GMC 2008 Acadia - Manual (Page 77)

Remove any additional material from the seat such as
blankets, cushions, seat covers, seat heaters, or
seat massagers before reinstalling or securing the child
restraint.
If 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/retailer.
The passenger sensing system is designed to enable
(may inflate) the right front passenger’s frontal
airbag and seat-mounted side impact airbag 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 airbags to be
enabled, the on indicator will light and stay lit to
remind you that the airbags are 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
airbag and seat-mounted side impact airbag, 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 indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off, remove any additional
material from the seat, such as blankets, cushions,
seat covers, seat heaters or seat massagers 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 two to three minutes. This will allow the
system to detect that person and then enable the
right front passenger’s frontal airbag and seat-mounted
side impact airbag.
