After selecting 'High Beam Assist' in the Settings menu, High Beam Assist will operate by following the procedure below.

  • Place the headlamp switch in the AUTO position and push the headlamp lever towards the instrument cluster. The High Beam Assist (illuminate on the cluster and the ) indicator light will illuminate on the cluster and the system will be enabled.
  •  When the system is enabled, high beam will turn on when vehicle speed is above 25mph (40km/h).

    When vehicle speed is below 15mph (25km/h), high beam will not turn on.

  • The High Beam (light ) indicator light will illuminate on the cluster when high beam is on.

When High Beam Assist is operating, if the headlamp lever or switch is used, the system operates as follow:

  • If the headlamp lever is pulled towards you when the high beam is off, the high beam will turn on without High Beam Assist canceled.

    When you let go of the headlamp lever, the lever will move to the middle and the high beam will turn off.

  • If the headlamp lever is pulled towards you when the high beam is on by High Beam Assist, low beam will be on and the system will turn off.
  • If the headlamp switch is placed from AUTO to another position (headlamp/position/off), High Beam Assist will turn off and the corresponding lamp will turn on.

When High Beam Assist is operating, high beam switches to low beam if any of the following conditions occur:

  • When the headlamp of an oncoming vehicle is detected.
  • When the tail lamp of a vehicle in front is detected.
  • When the headlamp or tail lamp of a motorcycle or a bicycle is detected.
  •  When the surrounding ambient light is bright enough that high beams are not required.
  • When streetlights or other lights are detected.
