Supplementary Restraints System

The design and development of the side curtain airbags included recommended testing procedures that were developed by a group of automotive safety experts known as the Side Airbag Technical Working Group. These recommended testing procedures help reduce the risk of injuries related to the deployment of side curtain airbags. CRASH SENSORS AND AIRBAG INDICATOR WARNING Do not modify the front end of your vehicle. Modifying or adding equipment to the front end of your vehicle, including frame, bumper, front end body structure or tow hooks, may affect the performance of the airbag system, increasing the risk of injury. Your vehicle has a collection of crash and occupant sensors. These provide information to the restraints control module which will deploy the front safety belt pretensioners, driver airbag, driver knee airbag, passenger airbag, seat mounted side airbags, and the side curtain airbags. Based on the type of crash, frontal impact or side impact, the restraints control module will deploy the appropriate safety devices. The restraints control module also monitors the readiness of the above safety devices plus the crash and occupant sensors. The readiness of the safety system is indicated by a warning lamp in the instrument cluster or by a backup tone if thewarning lamp is not working. Routine maintenance of the airbag is not required. A difficulty with the system is indicated by one or more of the following:

The lamp will not illuminate immediately when you switch the ignition on.

• The lampwill either flash or remain on. • A series of five beepswill be heard. The tone pattern will repeat periodically until the problem, the lamp or both are repaired. If any of these things happen, even intermittently, have the supplemental restraint systemchecked by an authorized dealer immediately. Unless serviced, the systemmay not function correctly in the event of a crash. The safety belt pretensioners and the front airbag supplemental restraint system are designed to deploy when your vehicle sustains longitudinal deceleration sufficient to cause the restraints control module to deploy a safety device. The fact that the safety belt pretensioners or front airbags did not deploy for both front seat occupants in a crash does not mean that something is wrong with the system. It means the restraints control module determined that the crash conditions were not appropriate to deploy these safety devices. • The design of the front airbags is to deploy only in frontal and near-frontal crashes (not rollovers, side impacts or rear impacts) unless the crash causes sufficient longitudinal deceleration. • The design of the safety belt pretensioners is to deploy in frontal and near-frontal crashes, and may also deploy when a side curtain airbag deploys.
