RESTRAINTSDESCRIPTION
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 second row seating. An upper tether anchor is integral to the back of the left and right outboard seat back panels, and one is integral to the cushion frame of the center seat section. Two lower anchors are also provided for each outboard seating position. The lower anchors are integral to the seat cushion frame and are accessed from the front of the second row 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 a 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. Both front seat belt buckles include an integral Hall-effect seat belt switch that detects whether the front seat belts have been fastened.
- Second Row Seat Belts - All three second row 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 and fixed lower seat belt anchors secured to the rear floor panel by fasteners shared with the second seat latch striker bracket. The second row seat center seating position has an inertia latch-type emergency locking retractor that is secured within the seat back to the second row center seat back frame. All of the second row seat belt retractors for this vehicle are also switchable from an emergency locking retractor to an automatic locking retractor for compatibility with child seats. The center seating position belt lower anchor is secured to the right center seat support bracket along with the right outboard seat belt buckle. All three second row seat belts have fixed end-release seat belt buckles secured to the center seat cushion frame. A single buckle unit on the right side of the center seat section and a double buckle unit on the left.
- Third Row Seat Belts - Both third row seating positions are equipped with three-point seat belt systems. The third row seating positions have inertia latch-type emergency locking retractors that are secured within the seat back to the third row seat back frames. Both third row seat belt retractors for this vehicle are also switchable from an emergency locking retractor to an automatic locking retractor for compatibility with child seats. The third row seating position belt lower anchors are secured to the outboard rear corners of the third row seat support bracket. Both third row seat belts have fixed end-release seat belt buckles secured to a shared bracket on the third row seat support bracket between the rear inboard corners of the two seat cushions.
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 is a passive, inflatable, Supplemental Restraint System (SRS) and vehicles with this equipment can be readily identified by the "SRS - AIRBAG" logo molded into the driver air-bag 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) 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.
- Occupant Classification System - Vehicles manufactured for sale in North America (except Mexico) also include an Occupant Classification System (OCS) with components that are located on the front seats. These components include an Occupant Classification Module (OCM) and four seat weight sensors on the passenger seat, and seat track position sensors on both the driver and passenger front seats. Vehicles equipped with the OCS components can be readily identified by a passenger airbag on/off indicator (3) located on the right end of the upper switch pod (2) near the top of the instrument panel lower center bezel (1).
- Side Curtain Airbags - Side curtain airbags are standard equipment in this vehicle when it is also equipped with dual front airbags. This airbag system is a passive, inflatable, Supplemental Restraint System (SRS) 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 the top of each B-pillar upper trim.
The supplemental restraint system includes the following major components, which are described in further detail:
- Airbag Indicator - The airbag indicator is integral to the Electromechanical Instrument Cluster (EMIC), which is located on the instrument panel in front of the driver.
- Clockspring - The clockspring is integral to the Steering Control Module (SCM) located near the top of the steering column, directly beneath the steering wheel.
- Driver Airbag (4) - 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 Classification Module (5) - Vehicles equipped with the Occupant Classification System (OCS) include an Occupant Classification Module (OCM) which is secured to the seat riser frame under the passenger side front seat cushion.
- Occupant Restraint Controller (6) - 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 Airbag On/Off Indicator (3) - The Occupant Classification System (OCS) includes a passenger airbag on/off indicator which is located in the upper switch pod near the top of the instrument panel lower center bezel.
- 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 (10) - 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 (8) - The Occupant Classification System (OCS) includes two seat track position sensors. One sensor is located on the inboard side of one of the seat adjuster tracks on both the driver and the passenger front seats.
- Seat Weight Sensor (7) - Vehicles equipped with the Occupant Classification System (OCS) include four seat weight sensors, one on each corner of the passenger side front seat between the seat riser frame and the seat track.
- Side Curtain Airbag (11) - A side curtain airbag is secured to each inside roof side rail, and extends from the A-pillar to just ahead of the D-pillar. The side curtain airbags are concealed above the headliner trim.
- Side Impact Sensor (9) - Six side impact sensors are used on this vehicle, three on each side of the vehicle. One sensor is located behind the B-pillar trim near the belt line of each B-pillar, one sensor is located behind the quarter panel trim near the belt line of each C-pillar, and one sensor is located behind the quarter panel trim near the belt line of each quarter inner panel just forward of the D-pillar.
The ORC, the OCM, 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.
Hard wired circuitry connects the supplemental restraint system 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 supplemental restraint system 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.
