After the vehicle has been operated for 30,000 miles the oxygen sensor warning light located on the instrument panel will come on, indicating that the oxygen sensor should be checked.
After verifying oxygen sensor operation, turn off the warning light by resetting the hold relay located behind the right side kick panel, Fig. 3b. After the 90,000 mile service, reset the lamp so it does not come again by disconnecting the warning light electrical connector, Fig. 3.
