EMISSION CONTROL SYSTEMS WARRANTY POLICIES & PROCEDURES

Note: This bulletin supplements the information contained in the 1981 Service Policies and Procedures Manual on Emission Control Systems Warranties. Except for the information presented on "Dealer Certification" (item F, page 8), this bulletin pertains only to dealers in those states or jurisdictions which have established periodic vehicle inspection and maintenance (I/M) programs approved by the Environmental Protection Agency (EPA). The scope of the Performance Warranty is currently the subject of litigation with the EPA. As a result, the coverage of the warranty may be modified by the court's action. Cadillac reserves the right to change the terms of the warranty to be consistent with any action of the court. This bulletin should be filed with your 1981 Service Policies and Procedures Manual.

A. General Information

1981 vehicles are covered by two types of emission control systems warranties the Emission Components Defect Warranty and the Emission Performance Warranty. The Defect Warranty, which became effective with 1972 models, is a requirement of the Clean Air Act as amended in 1970. It applies to all car and truck models, and is covered in the 1981 Service Policies and Procedures Manual. The Performance Warranty is also a requirement of the Clean Air Act which recently has been implemented through regulations issued by the Environmental Protection Agency (EPA). It applies to all 1981 passenger cars and trucks operating in states or local jurisdictions with I/M programs as noted above.

B. Instructions to Owners on Emission Warranties

The Performance warranty statement along with the Components Defect Warranty is presented in the Cadillac Warranty Information folders provided to vehicle owners. In addition, the folders present important information (adjacent to the warranty statements) on replacement parts, maintenance service, parts coverage and claims procedure. Dealership personnel responsible for warranty administration should be familiar with the folder information, as well as the information contained in this bulletin.

C. Adjustments Under the Performance Warranty

The Performance warranty period is for 5 years or 50,000 miles, whichever occurs first. However, after the vehicle has been in operation for over 24 months or 24,000 miles, the repairs or replacements covered by the warranty are limited (by law) to only those components which were installed on or in a vehicle for the sole or primary purpose of reducing vehicle emissions and not in general use prior to model year 1968.

IN THOSE JURISDICTIONS WHERE IT IS APPLICABLE, THE PERFORMANCE WARRANTY MAY OVERLAP THE DEFECT WARRANTY. THIS COULD HAPPEN WHEN A LOCAL I/M TEST LEADS TO THE DISCOVERY OF A DEFECTIVE PART WHICH QUALIFIES FOR REPLACEMENT UNDER THE DEFECT WARRANTY. UNDER THESE CIRCUMSTANCES, THE WARRANTY COVERAGE WHICH IS BROADEST WILL APPLY.

Vehicles will be eligible for adjustments under the Performance Warranty only if all of the following conditions are met:

The vehicle has been maintained and operated in accordance with the instructions for proper maintenance and use set forth in the Owner's Manual, the Maintenance Schedule and the Warranty Information folder supplied with the vehicle;

The vehicle fails to conform for a period of 5 years or 50,000 miles, whichever occurs first, to the applicable emission standards of the U.S. Environmental Protection Agency, as judged by an EPA-approved I/M test; and

The failure to conform results or will result in the owner of the vehicle having to bear a penalty or other sanctions (including the denial of the right to use the vehicle) under local, state or federal law. EXCEPTION: This condition does not apply to a vehicle submitted for repair under the terms of the dealer certification procedure discussed under item F of this bulletin. The owner need not incur a penalty or sanction if his/her vehicle fails an EPA approved emission test within the 3 month/4,000 mile dealer certification period.

1. Procedure for Evaluating and Handling a Claim

The following procedure should be followed in evaluating a claim under the Performance Warranty:

(1) Ask the owner for evidence that the vehicle failed an I/M test and that he/she will bear a penalty or other sanction as a result.

(2) Determine if the vehicle is still under the 5 year/50,000 mile terms of the warranty.

(3) Check for reasonable evidence of vehicle maintenance. Refer to item C2, page 3, for information on evaluating maintenance.

(4) Determine the cause of the failure using the diagnostic information provided in the Cadillac Service Manual.

(5) Determine if the parts and/or labor-only operations required to repair the vehicle are covered under warranty by referring to item D, page 5.

(6) Determine if the parts causing the failure are genuine GM parts, non-GM parts labeled "Certified to EPA Standards" or neither. GM parts and "certified" parts are covered under the warranty while non-certified parts will generally not be covered. Refer to item C3, page 3, for policies on emission control systems replacement parts.

