Emissions Maintenance Reminder Light



The light uses a time measuring module which relies upon ignition on-time as a basis to calculate maintenance intervals. When the interval has elapsed, the light will come illuminate until the module is reset. To do this press the reset switch by inserting a small rod into the hole in the module. The module is located behind the far right side of the instrument panel, next to the glove box.
