Dear Pontiac Owner:
This notification is being sent to all 1982 Pontiac T1000 owners in the State of California.
The General Motors Maintenance Schedule for 1982 Gasoline-Fueled Passenger Cars equipped with automatic transmission specifies replacement of the oxygen sensor at 30,000 miles. This statement is in error and this maintenance requirement does not apply to 1982 T1000 models equipped with the California emissions option.
The Maintenance Schedule also refers to an emissions flag which will appear on the odometer face to alert the owner to the need for changing the oxygen sensor. Your vehicle should not have been assembled with that flag since, as noted above, the oxygen sensor on 1982 Pontiac T1000 models equipped with the California emissions option need not be replaced. Inadvertently, however, some 1982 T1000 models were built with an emission flag which will appear in the speedometer face at each 30,000 mile interval. Should an emissions flag appear on your car's speedometer, please make an appointment with your dealer for correction. Resetting the flag takes less than one-half hour and will be performed at no charge to you.
Please keep this notification in your car with your maintenance folder and leave it with the car when sold.
We have taken this action in the interest of continued customer satisfaction.
