If your vehicle is equipped with the Head-Up Display (HUD), an arrow will also appear in the display area to indicate the direction of the turn or lane change. See Head-Up Display (HUD) on page 3-19 for more information. You may also have an arrow in the outside mirror that flashes when the turn signal is used. See Outside Power Mirrors on page 2-37 for more information. 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. As you signal a turn or a lane change, if the arrows flash at twice the normal rate, this may indicate that 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 the fuse and check for burned-out bulbs. See Fuses and Circuit Breakers on page 5-92. If you have a trailer towing option with added wiring for the trailer lamps, the signal indicator will flash even if a turn signal bulb is burned out. Check the front and rear turn signal lamps regularly to make sure they are working. You do not need to add a different flasher. Turn Signal On Chime If your turn signal is left on for more than three-quarters of a mile (1.2 km), a chime will sound at each flash of the turn signal. To turn off the chime, move the turn signal lever to the off position. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam or high beam to low beam, pull the turn signal lever toward you and release it. While the high beams are on, this light located on the instrument panel cluster will also be on. If your vehicle is equipped with the Head-Up Display (HUD), this symbol will also appear in the display area to indicate the high beams are on. See Head-Up Display (HUD) on page 3-19 for more information. 3-8
