When it is dark enough outside, the exterior lamps will come on automatically. When it is bright enough outside, the exterior lamps will turn off and the DRL will turn on. Of course, you may still turn on the headlamps any time you need to. 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 approximately 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 Interior Lamps on page 3-17. To idle your vehicle with the DRL and automatic headlamp control off, set the parking brake while the ignition is in OFF or LOCK. Then start the vehicle. The DRL and automatic headlamp control will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it. Fog Lamps Your vehicle may have fog lamps. If it does, the fog lamps switch is located in the instrument panel switchbank. Press the fog lamp symbol on the switch to turn on the lamps. The indicator light will be lit while the fog lamps are on. Press the top part of the switch to turn them off. When your DRL are on, the exterior lamps control must first be turned from the off position before the fog lamps can be turned on. Your parking lamps or headlamps must be on for your fog lamps to turn on. At night, when the light sensor automatically turns on your headlamps, the fog lamps can be turned on while the exterior lamps control is in any position. Your fog lamps will go off when you switch to high beams. Using your high beams in fog is not recommended. 3-16
