DESCRIPTION
An occupant restraint system is standard factory-installed safety equipment on this model. Available occupant
restraints for this model 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 model include:
•
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. 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 out-
board 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 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.
•
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.
PASSIVE RESTRAINTS
The passive restraints available for this model include
the following:

•
Dual Front Airbags - Multistage driver and front
passenger airbags are used in this model. This
airbag system is a passive, inflatable, Supple-
mental 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 illumi-
nate 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 of each front seat cush-
ion 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 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 - Optional side curtain airbags are available for this model when it is also equipped with
dual front airbags. This airbag system is a passive, inflatable, Supplemental Restraint System (SRS) and vehi-
cles with this equipment can be readily identified by a molded identification trim button with the “SRS - AIR-
BAG” logo located on the headliner above each B-pillar.
