disconnect it. 6. To tighten the belt, push down on the child restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor. When installing a forward-facing child restraint, it may be helpful to use your knee to push down on the child restraint as you tighten the belt. 2-65
