#### To: All Saturn Retailers and General Managers in Michigan

The Michigan Department of State (Bureau of Automotive Regulation) has given notice that Saturn has been granted a one year "Auto Exhaust Testing (AET) Exemption" for all 1991 and later model year motor vehicles, The exemption is effective from March 1, 1993, through February 28, 1994. Attached you will find the AET bulletin explaining the testing exemption and the owner letter sent to Saturn owners of record. For a technical explanation of this issue please refer to Saturn Technical Information Bulletin 92-T-28A dated December, 1992.

In granting the exemption, the Bureau of Automotive Regulation cited a U.S. Enviromental Protection Agency report regarding a design characteristic of these vehicles resulting in incompatibility with the idle test.

Sample Exemption Letter:

Dear Vehicle Owner:

Your vehicle, which is described above, has been identified by the U.S. Environmental Protection Agency as having a design feature which may prevent it from being tested fairly under the Auto Exhaust Testing (AET) program required for residents of Wayne, Oakland and Macomb counties.

This notice is a temporary one-year waiver from auto exhaust testing through the date shown above. During this time, you are not required to obtain an emissions test for this vehicle before buying your license plate or tab.

We are working with the U.S. Environmental Protection Agency and your vehicle's manufacturer to make changes that will permit your vehicle to be tested fairly. If these changes cannot be made in the next year, you will receive another temporary waiver.

PLEASE RETAIN THIS NOTICE AND PRESENT IT WHEN YOU REGISTER THIS VEHICLE AT A SECRETARY OF STATE BRANCH OFFICE OR INCLUDE IT WITH YOUR RENEWAL NOTICE IF YOU CHOOSE TO RENEW YOUR LICENSE PLATE BY MAIL

If you transfer ownership of this vehicle, please give this waiver to the new owner. If you have already had this vehicle tested, unfortunately no refund is available.

If you have questions concerning this waiver, call the AET Information Center at 313/569-5080.

#### 1991 AND NEWER SATURN VEHICLES EXEMPT FROM AET TEST

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.