(7) If the vehicle qualifies for repair under the Performance Warranty, notify the owner accordingly. If repairs do not qualify, notify the zone office immediately. Refer to item C4, page 4, for policies on owner notification.

(8) Complete qualifying repairs within 30 days or within the time period required by local, state or federal law, whichever is stiorter. Refer to item C5, page 4, for policies on warranty repairs.

(9) Prepare and submit a warranty claim in accordance with the current Claims Preparation Guide.

NOTE: The following items C2 through C6 are based on the Performance Warranty regulations as issued by EPA. They are intended to serve as guidelines only. Of primary importance in evaluating and handling warranty claims is customer satisfaction. The vehicle owner should always receive the benefit of the doubt whenever there is a question as to the eligibility of a claim.

C. 2. Compliance with Maintenance and Use Instructions

Evidence of an owner's compliance with a maintenance instruction may consist of:

A Maintenance Schedule folder which has been validated at the approxi- mate time or mileage intervals specified for service by a dealer or any other qualified automotive service or repair establishment.

A repair order or other form of receipt showing that scheduled mainte- nance has been performed at the approximate time or mileage intervals specified in the folder by the repair establishment.

A statement by the vehicle owner that he or she performed the mainte- nance service at the approximate time or mileage interval specified, including some evidence that:

- The owner purchased and used proper parts; and

- The owner is able to perform the maintenance properly.

C. 3. Policies on Emission Control Systems Replacement Parts

The Performance Warranty covers genuine GM parts as well as parts marked "Certified to EPA Standards". The Performance Warranty regulations define a "certified part" to mean "a part certified in accordance with EPA's aftermarket part certification regulations".

If, upon diagnosis, it is found that the vehicle failed an I/M test as a result of a properly installed non-GM part which ts labeled "Certified to EPA Standards", you must repair or replace the part under the Performance Warranty, at no charge to the vehicle owner. (Procedures will be established upon receipt of the aftermarket part certification regulations which will enable Cadillac to obtain reimbursement from the manufacturer of failed "certified" parts.)

If, on the other hand, the I/M test failure is caused by a non-GM part which is not labeled as being "certified", then you may deny warranty coverage if the part is:

Either defective in materials or workmanship or not equivalent from an emission standpoint to the original equipment part; and

The owner is unable to rebut the evidence.

EPA regulations also set forth the following additional policies on parts:

A part not scheduled to be replaced at a definite interval in accordance with the Cadillac Maintenance Schedule is warranted for the full term of the warranty.

A part (other than a maintenance item) replaced as the result of an instruction in the Maintenance Schedule which reads "check and replace as needed" is covered for the full term of the warranty (e.g. spark plug wires).

If an owner does not follow a "check and replace as needed" maintenance instruction prior to the failure of an I/M test and, as a result, another part failed which relates to the test failure, then this failed part is not covered under the warranty.

Replacement parts installed before the expiration of the warranty are covered for the balance of the warranty period but not less than 90 days or 4,000 miles.

Certified non-GM parts having a maintenance or replacement interval different from that specified in the Cadillac Maintenance Schedule are to be serviced at the ttme and/or mileage interval specified by their manufacturer. It is the responsibility of the owner to arrange for vehicle service at the proper interval.

C. 4. Policies on Owner Notification

Performance Warranty regulations require that the vehicle owner be notified whether or not a repair is covered under the warranty within a "reasonable" time:

"Reasonable" is defined as a period of time not to exceed 30 days from the date the vehicle is initially presented for repair or within the time period during which an owner is required by local, state or federal law to have the vehicle repaired without incurring further penalties or sanctions, whichever is shorter.

The only exceptions would be if the owner requests or agrees to an extension, or if a delay results from events beyond the control of the dealership or Cadillac.

In the event a repair does not qualify under the terms of the Performance Warranty, EPA regulations require that notification of denial be in writing to the owner. In such cases, contact your Zone Service Office immediately, providing full details. They will issue the written denial as applicable. Failure to follow this procedure can lead to severe penalties.

C. 5. Policies on Warranty Repairs

All qualifying adjustments, repairs and replacements made under the Performance Warranty are to be performed within a "reasonable" time and in a good and workmanlike manner to assure that the vehicle:

Complies with applicable EPA emission standards;

Will continue to comply for the remainder of its useful life (if prope, maintenance and operation are continued); and

Will operate in a safe manner.

EPA regulations prohibit adjustments or repairs which are intended only to pass the I/M test without setting the vehicle to manufacturer's specifications. However, this does not mean that dealers are authorized to undertake wholesale replacements of emission control conponents. Rather, every effort should be made to identify and correct only the true cause of I/M test failure.

