Lighting When the DRL are on, the regular headlamps, taillamps, sidemarker, and other lamps will not be on. The instrument cluster will also not be lit. The headlamps automatically change from DRL to the regular headlamps depending on the darkness of the surroundings. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. When the DRLs are active and a turn signal is operated, the DRL on the side the turn signal is activated, will turn off until the turn signal is turned off. The regular headlamp system should be turned on when needed. Do not cover the light sensor on top of the instrument panel because it works with the DRL. 6-3 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. If the ignition is turned off with the exterior lamp control in the ; or 5 position, the delayed headlamps cycle will not occur. To disable the delayed headlamps feature or change the time of delay, see Vehicle Personalization on page 5‑37. Adaptive Forward Lighting (AFL) Vehicles with the Adaptive Forward Lighting System (AFL) have headlamps that swivel to the left or right when making a turn to provide better lighting. To enable AFL, set the exterior lamp switch to the AUTO position. Move the switch out of the AUTO position to turn off the system. See Exterior Lamp Controls on page 6‑1. AFL operates when the vehicle speed is greater than 3 km/h (2 mph). AFL does not operate when the transmission is in R (Reverse). AFL is not immediately Delayed Headlamps Delayed headlamps provide a period of exterior lighting as you leave the area around the vehicle. This feature is activated when the headlamps are on due to the automatic headlamps control feature, and when the ignition is turned off. The headlamps remain on until the exterior lamp control is moved to the parking lamps position or until the pre-selected delayed headlamp lighting period has ended.
