To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically. A green arrow on the instrument panel will flash in the direction of the turn or lane change. If a bulb is burned out, replace it to help avoid an accident. If the green arrows don't go on at all when you signal a turn, check the fuse (see "Fuses" in the Index) and for burned-out bulbs. Turn Signal "ON" Chime A chime will sound if your turn signal is left on after having gone 3/4 mile, to remind you to turn your signal off. Operation of Lights Although your vehicle's lighting system (headlights, parking lights, fog lamps, side marker lights and taillights) meet all applicable federal lighting requirements, certain states and provinces may apply their own lighting regulations that may require special attention before you operate theselights. For example, some jurisdictionsmay require that you operate your lower beam lights with fog lamps at all times, or that headlights be turned on whenever you must use your windshield wipers. In addition, most jurisdictions prohibit driving solely with parking lights, especially at dawn or dusk. It is recommended that you check with you own state orprovincial highway authority for applicable lighting regulations. To signal a lane change, just raise or lower the lever until the green arrow starts toflash. 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, the arrows don't if flash but just stay on, a signal bulb may be burned out and other drivers won't see your turn signal. 82
