GMC 2004 Canyon - Manual (Page 75)

In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
• Air bags are designed to inflate only once. After an
air bag inflates, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
• Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. If your vehicle has side impact air bags,
it also has electronic side sensors. Your vehicle is
equipped with a crash sensing and diagnostic
module, which records information about the air bag
system. The module records information about
the readiness of the system and when the system
commands air bag inflation. It records the status of
the driver’s safety belt usage in a crash in which
the air bag deploys or a crash in which the air bag
nearly deploys. The module also records speed,
engine rpm, brake and throttle data.
• Let only qualified technicians work on your air bag
system. Improper service can mean that your air
bag system will not work properly. See your dealer
for service.
Notice: If you damage the covering for the driver’s
or the right front passenger’s air bag, or the side
impact air bag covering on the ceiling near the side
windows, the bag may not work properly. You may
have to replace the air bag module in the steering
wheel, both the air bag module and the instrument
panel for the right front passenger’s air bag, or
side impact air bag module and ceiling covering
for the roof-mounted side impact air bag. Do not
open or break the air bag coverings.
