2006 GMC Sierra 1500 Pickup Owner's Manual - Page 66

{CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the passenger's airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Do not use a rear-facing child restraint in this vehicle unless the passenger's airbag has been turned off. United States Canada Even though the airbag off switch is designed to turn off the passenger's frontal airbag, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be transported in vehicles with a rear seat that will accommodate a rear-facing child restraint, whenever possible. If you need to secure a forward-facing child restraint in the right front static seat or the right front bench seat, always move the passenger seat as far back as it will go. Your switch may vary slightly. See Airbag Off Switch on page 1-78 for more on this, including important safety information and illustrations of alternate switch designs. 1-60
