Chevrolet 2003 Silverado 1500 Pickup Owner's Manual page 537

Even though the passenger sensing system is
designed to turn off the passenger's frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy
under some unusual circumstance, even
though it is turned off. General Motors,
therefore, recommends that rear-facing child
restraints be secured in the rear seat whenever
~
possible, even if the air bag is off.
The passenger sensing system
is
designed to turn off
the right front passenger's frontal air bag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
the system determines that a small child is present
rear-facing infant seat
in a forward-facing child restraint
the system determines that a small child is present
in a booster seat
a right front passenger takes hislher weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the air bag
system or the passenger sensing system.
For
some
children who have outgrown child restraints
and for
very
small adults, the passenger sensing system
may
or
may not turn off the right front passenger's
frontal air bag, depending upon the person's seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear a safety
belt properly
-
whether or not there is an air bag
for that person.
