These models are equipped with a Supplemental Restraint System (SRS), commonly known as an airbag system, featuring at least two airbags for the driver and front seat passenger, designed to protect occupants from serious injury during a head-on or frontal collision. The airbag control module is situated on the transmission tunnel beneath the center of the instrument panel, with some models offering optional side curtain airbags identifiable by the "SRS - AIRBAG" logo on the headliner above the B-pillar. The airbag module contains the airbag and inflater unit, which inflates the bag almost instantaneously upon receiving an electrical signal from the airbag control module via a "clockspring," a flat, ribbon-like electrically conductive tape. The passenger's airbag is located in the dashboard above the glove box, with an ON/OFF switch for deactivating it when transporting an infant or young child in a safety seat; removal of the airbag is not recommended unless it has been activated in an accident. Optional side-curtain airbags are positioned on each roof side rail and extend from the A-pillar to the C-pillar, and should only be removed if deployed in an accident. The Airbag Control Module (ACM) monitors the airbag system, illuminating an indicator light during startup to indicate proper operation; if a fault is detected, it stores a Diagnostic Trouble Code (DTC) and keeps the light on until repaired. The ACM controls standard driver and passenger airbags, while vehicles with side-curtain airbags also have Side Impact Airbag Control Modules (SIACMs) located behind the B-pillar trim. When servicing components near the SRS system, it is crucial to disable the system to prevent accidental deployment, which involves turning off the ignition, disconnecting the negative battery terminal, and waiting at least two minutes. To enable the system, the ignition should be turned off, the negative battery terminal reconnected, and the ignition turned on while ensuring no body is in front of the airbags, checking that the indicator light functions correctly. The front passenger's seat includes a weight sensor module as part of the Occupant Classification System (OCS), which is critical for airbag deployment; if the seat is removed, no one should sit in it until the airbag and OCS have been verified by a dealer service department to prevent serious injury or death in an accident.
