Seating and Safety Restraints • seat-mounted side airbags. Refer to Seat-mounted side airbag system later in this chapter • Safety Canopy system. Refer to Safety Canopy system later in this chapter. • one or more impact and safing sensors. • Safety belt pretensioners • a readiness light and tone. • diagnostic module. • and the electrical wiring which connects the components. • Front passenger sensing system. Refer to Front passenger sensing system later in this chapter. • "Passenger airbag off" or "pass airbag off" indicator lamp. Refer to Front passenger sensing system later in this chapter. The RCM (restraints control module) monitors its own internal circuits and the supplemental airbag electrical system wiring (including the impact sensors, the system wiring, the airbag system readiness light, the airbag back up power and the airbag ignitors). WARNING: Several air bag system components get hot after inflation. Do not touch them after inflation. WARNING: If the airbag has deployed, the airbag will not function again and must be replaced immediately. If the airbag is not replaced, the unrepaired area will increase the risk of injury in a collision. Front passenger sensing system The front passenger sensing system is designed to meet the regulatory requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208 and is designed to disable (will not inflate) the front passenger's frontal airbag under certain conditions. The front passenger sensing system works with sensors that are part of the front passenger's seat and safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front passenger's frontal airbag should be enabled (may inflate) or disabled (will not inflate). 129 2009 Mariner (mrn) Owners Guide, 2nd Printing USA (fus)
