    CAUTION: If installing a new cushion foam pad, the heated seat element cannot be reused. A new cushion foam pad and cushion heated seat element must be used.
    CAUTION: Remove the paper strip covering the adhesive before adhering the heated seat element to the foam pad. Otherwise damage to the seat can occur.

    1. Position the trim cover to the cushion foam pad.
    2. Install the hog rings.
      • If equipped with heated seats, make sure the hog rings attaching the foam pad (at the wire anchors) and cushion trim cover are also attached through the windows at the edge of the heated seat element.

  11. Install the seat. For additional information, refer to SEAT - FRONT .
  12. Repower the SRS. Do not prove out the SRS at this time.  For additional information, refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .

    13. Passenger seat only 

    WARNING: Do not separate components.
    CAUTION: It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed, or an OCS service kit is installed. A diagnostic tool is used to trigger the active command to carry out rezeroing of the OCS system.
    CAUTION: Make sure the seat is completely assembled before rezeroing.
    CAUTION: The following precautions must be taken before rezeroing the OCS system:
    • Make sure the OCS system components are connected and no faults are present.
    • Make sure the OCS system is not at a temperature below 0°C (32°F) or above 45°C (113°F) when initiating the rezeroing process. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept at a temperature within the limits, 0°C to 45°C (32°F to 113°F) for a minimum of 30 minutes.
    • Make sure nothing is present on the passenger seat before rezeroing and nothing is placed on the seat during the rezeroing process.
    • Make sure a minimum 8 second time period has passed after cycling the ignition switch ON before the rezeroing process.
    NOTE: For best results in rezeroing, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
    NOTE: If the first attempt to rezero the OCS system is unsuccessful, a second attempt must be made.
  13. Rezero the occupant classification sensor.
    • With the front passenger seat empty, use a diagnostic tool to trigger the active command and rezero the occupant classification sensor.
    14. NOTE: The ignition switch must be cycled after rezeroing the OCS system.
  14. Cycle the ignition switch from ON to OFF.

    15. All seats 

  15. Prove out the supplemental restraint system (SRS) as follows:

    Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will:

    • fail to light.
    • remain lit continuously.
    • flash.

    The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired.

    Clear all continuous DTCs from the restraints control module using a diagnostic tool.
