This message continues to display for two seconds if it has not been acknowledged when the engine is turned off. It also re-displays for two seconds if the message has been acknowledged, but the condition still exists when the engine is turned off. If the condition still exists, the message re-appears when the engine is turned on. PASSENGER SEATBELT IS NOT FASTENED This message reminds you to buckle the passenger's safety belt. This message displays and a chime sounds when the ignition is on, the driver's safety belt is buckled, the passenger's safety belt is unbuckled with the passenger airbag enabled, and the vehicle is in motion. You should have the passenger buckle their safety belt. The reminder will be repeated if the ignition is on, the vehicle is in motion, the driver is unbuckled and the passenger is still unbuckled and the passenger airbag is enabled. If the passenger's safety belt is already buckled, this message and chime will not come on. 240
