Automatic Headlamp System Your vehicle is equipped with an automatic light sensor on top of the instrument panel, on the passenger's side of the vehicle, so be sure it is not covered. If it is, the headlamps will remain on continuously. There is a delay in the transition between the daytime and nighttime operation of the DRL and the Automatic Headlamp Systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and Automatic Headlamp Systems will only be affected when the light sensor sees a change in lighting lasting longer than this delay. When it is dark enough outside, or you are driving through a parking garage, heavy overcast weather or a tunnel, the system will turn on your low-beam headlamps at normal brightness. Along with your vehicle's headlamps, the taillamps, sidemarker, parking lamps and the instrument panel lights will also turn on. The radio display will dim. As with any vehicle, you should turn on the regular headlamps when you need them. To temporarily disable your vehicle's DRL and Automatic Headlamp Systems functions, do the following: 1. Before turning the ignition key to ON or START, set the parking brake. 2. Then turn the ignition key to ON or START. • The Automatic Headlamp System will not turn on under any conditions, even in darkness. • The DRL will not turn on. The DRL and Automatic Headlamp System functions will stay off with the ignition on, until you release the parking brake. Once the parking brake is released the DRL will turn on if it is daylight or the Automatic Headlamp System will turn on if it is dark enough outside. If you turn the ignition key to ON or START and then set the parking brake, the DRL will turn off (in all conditions) and the Automatic Headlamp System will remain on (if dark enough outside). Any other uses of the parking brake after the engine is turned on will have no effect on the normal Automatic Headlamp System operation. Headlamps On Reminder If you turn the ignition off, remove the key, open the door and leave the lamps on, a tone will remind you to turn off your lamps. 3-15
