Courtesy/Reading Lamp

Courtesy lamps can be turned on by pressing the headlamp switch in, by opening any door or by pressing the unlock button on a keyless entry remote transmitter. A theater lighting feature gradually increases the light intensity ON and OFF when switched by opening or closing a door.

The following lamps illuminate for courtesy lighting:
- instrument panel courtesy (foot) lamps
- front dome/map lamps (LH and RH)
- rear reading lamps (LH and RH)

Operation is as follows:
- Demand lighting includes courtesy lamps that are illuminated by directly or indirectly actuating a switch.
- The front dome/map lamps are located in the overhead console.
- Each lamp is controlled by its own switch.

The following demand lamps are provided with battery positive voltage (B+) by the demand lighting output of the Lighting Control Module (LCM). Each has a dedicated switch that closes to ground to illuminate the lamp:
- glove compartment lamp
- vanity mirror lamp
- luggage compartment lamp

The following lamps are also part of the courtesy lighting function:
- front map lamps (LH and RH)
- rear reading lamps (LH and RH)

The front map lamps are powered by either the demand lighting circuit or the courtesy lighting circuit, depending upon the position of the switch associated with each lamp.
- When the customer turns the RH front map lamp switch ON, the front map lamp is illuminated through power supplied by the LCM demand lighting circuit.
- If the customer turns the map lamp switch OFF, the power from the LCM demand lighting circuit is interrupted and the lamp is reconnected to the courtesy lighting circuit.

The rear reading lamps are powered by either the courtesy lighting circuit or the demand lighting circuit.
- When the customer turns the rear reading lamp switch ON, the rear reading lamp is illuminated through power supplied by the LCM demand lighting circuit.
- If the customer turns the rear reading lamp switch OFF, the power from the LCM demand lighting circuit is interrupted and the lamp is reconnected to the courtesy lighting circuit.

Interior lamp is located at the top and center of the back window glass in the roof headlining. The interior lamp is controlled by independently operated switches or with the dome lamp functions.
