Where to Put the Restraint (Regular Cab and Extended Cab Pickup) The child restraint must be secured properly in the right front passenger seat. If you want to secure a rear-facing child restraint in the right front passenger's seat, turn off the passenger's air bag. See Air Bag Off Switch on page 1-61 and Securing a Child Restraint in the Right Front Seat Position on page 1-49 for more on this, including important safety information. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger's air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. Even though the AIR BAG OFF switch is designed to turnoff the passenger's frontal air bag, no system is fail-safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though is it turned off. General Motors therefore recommends that rear-facing child restraints be transported in vehicles with a rear seat that will accommodate a rear-facing child restraint, whenever possible. 1-40
