Turn Signal and Lane Change Indicator The turn signal has two upward (for right signal) and two downward (for left signal) positions. These positions allow you t o 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... A green arrow on the r L instrument panel will flash in the direction of the turn or lane change. ! i 1, 1 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. As you signal a turn or a lane change, if the arrows flash at twice the normal rate, a signal bulb may be burned o u t and other drivers may not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the green arrows don't go on at all when you signal a turn, check for burned-out bulbs and a blown fuse (see "Fuses" in the Index). 2-40
