Lighting System

(a) Illumination control system (Illuminated entry system):

When the doors are unlocked through a key or transmitter operation, or when a door is opened or closed, the illuminated entry system turns on the room light assembly.

(1) The main body ECU receives the following signal (A).

• Door courtesy switch signal

• Door detection switch signal

• Ignition switch signal

(2) The main body ECU controls the following signal based on the signals listed in A.

• Illumination operation signal

(3) The main body ECU controls the on/off and fade-in/fade-out operation of the following parts.

• Room light assembly

(b) Battery saver system:

When the ignition switch is turned off and the any of the doors is open continuously for 20 minutes, the main body ECU turns the illumination operation signal off. As a result, the room light assembly, taillights, and the headlights turn off.

(1) The main body ECU receives the following signals (B).

• Door courtesy switch signal

• Ignition switch signal

(2) The main body ECU controls the following signal based on the signals listed in B (C).

• Illumination operation signal

(3) The main body ECU controls the illumination period of the following parts based on the signals listed in C.

• Room light assembly

• Position light (Front and Rear)

(c) Manual light control system:

This system functions when lights such as the headlights and taillights are illuminated through manual operation of the light control switch.

(1) The main body ECU receives the following signals (D).

• Light control switch signal

• Headlight dimmer switch signal

• Front fog light switch signal

(2) The main body ECU controls the following signals based on the signals listed in D (E).

• H-LP/AMT relay operation signal

• T-LP relay operation signal

• Running light relay assembly operation signal

• Front fog light relay operation signal

(3) The main body ECU controls the on/off operation of the following parts based on the signals listed in E.

• Position light (Front and Rear)

• Front fog light Light auto turn off system:

When the headlights and taillights are illuminated through the operation of the automatic light control switch, if the ignition switch is turned off and all doors are closed, this system continues illuminating the headlights and taillights for approximately 30 seconds, and then turns off the lights. However, when all the doors locked manually, using the door lock button or using the key or pressing the LOCK on the wireless remote turns the headlights and taillights off immediately.

(1) The main body ECU receives the following signals (F).

• Door courtesy switch signal

• Ignition switch signal

(2) The main body ECU controls the following signals based on the signals listed in F (G).

• H-LP/AMT relay operation signal

• T-LP relay operation signal

• Running light relay assembly operation signal

• Front fog light relay operation signal

(3) The main body ECU controls the illumination period of the following parts based on the signals listed in G.

• Position light (Front and Rear)

• Front fog light Daytime running light system:

This system is directly connected to the low-beam headlights and is designed to automatically activate the daytime running lights in order to increase the visibility of the vehicle.

(1) The main body ECU receives the following signals (I).

• Ignition switch signal

• Generator signal

• Parking brake switch signal

• Light control switch signal

(2) The main body ECU controls the following signal based on the signals listed in I.

• Running light relay assembly operation signal
