Courtesy Lamps The courtesy lamps are located on the headliner above the rear seat. These lamps come on by turning the instrument panel brightness knob fully clockwise or when any door is opened and it is dark outside. Puddle lamps are located on the bottom of the front and rear door trim. 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 is fully automatic. When the light sensor 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. Entry Lighting This feature 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. 3-21
