yellowblue An arrow on the instrument panel will flash in the direction of the turn or lane change. 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. Note: You do not need to add a different flasher. Turn Signal On Chime 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. 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 won't 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 the fuse (see "Fuses and Circuit Breakers" in the Index) and for burned-out bulbs. 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. 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 or high to low, pull the turn signal lever toward you, then release it. When the high beams are on, a light on the instrument panel will also be on. If your vehicle is equipped with HUD, this light will also appear in the display area. 2-37
