Supplementary Restraints SystemCRASH SENSORS ANDAIRBAG INDICATORWARNINGModifying or adding equipment tothe front end of the vehicle (includingframe, bumper, front end bodystructure and tow hooks) may affect theperformance of the airbag system,increasing the risk of injury. Do not modifythe front end of the vehicle.Your vehicle has a collection of crash andoccupant sensors which provideinformation to the restraints controlmodule which deploys (activates) thefront safety belt pretensioners, driverairbag, passenger airbag, seat mountedside airbags, and the Safety Canopy®.Based on the type of crash (frontal impact,side impact or rollover), the restraintscontrol module will deploy the appropriatesafety devices.The restraints control module alsomonitors the readiness of the above safetydevices plus the crash and occupantsensors. The readiness of the safetysystem is indicated by a warning indicatorlight in the instrument cluster or by abackup tone if the warning light is notworking. See Instrument Cluster (page81). Routine maintenance of the airbag isnot required.A difficulty with the system is indicated byone or more of the following:The readiness light will notilluminate immediately after theignition is turned on.• The readiness light will either flash orstay lit.• A series of five beeps will be heard. Thetone pattern will repeat periodicallyuntil the 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.The fact that the safety belt pretensionersor front airbags did not activate for bothfront seat occupants in a crash does notmean that something is wrong with thesystem. Rather, it means the restraintscontrol module determined the accidentconditions (crash severity, belt usage)were not appropriate to activate thesesafety devices.• The design of the front airbags is toactivate only in frontal and near-frontalcrashes (not rollovers, side impacts orrear impacts) unless the crash causessufficient frontal deceleration.• The design of the safety beltpretensioners is to activate in frontal,near-frontal and side crashes, and inrollovers.• The design of the side airbags is toinflate in certain side impact crashes.Side airbags may activate in othertypes of crashes if the vehicleexperiences sufficient sideways motionor deformation.• The design of the Safety Canopy is toinflate in certain side impact crashesor rollover events. The Safety Canopymay activate in other types of crashesif the vehicle experiences sufficientsideways motion or deformation, or acertain likelihood of rollover.AIRBAG DISPOSALContact your authorized dealer as soon aspossible.
