Turn and Lane-Change Signals To signal a turn, move the lever all the way up or down. The lever returns automatically when the turn is complete. An arrow on the instrument panel cluster and in the outside rearview mirror will flash in the direction of the turn or lane change. Arrows that flash rapidly when signaling for a turn or lane change may be caused by a burned out signal bulb. Other drivers will not see the turn signal. Replace burned-out bulbs to help avoid possible accidents. Check the fuse and for burned-out bulbs if the arrow fails to work when signaling a turn. See Fuses and Circuit Breakers on page 5-100. Headlamp High/Low-Beam Changer Push forward to change the headlamps from low beam to high. Pull the lever back and then release it to change from high beam to low. This light on the instrument panel cluster will be on, indicating high-beam usage. 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. The lever returns when it is released. If the turn signal is left on, a warning chime will sound and the Driver Information Center (DIC) will display TURN SIGNAL ON after driving about a mile to remind you to turn it off. 3-10
