Seat Cushion - Front, Passenger Side: Disassembly

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
CAUTION: It is necessary to carry out the occupant classification sensor (OCS) system reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command. Failure to follow this instruction may result in system failure and the incorrect operation of the OCS system.
CAUTION: Do not install a new heater mat on a front passenger seat cushion, it is not serviceable separately. If a new cushion heater mat is needed on the front passenger seat, an occupant classification sensor (OCS) system service kit equipped with a heater mat must be installed. Failure to follow this instruction may result in incorrect operation of the OCS system. Refer to SUPPLEMENTAL RESTRAINT SYSTEM article for the OCS removal and installation procedure.
NOTE: Occupant classification sensor (OCS) system components (seat wiring harness, seat cushion foam pad, bladder with pressure sensor and occupant classification system module [OCSM]) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system, OCS system component or seat cushion foam pad are needed, an OCS system service kit (seat cushion foam pad, bladder with pressure sensor, seat wiring harness and OCSM) must be installed as an assembly.
NOTE: To identify between a production OCS system and a OCS system service kit, inspect the OCSM electrical connector. 

A production OCS system allows the disconnection of the OCSM electrical connector.

An OCS system service kit has the electrical connector glued to the module, it cannot and should not be disconnected or altered.

NOTE: The air bag warning indicator illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    WARNING: Install a new occupant classification sensor (OCS) system service kit as a complete assembly. Never install only part of the kit components. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.
    NOTE: To identify between a production OCS system and a OCS system service kit, inspect the OCSM electrical connector. 

    A production OCS system allows the disconnection of the OCSM electrical connector.

    An OCS system service kit has the electrical connector glued to the module. It cannot and should not be disconnected or altered.
