SAFETY RESTRAINTS
The restraint system provides an improved overall level of frontal crash
protection to front seat occupants and is designed to help further reduce
the risk of airbag-related injuries. The system is able to analyze different
occupant conditions and crash severity before activating the appropriate
safety devices to help better protect a range of occupants in a variety of
frontal crash situations.
Your vehicle’s restraint system consists of:
• Driver and passenger dual-stage airbag supplemental restraints.
• Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
• Driver’s seat position sensor.
• Front crash severity sensor.
• Restraints Control Module (RCM).
• Restraint system warning light and back-up tone.
• The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights.
How does the restraint system work?
The restraint system can adapt the deployment strategy of your vehicle’s
safety devices according to crash severity and occupant conditions. A
collection of crash and occupant sensors provides information to the
Restraints Control Module (RCM). During a crash, the RCM may activate
the safety belt pretensioners and/or either one or both stages of the
dual-stage airbag supplemental restraints based on crash severity and
occupant conditions.
The fact that the pretensioners or airbags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the restraint system determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front airbags are designed
to activate only in frontal and near-frontal collisions, not rollovers,
side-impacts, or rear-impacts unless the collision causes sufficient
longitudinal deceleration.
