6-4 Lighting An arrow on the instrument cluster flashes in the direction of the turn or lane change. 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 moved momentarily to the lane change position, the arrow will flash three times. The lever returns to its starting position whenever it is released. If after signaling a turn or a lane change the arrow flashes rapidly or does not come on, a signal bulb may be burned out. Replace any burned out bulbs. If a bulb is not burned out, check the fuse. See Fuses and Circuit Breakers on page 10-20.
