ATTACHMT: Attached to letter/fax dated 12/14/93 from J. Hulshof to Patrick Boyd (OCC 9448)

TEXT:

This responds to your letter to Mr. Patrick Boyd requesting a written interpretation concerning whether your sunroof would meet the requirements of Federal Motor Vehicle Safety Standard No. 118, "Power-Operated Window, Partition, and Roof Panel systems." I apologize for the delay in responding.

By way of background, the National Traffic and Motor Vehicle Safety Act establishes a self-certification system under which manufacturers are responsible for ensuring that their products comply with all applicable FMVSSs. We do not approve, endorse, or gives assurances of compliance of any product. In response to manufacturers' requests for interpretations of the FMVSS's, we try, to the extent possible, to provide information that will help them make their determinations of compliance. However, these responses are based on information provided by the manufacturer, and are subject to the findings of actual compliance testing by the agency. Should the agency, in the future, examine your product and detect an apparent noncompliance or defect, those results will control.

You explain in your letter that your power-operated sunroof (which is a power operated "roof panel system" under Standard 118) can be closed only in four circumstances. In three of these, the ignition key must be activated. In the fourth, the sunroof can be closed when there is "Continuous operation of Central close mechanism, not capable (sic) closing the roof panel from a distance of more than 6 meters from the vehicle."

Standard 118 requires sunroofs other than those that have an automatic reversing feature to close only in certain circumstances. One of those (S4(a)) is when the key controlling the vehicle's engine is in the activated (i.e. "on", "start" or "accessory") position. The three circumstances you described where the ignition key must be activated to operate the sunroof appear to satisfy S4(a).

With regard to the fourth circumstance, Standard 118 also permits sunroofs to close "Upon continuous activation of a remote actuation device, provided that the...device shall be incapable of closing the (sunroof) from a distance of more than 6 meters from the vehicle" (S4(d)). The circumstance you described appears to satisfy S4(d). Your sunroof will close only upon continuous operation of a "Central close mechanism," and the mechanism is incapable of closing the sunroof from a distance of more than 6 meters from the vehicle.

I hope this information has been helpful. If you have any further questions, please contact Mr. David Elias of my office at the above address or by phone at (202) 366-2992.
