Federal Emission Control System Warranty

Federal Warranty Coverage is as follows:

Federal Emission Defect Warranty

GM warrants to the owner the following:

Emission related defects in the genuine GM parts listed under the Emission Warranty Parts List covered, including related diagnostic costs, parts, and labor are covered by this warranty.

Federal Emission Performance Warranty

Some states and/or local jurisdictions have established periodic Chassis Inspection and Maintenance (I/M) programs to encourage proper maintenance of the chassis. If an EPA approved I/M program is enforced in your area, you may also be eligible for Emission Performance Warranty coverage when all of the following three conditions are met:

GM warrants that your dealer will replace, repair, or adjust to GM specifications, at no charge to you, any of the parts listed under the "Emission Warranty Parts List" later in this section which may be necessary to conform to the applicable emission standards. Non-GM parts labeled "Certified to EPA Standards" are covered by the Federal Emission Performance Warranty.

California Emission Control System Warranty

This section outlines the emission warranty that GM provides for the chassis in accordance with the California Air Resources Board. Defects in material or workmanship in GM emission parts may also be covered under the Medium Duty Limited Warranty coverage. There may be additional coverage on GM diesel engine chassis. In any case, the warranty with the broadest coverage applies.

This warranty applies if the chassis meets both of the following requirements:

* Important: Maine, Massachusetts, and Vermont have California Emissions Warranty coverage. (New York adopted California emission standards, but not the California Emissions Warranty. The Federal Emissions Control Warranty applies to all non-PZEV vehicles in New York.)

Your Rights and Obligations (For Chassis Subject to California Exhaust Emission Standards)

The Emission Control System Warranty on your vehicle is issued in accordance with the California Air Resources Board and GM. In California, new chassis must be designed, equipped, and built to meet the state's stringent anti-smog standards. GM must warrant the chassis emission control system for the periods of time and mileage listed below provided there has been no abuse, neglect, or improper maintenance of your chassis. The chassis emission control system may include parts such as the fuel injection system, ignition system, catalytic converter, and engine computer. Also included are hoses, belts, connectors, and other emission related assemblies.

Where a warrantable condition exists, GM will repair the chassis at no cost to you including diagnosis, parts, and labor.

California Emission Defect and Emission Performance Warranty Coverage

Any authorized Chevrolet dealer will, as necessary under these warranties, replace, repair, or adjust to GM specifications any genuine GM parts that affect emissions.

The applicable warranty period shall begin on the date the chassis is delivered to the first retail purchaser.

Owner's Warranty Responsibilities

As the vehicle owner, you are responsible for the performance of the scheduled maintenance listed in your owner manual. GM recommends that you retain all maintenance receipts for the chassis, but GM cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

Parts specified in your maintenance schedule that require scheduled replacement are covered up to their first replacement interval or the applicable emission warranty coverage period, whichever comes first. If failure of one of these parts results in failure of another part, both will be covered under the Emission Control System Warranty.

For detailed information concerning specific parts covered by these emission control systems warranties, ask your dealer.

Replacement Parts

The emission control systems of your chassis were designed, built, and tested using genuine GM parts* and the chassis is certified as being in conformity with applicable federal and California emission requirements. Accordingly, it is recommended that any replacement parts used for maintenance or for the repair of emission control systems be new, genuine GM parts.

The warranty obligations are not dependent upon the use of any particular brand of replacement parts. The owner may elect to use non-genuine GM parts for replacement purposes. Use of replacement parts which are not of equivalent quality may impair the effectiveness of emission control systems.

If other than new, genuine GM parts are used for maintenance replacements or for the repair of parts affecting emission control, the owner should assure himself/herself that such parts are warranted by their manufacturer to be equivalent to genuine GM parts in performance and durability.

* "Genuine GM parts," when used in connection with GM chassis means parts manufactured by or for GM, designed for use on GM chassis, and distributed by any division or subsidiary of GM.

Maintenance and Repairs

Maintenance and repairs can be performed by any qualified service outlet; however, warranty repairs must be performed by an authorized dealer except in an emergency situation when a warranted part or a warranty station is not reasonably available to the chassis owner.

In an emergency, where an authorized dealer is not reasonably available, repairs can be performed at any available service establishment or by the owner, using any replacement part. Chevrolet will consider reimbursement for the expense incurred (including diagnosis), not to exceed the manufacturer's suggested retail price for all warranted parts replaced and labor charges based on Chevrolet's recommended time allowance for the warranty repair and the geographically appropriate labor rate. A part not being available within 10 days or a repair not being completed within 30 days constitutes an emergency. Retain receipts and failed parts in order to receive compensation for warranty repairs reimbursable due to an emergency.

If, in an emergency situation, it is necessary to have repairs performed by other than a Chevrolet dealer and you believe the repairs are covered by emission warranties, take the replaced parts and your receipt to a Chevrolet dealer for reimbursement consideration. This applies to both the Federal Emission Defect Warranty and Federal Emission Performance Warranty.

Receipts and records covering the performance of regular maintenance or emergency repairs should be retained in the event questions arise concerning maintenance. These receipts and records should be transferred to each subsequent owner. GM will not deny warranty coverage solely on the absence of maintenance records. However, GM may deny a warranty claim if a failure to perform scheduled maintenance resulted in the failure of a warranty part.

Claims Procedure

As with the other warranties covered in this booklet, take your chassis to any authorized Chevrolet dealer facility to obtain service under the emission warranty. This should be done as soon as possible after failing an EPA-approved I/M test or a California smog check test, or at any time you suspect a defect in a part.

Those repairs qualifying under the warranty will be performed by any Chevrolet dealer at no charge. Repairs which do not qualify will be charged to you. You will be notified as to whether or not the repair qualifies under the warranty within a reasonable time (not to exceed 30 days after receipt of the chassis by the dealer, or within the time period required by local or state law).

The only exceptions would be if you request or agree to an extension, or if a delay results from events beyond the control of your dealer or GM. If you are not so notified, GM will provide any required repairs at no charge.

In the event a warranty matter is not handled to your satisfaction, refer to the "Customer Satisfaction Procedure" in this booklet under Owner Assistance .
