Interior Lighting
Interior Lighting
The interior lighting system consists of the following components:
- Interior/map lamps
- Luggage compartment lamp
- Door ajar switches (integrated into the door latches)
- Luggage compartment lid/liftgate ajar switch (integrated into the luggage compartment lid/liftgate latch)
- Ambient lighting module (located under the center console)
- Ambient lighting switch (integrated into the passenger heated seat switch)
- Body Control Module (BCM)
The interior lighting system consists of up to 3 subsystems:
- Courtesy lamps
- Demand lamps
- Ambient lighting
Battery Saver
NOTE: Time-out is 10 seconds if the vehicle is in Factory mode or 0 seconds if the vehicle is in Transport mode.
The provides automatic shut-off of the courtesy and demand lamps after a time-out period when the ignition is OFF. A timer in the BCM (Body Control Module) starts when any of the following occur:
- the ignition is changed to OFF
- any door or luggage compartment lid/liftgate becomes ajar
- the UNLOCK button of the transmitter is pressed
- a door is unlocked using a key
- the door lock switch is pressed
When 10 minutes (30 minutes for demand lamps) have elapsed, the automatically shuts the voltage off to the lamps. The timer restarts (voltage is restored if the BCM (Body Control Module) is in battery saver mode) if any of the following occurs:
- the ignition is changed out of OFF
- any door, luggage compartment lid or liftgate becomes ajar
- the UNLOCK button of the transmitter is pressed
- a door is unlocked using a key
- the door lock switch is pressed
Courtesy Lamps
The courtesy lamp subsystem consists of the interior/map lamps, the door ajar switches and the BCM (Body Control Module). The turns the courtesy lamps on when a door is opened or when an unlock signal is received from the Remote Keyless Entry (RKE) transmitter.
Illuminated Entry/Exit
The illuminated entry and exit features provide temporary illumination of the parking lamps, the dimmable backlighting, the ambient backlighting and the courtesy lamps. Refer to the following table for additional information.
NOTE: An arbitrator (software programming) within the determines which actions take precedence over others (for example, an open door keeps the courtesy lamps on even when a command to lock the doors is received).
NOTE: For vehicles without Intelligent Access (IA), the timer for the backlighting and ambient lighting is reset to 25 seconds when the key is inserted or removed from the ignition lock cylinder.
Theater Lighting
The theater lighting option ramps-up the courtesy lamps over 0.7 second when courtesy lamp activation is requested. The theater lighting feature ramps-down the courtesy lamps over 1.7 seconds when interior lighting deactivation is requested by any feature other than the panic alarm or battery saver.
Demand Lamps
The demand lamps subsystem consists of the map/reading lamps and the luggage compartment lamp (sedan) or cargo lamp (5-door) lamp. The energizes the battery saver relay to supply voltage to the demand lamps when the battery saver feature is not active.
Ambient Lighting
The ambient lighting LEDs illuminate the cup holders (front and rear) and the front and rear footwell areas. The ambient lighting subsystem consists of the ambient lighting switch, the ambient lighting module, and the harness with hardwired LEDs located within the floor console and under the instrument panel footwell areas. The ambient lighting is operational when the ignition is in any state other than OFF (the exception is when it is used in conjunction with the illuminated entry/exit features). The ambient lighting switch cycles the LEDs through 7 different color combinations or to turn the ambient lighting off.
