5-4 Lighting Adaptive Forward Lighting (AFL) The Adaptive Forward Lighting System (AFL) pivots the headlamps horizontally to provide greater road illumination while turning. To enable AFL, set the exterior lamp switch on the multifunction lever to the AUTO position. Moving the switch out of the AUTO position will deactivate the system. AFL will operate when the vehicle speed is greater than 2 mph (3 km/h). AFL will not operate when the transmission is in R (Reverse). AFL is not immediately operable after starting the vehicle; driving a short distance is required to calibrate the AFL. See Exterior Lamp Controls on page 5‑1. Hazard Warning Flashers | Hazard Warning Flasher: Press this button located on the instrument panel near the audio system, to make the front and rear turn signal lamps flash on and off. This warns others that you are having trouble. Press again to turn the flashers off. Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it briefly until the lane change is complete. The arrow will automatically flash three times. The lever returns to its starting position when it is 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 the bulbs replaced. If the bulb is not burned out, check the fuse. See Fuses and Circuit Breakers on page 9‑41. Turn Signal On Chime If the turn signal is left on for about 1.6 km (1 mile), a warning chime will sound and the TURN SIGNAL ON message will appear on the Driver Information Center (DIC) display. See "Turn Signal On" under Driver Information Center (DIC) on page 4‑31 for more information. Turn and Lane-Change Signals An arrow on the instrument panel cluster flashes in the direction of the turn or lane change. Move the lever all the way up or down to signal a turn.
