Description







DESCRIPTION

An occupant restraint system is standard factory-installed safety equipment on this vehicle. Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints require no action by the vehicle occupants to be employed.

ACTIVE RESTRAINTS

The active restraints for this vehicle include:

- Child Restraint Anchors - All vehicles are equipped with three, fixed-position, child seat upper tether anchors for the rear seating. Two anchors are integral to the back of the left rear seat back panel, and one is integral to the right rear seat back panel. Two lower anchors are also provided for each rear outboard seating position. The lower anchors are integral to the rear seat back panel bracket on the rear floor panel and are accessed from the front of the rear seat where the seat back meets the seat cushion.
- Front Seat Belts - Both front seating positions are equipped with three-point seat belt systems employing lower B-pillar mounted inertia latch-type emergency locking retractors, height-adjustable upper B-pillar mounted turning loops, a traveling lower seat belt anchor secured to the outboard side of the seat frame, and a traveling end-release seat belt buckle secured to the inboard side of the seat frame. The driver side front seat belt buckle includes an integral Hall-effect seat belt switch that detects whether the driver side front seat belt has been fastened.
- Rear Seat Belts - All three rear seating positions are equipped with three-point seat belt systems. The outboard seating position belts employ lower C-pillar mounted inertia latch-type emergency locking retractors, fixed position upper C-pillar mounted turning loops, self-cinching latch plates for compatibility with child seats, and fixed lower seat belt anchors secured to the rear floor panel by fasteners shared with the rear seat back panel bracket. The rear seat center seating position has an inertia latch-type emergency locking retractor that is secured within the seat back to the rear seat back panel. The center retractor for this vehicle is switchable from an emergency locking retractor to an automatic locking retractor for compatibility with child seats. The center retractor also has a cable that connects to the seat back latch, which locks the retractor spool unless the seat back is fully latched. The rear seat center seating position belt lower anchor is secured to the rear floor panel with the left outboard seat belt buckle. All three rear seat belts have fixed end-release seat belt buckles secured to the rear floor panel by fasteners shared with the rear seat back panel bracket, a single buckle unit on the left side and a double buckle unit on the right side.

PASSIVE RESTRAINTS





The passive restraints available for this vehicle include the following:

- Dual Front Airbags - Multistage driver and front passenger airbags 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 driver airbag trim cover in the center of the steering wheel and also into the passenger airbag area of the instrument panel top pad above the glove box. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) for about seven seconds as a bulb test each time the ignition switch is turned to the ON position. A pyrotechnic-type seat belt tensioner is also integral to the front seat belt buckle units mounted on the inboard side of each front seat cushion frame to work in conjunction with the dual front airbags.
- Side Curtain Airbags - Side curtain airbags are standard equipment for this vehicle when it is also equipped with dual front airbags. This airbag system consists of passive, inflatable,SRS components and vehicles with this equipment can be readily identified by a molded identification trim button with the SRS - AIRBAG logo located on the headliner above each B and C-pillar.





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

- Airbag Indicator - The airbag indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), 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 (3) - The driver airbag is located in the center of the steering wheel, beneath the driver airbag trim cover.
- Driver Knee Blocker - The driver knee blocker is a structural unit secured to the back side of and integral to the instrument panel steering column opening cover.
- Front Impact Sensor (1) - 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 each vertical member of the radiator support.
- Occupant Restraint Controller (4) - The Occupant Restraint Controller (ORC) is located on a mount on the floor panel transmission tunnel behind the transmission gear selector, and is concealed below the center floor console.
- Passenger Airbag (2) - The passenger airbag is located in the instrument panel, beneath the instrument panel top pad and above the glove box on the passenger side of the vehicle.
- Passenger Knee Blocker - The passenger knee blocker is a structural reinforcement that is integral to and concealed within the glove box door.
- Seat Belt Tensioner (6) - A seat belt tensioner is integral to both front seat belt buckle units on vehicles equipped with dual front airbags. The seat belt buckle tensioner units are secured to the inboard side of the front seat cushion frames and concealed beneath the inboard seat cushion side shield trim.
- Seat Track Position Sensor - A seat track position sensor is located on the inboard side of one of the seat adjuster tracks on the driver side front seat on vehicles manufactured for domestic markets.
- Side Curtain Airbag (8) - Vehicles with this equipment have a side curtain airbag secured to each inside roof side rail above the headliner, which extends from the A-pillar to just beyond the C-pillar.
- Side Impact Sensor (7) - Four side impact sensors are used on vehicles equipped with the optional side curtain airbags, two on each side of the vehicle. One sensor is located behind the B-pillar trim near the base of each B-pillar, and one sensor is located behind the quarter panel trim near the base of each C-pillar.

The ORC and the EMIC each contain a microprocessor 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 EMIC. 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.
