AIR RESOURCES BOARD

California Motor Vehicle Emission Control and

Smog Index Label Specifications

1. Purpose. The Air Resources Board recognizes that certain emissions-critical or

emissions-related parts must be properly identified and maintained in order for vehicles and

engines to meet the applicable emission standards. The purpose of these specifications is: (1)

to require motor vehicle or motor vehicle engine manufacturers to affix a label (or labels) on each

production vehicle in order to provide the vehicle owner and service mechanic with information

necessary for the proper maintenance of these parts in customer use and (2) to require that

smog index labels be affixed to motor vehicle windows. These Emission Control and Smog

Index Label Specifications are incorporated by reference in Section 1965, Title 13, California

Code of Regulations.

2. Applicability.

(a) The specifications for tune-up labels, vehicle emission configuration barcode labels, and vehicle identification number bar-code labels shall apply to all new 1979

through 2003 and subsequent model-year passenger cars, light-duty trucks, medium-duty

vehicles, heavy-duty engines, and to all new 1982 through 2003 and subsequent model

year motorcycles and motorcycle engines certified to the applicable emission standards

pursuant to California Health and Safety Code Sections 43100 and 43107. The

“unleaded gasoline only” labeling requirements in section 3.(d) do not apply to 1997

through 2003 and subsequent model year vehicles.

(b) The specifications for smog index labels shall apply to all new passenger

cars and light-duty trucks 0-8500 pounds gross vehicle weight. This labeling requirement

shall be effective starting with the 1998 model year.

(c) Any vehicles or classes of vehicles exempt from exhaust emission

standards pursuant to Title 13 of the California Code of Regulations shall also be exempt

from the requirements of these specifications except Zero-Emission Vehicles (ZEVs)

certified by the Air Resources Board for use in California.

(d) The responsibility for compliance with these specifications shall rest with

the motorcycle, motorcycle engine, light-duty vehicle, medium-duty vehicle, or heavy-duty

engine manufacturer who certified such vehicles or engines.

3. Emission Control Labels. A plastic or metal tune-up label, and in accordance with

Section b, a machine-readable vehicle emission configuration (VEC) bar-code label made of

paper, plastic, metal, or other permanent material, shall be welded, riveted or otherwise

permanently attached to an area within the engine compartment (if any) or to the engine in such a

way that it will be readily visible to the average person after installation of the engine in a vehicle.

In accordance with Section b, a machine-readable vehicle identification number (VIN) bar-code

label made of paper, plastic, metal, or other permanent material shall be affixed in a readily

visible location to either the door-latch post next to the driver's seating position, the door edge

that meets this door-latch post, or above the instrument panel in a location clearly visible through

the lower left corner of the windshield.

In selecting an acceptable location, the manufacturer shall consider the possibility of

accidental damage (e.g., possibility of tools or sharp instruments coming in contact with the

label) and accessibility for a bar-code scanner, as applicable. Each label shall be affixed in

such a manner that it cannot be removed without destroying or defacing the label, and shall not

be affixed to any part which is likely to be replaced during the vehicle's useful life. For

motorcycles and motorcycle engines, passenger cars, light-duty trucks, and medium-duty

vehicles, the label(s) shall not be affixed to any equipment, which is easily detached from the

vehicle.

(a) The tune-up label shall contain the following information lettered in the

English language in block letters and numerals which shall be of a color that contrasts with

the background of the label:

i. The label heading shall read: “Vehicle Emission Control Information” for

passenger cars, light-duty trucks, medium-duty vehicles, motorcycles and

motorcycle engines, and “Important Engine Information” for heavy-duty engines.

ii. Full corporate name and trademark of the manufacturer.

iii. For 1993 and subsequent model-year vehicles and engines designed to be

capable of operating on fuels other than gasoline, the statement "This 

 (specify vehicle or engine, as applicable) is certified to operate on 

(specify operating fuel[s])."

iv. Engine family or test group identification, model designation, engine displacement

(c) The tune-up label shall include a vacuum hose routing diagram showing all

emissions-related and emissions-critical parts that are actuated by vacuum and the

correct routing of vacuum hoses if one or more vacuum hoses are employed. This

diagram shall contain no more than two different vacuum hose routing patterns; if there

are two routings on a single diagram each routing must be easily understandable. The

hose diagram may be separated from the tune- up label provided that the vacuum hose

diagram is placed in a visible and accessible position as provided in this section. If a

separate label is used, it shall be of a permanent type; however the destruction limits in

this section do not apply. ZEVs are exempt from these requirements.

