Interior Lamps Instrument Panel Brightness Control You can brighten or dim the instrument panel and cluster lights by turning the exterior lamp knob. Turn the knob clockwise to increase the brightness of the instrument panel and cluster, and counterclockwise to decrease the brightness. Your parking lamps must be on for this feature to work. Illuminated Entry (If Equipped) Your courtesy lamps will come on and stay on for a set time whenever you press UNLOCK on the remote keyless entry transmitter (if equipped). If you open a door, the lamps will stay on while it's open and then turn off automatically about 25 seconds after you close it. If you press UNLOCK and don't open a door, the lamps will turn off after about 40 seconds. Illuminated entry includes a feature called theater dimming. With theater dimming, the lamps don't just turn off at the end of the delay time. Instead, they slowly dim after the delay time until they go out. The delay time is canceled if you turn the ignition key to ON or press the power door lock switch. The lamps will dim right away. When the ignition is on, illuminated entry is inactive, which means the courtesy lamps won't come on unless a door is opened. Courtesy Lamps When any door is opened, several lamps come on. These lamps are courtesy lamps. They make it easy for you to enter and leave your vehicle. You can also turn these lamps on by turning the exterior lamp knob all the way clockwise. Some of the lamps have switches so you can turn them on, even when the doors are closed. These lamps are reading lamps. 2-55
