System Description [08/2013 - ]

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, license plate lights and side marker lights.

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

• This system has the following functions.

• *1: w/ Side Marker Light

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 engine room junction block assembly. The main body ECU (multiplex network body ECU) transmits a turn on signal to the engine room junction block assembly, which illuminates the high-intensity parking lights.
• This system is enabled when the following conditions are met:
  • Power switch is on (IG)
  • Engine speed signal is input (engine running)
  • Parking brake switch off (w/ Side Marker Light)
  • Light control switch is in the off or AUTO position (and the low beam headlights are not turned on via the automatic light control system). (w/o DRL OFF Switch)
  • Light control switch is in the AUTO position (and the low beam headlights are not turned on via the automatic light control system). (w/ DRL OFF Switch)

The High Intensity Discharge (HID) headlight system uses a discharge bulb as its light source for the low beam. Discharge bulbs are superior to halogen bulbs.

• Discharge bulbs have the following features:
  • The light emitted by the bulb is close in color to sunlight. The light shines ahead over a broader area and further forward, increasing the area visible to the driver.
  • Less power is consumed.
• This system consists of the discharge bulbs and light control ECUs.
• The light control ECU transforms voltage that is received from the auxiliary battery to high voltage of up to 22000 V and applies it to the discharge bulbs in order to illuminate them.

1. General
   • The door mirror foot light system consists primarily of the fade-in/fade-out function and timer illumination function.
   • This control is controlled by the outer mirror control ECU assembly for each mirror and main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends door mirror foot light on/off demand signals to the outer mirror control ECU assembly. According to various information, the outer mirror control ECU assembly performs fade-in/fade-out control of the door mirror foot lights.
2. The door mirror foot light system has the following control functions:

   Function	Outline
   Actuation Area-linked	When all of the following conditions are met, the lights that operate turn on: The power switch is off. All doors are closed. A key is detected in the actuation area.
   	When the following condition is met, the lights that operate turn off: A key is not detected in the actuation area.
   Door Unlock-linked	When all of the following conditions are met, the lights that operate turn on: The power switch is off. All doors are closed. Any door is unlocked when all doors are locked.
   Door Lock-linked	When either of the following conditions is met, the lights that operate turn off: All doors are locked when all doors are closed and any door is unlocked. All doors are locked again when all doors are closed and locked.
   Power Switch-linked	When the following condition is met, the lights that operate turn off: The power switch is on (IG).
   Delay	When approximately 15 seconds elapse after any of the following conditions are met, the lights that operate turn off: An actuation area-linked function is used. The door unlock-linked function is active. Any door is opened and then closed.

1. When the wireless door unlock operation or the entry door unlock operation is performed at nighttime, the parking lights illuminate for 17 seconds.
