system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualified to
do so.
Adding Equipment to the
Airbag-Equipped Vehicle
{Warning
If a snow plow or similar equipment is
installed on the vehicle, the airbag
system may not function properly. An
airbag could inflate when it is not
supposed to inflate. People riding in the
vehicle could be injured, and the vehicle
and/or snow plow could be damaged. Do
not install a snow plow or similar
equipment on the vehicle.
Adding accessories that change the vehicle's
frame, bumper system, height, front end,
or side sheet metal may keep the airbag
system from working properly.
The operation of the airbag system can also
be affected by changing any parts of the
front seats, seat belts, airbag sensing and diagnostic module, steering wheel,
instrument panel, inner door seals including
the speakers, any of the airbag modules,
ceiling or pillar garnish trim, overhead
console, front sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module, and
airbag wiring.
In addition, the vehicle has a passenger
sensing system for the front outboard
passenger position, which includes sensors
that are part of the passenger seat. The
passenger sensing system may not operate
properly if the original seat trim is replaced
with non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any object,
such as an aftermarket seat heater or a
comfort-enhancing pad or device, installed
under or on top of the seat fabric, could
also interfere with the operation of the
passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing
system from properly turning off the
passenger airbag(s). See
Passenger Sensing
System 039. If the vehicle has rollover roof-rail airbags,
see
Different Size Tires and Wheels 0281 for
additional important information.
If the vehicle must be modified because you
have a disability and have questions about
whether the modifications will affect the
vehicle's airbag system, or if you have
questions about whether the airbag system
will be affected if the vehicle is modified for
any other reason, call Customer Assistance.
See Customer Assistance Offices 0330.Airbag System Check
The airbag system does not need regularly
scheduled maintenance or replacement.
Make sure the airbag readiness light is
working. See Airbag Readiness Light 085.
Caution
If an airbag covering is damaged, opened,
or broken, the airbag may not work
properly. Do not open or break the airbag
coverings. If there are any opened or
broken airbag coverings, have the airbag
covering and/or airbag module replaced.
For the location of the airbags, see Where
Are the Airbags? 036. See your dealer
for service.
