Supplementary Restraints SystemE67017

WARNING: Do not attempt to service,repair, or modify the supplementaryrestraint system or associated components.Failure to follow this instruction could resultin personal injury or death.
WARNING: If a supplementaryrestraint system component has deployed,it will not function again. Have the systemand associated components inspected assoon as possible. Failure to follow thisinstruction could result in personal injuryor death.
The side airbags are on the outermost sideof the seat backrests of the front seats. Theairbag was designed to inflate between thedoor panel and occupant to further enhancethe protection provided occupants in sideimpact crashes.
The system consists of the following:
•A label or embossed side panelindicating that side airbags are found onyour vehicle.
•Side airbags inside the seat backrest ofthe driver and front passenger seats.
•Front passenger sensing system.
·Crash sensors and monitoringsystem with readiness indicator.See Crash Sensors and AirbagIndicator (page 59).
The design and development of the sideairbag system included recommendedtesting procedures that were developed bya group of automotive safety experts knownas the Side Airbag Technical Working Group.These recommended testing procedureshelp reduce the risk of injuries related to thedeployment of side airbags.
SAFETY CANOPY™
WARNING: Do not place objects ormount equipment on or near the headlinerat the siderail that may come into contactwith a deploying curtain airbag. Failure tofollow these instructions may increase therisk of personal injury in the event of acrash.
WARNING: Do not lean your headon the door. The curtain airbag could injureyou as it deploys from the headliner.

Supplementary Restraints SystemE152533 E67017

WARNING: Do not attempt to service,repair, or modify the supplementaryrestraint system or associated components.Failure to follow this instruction could resultin personal injury or death.
WARNING: All occupants of yourvehicle, including the driver, should alwaysproperly wear their seatbelts, even whenan airbag supplemental restraint system isprovided. Failure to properly wear yourseatbelt could seriously increase the riskof injury or death.
WARNING: To reduce risk of injury,do not obstruct or place objects in thedeployment path of the airbag.
WARNING: If a supplementaryrestraint system component has deployed,it will not function again. Have the systemand associated components inspected assoon as possible. Failure to follow thisinstruction could result in personal injuryor death.
The Safety Canopy deploys during significantside crashes or when a certain likelihood ofa rollover event is detected by the rolloversensor. The Safety Canopy is mounted tothe roof side rail sheet metal, behind theheadliner, above each row of seats. In certainsideways crashes or rollover events, theSafety Canopy will be activated, regardlessof which seats are occupied. The SafetyCanopy is designed to inflate between theside window area and occupants to furtherenhance protection provided in side impactcrashes and rollover events.
The system consists of the following:
•Safety Canopy curtain airbags above thetrim panels over the front and rear sidewindows identified by a label or wordingon the headliner or roof-pillar trim.
•A flexible headliner which opens abovethe side doors to allow air curtaindeployment
· Crash sensors and monitoringsystem with a readiness indicator.See Crash Sensors and AirbagIndicator (page 59).
Properly restrain children 12 years old andunder in the rear seats. The Safety Canopywill not interfere with children restrainedusing a properly installed child or boosterseat because it is designed to inflatedownward from the headliner above thedoors along the side window opening.

CRASH SENSORS AND AIRBAG
INDICATOR
WARNING: Modifying or addingequipment to the front end of your vehicle(including hood, bumper system, frame,front end body structure, tow hooks andhood pins) may affect the performance ofthe airbag system, increasing the risk ofinjury. Do not modify or add equipment tothe front end of your vehicle.
Your vehicle has a collection of crash andoccupant sensors which provide informationto the restraints control module whichdeploys (activates) the front seatbeltpretensioners, driver airbag, passengerairbag, rear inflatable belts, seat mountedside airbags, and the Safety Canopy. Basedon the type of crash, the restraints controlmodule will deploy the appropriate safetydevices.
The restraints control module also monitorsthe readiness of the above safety devicesplus the crash and occupant sensors. Thereadiness of the safety system is indicatedby a warning indicator light in the instrumentcluster or by a backup tone if the warninglight is not working. See Instrument Cluster(page 113). Routine maintenance of theairbag is not required.
A difficulty with the system is indicated byone or more of the following:
The readiness light will notilluminate immediately after youswitch the ignition on.
•The readiness light either flashes or stayslit.
•A series of five beeps will be heard. Thetone pattern will repeat periodically untilthe problem, the light or both arerepaired.
If any of these things happen, evenintermittently, have the supplementalrestraint system serviced at an authorizeddealer immediately. Unless serviced, thesystem may not function properly in theevent of a crash.
