Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is complete. If you momentarily press and release the lever, the turn signal will flash three times. If the arrows flash very fast as you signal a turn or a lane change, 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 the fuse. See Fuses and Circuit Breakers on page 428. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam, push the turn signal lever away from you. To change from high beam to low beam, pull the turn signal lever toward you. While the high beams are on, this light located on the instrument panel cluster will also be on. Turn Signal On Chime If your turn signal is left on for more than 0.8 miles (1.3 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. 163
