GMC 2003 Yukon Owner's Manual page 89

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
rear-facing infant seat
•
the system determines that a small child is present
in a forward-facing child restraint
•
the system determines that a small child is present
in a booster seat
•
a right front passenger takes his/her 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.
When the passenger sensing system has turned off the
passenger's frontal air bag, the off indicator will light
and stay lit to remind you that the air bag is off.
The passenger sensing system is designed to turn off
the passenger's frontal air bag when a rear facing infant
seat, a forward-facing child restraint or a booster seat
is detected. If the child restraint has been installed
and the on indicator is lit, turn the vehicle off, remove
the child restraint from the vehicle and reinstall the
restraint following the child restraint manufacturer's
directions and refer to Securing a Child Restraint in the
Right Front Seat Position on page 1-66 of this manual.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, secure the child in
the child restraint in a rear seat position in the vehicle
and check with your dealer.
The passenger sensing system is designed to enable
(may inflate) the right front passenger's frontal air
bag anytime the system senses that a person of adult
size is sitting properly in the right front passenger's seat.
When the passenger sensing system has allowed the
air bag to be enabled, the on indicator will light and stay
lit to remind you that the air bag is active.
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.
