2005 GMC Canyon Owner's Manual - Page 56

Unless the right front passenger's frontal airbag has been turned off, never put a rear-facing child restraint in this vehicle. Here is why: {CAUTION: If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger's frontal airbag could inflate even though the switch is off. If this ever happens, do not let anyone whom the national government has identified as a member of a passenger airbag risk group sit in the right front passenger's position (for example, do not secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. See Airbag Off Switch on page 1-71. {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger's frontal 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 airbag has been turned off. Even though the airbag off switch is designed to turn off the right front 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. 1-50
