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 5-97. Flash-To-Pass This feature allows you to 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 off. To use it, pull the turn signal lever toward you. If your headlamps are off 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 on the instrument panel cluster will come on. Release the lever to turn the high-beam headlamps off. 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 off position. Headlamp High/Low-Beam Changer To change the headlamps from low to high beam or push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this light on the instrument panel cluster also will be on. Windshield Wipers 8: Mist 9: Off You control the windshield wipers by turning the band with the wiper symbol on it. For a single wiping cycle, turn the band to mist. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. 3-9
