Turn and Lane-Change Signals 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. To signal a lane change, raise or lower the lever for less than one second until the arrow starts to flash. This will cause the turn signals to automatically flash three times. It will flash six times if tow-haul mode is active. Holding the turn signal lever for more than one second will cause the turn signals to flash until you release the lever. The lever will return by itself when it is released. 206 As you signal a turn or a lane change, if the arrows flash more quickly than normal, a signal bulb may be burned out and other drivers will not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check for burned-out bulbs and a blown fuse. See Fuses and Circuit Breakers on page 564. Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each flash of the turn signal and the message TURN SIGNAL ON will also appear in the Driver Information Control (DIC). To turn the chime and message off, move the turn signal lever to the off position.
