Chevrolet Pontiac Wave 2007 Owner's Manual page 84

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 airbag and side
impact airbag (if equipped), 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 airbag for that person.
If a person of adult-size is sitting in the right front
passenger's seat, but the off symbol is lit, it
could be because that person is not sitting properly
in the seat. If this happens do the following:
Turn the vehicle off and ask the person to place
the seatback in the fully upright position, then
sit upright in the seat, centered on the seat
cushion, with the person's legs comfortably
extended. Restart the vehicle and have the person
remain in this position for about two minutes.
This will allow the system to detect that person and
then enable the passenger's airbag or airbags.
