There are four warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and
lamp), key-in-ignition (chime only), and driver seat belt warning (chime and lamp).
When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The safety belt warning indicator lamp will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the
same time.
If the safety belt is buckled while the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the ignition switch is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will
remain activated until either the timing sequence has been executed or the safety belt is buckled.
