Automatic Headlamp System When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with a light sensor on top of the instrument panel, make sure it is not covered or the automatic headlamp system will be on when it is not needed. There is a delay in the transition between the daytime and nighttime operation of the DRL and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp systems will only be affected when the light sensor sees a change in lighting lasting longer than this delay. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave 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, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See "Instrument Panel Brightness Control" under Instrument Panel Brightness on page 185. To idle your vehicle with the automatic headlamp system off, turn the ignition on and set the exterior light switch to the off/on position. For Canadian vehicles, the transaxle must stay in PARK (P) for this function. As with any vehicle, you should turn on the regular headlamps when you need them. 184
