GMC Sierra 2005 Owner's Manual page 78

Child age 1 to 12. A child age 1 to 12 must
ride in the front seat because:
•
my vehicle has no rear seat;
•
although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space
is available in the rear seat(s) of my vehicle; or
•
the child has a medical condition which, according
to the child's physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child's condition.
Medical Condition. A passenger has a
medical condition which, according to his or
her physician:
•
causes the passenger airbag to pose a special risk
for the passenger; and
•
makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.

CAUTION:
{
If the right front passenger's airbag is turned
off for a person who is not in a risk group
identified by the national government, that
person will not have the extra protection of
an airbag. In a crash, the airbag will not be
able to inflate and help protect the person
sitting there. Do not turn off the passenger's
airbag unless the person sitting there is in a
risk group.
