System Description

WARNING: This page is about a different variant/trim than selected.

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 low beam headlights, parking lights, taillights, marker lights and license plate lights.

LIGHT AUTO TURN-OFF SYSTEM

The light auto turn-off system is used to prevent the exterior lights from being accidentally left on (low beam headlights, high beam headlights, front fog lights, taillights, parking lights, license plate lights and marker lights).

This system has the following functions.

Function	Outline
Driver Door-linked Function	The exterior lights automatically turn off when all of the following conditions are met: The power switch is turned from on (IG) to off. The light control switch is in the tail position. The driver door is opened.
Delay Function	The exterior lights automatically turn off after 30 seconds when all of the following conditions are met: The power switch is turned from on (IG) to off. The low beam headlights are on (light control switch is in the head or AUTO position). All doors are closed after any of the doors are opened.
Door Control Transmitter-linked Function	The exterior lights turn off immediately when the delay function is active and the following condition is met: The lock button on the key is pushed after all doors are locked. HINT: The delay function can not be cancelled when the remote A/C switch on the key is pressed to lock all of the doors.

DAYTIME RUNNING LIGHT SYSTEM (for Canada)
The daytime running light system is designed to automatically illuminate the daytime running lights during the daytime to make the vehicle more visible to other vehicles.
- This system is controlled by the main body ECU (multiplex network body ECU) and daytime running light relay. The main body ECU (multiplex network body ECU) transmits a turn ON signal to the daytime running light relay, which illuminates the high beam headlights using duty control.
- This system is enabled when the following conditions are met:
  - Power switch is on (IG).
  - READY condition signal is received.
  - Parking brake switch is off.
  - Light control switch is in the off, tail or AUTO position (and the low beam headlights are not turned on via the automatic light control system).
DAYTIME RUNNING LIGHT SYSTEM (except Canada)
The daytime running light system is designed to automatically illuminate the daytime running lights during the daytime to make the vehicle more visible to other vehicles.
- This system is controlled by the main body ECU (multiplex network body ECU) and daytime running light relay. The main body ECU (multiplex network body ECU) transmits a turn ON signal to the daytime running light relay, which illuminates the daytime running lights.
- This system is enabled when the following conditions are met:
  - Power switch is on (IG).
  - READY condition signal is received.
  - Parking brake switch is off.
  - Light control switch is in the tail or DRL position (w/o Automatic Light Control).
  - Light control switch is in the tail or AUTO position (and the low beam headlights are not turned on via the automatic light control system) (w/ Automatic Light Control).

LED HEADLIGHT SYSTEM

General
LED headlights are used to provide efficient, maintenance free lighting. Compared to halogen or HID headlights, even if an LED headlight is used for a long time, the reduction of brightness over its lifetime is less. In addition, there is no possibility of an LED having an open circuit because of vibration.

Function of Main Components

Component		Outline
Light Control ECU		Turns on the LEDs immediately when the light control switch is turned to the head position. Regulates the output current flowing into the LEDs at a specified level to prevent the light from getting brighter and dimmer due to voltage variation. Transmits fail signals to the main body ECU (multiplex network body ECU) when a malfunction occurs in the LED headlight system.
Combination Meter Assembly	Master Warning Light	Flashes to inform the driver when the light control ECU detects malfunctions in this system.
Combination Meter Assembly	Multi-information Display	Displays a warning message to inform the driver when the light control ECU detects a malfunction in this system.
Main Body ECU (Multiplex Network Body ECU)		Receives fail signals from the light control ECU when a malfunction occurs in the LED headlight system, and transmits the signals to the combination meter assembly. Stores Diagnostic Trouble Codes (DTCs) when the system malfunctions.
