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.

Driving and Operating 197
During any of these fault conditions,the display will be blank and theindicator will flash while the vehicleis in R (Reverse) or until theconditions return to normal.
Parking Assist
If equipped, the Rear Parking Assist(RPA) system uses sensors on therear bumper to assist with parkingand avoiding objects while inR(Reverse).
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with parking assist,
always check the area around the
vehicle and check all mirrors
before backing.
How the System Works
RPA comes on automatically whenthe shift lever is moved intoR(Reverse). A single beep soundsto indicate the system is working.
RPA operates only at speeds lessthan 8 km/h (5 mph).
An obstacle detection is indicatedby beeps. The time between beepsgets shorter as the vehicleapproaches the obstacle. Repeatedbeeps are heard when the distanceis less than 30 cm (12 in).
To b e d e t e c t e d , o b j e c t s m u s t b e a tleast 25 cm (10 in) off the groundand below rear door level. Objectsmust also be within 2.5 m (8 ft) fromthe rear bumper. This distance maybe less during warmer or humidweather.

The system can be disabled throughthe Driver Information Center (DIC).See“Park Assist”underDriverInformation Center (DIC)0108.
RPA defaults to the on setting eachtime the vehicle is started.
