Lighting The lever returns to its starting position when released. If after signaling a turn or lane change the arrow flashes rapidly or does not come on, a signal bulb may be burned out. Have any burned out bulbs replaced. If the bulb is not burned out, check the fuse. See Fuses and Circuit Breakers on page 10‑38. 6-5 Interior Lighting Instrument Panel Illumination Control The knob for this feature is to the left of the steering column. Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The instrument panel brightness knob extends when D is pressed. To manually turn on the dome lamps, press D then turn the knob clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. Turn Signal On Chime If the turn signal is left on for more than 1.2 km (0.75 mi), a chime sounds at each flash of the turn signal and the message TURN SIGNAL ON also appears in the Driver Information Center (DIC). See Lamp Messages on page 5‑33. To turn off the chime and message, move the turn signal lever to the off position. Dome Lamp Override The E DOME OFF button is above the instrument panel brightness knob. D (Instrument Panel Lights): Push the knob to extend and then turn clockwise or counterclockwise to brighten or dim the instrument panel lights and the radio display. This only works if the headlamps or parking lamps are on.
