## NHTSA's summary

Certain vehicles were manufactured with a Safe\-T\-Alert LP/CO detector that incorporated a relay that would shut off the LP supply if the LP/CO went into alarm mode. The LP/CO detectors? wiring from the detector to the relay and solenoid was not installed, however, this has no ill effect on proper operation of the LP/CO detector in detecting unsafe levels of CO or LP gas.
