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 direction indicator lamps and the horn sounds
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle.
The horn and lamps turn off when:
• You press the hazard button.
• You press the panic button (if equipped) on the remote entry
transmitter.
• Your vehicle runs out of power.
