The DRL system will be off any time your vehicle is in PARK (P). The DRL system on U.S. vehicles can also be turned off by using the off/on switch for one ignition cycle. As with any vehicle, you should turn on the regular headlamp system when you need it. There is a delay in the transition between the daytime and nighttime operation of the automatic lamp control system so that driving under bridges or bright overhead street lights does not affect the system. The automatic lamp control system 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 lamp system will come on immediately. Once you leave the garage, it will take about one minute for the automatic lamp 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 on page 3-19. To idle your vehicle with the system off, turn the ignition on and rotate 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. Automatic Headlamp System When it is dark enough outside, your automatic system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps, instrument panel lights, and interior switch backlighting. Your vehicle has a light sensor on top of the instrument panel. Make sure it is not covered, or the headlamps may remain on when you do not need them. The system may also be on when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. 3-18
