To signal a lane change, raise or lower the lever until the arrow starts to flash. Hold it there until you complete your lane change. The lever will return by itself when you release it. If you momentarily press and release the lever, the turn signal will flash three times. If the arrow flashes faster than normal as you signal a turn or a lane change, a signal bulb may be burned out and other drivers will not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check for burned-out bulbs and then check the fuse. See Fuses and Circuit Breakers on page 490. Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically. An arrow on the instrument panel cluster will flash in the direction of the turn or lane change. Turn Signal On Chime If you leave either one of your turn signals on and drive more than 3/4 mile (1.2 km), a chime will sound to alert you. 175
