Supplementary Restraints System CRASH SENSORS AND AIRBAG INDICATOR 55 WARNING: Modifying or adding equipment to the front end of your vehicle (including frame, bumper, front end body structure and tow hooks) may affect the performance of the airbag system, increasing the risk of injury. Do not modify the front end of your vehicle. Your vehicle has a collection of crash and occupant sensors which provide information to the restraints control module which deploys (activates) the front safety belt pretensioners, driver airbag, passenger airbag, seat mounted side airbags, and the Safety Canopy. Based on the type of accident (frontal impact, side impact or rollover) 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 indicator light in the instrument cluster or by a backup tone if the warning light is not working. See the Instrument Cluster chapter. Routine maintenance of the airbag is not required. A difficulty with the system is indicated by one or more of the following: • The readiness light will either flash or stay lit. • The readiness light will not illuminate immediately after the ignition is turned on. • A series of five beeps will be heard. The tone pattern will repeat periodically until the problem or light are repaired. If any of these things happen, even intermittently, have the supplemental restraint system serviced at an authorized dealer immediately. Unless serviced, the system may not function properly in the event of a crash. 2013 C-Max Full Hybrid (34h) Owners Guide gf, 3rd Printing, January 2013 USA (fus)
