OCCUPANT RESTRAINT SYSTEMS ROLL SENSING OF CURTAIN SHIELD AIRBAGS OFF SWITCH In a severe side impact, the curtain shield airbags on impacted side will inflate even if the roll sensing function is turned off. (For details about the curtain shield airbags, see "SRS side airbags and curtain shield airbags" on page 179.) In a severe frontal impact, the seat belt pretensioners will work even if the roll sensing function is turned off. (For details about the seat belt pretensioners, see "Seat belt pretensioners" on page 162.) If the ignition switch is turned to "ACC" or "LOCK" with the roll sensing function off and then the ignition switch is turned back to "ON", the roll sensing function will turn back on automatically. The roll sensing of curtain shield airbags off switch ("RSCA OFF" switch) can turn off the curtain shield airbags and seat belt pretensioners in a vehicle rollover. This switch should only be used if inflation is not desired (such as extreme off-road driving). When you push the "RSCA OFF" switch for a few seconds with the ignition switch on, the "RSCA OFF" indicator light comes on and the roll sensing function is turned off. When you push the switch again, the indicator light goes off and the roll sensing function is turned on. (For details about the roll sensing function, see "SRS side airbags and curtain shield airbags" on page 179.) CAUTION D Before normal driving, make sure the "RSCA OFF" indicator light is off. D When the roll sensing function is turned off (and the "RSCA OFF" indicator light is on), the curtain shield airbags and seat belt pretensioners will not work in a vehicle rollover. Turning off the curtain shield airbags and seat belt pretensioners reduces occupant protection which your vehicle safety systems can provide in accidents and increase the likelihood of death or serious injuries. 199
