TITLE: FMVSS INTERPRETATION

TEXT: We confirm your interpretation of S5.3.2 of Motor Vehicle Safety Standard No. 105-75, expressed in your letter of August 2, 1974, to Dr. Gregory, that the engine "start" position may be used as a check position for indicator lamp function.

The phrase in S5.3.2 "when the ignition (start) switch is in a position between 'on' ('run') and 'start'" is intended to include both "on" and "start" as well as any position between.

Application of the parking brake as an indicator check will no longer be permitted for vehicles manufactured after the effective date of Standard 105-75.
