THESE DEALER LISTINGS MAY CONTAIN CUSTOMER NAMES AND ADDRESSES OBTAINED FROM STATE MOTOR VEHICLE REGISTRATION RECORDS. THE USE OF SUCH MOTOR VEHICLE REGISTRATION DATA FOR ANY OTHER PURPOSE IS A VIOLATION OF LAW IN SEVERAL STATES. ACCORDINGLY, YOU ARE URGED TO LIMIT THE USE OF THIS LISTING TO THE FOLLOW-UP NECESSARY TO COMPLETE THIS CAMPAIGN.

#### NOTICE: DUE TO THE SMALL NUMBER OF VEHICLES INVOLVED AND DUE TO LIMITED INITIAL PARTS AVAILABILITY, DEALERS ARE ENCOURAGED NOT TO ORDER CAMPAIGN PARTS FOR USE AS SHELF STOCK. PARTS SHOULD ONLY BE ORDERED WHEN INSPECTION DETERMINES THAT IT IS NECESSARY TO REPLACE THE IGNITION CONTROL MODULE.

#### NOTICE: IT IS ESTIMATED THAT ONLY 17% OF INVOLVED VEHICLES WILL REQUIRE IGNITION CONTROL MODULE REPLACEMENT. PLEASE ORDER PARTS ACCORDINGLY.

CUSTOMER NOTIFICATION

CUSTOMERS WILL BE NOTIFIED OF THIS CAMPAIGN ON THEIR VEHICLES BY GENERAL MOTORS (SEE COPY OF TYPICAL CUSTOMER LETTER INCLUDED WITH THIS BULLETIN - ACTUAL DIVISIONAL LETTER MAY VARY SLIGHTLY).

IN ORDER TO ENSURE FULL PROTECTION UNDER THE EMISSION WARRANTY, AND THE RIGHT TO PARTICIPATE IN FUTURE RECALLS, THE CUSTOMER NOTIFICATION LETTER RECOMMENDS THAT CUSTOMERS HAVE THEIR VEHICLES SERVICED AS SOON AS POSSIBLE. IT ALSO ADVISES THAT FAILURE TO DO SO COULD LEGALLY BE DETERMINED TO BE LACK OF PROPER MAINTENANCE. THE VEHICLE MAY FAIL A STATE OR LOCAL EMISSION INSPECTION TEST IF THE RECALL WORK IS NOT COMPLETED.

DEALER CAMPAIGN RESPONSIBILITY

ALL UNSOLD NEW VEHICLES IN DEALERS' POSSESSION AND SUBJECT TO THIS CAMPAIGN MUST BE HELD AND INSPECTED/REPAIRED PER THE SERVICE PROCEDURE OF THIS CAMPAIGN BULLETIN BEFORE CUSTOMERS TAKE POSSESSION OF THESE VEHICLES.

ARRANGEMENTS ARE TO BE MADE TO MAKE THE REQUIRED CORRECTION ACCORDING TO THE INSTRUCTIONS CONTAINED IN THIS BULLETIN. THIS COULD BE DONE BY MAILING TO SUCH CUSTOMERS A COPY OF THE APPROPRIATE DIVISIONAL LETTER. CAMPAIGN FOLLOW-UP CARDS SHOULD NOT BE USED FOR THIS PURPOSE, SINCE THE CUSTOMER MAY NOT AS YET HAVE RECEIVED THE NOTIFICATION LETTER.

IN SUMMARY, WHENEVER A VEHICLE SUBJECT TO THIS CAMPAIGN ENTERS YOUR VEHICLE INVENTORY, OR IS IN YOUR DEALERSHIP FOR SERVICE IN THE FUTURE, PLEASE TAKE THE STEPS NECESSARY TO BE SURE THE CAMPAIGN CORRECTION HAS BEEN MADE BEFORE SELLING OR RELEASING THE VEHICLE.
