§ 2413. Emission Control Labels – New Off-Highway Recreational Vehicles. 

(a) Purpose. The Air Resources Board recognizes that certain 

emissions-critical or emissions-related parts must be properly identified and 

maintained in order for off-highway recreational vehicles, and engines used in 

such vehicles, to comply with the applicable emission standards. The purpose of 

this section is to require off-road motorcycle and ATV engine manufacturers to 

attach a label (or labels) on each production vehicle (or engine) in order to 

provide vehicle owners and service mechanics with information necessary for the 

proper maintenance of these vehicles and engines in customer use.

(b) Applicability

(1) All off-road motorcycles, all-terrain vehicles, and engines used in such 

vehicles, except those certified according to section 2412(f), produced on or after 

January 1, 1997, for sale, lease, use or introduction into commerce in California, 

shall comply with these labeling requirements. of Title 13, California Code of 

Regulations, Chapter 1, Article 2, Section 1965, and the incorporated “California 

Motor Vehicle Emission Control and Smog Index Label Specifications,” adopted 

March 1, 1978, as last amended June 24, 1996 (as corrected 

September 20, 1996), and which are hereby incorporated by reference herein. 

Any reference to motorcycles in the incorporated documents this section 2413

applies to off-road motorcycles, all-terrain vehicles, and engines used in such 

vehicles. 

(2) Any off-road motorcycle, all-terrain vehicle, and engines used in such 

vehicles, that are exempt from exhaust emission standards pursuant to title 13 of 

the California Code of Regulations shall also be exempt from the requirements of 

this section.

(3) The responsibility for compliance with this section rests with the 

manufacturer who has been granted certification in order to offer these vehicles 

and engines for sale in California.
7

(c) Label Content and Location

(1) A tune-up label made of a permanent material shall be welded, riveted 

or otherwise permanently attached to an area on the off-road motorcycle, 

all-terrain vehicle, or engine in such a manner that the label will be readily visible 

to the average person after the engine installation.

(2) 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). 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 that is likely to be replaced during the vehicle’s useful life. 

Labels shall not be affixed to any part that is likely to be replaced in the useful life 

of the vehicle.

(3) The tune-up label shall be in the English language, and use block 

letters and numerals, which shall be of a color that contrasts with the background 

color of the label.

(4) The tune-up label shall contain the following information:

(A) A label heading that shall read: “Vehicle Emission Control 

Information.”

(B) The complete corporate name and trademark of the 

manufacturer.

(C) Engine family name and engine displacement (in cubic 

centimeters).

(D) Identification of the Exhaust Emission Control System 

Abbreviations may be used and shall conform to the nomenclature and 

abbreviations found in the Society of Automotive Engineers’ document 

J1930, which is incorporated by reference in section 1977, title 13, CCR, 

entitled “Electrical/Electronic Systems Diagnostic Terms, Definitions, 

Abbreviations, and Acronyms.”

(E) The tune-up specifications and adjustments recommended by 

the manufacturer, including, if applicable: valve lash, ignition timing, idle 

air fuel mixture setting procedure and value (e.g., CO, idle speed drop), 

and high idle speed. These specifications shall indicate the proper 

transmission position during tune-up and what accessories, if any, should 

be in operation, and what systems, if any (e.g., vacuum advance, air 

pump), should be disconnected during the tune-up. Any tune-up 

specifications of adjustment instructions that appear on labels shall be 

sufficiently clear and complete so as to preclude the need for a mechanic 
8

or vehicle owner to consult other references in order to correctly perform 

the adjustments. The manufacturer shall include the single statement: “No 

other adjustments needed,” in lieu of any tune-up adjustment instruction, 

when the manufacturer does not recommend a tune-up specification or an 

adjustment.

(F) Any specific fuel or engine lubricant requirements (e.g., 

research octane number, engine lubricant type, etc.).

(G) An unconditional statement of compliance with the appropriate 

model-year California regulations. For example, “This (specify off-road 

motorcycle, all-terrain vehicle, or engine, as applicable) conforms to 

California regulations applicable to (specify applicable model year) 

model-year new (specify off-road motorcycles, all-terrain vehicles, or 

engines, as applicable). The statement shall also include the phrase, “is 

certified to (specify applicable HC standard) HC engine family exhaust 

emission standard in California.”

(H) Statements such as those in (G) shall not appear on labels 

placed on off-highway recreational vehicles or engines that do not comply 

with all applicable California regulations.

(5) A manufacturer may elect to use a supplemental label when the 

original label lacks sufficient space to include all the required information. A 

supplemental label shall conform to all of the specifications as the original label. 

The original label shall be indicated as “1 of 2” and the supplemental label shall 

be indicated as “2 of 2” whenever a supplemental label is utilized.

(6) The provisions of this section shall not prevent a manufacturer from 

also reciting on the label that such off-highway vehicle or engine conforms to any 

applicable federal emission standards for new off-road motorcycles, all-terrain 

vehicles, or engines used in such vehicles, or any other information that such 

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

satisfactory maintenance of such off-highway vehicles or engines.

(7) As used in this Section 2413(c), readily visible to the average person 

means that the label shall be readable from a distance of 18 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 (2 millimeters in 

height) provided that no vehicle or engine parts (including all manufacturer 

available optional equipment), except for flexible parts, obstruct the label.
9

(8) The labels and any adhesives used shall be designed to withstand, for 

the off-highway vehicle’s total expected life, typical off-highway vehicle 

environmental conditions at the location where a label has been attached. 

Typical off-highway vehicle environmental conditions include, but are not limited 

to, exposure to engine fuels, lubricants and coolants (e.g., gasoline, motor oil, 

brake fluids, ethylene glycol), engine operating temperatures, steam cleaning, 

and paints or paint solvents. The manufacturer must submit, with its certification 

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

(9) The manufacturer must obtain approval from the Executive Officer for 

all emission control label formats and locations prior to certification. Approval of 

the specific tune-up specifications and adjustments is not required; however, the 

format for all such specifications and adjustments, 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, 

the Executive Officer may require that the label or its location be modified 

accordingly.

(10) Samples of all actual production emission control labels used within 

an engine family shall be submitted to the Executive Officer of the state Air 

Resources Board within thirty days after the start of production.

(11) The Executive Officer may approve alternate label locations or may, 

upon request and when the Executive Officer determines warranted, waive or 

modify one or more of the label content requirements, provided that the intent of 

this section is satisfied.

(12) If the Executive Officer finds any off-road motorcycle, all-terrain 

vehicle, or engine manufacturer using emission control labels that are different 

from those approved or that do not substantially comply with the readability or 

durability requirements set forth in this section, the Executive Officer may invoke 

section 2109, title 13, California Code of Regulations.
