# OXYGEN SENSOR MAINTENANCE EMISSION REMINDER FLAG

All 1981 T1000's require an oxygen sensor change at 30,000 mile intervals as indicated in Section "C" of the Vehicle Maintenance Schedule. The cost of this maintenace is to be assumed by the owner.

On these vehicles, an "Emission" reminder flag will appear in a window in the speedometer face at 30,000 mile intervals. When this flag appears the oxygen sensor should be replaced and the reminder flag reset.

The emission flag resetting procedure is detailed in the following illustration:

To avoid early deployment of the flag (and to avoid causing a "comeback"), it is important to feel 3 clicks or detents of the flag wheel.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
