        Tech Tips


        • The detection distance varies depending on detected objects.

        • The timing of turning on and off the high beams varies depending on the intensity of oncoming (and preceding) vehicle lights.

      2. When passing a preceding vehicle:


        • When approaching a preceding vehicle, the automatic high beam system turns off the high beams approximately 600 m (1950 ft.) before reaching it.

        • When a preceding vehicle passes out of camera sensor range, the automatic high beam system turns the high beams on after a short delay.

        Tech Tips

        The timing of turning on and off the high beams varies depending on the intensity of the preceding vehicle lights.

    2. Adaptive High-beam System (AHS)


      1. An Adaptive High-beam System (AHS), which detects preceding and oncoming vehicles and automatically switches between the hi beam, lo beam and variable shade beam headlights, has been provided depending on the model.

      2. When the lo beam illumination conditions are met while the Adaptive High-beam System (AHS) is operating, the system changes light distribution for the lo beam headlights.

      3. When the hi beam illumination conditions are met while the Adaptive High-beam System (AHS) is operating, the system illuminates the hi beam headlights in a light distribution mode appropriate for the vehicle speed.

      4. The light distribution of the hi beam headlights has 3 different modes:


        1. Town Mode


          • This extends illumination to the sides at low-speeds.

        2. Normal Mode


          • This ensures brightness in front of the vehicle while extending illumination to the left and right sides at medium-speeds.

        3. High-speed Mode


          • This provides superior visibility in front of the vehicle at high-speeds.

      5. When the variable shade beam illumination conditions are met while the Adaptive High-beam System (AHS) is operating, the system illuminates, turns off or adjusts the light of the numerous LEDs arranged in the hi beam headlights to prevent glare from striking preceding and oncoming vehicles while illuminating other areas.

      6. When the hi beam headlights are illuminated, the system estimates the corner angle in the direction of travel according to the steering wheel operation angle, etc., and operates electronic swivel control to illuminate in the direction of travel.

      7. Light Distribution Control Function


        1. The light distribution of the hi beam headlights can create a condition where the brightness and illumination range are optimized according to the vehicle speed.

          Light Distribution Mode Control Description Vehicle Speed

          Town Mode (Except Models for Europe)

          B002B1B           		The illumination ranges to the left and right sides are expanded in consideration of visibility at low speeds. Furthermore, a brightness suitable for pedestrian visibility is achieved while glare is reduced for pedestrians. Also, illumination to the sides is reduced to suppress illumination which reaches the sides of the road and sidewalks. 15 km/h to 30 km/h (9 mph to 19 mph)

          Normal Mode

          B002AZ3           		The necessary amount of light is spread to the left and right sides and light is distributed towards the center area for long-range visibility.

          30 km/h to 80 km/h (19 mph to 50 mph)*1

          60 km/h to 120 km/h (37 mph to 74 mph)*2

          High-speed Mode

          B002AZY           		Light distribution is performed to narrow the illumination range, achieving even further long-range visibility in consideration of visibility at high-speeds. Also, outermost hi beams are illuminated.

          80 km/h (50 mph) or more*1

          120 km/h (74 mph) or more*2

      10. Lo Beam Headlight Cut Line Tilt Control Function


        1. The headlight leveling motor built into the headlight assembly is operated according to the position of the preceding vehicle detected by the forward recognition camera. As a result, the illumination area of the lo beam headlights is optimally controlled to illuminate the longest range possible while reducing glare.

      11. Adaptive High-beam System (AHS) Manual Switching Operation


        1. The headlights can be manually switched between the lo and hi beams while the headlights are controlled by the Adaptive High-beam System (AHS) by performing the following operation.


          • When switching from the hi beams or variable shade beam illumination to the lo beams, change the dimmer switch of the light control switch to the lo beam position. This operation cancels the Adaptive High-beam System (AHS) and illuminates the lo beams.*1

          • When switching from the lo beams to the hi beams, turn the AHS switch off. This operation turns the Adaptive High-beam System (AHS) off and illuminates the hi beams.*2

            Tech Tips

            *1: When using the Adaptive High-beam System (AHS) again, operate the dimmer switch to the hi beam position.

            *2: When using the Adaptive High-beam System (AHS) again, turn the AHS switch on.

      12. Combination Meter Assembly


        1. When the Adaptive High-beam System (AHS) is activated, the combination meter assembly informs the driver by illuminating the adaptive high-beam indicator light.

        2. When the hi beam headlights are on, the combination meter assembly informs the driver by illuminating the hi beam headlight indicator light.

        3. If malfunctions occur in the AHS, the combination meter assembly warns the driver by indicating a message on the multi-information display, sounding the buzzer and illuminates the master warning light when receiving signals from the headlight light control ECU assembly LH.

  5. CONSTRUCTION


    1. Projector Type Headlight Assembly


      1. Bi-function


        • If the low beam is selected, the lower illumination area of the LED is blocked by a shade and only the upper illumination area is used.

        • If the high beam is selected, the headlight solenoid rotates the shade down to allow use of the lower illumination area, thus increasing the illumination area and improving visibility when the high beam is selected.

        • The bi-function is activated by the headlight light control ECU assembly LH/RH. The headlight light control ECU assembly activates the built-in headlight solenoid to slide the shade down.

    3. Headlight Light Control ECU assembly and LED Light Control ECU


      1. The headlight light control ECU assembly LH/RH illuminates the LED used as a light source for the low beam headlights and high beam headlights.

      2. When the low beam headlights or high beam headlights are illuminated, a constant current flows to the LED to instantly stabilize the headlights.

      3. Also, changes in the LED current due to fluctuations in the voltage are reduced to prevent the lights from flickering.

      4. The LED light control ECU illuminates the LED used as a high beam source for the Adaptive High beam System (AHS).

      5. Also, changes in the each LED current for control the axes of the hi-beam headlight.
