GMC Sierra Classic 2007 Owner's Manual page 75

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.
Even though the airbag off switch is
designed to turn off the passenger's
frontal airbag, no system is fail-safe, and
CAUTION: (Continued)
CAUTION: (Continued)
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 seat,
always move the passenger seat as far
back as it will go.
