Lamps/Lighting - Interior (Service Information): Description

The interior lighting system for this vehicle includes both incandescent and Light Emitting Diode (LED) unit lighting on several separate circuits. The lamps in the interior lighting system include:

• Center Floor Console Cup Holder Lamps  - The cup holders in the center floor console include a standard equipment light pipe around their inside perimeter illuminated by LED lamp units to assist visibility at night. These lamps are controlled by the panel lamps dimmer circuit and illuminate whenever the exterior lighting is turned ON.
• Center Floor Console Forward Storage Bin Lamp  - The forward storage bin in the center floor console on some models is illuminated by an LED lamp unit located in the overhead console to assist visibility at night. This lamp is controlled by the exterior lighting circuit and illuminates whenever the exterior lighting is turned ON.
• Center Floor Console Universal Serial Bus Connector Lamp  - The Universal Serial Bus (USB) connector in the center floor console on some models includes an LED lamp unit to assist visibility at night. This lamp is controlled by the courtesy lamp circuit and illuminates whenever the interior courtesy lamps are turned ON.
• Door Entry And Exit Lamps  - Door entry and exit lamps (also known as puddle lamps) on some models include an incandescent lamp unit on the underside of each door trim panel that illuminate the ground outside the opened doors to assist visibility at night. These lamps are controlled by the courtesy lamps circuit and illuminate whenever the interior courtesy lamps are turned ON.
• Door Inside Handle Lamps  - Door inside latch release handle pockets on models with the ambient lighting package include an LED lamp unit to assist visibility at night. These lamps are controlled by both the ambient lamps dimmer circuit and the courtesy lamps circuit. These lamps are illuminated whenever the ambient lighting or the courtesy lighting is turned ON, and are dimmable only when the ambient lighting is turned ON while the exterior lighting is also turned ON.
• Door Map Pocket Lamps  - Door trim panel map pockets on models with the ambient lighting package include an LED lamp unit to assist visibility at night. These lamps are controlled by both the ambient lamps dimmer circuit and the courtesy lamps circuit. These lamps are illuminated whenever the ambient lighting or the courtesy lighting is turned ON, and are dimmable only when the ambient lighting is turned ON while the exterior lighting is also turned ON.
• Front Dome Lamps  - Front seat driver side and passenger side incandescent dome lamps are located behind a lens shared with the LED map/reading lamps in the overhead console. The dome lamps are controlled by the courtesy lamp circuit and by independent lens-actuated switches.
• Front Map/Reading Lamps  - Front seat driver side and passenger side LED map/reading lamps are located behind a lens shared with the incandescent dome lamps in the overhead console. The map/reading lamps are controlled by the courtesy lamp circuit and by independent push button switches in the overhead console.
• Glove Box Lamp  - A standard glove box lamp with an integral plunger-actuated switch is located at the upper outboard corner of the instrument panel lower glove box opening and illuminates whenever the glove box door is opened.
• Instrument Panel Courtesy Lamps  - Vehicles equipped with the optional instrument panel courtesy lamps have two LED lamp units mounted to the closeout panel located under each side of the instrument panel. These lamps are controlled by the courtesy lamps circuit and illuminate whenever the interior courtesy lamps are turned ON.
• Rear Map/Reading Lamps  - Optional rear seat incandescent map/reading lamps are located behind a lens integral to the grab handle unit located on each roof side rail above the door openings. The map/reading lamps are controlled by the courtesy lamp circuit and by independent lens-actuated switches.
• Trunk Lamps  - Standard trunk lamps are located in the right and left trunk trim panels and are activated automatically whenever the decklid is opened to illuminate the trunk of the vehicle.
• Vanity Lamps  - Optional single-intensity vanity lamps are located on both sides of a covered mirror on both the right and left sun visors. These lamps are controlled by an integral vanity mirror cover-actuated switch.

Most controls on the instrument panel and elsewhere in the interior of the vehicle are illuminated by the panel lamps dimmer circuit for night visibility. All have miniature incandescent bulbs, LED units or a combination of the two lighting types that are soldered to internal circuit boards and are not serviceable.

Other components of the interior lighting system for this vehicle include:

• Body Control Module  - The Body Control Module (BCM) is located beneath the instrument panel on the passenger side of the vehicle. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION .
• Dimmer Module  - A dimmer module is located on the left side of the instrument panel, below and outboard of the steering column just inboard from the headlamp switch. The dimmer module features a vertical thumbwheel for selecting the panel lamps dimming level, a PARADE mode to illuminate all Vacuum Fluorescent Display (VFD) units at full brightness for visibility when driving in daylight with the exterior lighting turned ON. There are also detent positions to turn ON all interior courtesy lighting, and a DEFEAT position that overrides door ajar switch control of interior lighting. On vehicles equipped with the ambient lighting option the dimmer module includes a second thumbwheel dedicated to the ambient lighting, which allows the selection of the ambient lighting dimming level while the exterior lighting is turned ON and includes a detent position that turns the ambient lighting OFF.
• Door Ajar Switches  - A door ajar switch is integral to the door latch mechanism of each door.
• Door Module  - An electronic door control module is concealed behind the front door trim panel where it is secured through two integral mounting tabs to the inner door panel. Refer to MODULE, DOOR (DDM/PDM), DESCRIPTION .
• Trunk Ajar Switch  - A trunk ajar switch is integral to the decklid latch mechanism.
