LIGHTING (EXT): LIGHTING SYSTEM: SYSTEM DESCRIPTION
1. AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL SYSTEM
* When the headlights are on, the automatic headlight beam level control system operates the headlight level actuator in accordance with the movement of the vehicle.
* The automatic headlight beam level control system mainly consists of the AFS ECU, front and rear height control sensors, and 2 headlight level actuators.
* For vehicles with the air suspension system, the AFS ECU calculates changes in the vehicle posture based on the signals from the air suspension ECU and each ECU. Then the AFS ECU controls the headlight level actuator based on this information, in order to change the headlight reflector angle.
2. AFS
* An intelligent AFS (Adaptive Front-lighting System) is used in order to ensure a wide low beam lighting area and realize excellent visibility during turns by moving the low beam.
* The intelligent AFS of this vehicle uses medium-to-high speed control. During medium-to-high speed control, the system calculates the target lighting angle based on the tire angle and vehicle speed, and changes the swivel angle of the low beam headlights independently.
3. ILLUMINATED ENTRY SYSTEM
* The illuminated entry system of this vehicle controls 8 kinds of lights: engine switch illumination, interior foot light illumination, seat belt buckle switch illumination, courtesy lights, step light, door inside handle illumination light, interior lights (for front and rear) and door mirror foot lights.
* The main body ECU controls this system.
4. INTERIOR LIGHT CONTROL
The interior light control (front interior light, engine switch illumination) consists primarily of the fade-in/fade-out function and timer illumination function.
5. INTERIOR FOOT LIGHT ILLUMINATION CONTROL AND DOOR INSIDE HANDLE ILLUMINATION LIGHT CONTROL
The interior foot light illumination control and door inside handle illumination light control consist primarily of the fade-in/fade-out function and timer illumination function.
6. DOOR MIRROR FOOT LIGHT CONTROL
The door mirror foot light control consists primarily of the fade-in/fade-out function and timer illumination function.
7. BATTERY SAVING CONTROL
When the following condition has been met, battery saving control turns off the illuminated lights.
* With a door open and the engine not running, approximately 20 minutes elapse.
8. AUTOMATIC LIGHT CONTROL SYSTEM
* When the light control switch is in the AUTO position, the automatic light control system detects ambient light levels and controls the headlights and taillights (parking lights, taillights and license plate light).
* Ambient light levels are detected by the light control sensor that is integrated into the front solar sensor of the air conditioning system.
* The main body ECU controls this system.
9. LIGHT AUTO TURN OFF SYSTEM
* The light auto turn off system is used to prevent the driver from leaving the vehicle with the exterior lights (headlights, fog lights, taillights and license plate light) on.
* This system turns all exterior lights off approximately 30 seconds after either of the following conditions is met:
* The driver door is opened.
* The engine switch is turned off, all the doors are closed and the luggage compartment door is opened and closed with all exterior lights on.
* This system turns all exterior lights off immediately when the lock button on the wireless remote control is pushed with all the doors locked or unlocked.
* When the engine switch is turned off and the driver door is opened with exterior lights other than the headlights on, this system turns them off.
10. DAYTIME RUNNING LIGHT SYSTEM
(a) This system 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 (H).
* Engine switch signal
* Engine speed signal
* Parking brake switch signal
* Light control switch signal
(2) The main body ECU controls the following signal based on the signals listed in H (I).
* Daytime running light relay operation signal
(3) The main body ECU controls the on/off operation of the following part based on the signal listed in I.
* Headlight assembly (high-beam)
