GMC 2007 Envoy Denali Owner's Manual page 87

CAUTION:
{
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system.
If this ever happens, have the vehicle
serviced promptly, because an
adult-size person sitting in the right
front passenger's seat may not have
the protection of the frontal airbag.
See Airbag Readiness Light on page 201
for more on this, including important
safety information.
Aftermarket equipment, such as seat covers, can
affect how well the passenger sensing system
operates. You may want to consider not using
seat covers or other aftermarket equipment if
your vehicle has the passenger sensing system.
See Adding Equipment to Your Airbag-Equipped
Vehicle on page 89 for more information about
modifications that can affect how the system
operates.
CAUTION:
{
Stowing of articles under the passenger's
seat or between the passenger's seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
