Supplemental Inflatable Restraint Disabling & Enabling Zones

WARNING: This page does not describe the selected car, but rather 63 other vehicles, including the 2004 Suzuki Swift +, 2004 Pontiac Vibe, 2004 Pontiac Sunfire, 2004 Pontiac Montana, and 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Not all zones are used by all vehicles.

The Supplemental Inflatable Restraint (SIR) system has been divided into disabling and enabling zones. When performing service on or near SIR components or SIR wiring, it may be necessary to disable the SIR components in that zone. It may be necessary to disable more than one zone depending on the location of other SIR components and the area being serviced. See Fig 1 . Identify the specific zone or zones in which service will be performed and disable and enable selected zone or zones.
