FLEXIBLE SYSTEM SERVICE (FSS) INDICATOR
Flexible System Service (FSS) indicator will appear as a wrench symbol in the odometer display area. This indicates either 30 days or 2000 miles until the next suggested vehicle service should be performed. Intervals between suggested service are set for either 10,000 or 20,000 miles/365 or 730 days. FSS display can be recalled for 10 seconds by pressing the dimmer/trip odometer reset knob 2 times. If suggested service interval is passed, wrench symbol will be displayed along with a minus sign that blinks.
After service is performed, the FSS indicator will need to be reset.
