A thick layer of additional material, such as a blanket
or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM
for your specific vehicle. See Adding Equipment to
Your Airbag-Equipped Vehicle on page 2 74 for more
information about modifications that can affect how the
system operates.
A wet seat can affect the performance of the passenger
sensing system. Here is how:
The passenger sensing system may turn off the
passenger airbag when liquid is soaked into the
seat. If this happens, the off indicator will be lit,
and the airbag readiness light on the instrument
panel will also be lit.
Liquid pooled on the seat that has not soaked
in may make it more likely that the passenger
sensing system will enable (turn on) the passenger
airbag while a child restraint or child occupant is on
the seat. If the passenger airbag is turned on, the
on indicator will be lit.
If the passenger seat gets wet, dry the seat
immediately. If the airbag readiness light is lit, do
not install a child restraint or allow anyone to occupy
the seat. See Airbag Readiness Light on page 4 26
for important safety information.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat. If this
is not desired, remove the object from the seat.
WARNING:
Stowing of articles under the passenger seat
or between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.
