Adaptive LED Headlights (ALH) (Some Models)

The Adaptive LED Headlights (ALH) are a system which uses the Forward Sensing Camera (FSC) to determine the situation of a vehicle ahead or a vehicle approaching in the opposite direction while driving at night to automatically switch the illumination range of the headlights, the illuminated area, or the illumination brightness.

Refer to Forward Sensing Camera (FSC) (Search).

The Adaptive LED Headlights (ALH) are controlled between high and low beams as follows to assure the driver’s visibility without dazzling a vehicle ahead or a vehicle approaching in the opposite direction.

Glare-Free High Beam

This feature dims only the high-beam light shone on the vehicle ahead.

The high beams will dim while driving at a speed of about 40 km/h (25 mph) or faster. When the vehicle speed is less than about 30 km/h (18 mph), the beams switch to the low beams.

 


The headlight high-beam indicator light turns on while the high beams are on.

Close Note

Wide-Range Low Beam

This feature extends the illumination range of the light cast by the low beams while driving at a speed less than about 40 km/h (25 mph).

Highway Mode

This feature shifts the illumination angle of the light cast by the headlights upward while driving on highways.

The distance in which the Adaptive LED Headlights (ALH) can detect objects varies depending on the surrounding conditions.

 


  • Do not modify the suspensions or headlight units, or remove the camera. Otherwise, the Adaptive LED Headlights (ALH) may not operate normally.

  • Do not rely excessively on the Adaptive LED Headlights (ALH) and drive the vehicle while paying sufficient attention to safety. Switch the headlights between the high beams and low beams manually if necessary.

Close Caution

 


Under the following conditions, the Adaptive LED Headlights (ALH) may not operate normally. Manually switch between the high and low beams according to the visibility, and the road and traffic conditions.

  • When there are other sources of light in the area such as street lamps, illuminated signboards, and traffic signals.

  • When there are reflective objects in the surrounding area such as reflective plates and signs.

  • When visibility is reduced under rain, snow and foggy conditions.

  • When driving on roads with sharp curves or undulations.

  • When the headlights/rear lamps of vehicles ahead or in the opposite lane are dim or not illuminated.

  • When there is insufficient darkness such as at dawn or dusk.

  • When the luggage compartment is loaded with heavy objects or the rear passenger seats are occupied.

  • When visibility is reduced due to a vehicle ahead spraying water from its tyres onto your windscreen.

To Operate the System

The system switches the headlights to the high beams after the ignition is switched ON and the headlight switch is in the position. The Adaptive LED Headlights (ALH) indicator light (green) in the instrument cluster turns on simultaneously.

The Adaptive LED Headlights (ALH) determine that it is nighttime based on the brightness of the surrounding area.

The system cancels operation when the headlight switch is turned to a position other than , the headlights are manually switched to low beams, or the high beams are flashed on and off.

 


The system can be changed so that the Adaptive LED Headlights (ALH) do not operate.

Refer to Personalisation Features (Search).

Close Note

Manual Switching

Switching to low beams

Shift the lever to the low beam position.

The Adaptive LED Headlights (ALH) indicator light (green) turns off.

Switching to high beams

Turn the headlight switch to the position.

The Adaptive LED Headlights (ALH) indicator light (green) turns off and the is illuminated.
