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 and Circuit Breakers on page 5-93. If you have a trailer towing option with added wiring for the trailer lamps, a different turn signal flasher is used. With this flasher installed, 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. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high or high to low, pull the multifunction lever all the way toward you. Then release it. When the high beams are on, this indicator light located on theinstrument panel cluster also will be on. 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. To turn off the chime, move the turn signal lever to the center position. Flash-to-Pass This feature lets you use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are in automatic. To use it, pull the turn signal lever toward you, but not so far that you hear a click. If your headlamps are in automatic or on low beam, your high-beam headlamps will turn on. They'll stay on as long as you hold the lever toward you and the high-beam indicator located on the cluster comes on. Release the lever to return to normal operation. 3-7
