The emission warranty on your vehicle is issued in accordance with the U.S. Federal Clean Air Act. Defects in material or workmanship in GM emission parts may also be covered under the New Vehicle Limited Warranty Bumper-to-Bumper coverage. There may be additional coverage on GM diesel engine vehicles. In any case, the warranty with the broadest coverage applies.
What Is Covered
The parts covered under the emission warranty are listed under "Emission Warranty Parts List" later in this section.
How to Determine the Applicable Emissions Control System Warranty (Light Duty Trucks Only)
State and Federal agencies may require different emission control system warranty for light duty trucks depending on:
| • | Whether the truck is certified with a light duty or heavy duty emission control system. |
| • | Whether the truck is certified for California emissions in addition to Federal emissions. |
To determine emissions eligibility: locate the emission control label in the engine compartment on the air cleaner assembly or on the engine. The language on the bottom left side of the label will describe if equipped with a light, medium, or heavy duty emission control system.
All light duty trucks are eligible for Federal Emissions Control System Warranty Coverage. If the emissions control label contains language stating the vehicle is certified to California emissions standards, the vehicle is also eligible for California Emissions Control System Warranty Coverage.
Federal Emission Control System Warranty
Federal Warranty Coverage
| • | Car and Light Duty Truck equipped with Car and Light Duty Gasoline Engines |
| - | 2 years or 24,000 miles and 8 years or 80,000 miles for the catalytic converter or vehicle, powertrain, control module, whichever comes first. |
| • | Light Duty Truck equipped with Heavy Duty Gasoline Engine |
| - | 5 years or 50,000 miles, whichever comes first. |
| • | Light Duty Truck equipped with Heavy Duty Diesel Engine |
| - | 5 years or 50,000 miles, whichever comes first. |
Federal Emission Defect Warranty
GM warrants to the owner the following:
| • | The vehicle was designed, equipped, and built so as to conform at the time of sale with the applicable regulations of the Federal Environmental Protection Agency (EPA). |
| • | The vehicle is free from defects in material and workmanship which cause the vehicle to fail to conform with those regulations during the emission warranty period. |
Emission related defects in the genuine GM parts listed under the Emission Warranty Parts List, 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 vehicle Inspection and Maintenance (I/M) programs to encourage proper maintenance of your vehicle. 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:
| • | The vehicle has been maintained and operated in accordance with the instructions for proper maintenance and use set forth in the owner manual supplied with your vehicle. |
| • | The vehicle fails an EPA-approved I/M test during the emission warranty period. |
| • | The failure 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. |
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 your vehicle in accordance with the California Air Resources Board. Defects in material or workmanship in GM emission parts may also be covered under the New Vehicle Limited Warranty Bumper-to-Bumper coverage. There may be additional coverage on GM diesel engine vehicles. In any case, the warranty with the broadest coverage applies.
This warranty applies if your vehicle meets both of the following requirements:
| • | Your vehicle is registered in California or other states adopting California emission and warranty regulations*. |
| • | Your vehicle is certified for sale in California as indicated on the vehicle's emission control information label. |
Important: Massachusetts, Maine, 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 vehicles in New York.)
Your Rights and Obligations (For Vehicles 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 motor vehicles must be designed, equipped, and built to meet the state's stringent anti-smog standards. GM must warrant your vehicle's emission control system for the periods of time and mileage listed provided there has been no abuse, neglect, or improper maintenance of your vehicle. Your vehicle's 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 your vehicle at no cost to you including diagnosis, parts, and labor.
California Emission Defect and Emission Performance Warranty Coverage
For cars and trucks with light duty or medium duty emissions:
| • | For 3 years or 50,000 miles, whichever comes first: |
| - | If your vehicle fails a smog check inspection, GM will make all necessary repairs and adjustments to ensure that your vehicle passes the inspection. This is your Emission Control System Performance Warranty. |
| - | If any emission related part on your vehicle is defective, GM will repair or replace it. This is your Short-term Emission Defects Warranty. |
| • | For 7 years or 70,000 miles whichever comes first: |
| - | If an emission related part listed in this booklet specially noted with coverage for 7 years or 70,000 miles is defective, GM will repair or replace it. This is your Long-term Emission Control System Defects Warranty. |
| • | For 8 years or 80,000 miles, whichever comes first: |
| - | If the catalytic converter or vehicle, powertrain, control module is found to be defective, GM will repair or replace it under the Federal Emission Control System Warranty. |
| • | For heavy duty gasoline engine vehicles, the emission warranty period is 5 years or 50,000 miles, whichever comes first. |
| • | For heavy duty diesel engine vehicles, the emission warranty period is 5 years, 100,000 miles, or 3,000 hours of operation, whichever comes first. |
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 vehicle is delivered to the first retail purchaser or, if the vehicle is first placed in service as a demonstrator or company vehicle prior to sale at retail, on the date the vehicle is placed in such service.
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 your vehicle, but GM cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
You are responsible for presenting your vehicle to a GM dealer selling your vehicle line as soon as a problem exists. The warranted repairs should be completed in a reasonable amount of time, not to exceed 30 days.
As the vehicle owner, you should also be aware that GM may deny warranty coverage if your vehicle or a part has failed due to abuse, neglect, improper or insufficient maintenance, or modifications not approved by GM.
If you have any questions regarding your rights and responsibilities under these warranties, you should contact the Customer Assistance Center at 1-800-222-1020 or, in California, write to:

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 vehicle were designed, built, and tested using genuine GM parts* and the vehicle 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 vehicles means parts manufactured by or for GM, designed for use on GM vehicles, 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 vehicle owner.
In an emergency, where an authorized dealer is not reasonably available, repairs may 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 vehicle 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 vehicle 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" under Owner Assistance .
