There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp system so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor detects a change in lighting lasting longer than the delay. If the vehicle is started in a dark garage, the automatic headlamp system will come on immediately. Once the vehicle leaves the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-16. The parking lamps or low-beam headlamps must be on for the fog lamps to work. The fog lamps will go off whenever the high-beam headlamps come on. When the high beams go off, the fog lamps come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. Exterior Cargo Lamps The cargo lamps can be used if more light is needed in the cargo area of the vehicle or in the top-box storage units. This button is located on the driver side of the instrument panel near the exterior lamp control. Fog Lamps The fog lamp button is located near the exterior lamps control. # : For vehicles with fog lamps, press to turn the fog lamps on or off. An indicator light will turn on in the button when the fog lamps are on. Press to turn the cargo lamps on and off. The dome lamps must be on for the cargo lamps to come on. See Dome Lamp on page 3-16. 3-15
