If the air bag readiness lightever comes on when you have turnedoff the air bag, it means that something may be wrong with the air bag system. The right front passenger's air bag could inflate even though the switch isoff. If this ever happens, don't let anyone whom the national government has identifiedas a member of a passenger air bag risk group sit in the right front passenger's position (for example, don't secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. To turn off the right front passenger's air bag, insert your ignition key into the switch, push in, and move the switch to AIR BAG OFF. The AIR BAG OFF light will come on to let you know that the right front passenger's air bag is off. The right front passenger's air bag will remain off until you turn it back on again, and the AIR BAG OFF light will stay on to remind you that the air bag is off. 1-63
