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:
• The chassis is registered in California or
other states adopting California emission
and warranty regulations*.
• The chassis conforms to California regulations
as indicated on the chassis emission control
label.
Important: *Massachusetts, Maine, and
Vermont have California Emissions Control
System Warranty coverage. (New York adopted
California emission standards, but not the California
emissions warranty. The Federal Emissions
Control System warranty applies to all 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.
