If the airbag is off, the off indicator in the passenger airbag status indicator will come on and stay on when the vehicle is started. If a child restraint has been installed and the on indicator is lit, turn the vehicle off. Remove the child restraint from the vehicle and reinstall the child restraint. If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, check to make sure that the vehicle's seatback is not pressing the child restraint into the seat cushion. If this happens, slightly recline the vehicle's seatback and adjust the seat cushion if possible. Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. 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. If you are using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 7. Push and pull the child restraint in different directions to be sure it is secure. Remove any additional material from the seat such as blankets, cushions, seat covers, seat heaters or seat massagers, before reinstalling or securing the child restraint. If the on indicator is still lit, secure the child in the child restraint in a rear seat position in the vehicle and check with your dealer/retailer. To remove the child restraint, unbuckle the vehicle's safety belt and let it go back all the way. 1-53
