Interior Lighting

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The interior lighting system consists of the following components:

- SJB
- Instrument panel dimmer switch
- Interior/map lamps
- Luggage compartment lamp
- Vanity mirror lamps
- Puddle lamps (if equipped)
- Door ajar switches
- Luggage compartment lid ajar switch
- Ambient lighting module (if equipped)

The interior lighting system consists of up to 3 subsystems:

- Courtesy lamps
- Demand lamps
- Ambient lighting (if equipped)

Courtesy Lamps

The courtesy lamp subsystem consists of the interior dome lamps, luggage compartment lamp, and the puddle lamps (if equipped). The courtesy lamps illuminate as a system when requested by the SJB during such conditions as an open vehicle door.

Demand Lamps

The demand lamps subsystem consists of the front map lamps and the left and right vanity mirror lamps. The demand lamps illuminate individually when the vehicle occupant activates them.

Ambient Lighting

The demand lamps subsystem consists of the front map lamps and the left and right vanity mirror lamps. The demand lamps illuminate individually when the vehicle occupant activates them.

- Ambient lighting switch (located in the center console)
- Ambient lighting module (located in the center console)
- LEDs (hardwired in the ambient lighting electrical harness)
- located on the center console cupholders, the storage bin, and the front and rear footwells

The ambient lighting system is powered through the accessory delay relay.

Interior Lighting Delay

The interior lighting delay feature provides temporary illumination of the courtesy lamps after the doors are opened and then closed. The interior lighting delay feature will keep the courtesy lamps on for a period of 25 seconds. If during the 25-second delay time the SJB detects that the ignition has been turned on, or if the vehicle is locked using the Remote Keyless Entry (RKE) transmitter or the keyless entry keypad, the courtesy lamp illumination will be discontinued.

Illuminated Entry

The illuminated entry feature illuminates the courtesy lamps when the ignition is off and either the RKE transmitter UNLOCK button is pressed, or the vehicle is unlocked using the keyless entry keypad. The illuminated entry feature turns the courtesy lamps off when 25-seconds have elapsed, the ignition is switched to on, the RKE transmitter LOCK button is pressed, or the vehicle is l7ocked using the keyless entry keypad.

Illuminated Exit

The illuminated exit feature illuminates the courtesy lamps for 25 seconds when all doors are closed and the ignition key is removed from the ignition lock cylinder. The illuminated exit feature turns the courtesy lamps off when the ignition key is inserted into the ignition lock cylinder or 25 seconds have elapsed.

Theater Lighting (MKZ Only)

The theater lighting feature ramps-up the courtesy lamps intensity over 0.7 seconds when courtesy lamp activation is requested. The theater lighting feature ramps-down the courtesy lamps intensity over 1.7 seconds when interior lighting deactivation is requested by any feature other than the panic alarm or battery saver.
