AFS (Adaptive Front-lighting System) (if equipped)

AFS (Adaptive Front-lighting System) secures excellent visibility at intersections and on curves by automatically adjusting the direction of the light axis of the headlights according to vehicle speed and the degree of the tire's angle as controlled by steering input.

AFS operates at speeds of 6 mph (10 km/h) or higher.

Cornering lights (if equipped)

  • When the steering wheel or turn signal lever is operated while the headlights are on (low beam), a cornering light will turn on and light up the direction of movement of the vehicle. The cornering lights are designed to ensure excellent visibility when making a turn at an intersection.

    However, when vehicle speed is approximately 22 mph (35 km/h) or higher, the cornering lights will not turn on.

  • When the shift lever is in R while the headlights are on (low beam), both cornering lights will turn on. This is designed to enhance visibility when parking.

■ Daytime running light system

  • The daytime running lights illuminate using the same lights as the parking lights and illuminate brighter than the parking lights.
  • To make your vehicle more visible to other drivers during daytime driving, the daytime running lights turn on automatically when all of the following conditions are met. (The daytime running lights are not designed for use at night.)
    • The hybrid system is started
    • The parking brake is released
    • The headlight switch is in the (Canada only), or * position

    *: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the parking brake is set again.

  • For the U.S.A.: Daytime running lights can be turned off by operating the switch.
  • Compared to turning on the headlights, the daytime running light system offers greater durability and consumes less electricity, so it can help improve fuel economy.

■ Cornering lights (if equipped) When the cornering lights are on for more than 30 minutes, they will turn off automatically.

■ Headlight control sensor The sensor may not function properly if an object is placed on the sensor, or anything that blocks the sensor is affixed to the windshield.

Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight system to malfunction.

  • When the headlights come on: The headlights and tail lights turn off 30 seconds after a door is opened and closed if the power switch is turned to ACCESSORY mode or turned off. (The lights turn off immediately if on the key is pressed after all the doors are locked.)
  • When only the tail lights come on: The tail lights turn off automatically if the power switch is turned to ACCESSORY mode or turned off and the driver's door is opened.

    To turn the lights on again, turn the power switch to ON mode, or turn the light switch off once and then back to Lexus RX. Operating the lights and wipersor .

■ Light reminder buzzer A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode and the driver's door is opened while the lights are turned on.

■ Welcome lighting If the headlight switch is turned to Lexus RX. Operating the lights and wipers and the surrounding area is dark, unlocking the doors using the smart access system with push-button start or wireless remote control will turn the parking lights and tail lights on automatically.

■ Windshield wiper linked headlight illumination When driving during daytime with the headlight switch turned to Lexus RX. Operating the lights and wipers, if the windshield wipers are used, the headlights will turn on automatically after several seconds to help enhance the visibility of your vehicle.

■ 12-volt battery-saving function In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights and/or tail lights are on when the power switch is turned off the 12-volt battery saving function will operate and automatically turn off all the lights after approximately 20 minutes.

When the power switch is turned to ON mode, the 12-volt battery-saving function will be disabled.

When any of the following are performed, the 12-volt battery-saving function is canceled once and then reactivated. All the lights will turn off automatically 20 minutes after the 12-volt battery-saving function has been reactivated:

  • When the headlight switch is operated
  • When a door is opened or closed

■ Customization Some functions can be customized.


■ To prevent 12-volt battery discharge Do not leave the lights on longer than necessary when the hybrid system is off.
