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. This incompatibility may result in these vehicles failing the test even though they are operating properly and have passed the factory emissions test.
Saturn will keep you informed of any new developments. If you have any questions, please contact the AET Information Center at (313) 357-5108.
Sincerely,
Customer & Retail Support Operations

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.

The Auto Exhaust Testing vision has granted a one-year "AET Testing Exemption' to all 1991 and later model Year Saturn motor vehicles. The exemption is effective from March 1, 1993, through February 28, 1994.
According to information published by the Environmental Protection Agency, a design characteristic makes these vehicles incompatible with Michigan's current idle test. The vehicles may fail the emission test even though they are operating exactly as designed and manufactured.
Owners of these vehicles have been notified that an AET test is not required in order to register their vehicles with the Secretary of State during the period of exemption.
Effective May 1, 1993, AET waivers will be extended for one year for approximately 8,000 pattern failure vehicles. These vehicles can be identified by matching their vehicle identification numbers (VINs) with the characters listed in the chart below:
AET WAIVER ELIGIBILITY VIN CHARACTER POSITION ---------------------- ---------------------- Vehicle Year Vehicle Make 2 3 4 5 6 7 8 10 ------------ ------------ ----------------------------------------- 1984 Ford Bronco II F M U 1 4 S E 1984 Honda Prelude H A B E 1985 Honda Prelude H A B F
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.
