To remove the child restraint, just unbuckle the vehicle's safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. If you were using a rear-facing child restraint in a regular cab model or a extended cab model, turn on the right front passenger's air bag when you remove the rear-facing child restraint from the vehicle unless the person who will be sitting there is a member of a 1Switch on passenger air bag risk group. See Air Bag 0 7 page 1-61. If the right front ssenger's air bag is turned off for a person who isn't in a risk group identified by the national government, that person won't have the extra protectionof an air bag. In a crash, the air bag wouldn't be able to inflate and help protect the person sitting there. Don't turn off the passenger's air bag unless the person sitting there is in a risk group. See "Air Bag Off Switch" in the Index for more on this, including important safety information. 1-54
