Chevrolet 2009 Impala Owner's Manual page 71

The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
•
The right front passenger seat is unoccupied.
•
The system determines that an infant is present in
a child restraint.
•
A right front passenger takes his/her weight off of
the seat for a period of time.
•
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
See Passenger Airbag Status Indicator on page 3-29.
The passenger sensing system is designed to turn
on (may inflate) the right front passenger frontal airbag
anytime the system senses that a person of adult
size is sitting properly in the right front passenger seat.
When the passenger sensing system has allowed
the airbag to be enabled, the on indicator will light and
stay lit to remind you that the airbag is active.
For some children, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person's seating
posture and body build. Everyone in the vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for that
person.
CAUTION:
{
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See Airbag Readiness Light on page 3-28
for more information, including important safety
information.
