6-4 Lighting Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is completed. If the lever is briefly pressed and released, the turn signal flashes three times. The lever returns to its starting position whenever it is released. If after signaling a turn or lane change the arrow flashes rapidly or does not come on, a signal bulb may be burned out. Have any burned out bulbs replaced. If a bulb is not burned out, check the fuse. See Fuses and Circuit Breakers on page 10-28. The turn signals do not work while the hazard warning flashers are on.
