Electronic Cluster (If Equipped)
The Electronic Cluster works only when your ignition is in the
ON position. Each time you start your vehicle, the displays go
through a self-test by lighting up all segments for about one
second and then turning off all segments for about one second,
before displaying actual gauge readings. (The turn signal and
high beam indicators do not light during the self-test. The LOW
OIL light may remain on throughout the self-test and for several
seconds after normal readings are displayed.) This self-test
demonstrates that all of the display segments are working
properly.
The electronic cluster has three major functions to provide you
with information about your vehicle's operating status:
Warning and Indicator Lights
Electronic Gauges
The Fuel Computer
Warning and Indicator Lights
Safety Belt Warning Light and Chime
This warning light and chime remind you to fasten your safety
belt. The following conditions will take place:
If the driver does not fasten the safety belt before the
ignition is turned to ON, the chime will sound for four (4) to
eight (8) seconds and the light will illuminate for one (1) to
two (2) minutes, or until the safety belt is fastened.
If the driver fastens the safety belt before the ignition is
turned to ON, the chime will not sound and the light will
not illuminate.
If the safety belt is buckled while the light is on and the
chime is sounding, both the light and the chime turn off.
