TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of September 25, 1979, requesting an interpretation of the term "restraint system type" as contained in Table I of S4.5.2 of Federal Motor Vehicle Safety Standard No. 115. In addition, this is in confirmation of Volkswagen's statement of the conclusions reached in the meeting with Messrs. Carson, Parker and Schwartz of the National Highway Traffic Safety Administration.

The agency has carefully considered your request that "restraint system type" not be interpreted to require a distinction between active and passive belt systems. The agency must deny your request. As the introduction of mandatory passive restraints approaches, information concerning restraint system type is of exceptional importance to the agency. It is important not only to evaluate the overall effectiveness of passive restraints, but also to determine the effectiveness of the various types of passive restraint system types. Consequently, it is necessary that passive belt systems be differentiated from other restraint system types by decoding the vehicle identification number (VIN).

The agency has also considered the alternative Volkswagen suggested which is to submit this information separately to the agency on a magnetic tape. Motor vehicle safety research is carried out by many organizations aside from the NHTSA, however, and Standard No. 115 is intended to make information available to these other researchers as well. Consequently, the agency can not accept the alternative you suggest.

As regards to other questions raised in the meeting with NHTSA staff, this is to confirm that paragraphs 2 through 4 of our November 20, 1978, letter remain the position of the agency despite the changes in Standard No. 115 since that time. A copy of that letter is enclosed. Likewise, the agency can confirm that the World Manufacturer Identifiers assigned to Volkswagen by the Society of Automotive engineers fulfill the requirements of S6.1 of Standard No. 115.

As requested, the agency has reviewed the VIN format Volkswagen intends to utilize (attachments 2-4 of this letter) and has determined that it meets the requirements of the standard. As explained at the meeting, specific details concerning an engine need not be encoded so long as the information is available from the manufacturer and different engine types can be differentiated by means of the VIN (S4.5.2).

Volkswagen also pointed out to the agency at the meeting that the first eight characters of the VIN for a particular model might remain the same for several model years, although the characteristics of the vehicle which they codify might change from model year to model year. For example, a 1981 Dasher might have a different engine than a 1982 Dasher, yet that part of the VIN which contains this information would remain the same. This is authorized by Standard No. 115, so long as the correct information for each model year is submitted to the agency.

Volkswagen also asked at the meeting what the correct procedure would be for submitting information to the agency concerning vehicles whose line is not subdivided into several series. In this instance, indicate that the line and series are the same. However, even if the series is not divided into more than one body type, this body type must be reported to the agency (S4.5.2). The engine displacement may be indicated in cubic centimeters, and the horsepower in H.P. SAE net (3). If only one engine make is used, this information must be submitted to the agency, but need not be directly reflected in the VIN (S6.3).

Volkswagen has also asked when information concerning vehicles imported into the United States must be submitted to the agency. Manufacturers of imported vehicles are required to report VIN codes 60 days before the vehicles are imported into the United States to comply with S6.2.

The agency is considering the petitions of a number of manufacturers to establish engine horsepower groupings for reporting purposes and to establish a flexible effective date for vehicles whose model year begins between September 1, 1980 and December 31, 1980. We expect to respond shortly to the petitions.

Sincerely,

ATTACH.

SEPTEMBER 25, 1979

Frank Berndt -- Chief Counsel, National Highway Traffic Safety Administration

Dear Mr. Berndt:

On September 8, 1978 representatives of Volkswagen of America, Inc. and Volkswagenwerk AG met with Messrs. Carson, Erickson, Parker and Schwartz of the NHTSA to discuss Federal Motor Vehicle Safety Standard 115, Vehicle Identification Number (VIN). In that meeting an interpretation of "restraint system type" was brought up. It was suggested by Mr. Schwartz that Volkswagen submit a formal request for interpretation. Accordingly, this letter is a formal request for interpretation of the term "restraint system type" contained in paragraph S4.5.2, Table I of Federal Motor Vehicle Safety Standard 115, (VIN).

VW is currently in the process of finalizing the VW system of coding the VDS section of the VIN. The concern is that additional expense would be involved at Volkswagen of America if the term "restraint system type" were interpreted as requiring a distinction between active and passive belt systems.

As you may be aware, the VW passive belt system is currently offered as standard equipment on the Deluxe version of the Rabbit. Accordingly, the designation of Deluxe Rabbit in the VIN will automatically identify the majority of VW vehicles equipped with passive belts. In addition, the passive belt system is offered as an option on the Custom model of the Rabbit. In this case the option information is difficult to access by the computer. This effort will require an additional 10 hours/month computer time to determine if the Rabbit Custom is equipped with the passive belt system.

A more efficient way is available to identify VW vehicles equipped with the passive belt system. VW is proposing that in lieu of identifying the passive belt system in the VIN, a computer tape be submitted to the NHTSA on a semi-annual basis with all pertinent information pertaining to all VW vehicles sold within the United States that are equipped with the passive system. Supplying this type of information would be more efficient and more convenient for the NHTSA than coding the passive belt option in the VIN.

We request your interpretation and opinion on this proposal as soon as possible since finalizing the VIN coding is nearing completion. For any additional details on this request, please contact Mr. Charles A. Preuss at (313) 588-5505.

Best regards,
