Lexus NX: Automatic High Beam

The Automatic High Beam uses an in-vehicle camera sensor to assess the brightness of streetlights, the lights of oncoming and preceding vehicles, etc., and automatically turns high beam on or off as necessary.

WARNING

■Limitations of the Automatic High Beam Do not rely on the Automatic High Beam. Always drive safely, taking care to observe your surroundings and turning high beam on or off manually if necessary.

1. Push the lever away from you with the headlight switch in or position.

2. Press the Automatic High Beam switch.

The Automatic High Beam indicator will come on when the headlights are turned on automatically to indicate that the system is active.

■Camera sensor detection information

• High beam may not be automatically turned off in the following situations:
  • When oncoming vehicles suddenly appear from a curve
  • When the vehicle is cut in front of by another
  • When oncoming or preceding vehicles are hidden from sight due to repeated curves, road dividers or roadside trees
• High beam may be turned off if an oncoming vehicle that is using fog lights without using the headlights is detected.
• House lights, street lights, red traffic signals, and illuminated billboards or signs may cause the high beam to turn off.
• The following factors may affect the amount of time taken to turn high beam on or off:
  • The brightness of headlights, fog lights, and tail lights of oncoming and preceding vehicles
  • The movement and direction of oncoming and preceding vehicles
  • When a oncoming or preceding vehicle only has operational lights on one side
  • When a oncoming or preceding vehicle is a two-wheeled vehicle
  • The condition of the road (gradient, curve, condition of the road surface, etc.)
  • The number of passengers and amount of luggage
• High beam may be turned on or off when unexpected by the driver.
• In the situations below, the system may not be able to correctly detect the surrounding brightness levels, and may flash or expose nearby pedestrians to the high beam. Therefore, you should consider turning the high beams on or off manually rather than relying on the Automatic High Beam system.
  • In bad weather (rain, snow, fog, sandstorms, etc.)
  • The windshield is obscured by fog, mist, ice, dirt, etc.
  • The windshield is cracked or damaged.
  • The camera sensor is deformed or dirty.
  • The camera sensor temperature is extremely high.
  • Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
  • Vehicles ahead have headlights or tail lights that are either switched off, dirty, are changing color, or are not aimed properly.
  • When driving through an area of intermittently changing brightness and darkness.
  • When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks, etc.).
  • When frequently and repeatedly taking curves or driving on a winding road.
  • There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
  • The back of a vehicle ahead is highly reflective, such as a container on a truck.
  • The vehicle's headlights are damaged or dirty.
  • The vehicle is listing or titling, due to a flat tire, a trailer being towed, etc.
