Lighting 6-5 Automatic Headlamp System When the exterior lamp control is set to AUTO and it is dark enough outside, the headlamps come on automatically. The system may also turn on the headlamps when driving through a parking garage or tunnel. When it is bright enough outside, the headlamps will turn off or may change to Daytime Running Lamps (DRL). The automatic headlamp system turns off when the exterior lamp control is turned to O or the ignition is off. Adaptive Forward Lighting (AFL) On vehicles with the AFL system, the headlamps pivot horizontally to provide greater road illumination while turning. To enable AFL, set the exterior lamp control on the turn signal lever to the AUTO position. Moving the control out of the AUTO position will deactivate the system. AFL will operate when the vehicle speed is greater than 3 km/h (2 mph). 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 6‑1. Lights On with Wipers If the windshield wipers are activated in daylight with the engine on, and the exterior lamp control is in AUTO, the headlamps, parking lamps, and other exterior lamps come on. The transition time for the lamps coming on varies based on wiper speed. When the wipers are not operating, these lamps turn off. Move the exterior lamp control to P or ; to disable this feature. There is a light sensor on top of the instrument panel. Do not cover the sensor, otherwise the headlamps will come on when they are not needed.
