ADAPTIVE HIGH BEAM SYSTEM

Text in Illustration
*a	Adaptive High Beam Indicator

When all of the following conditions are met, the adaptive high beam system enters standby and the adaptive high beam indicator in the combination meter assembly illuminates in green.

Turn the engine switch on (IG).
Turn the light control switch to the head or AUTO position.*1
Illuminate the low beam headlights.
Turn the dimmer switch to the high position.*2
The integration control and panel assembly (adaptive high beam switch) is on.

Note

If the forward recognition camera cannot correctly recognize the environment to the front of the vehicle due to poor weather conditions (heavy fog, etc.) or something covering the camera, the adaptive high beam indicator in the combination meter assembly may illuminate and the adaptive high beam system may not operate.
When the battery terminal is disconnected and the vehicle is not being driven, the adaptive high beam indicator may not illuminate and the adaptive high beam system may not operate. When disconnecting the battery terminal, perform a driving test in order to perform steering angle zero point calibration learning.
If the forward recognition camera is temporarily at high temperatures or automatically performing beam axis adjustment in response to changes to the vehicle posture due to the currently carried load, the adaptive high beam indicator may temporarily not illuminate and the adaptive high beam system may not operate.

Tech Tips

If the integration control and panel assembly (adaptive high beam switch) is turned on without performing *1 and *2 listed above, the "To Activate AHS, Switch Headlights to High Beam" message is displayed on the multi-information display in the combination meter assembly.

When all of the following conditions are met in adaptive high beam system standby mode, the low beam headlights change to high beam headlights automatically after a slight delay.

Vehicle speed is more than approximately 15 km/h (9 mph).
No oncoming vehicle with illuminated headlights or preceding vehicle with illuminated taillights
Few streetlights along road and surrounding environment is dark

High beam control switches to the following light distribution modes according to the vehicle speed.

Light Distribution Mode	Description	Vehicle Speed
Light Distribution Mode	Description	except Europe	for Europe
Residential Mode	The illumination ranges to the left and right sides are expanded in consideration of visibility at low speeds. It adjusts brightness to levels suitable for pedestrian visibility while reducing glare for pedestrians. Illumination of the sides of the roads and sidewalks is suppressed to reduce the amount of light that illuminates the surroundings.	15 to 30 km/h (9 to 25 mph)	-
Normal Mode	The necessary amount of light is spread to the left and right sides and long-range visibility is ensured.	30 to 80 km/h (25 to 50 mph)	60 to 120 km/h (37 to 75 mph)
High-speed Mode	High beams are illuminated to a narrow illumination range, achieving even further long-range visibility in consideration of visibility at high-speeds. Additional high beams are also illuminated to improve long-range visibility.	80 km/h or more (50 mph or more)	120 km/h or more (75 mph or more)

When all of the following conditions are met in adaptive high beam system standby mode, the system automatically switches to cut-off line tilt control (adjusts the low beam headlight illumination height).

Vehicle speed is more than approximately 15 km/h (9 mph).
Dark environment in front of vehicle
Oncoming vehicle with illuminated headlights or preceding vehicle with illuminated taillights

When all of the following conditions are met during headlight light distribution control, the system automatically changes to the shaded high beams after a slight delay.

Vehicle speed is more than approximately 15 km/h (9 mph).
Oncoming vehicle with illuminated headlights or preceding vehicle with illuminated taillights
Few streetlights along road and surrounding environment is dark

When all of the following conditions are met during headlight light distribution control, the system automatically changes to electronic swivel control.

Vehicle speed is more than approximately 30 km/h (25 mph).

When one of the following conditions is met during headlight light distribution control, the system automatically changes to the low beam headlights.

Vehicle speed is less than approximately 15 km/h (9 mph).
Oncoming vehicle with illuminated headlights or preceding vehicle with illuminated taillights
Bright environment in front of vehicle
A large number of vehicles are detected in front of the vehicle
A preceding vehicle moves quickly and this vehicle is struck by glare from the preceding vehicle

When one of the following conditions is met, the adaptive high beam system is canceled and the adaptive high beam indicator in the combination meter assembly turns off.

The engine switch is turned off.
The light control switch is turned to any position except the AUTO or head position.
The low beam headlights turn off.
The dimmer switch is moved to the low position.
The integration control and panel assembly (adaptive high beam switch) is off.

The adaptive high beam system may not operate normally due to the following factors.

Cause	Details
Weather/Climate	Bad weather (frost, snow, sandstorm, heavy rain, etc.) High cabin temperature (forward recognition camera is hot, etc.) Vehicle is driven on a snow-covered road and taillights of preceding vehicle are not visible due to kicked-up snow
Front windshield	Windshield is dirty (frozen water, snow, frost, etc.) Windshield is dirty (sand, dirt, lime deposits, insects, etc.) Windshield has cracks or damage Windshield is fogged up Windshield has film applied Windshield has different light transmission (not genuine part) Windshield shows reflections due to reflective objects on instrument panel Windshield is abnormal for other reasons
Forward recognition camera	Forward recognition camera is deformed or dirty Forward recognition camera is not installed correctly Forward recognition camera is abnormal for other reasons (high temperature, etc.)
Nearby vehicles or lights	Ambient light is similar to headlights or taillights Oncoming or preceding vehicle lights are not illuminated Oncoming or preceding vehicle lights are dirty or discolored Only one of oncoming or preceding vehicle lights is illuminated, or vehicle is a motorcycle Beam axis of oncoming vehicle lights is deviated A highly reflective object is in rear of preceding vehicle (shipping container, etc.) A light vehicle (bicycle, etc.) is detected Brightness continuously and suddenly changes
Road conditions	Repeated driving on a road with large differences in elevation Repeated driving on a road with many curves or driving on a road with sharp curves Driving on a rough road (gravel road, unpaved road, etc.) A sign, mirror or other highly reflective object is in front of the vehicle
Own vehicle	This vehicle has damaged or dirty headlights Vehicle is not level due to number of passengers, load weight, flat tire or towing
Adaptive high beam system	"Headlight System Malfunction Visit Your Dealer" is displayed in multi-information display Light distribution mode switching timing and shading areas feel abnormal or change repeatedly due to adaptive high beam system High beams may be a nuisance to surrounding vehicles and people (due to glare, etc.) for other reasons
