To signal a turn, move the lever all the way up or down. When the turn is finished, the leverwill return automatically. I instrument panel will flash in the direction of the turn or lane change. A green arrow on the To signal a lane change, justraise 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 don't flash but just stay on, a signal bulb may be burned out and other driverswon'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 on at all when you signal a turn, check for burned-out bulbs and a blown fuse (see "Fuses" in the Index). 2-39
