An arrow on the instrument panel cluster will flash in the direction of the turn or lane change. Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each flash of the turn signal and the message TURN SIGNAL ON will also appear in the DIC. See DIC Warnings and Messages on page 269. To turn the chime and message off, move the turn signal lever to the off position. As you signal a turn or a lane change, if the arrows flash more quickly 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 a blown fuse. See Instrument Panel Fuse Block on page 558 and Underhood Fuse Block on page 561. Headlamp High/Low-Beam Changer 53 (Headlamp High/Low Beam Changer): To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. 207
