SWITCHES For signaling turns, move the lever up or down in the conventional manner. The ignition key must be in the "ON" position. The turn signal is self-cancelling after a turn, but after a lane change, you may have to cancel it by hand. You can also signal a lane change by moving the turn signal lever partway and holding it there. If the green light in the instrument cluster flashes faster than normal, it indicates that the front or rear turn signal bulb has burned out. If this indicator light does not come on, the fuse or the indicator light itself has probably failed. FOG LIGHT SWITCH 12L005 To turn on the fog lights, turn the switch to the "ON" position. The fog lights come on only when the headlights are on low beam. WINDSHIELD WIPER AND WASHER SWITCH 41
