Interior Lamps Instrument Panel Brightness This feature controls the brightness of the instrument panel lights. You can brighten or dim the instrument panel lights by turning the exterior lamps control. Turning the control all the way clockwise turns on the courtesy lamps. If the control is turned all the way counterclockwise, the lamps and lights will turn off. 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 RUN or START, so 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. Delayed Entry Lighting Delayed entry lighting lights your vehicle's interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. Just after all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: The ignition is in RUN,or the doors are locked, or an illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on. 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 lamps control all the way clockwise to MAX. Entry Lighting Your courtesy lamps will come on and stay on for a set time whenever you press UNLOCK on the remote keyless entry transmitter. 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. 3-14
