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 arrow flashes faster 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 check the fuse. See Bulb Replacement on page 5-49 and Fuses and Circuit Breakers on page 5-96. If you have a trailer towing option with added wiring for the trailer lamps, the signal indicator will flash at a normal rate 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 beam, push the turn signal/multifunction lever away from you. When the high beams are on, this light will appear on the instrument panel cluster. To change the headlamps from high beam to low beam, pull the turn signal/multifunction lever toward you. Flash-to-Pass When the headlamps are off, pull the lever toward you to momentarily turn on the high beams. This will signal that you are going to pass. When you release the lever, they will turn off. Turn Signal On Chime If either turn signal is left on for more than 3/4 mile (1.2 km), a chime will sound to let the driver know to turn it off. If you need to leave the signal on for more than 3/4 mile (1.2 km), turn off the signal and then turn it back on. 3-8
