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 check the fuse. See "Bulb Replacement" and "Fuses and Circuit Breakers" in the Index. 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. 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. Headlamp High/Low-Beam Changer To change the headlamps from high to low beam, or low to high, simply pull the turn signal lever all the way toward you. Then release it. When the high beams are on, this light on the instrument panel cluster will also be on. Your fog lamps will turn off when you switch to high beams. Using your high beams in fog is not recommended. Flash-to-Pass When the headlamps are off, pull the lever toward you to momentarily switch on the high beams (to signal that you are going to pass). When you release the lever, they will turn off. 2-59
