yellowblue Multifunction Lever Turn Signal and Lane Change Indicator 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 will flash in the direction of the turn or lane change. The lever on the left side of the steering column includes your: D D D D D Turn Signal and Lane Change Indicator Headlamp High/Low Beam Changer Windshield Wipers Windshield Washer Cruise Control (If Equipped) To signal a lane change, just 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 move the lever all the way up or down and the arrow flashes at twice the normal rate, a signal bulb may be burned out and other drivers may not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the 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). 2-34
