Interior Lamps Control Entry Lighting The entry lighting system turns on the courtesy lamps and the backlighting to the door switches and to the exterior lamp control when a door is opened or if you press the remote keyless entry transmitter unlock button. If activated due to the transmitter, the lighting will remain active for about 40 seconds. Since the entry lighting system uses the light sensor, it must be dark outside in order for the courtesy lamps to turn on. The courtesy lamps turn off approximately 25 seconds after the last door is closed. They will dim to off if the ignition key is placed in ON, or immediately deactivate if the power locks are activated. When the interior lamp lever is in OFF, the lamps are turned off. Only the driver's door controls and ignition switch backlighting functions will operate. If the lever is in AUTO and a front door is opened, the overhead console light, front hush panel lamps and rear footwell lamps in the door will automatically come on. When the rear door is opened, all the front door lighting and rear overhead lamps will come on. When the lever is in ON,the courtesy lamps are turned on. Also, all automatic interior lighting functions are terminated. Parade Dimming This feature prohibits dimming of the digital displays and backlighting during daylight hours when the key is in the ignition and the headlamps are on. This feature operates with the light sensor for the Twilight Sentinel@ and fully automatic. When the light sensor is reads darkness outside and the parking lamps are active, the digital displays can be adjusted by turning the instrument panel brightness knob counterclockwise to dim and clockwise to brighten lighting. 3-20
