CONTROLS - Dash Switches This switch operates the emergency flashers. With the switch in the ON position, the emergency flasher makes all four turn signals (front and rear) flash simultaneously. The flasher works independently of the ignition switch. You should always use the flasher if the vehicle is disabled or parked under emergency conditions. the dash lights, side, and tail lights are also on. Headlights will turn on if the windshield wipers are turned on. Manually turning the headlights on and then off will override this function until the next time the vehicle is turned on. NOTE An interrupt switch for the trailer mark- er lights is mounted on the end of the turn signal lever.
