Supplementary Restraints System
RESTRAINT SAFETY SYSTEM
The Restraint Safety 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 Safety System consists of:
• Driver and passenger dual-stage airbag supplemental restraints.
• Front outboard safety belts with pretensioners, energy management
retractors (first row only), and safety belt usage sensors.
• Driver's seat position sensor.
• Front crash severity sensors.
• Restraints control module with impact and safing sensors.
• Restraint system warning light and backup 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 Safety System work?
The Restraint Safety 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. During a crash, the
restraints control module 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.
SOS POST-CRASH ALERT SYSTEM™
The system flashes the turn signal lamps and sounds the horn
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle, such as front, side, side curtain or Safety Canopy.
The horn and lamps will turn off when:
• You press the hazard control button.
• You press the panic button (if equipped) on the remote entry transmitter.
• Your vehicle runs out of power.
