The passive restraints available for this vehicle include the following:

• Active Head Restraints  - Inertia activated Active Head Restraints (AHR) are standard equipment for both front seating positions in this vehicle.
• Dual Front Airbags  - A multistage Driver AirBag (DAB) and front Passenger AirBag (PAB) are used in this vehicle. This airbag system consists of passive, inflatable, Supplemental Restraint System (SRS) components and vehicles with this equipment can be readily identified by the SRS - AIRBAG  logo molded into the DAB trim cover in the center of the steering wheel and also into the PAB area on the top of the instrument panel above the glove box. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) from four to six seconds as a bulb test each time the status of the ignition switch transitions to On. Pyrotechnic-type driver and passenger front seat belt retractors and anchor buckle tensioners also work in conjunction with the dual front and side curtain airbags.
• Knee Airbags  - The front airbag system also includes driver and passenger front Knee AirBags (KAB) (also known as Inflatable Knee Blockers/IKB) that are located just below the lower instrument panel reinforcements. These airbags are also passive, inflatable, SRS components and vehicles with this equipment can be readily identified by the SRS - AIRBAG  logo molded into the instrument panel trim just above each airbag location.
• Front Seat Airbags  - Front seat integrated Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are standard equipment in these vehicles. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG  logo located on the outboard side of the front seat back trim cover.
• Rear Seat Airbags  - Rear seat integrated Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are optional equipment in these vehicles. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG  logo located on the outboard sides of the rear seat cushion trim cover.
• Side Curtain Airbags  - Side curtain airbags (also known as Side AirBag Inflatable Curtains/SABIC) are standard equipment in this vehicle. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a molded identification SRS - AIRBAG  logo located near the top of each B-pillar trim panel.

The SRS includes the following major components, which are described in further detail elsewhere in this service information:

• Active Head Restraints  - One Active Head Restraint (AHR) is located atop each front seat back unit.
• Airbag Indicator  - The airbag indicator is integral to the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC), which is located on the instrument panel in front of the driver.
• Clockspring  - The clockspring is located near the top of the steering column, directly beneath the steering wheel.
• Driver Airbag  - The Driver AirBag (DAB) is located in the center of the steering wheel, beneath the DAB trim cover.
• Front Impact Sensor  - Two front impact sensors are used on vehicles equipped with dual front airbags, one left side and one right side. One sensor is located on the back side of the Front End Module (FEM) carrier, just outboard of each side of the cooling module.
• Knee Airbags  - This vehicle is equipped with Knee AirBags (KAB) (also known as Inflatable Knee Blockers/IKB). The KAB are mounted below the lower instrument panel reinforcements on each side of the vehicle.
• Occupant Classification System  - Vehicles manufactured for domestic markets have a Occupant Classification System (OCS). The OCS includes a Seat Weight Sensor (SWS) bladder, a pressure hose and an Occupant Classification Module (OCM) integral to the calibrated passenger front seat cushion.
• Occupant Detection Sensor  - Vehicles manufactured for export markets have a Occupant Detection Sensor (ODS) located on the top of the seat cushion foam of the passenger side front seat.
• Occupant Restraint Controller  - The Occupant Restraint Controller (ORC) is located on the floor panel transmission tunnel, between the dash panel and the instrument panel center stack support.
• Passenger Airbag  - The Passenger AirBag (PAB) is located in the instrument panel, beneath the instrument panel cover and above the glove box on the passenger side of the vehicle.
• Front Seat Airbag  - A front Seat AirBag (SAB) (also known as pelvic and thoracic airbag) is secured to each outboard front seat back frame, where it is concealed beneath the seat back trim cover and foam.
• Rear Seat Airbag  - The optional rear Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are secured to each outboard end of the rear seat cushion pan, where they are concealed beneath the seat cushion trim cover and foam.
• Seat Belt Tensioner  - A seat belt tensioner is integral to both front seat belt retractors and both front seat belt anchor buckle units. The seat belt retractor tensioner units are secured to each lower inner B-pillar and are concealed behind the lower B-pillar trim. The seat belt anchor buckle tensioner units are located on the inner sill near the base of the B-pillar and are concealed behind the inner sill trim.
• Seat Track Position Sensor  - There are two Seat Track Position Sensors (STPS). One sensor is located on the inboard side of one of the seat adjuster tracks on both the driver and the passenger front seats.
• Side Curtain Airbag  - A standard equipment side curtain airbag (also known as a Side AirBag Inflatable Curtain/SABIC) is secured to each inside roof side rail above the headliner, and extends from the A-pillar to just beyond the C-pillar.
• Side Impact Sensor  - Six side impact sensors are used on vehicles equipped with side curtain airbags, three on each side of the vehicle. One acceleration-type sensor is located behind the B-pillar trim near the base of each B-pillar, and one acceleration-type sensor is located behind the quarter panel trim near the base of each C-pillar. One pressure-type sensor is located on each front poor hardware carrier panel, concealed behind each front door inside trim panel.

The ORC, the IPC and the OCM each contain a microcontroller and programming that allow them to communicate with each other using the Controller Area Network (CAN) data bus. This method of communication is used by the ORC for control of the airbag indicator in the IPC. Refer to COMMUNICATION, DESCRIPTION .

Hard wired circuitry connects the SRS components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system, and to the SRS components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.
