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). SeePassenger Sensing
System on page 1-63.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check that the safety belt reminder
light, safety belts, buckles, latch plates, retractors,
and anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired.
Torn or frayed safety belts may not protect you
in a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-27for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-85.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-28for more information.
Notice: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 covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-61. See your dealer/retailer
for service.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced.
If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was not being
used at the time of the crash.
If an airbag in ates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the vehicle
has been in a crash, if the airbag readiness light stays
on after the vehicle is started, or while you are driving.
SeeAirbag Readiness Light on page 3-28.
