Safety Belt Reminder Light When the key is turned to RUN or START, a chime will come on for several seconds to remind people to fasten their safety belts. The safety belt light will also come on and stay on for several seconds. If the driver's belt is already buckled, neither the chime nor the light will come on. Passenger Safety Belt Reminder Light Several seconds after the key is turned to RUN or START, a chime will be provided for several seconds to remind the front passenger to buckle their safety belt. This would only occur if a passenger is detected by the passenger sensing system. See Passenger Sensing System on page 1-66 for more information. The passenger safety belt light will also be provided and stay on for several seconds, then it will flash for several more. You should have the passenger buckle their safety belt. This chime and light will be repeated if the passenger remains unbuckled and the vehicle is in motion. If the passenger's safety belt is buckled, neither the chime nor the light will be provided. 3-37
