§ 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-highway recreational vehicle 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 off-highway recreational 

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 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.

(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-highway recreational 

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 
13

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.

(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 or adjustment instructions that appear on 

labels shall be sufficiently clear and complete so as to preclude the need for a 

mechanic 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, off-road sport vehicle, off-road utility vehicle, sand 

car, or engine, as applicable) conforms to California regulations applicable to 

(specify applicable model year) model-year new (specify off-road motorcycles, 

all-terrain vehicles, off-road sport vehicles, off-road utility vehicles, sand cars, or 

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

to (specify applicable HC standard in grams per kilometer) HC engine family 
14

exhaust emission standard in California” or the phrase “is certified to (specify 

applicable HC+NOx standard in grams per kilowatt-hour) HC+NOx 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 recreational vehicle or engine 

conforms to any applicable federal emission standards for new off-road 

motorcycles, all-terrain vehicles, off-road utility 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.

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

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

recreational vehicle environmental conditions at the location where a label has 

been attached. Typical off-highway recreational 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 
15

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
