3-14 Instrument Panel Adaptive Forward Lighting System Vehicles with the Adaptive Forward Lighting System (AFS) have headlamps that swivel to the left or right when making a turn to provide better lighting. To enable AFS, set the exterior lamp switch to the AUTO position. Move the switch out of the AUTO position to turn off the system. See Exterior Lamps on page 3-12. AFS operates when the vehicle speed is greater than 2 mph (3 km/h). AFS does not operate when the transmission is in R (Reverse). AFS is not immediately operable after starting the vehicle; driving a short distance is required to calibrate the AFS. Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamps button is located on the exterior lamps control to the left of the steering column. Instrument Panel Brightness D (Instrument Panel Brightness): The knob with this symbol on it is located next to the exterior lamps control to the left of the steering wheel. Push the knob in all the way until it extends out and then turn the knob clockwise or counterclockwise to brighten or dim the lights. Push the knob back in when finished. # (Fog Lamps): Press the exterior lamps button to turn the fog lamps on or off. A light comes on in the instrument panel cluster when the fog lamps are in use. The ignition must be on for the fog lamps to work. When the headlamps are changed to high-beam, the fog lamps will turn off. The fog lamps come back on again when the high-beam headlamps are turned off. Some localities have laws that require the headlamps to be on along with the fog lamps. Dome Lamps The dome lamps automatically come on when a door is opened, unless the dome lamp override button is pressed in. The lamps can also be turned on and off by turning the instrument panel brightness control clockwise to the farthest position.
