Automatic Headlamp
System
When it is dark enough outside andthe headlamp switch is in AUTO,the automatic headlamp systemturns on the headlamps, along withthe taillamps, sidemarker lamps,parking lamps, and the instrumentpanel lights. The radio lights willalso be dim.
To t u r n o f f t h e a u t o m a t i c h e a d l a m psystem, turn the exterior lampcontrol to the off position and thenrelease. For vehicles first sold inCanada, the transmission must bein the P (Park) position, before theautomatic headlamp system can beturned off.
The vehicle has a light sensor onthe top of the instrument panel. Donot cover the sensor; otherwise thesystem will come on whenever theignition is on.
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.

Windshield Wipers
If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.
Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before using thewindshield wipers.
If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.
Fuses and Circuit
