Is it safe to put a rear-facing child restraint in the front passenger seat?

General Motors recommends that rear-facing child restraints never be placed in the right front passenger seat because the inflating airbag could seriously injure or kill the child. Even though the passenger sensing system is designed to turn off the front passenger airbag under certain conditions, no system is fail-safe. Always secure rear-facing child restraints in a rear seat whenever possible. (Page 68-69)
