Turn Signal and Lane Change Indicator A green arrow on the instrument panel will flash in the direction of the turn or lane change. To signal a lane change, just raise or lower the lever until the green arrow starts to flash. Hold it there until you complete your lane change. The lever will return by itself when you release it. 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. As you signal a turn or a lane change, if the arrows don't flash but just stay on, a signal bulb may be burned out and other drivers won't see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the green arrows don't go or1 at all when you signal a turn, check the fuse (see "Fuses" in the Index) and .for burned-out bulbs.
