As you signal a turn or a lane change, if the arrows don't flash but just stay on, a signal bulb may be burned out and other driverswon't see your turn signal. Headlamp Highkow 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 on the instrument panel also will be on. If a bulb is burned out, replace it tohelp avoid an accident. If the arrows don't go on at all when you signal a turn, check the fuse (see "Fusesand Circuit Breakers" in the Index) and for burned-out bulbs. If you have a trailertowing option with added wiring for the trailer lamps, a different turn signal flasher isused. With this flasher installed, the signal indicator will flash even if a turn signal bulbis burned out. Check the front and rear turn signal lamps regularly to make sure they are working. 2-37
