How to disable Adaptive Front Lighting on your Lexus RX

Lexus’s Intelligent Adaptive Front Lighting System, as fitted to the Lexus RX 450h, is a driver-aid that adjusts the direction of the headlights in response to steering inputs and vehicle speed, in effect pointing the low-beam headlights into the corner and improving your view.

The system is enabled by default, but should you wish to temporarily disable it, watch the tutorial video below or read on for our step-by-step ‘how to’.

  1. On the steering wheel of the Lexus RX, press the ‘MENU’ button and use the arrow buttons to cycle through until ‘AFS’ lights up in the dash display.
  2. Press the ‘ENTER’ button on the steering wheel, which moves the dash display indicator to ‘AFS OFF’, disabling the system.
  3. Press the ‘MENU’ button once more to return to the main display.
  4. To re-enable the system, simply repeat the procedure to switch the display from ‘AFS OFF’ to ‘AFS ON’. The Intelligent Adaptive Front-Lighting System is operational once again.

  1. I’ll be travelling abroad next week in my 2013 RX450h Premier, do I need to disable the AFS? Do I need to apply adapter stickers to the lenses?

    1. Hi Mark,

      Thanks for getting in touch. No, it is illegal to do this as it can blind other drivers.
      The vehicle has a flat beam pattern and therefore is suitable for touring.

      Hope this helps.

      1. Hi, thanks for your reply. Apologies, not exactly sure what you mean by it’s illegal.
        Is it illegal to use the Adaptive lighting or is it illegal to disable it?

        1. AFS adapts the headlamp level to how the vehicle is sitting, this is designed so that the headlights do not point too high if there is a weight in the rear. It is a legal requirement for any vehicle with LED or HID lamps to have an adaptive system, so therefore you can’t disable it.

          Sorry for the confusion, hope this helps!

          1. Now I’m really confused. Your article is titled ‘How to disable Adaptive Front Lighting on your Lexus RX’ but yet you say it’s illegal to disable it. Why have the option if it’s illegal?
            All I want to know is Do I need to switch off the adaptive front lights when driving abroad?

          2. Apologies again for the confusion. An investigation will be going into this and we will get back to you as soon as possible.

            Thanks.