If for any reason it appears that qualifying repairs cannot be completed within the "reasonable" time period specified in item C4 above, contact your Zone Service Office immediately for assistance.

C. 6. Additional Considerations in Evaluating a Claim

A Performance Warranty claim may be denied on the basis of non-compliance with proper maintenance instructions and use only if:

An owner is unable to comply with a request for maintenance evidence as outlined in item C2; or

The vehicle failed an emission I/M test because:

- The vehicle was abused, or

- Maintenance service was improperly performed, or

- A component affecting the vehicle's emission was removed or rendered inoperative, or

- An uncertified part was used as described in item C3.

In no case, however, may a Performance Warranty claim be denied on the basos of:

Warranty work or pre-delivery service performed by a Cadillac dealer; or

Work performed in an emergency situation to rectify an unsafe condition (including an unsafe drivability condition) provided the vehicle owner has taken steps to put the vehicle back in a conforming condition in a timely manner; or

The use of any uncertified part which is not relevant to the reason the vehicle failed to comply with applicable emission standards; or

Non-compliance with any written instructions for proper maintenance and use which is not relevant to the reason the vehicle failed to comply with applicable emission standards.

D. Performance Warranty Parts List

Listed below is a detailed listing of the parts and labor-only operations covered under the Performance Warranty. This list is the same as the Defect Warranty list in the 1981 Service Policies and Procedures Manual except for the footnotes and deletion of the California Exhaust Emission Option parts (and heavy duty vehicle parts) which are not covered under the Performance Warranty. The numbered headings correspond with the items listed in the Emission Control Systems Warranty presented in the Warranty Information folder. If an owner asks for more information on the specific parts covered by the Performance Warranty, you may give him/her a copy of this list. Also, any parts listed on repair orders should reflect this same terminology.

All items listed below are covered under the Performance Warranty for 5 years or 50,000 miles, whichever occurs first, except for maintenance items and labor-only operations (identified by +) and items identified with an asterisk (*). Maintenance items and labor-only operations are covered only to the point of scheduled replacement as indicated in the Maintenance Schedule folder. For example, a PCV valve which is scheduled for replacement at 30,000 miles, is warranted up to 30,000 miles only.

The asterisked items (*) are the parts which have been in general use prior to model year 1968 and which have not been installed on or in the vehicle for the sole or primary purpose of reducing vehicle emissions. As provided by law, they are covered under the Performance Warranty for 24 months or 24,000 miles, whichever occurs first.

E. Retention of Failed Parts

Failed GM parts and non-GM parts which have been replaced under the Performance Warranty are to be retained the same as other warranty parts in accordance with the Service Policies and Procedures Manual. (Upon release of aftermarket part certification regulations by EPA, further instructions will be provided for handling failed non-GM parts marked "Certified to EPA Standards".)

F. Dealer Certification (Applies to all Dealers)

EPA Performance Warranty regulations require that upon sale of each vehicle, the dealer will furnish to the purchaser a certificate that the vehicle conforms to all applicable EPA emission standards. This certificate is the independent responsibility of the selling dealer (not Cadillac or General Motors Corporation) and must state that it is being made upon the basis of all of the following:

The dealer's knowledge that the vehicle is covered by an EPA certificate of conformity;

The dealer's inspection of the vehicle, including the engine, to assure that all emission related components have been properly installed; and

The dealer's performance of all emission related preparation required by the manufacturer prior to the sale or delivery of the vehicle.

This dealer certificate must further state that if the vehicle fails an EPA-approved emission test prior to the expiration of 3 months or 4,000 miles and the vehicle has been maintained and used in accordance with the written instructions for proper maintenance and use, then the vehicle manufacturer shall remedy the nonconformity under the Emission Performance Warranty. In this case, as mentioned in Paragraph C, the manufacturer is obligated to make no charge repairs without regard to whether a penalty or sanction is imposed upon the owner.

Because this dealer certification responsibility is imposed upon dealers by the Clean Air Act and EPA regulations, Cadillac does not provide forms of certificate. Therefore, they should be prepared in the dealership or obtained from a supplier of dealer forms. An example of the form prepared by NADA is attached for your information only, and should not be considered as having been approved or disapproved by Cadillac.

In the case of courtesy deliveries, the selling dealer should arrange for the servicing dealer to issue the certificate to the purchaser at time of delivery.

*24 month/24,000 mile coverage under Performance Warranty. +Maintenance item. Covered only to the point of scheduled replacement or adjustment.
