WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The Inflatable Restraints Passenger Presence System (PPS) is a calibrated system that requires rezeroing anytime the seat cushion trim attachments have been removed or the PPS has been replaced. The procedures below are designed to assist in the rezeroing of the PPS. Before you start, read these procedures carefully and completely. For further information regarding the PPS refer to SIR System Description and Operation .

IMPORTANT: The following procedures must be followed:
  1. Read this procedure carefully and completely.
  2. The PPS will not function properly if the PPS rezeroing procedure is not performed.
  3. Perform the Diagnostic System Check - Vehicle (without HP2) or Diagnostic System Check - Vehicle (with HP2) after successfully completing the rezeroing procedure to ensure the system is functioning properly.
