Features & Controls 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 turnor a lane change. To signal a turn, move the lever all the way up or down. When the turn is finished, the lever willreturn automatically. 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 untilthe 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 drivers won't see your turn signal. If you have the Driver Information Center, it will tell you if you have a burned out bulb. See the Index under Driver Information Center. If a bulb is burnedout, replace it to help avoid an accident. If the green arrows don't go on at all when you signala turn, check the fuse (see the Index under Fuses & Circuit Breakers) and for burned-out bulbs. If you have a trailer towing option with added wiring for the trailer lights, a different turn signal flasher is used. With this flasher installed, the signal indicator will flash even if turn signal a bulb is burned out. Check the front and rear turn signal lights regularly to make sure they are working. ... 74
