The system may also turn on theheadlamps when driving through aparking garage or tunnel.
There is a delay in the transitionbetween the daytime and nighttimeoperation of the Daytime RunningLamps (DRL) and the automaticheadlamp system so that drivingunder bridges or bright overheadstreet lights does not affect thesystem. The DRL and automaticheadlamp system are only affectedwhen the light sensor sees achange in lighting lasting longerthan the delay.
If the vehicle is started in a darkgarage, the automatic headlampsystem comes on immediately.Once the vehicle leaves the garage,it takes approximately 30 secondsfor the automatic headlamp systemto change to DRL if it is lightoutside. During that delay, theinstrument cluster may not be as
bright as usual. Make sure theinstrument panel brightness controlis in the full bright position. SeeInstrument Panel IlluminationControl0129.