(d) The manufacturer of any vehicle equipped with an emission control device

which the Executive Officer has determined will be significantly impaired by the use of

leaded gasoline shall:

i. At the time of vehicle manufacture, affix two or more permanent legible labels

specifying the appropriate operating fuel(s) (for example "Methanol Fuel or

Unleaded Gasoline Only" for fuel-flexible vehicles) as follows:

(1) One label shall be located on the instrument panel so as to be

readily visible to the operator of the vehicle: Provided, however, that the

required statement may be incorporated into the design of the instrument

panel rather than provided on a separate label; and

(2) One label shall be located immediately adjacent to each fuel tank

filler inlet, outside of any filler inlet compartment, and shall be located so as to be

readily visible to any person introducing fuel to such filler inlet: Provided, however,

that the Executive Officer may, upon application from a motor vehicle

manufacturer, approve other label locations that achieve the purpose of this

paragraph.

(3) Such labels shall be in the English language in block letters which

shall be of a color that contrasts with their background.

ii. For purposes of this section a motor vehicle shall be deemed to be equipped with

an emission control device which will be significantly impaired by the use of

(d) Fleet Average Smog Indices: [Editorial Note: The 2004 and subsequent model

year fleet average smog indices may be found in the “California Smog Index Label

Specifications.”]

The following fleet average smog indices shall apply to 2001 through 2003 model-year

passenger cars and light-duty trucks 0-5750 lbs. LVW, and 2004 and subsequent model-year

passenger cars and light-duty trucks 0-8500 lbs. GVW:

4. The provisions of these specifications shall not prevent a manufacturer from also

reciting on the label that such vehicle or engine conforms to any applicable federal emission

standards for new motor vehicles or new motor vehicle engines or any other information that

such manufacturer deems necessary for, or useful to, the proper operation and satisfactory

maintenance of the vehicle or engine.

5. As used in these specifications, readily visible to the average person shall mean

that the label shall be readable from a distance of eighteen inches (46 centimeters) without any

obstructions from vehicle or engine parts (including all manufacturer available optional

equipment) except for flexible parts (e.g., vacuum hoses, ignition wires) that can be moved out of

the way without disconnection. Alternatively, information required by these specifications to be

printed on the label shall be no smaller than 8 point type size provided that no vehicle or engine

parts, (including all manufacturer available optional equipment), except for flexible parts, obstruct

the label. For the VEC and VIN labels, sufficient clearance shall be provided to use a

non-contact bar-code scanner.

6. For the tune-up label and vacuum hose routing diagram label, the labels and any

adhesives used shall be designed to withstand, for the vehicle's total expected life, typical

vehicle environmental conditions in the area where the label is attached. Typical vehicle

environmental conditions shall include, but are not limited to, exposure to engine lubricants and

coolants (e.g., gasoline, motor oil, brake fluids, water, ethylene glycol), underhood temperatures,

steam cleaning, and paints or paint solvents. The manufacturer shall submit, with its certification

application, a statement attesting that its labels comply with this requirement.

VEC and VIN machine-readable labels shall meet the applicable functional test

specifications contained in SAE standards J1892 (OCT 1993) and J1877 (JUL 1994).

7. The manufacturer shall obtain approval from the Executive Officer for all emission

control label formats and locations prior to use. Approval of the specific tune-up settings is not

required; however, the format for all such settings and tolerances, if any, is subject to review. If

the Executive Officer finds that the information on the label is vague or subject to

misinterpretation, or that the location does not comply with these specifications, he or she may

require that the label or its location be modified accordingly.

8. Samples of all actual production emission control labels used within an engine

family shall be submitted to the Executive Officer within thirty days after the start of production.

9. The Executive Officer may approve alternate label locations or may, upon request,

waive or modify the label content requirements provided that the intent of these specifications is

met.

10. If the Executive Officer finds any motor vehicle or motor vehicle engine

manufacturer using emission control labels which are different from those approved or which do

not substantially comply with the readability or durability requirements set forth in these

specifications, the Executive Officer may invoke Section 2109, Title 13, California Code of

Regulations.

11. The sale and registration in this state of any certified new 1998 through 2003 and

subsequent model passenger car or light-duty truck to which a smog index label has not been

affixed in accordance with these procedures is prohibited.
