Auto High-Beam
The front sensor camera detects the light sources ahead of the vehicle such as the
lights of a preceding or oncoming vehicle, or street lights. When you are driving at
night, the system automatically switches the headlights between low beam and high
beam depending on the situation.
When all of the following conditions have been met, the auto high-beam indicator
comes on and the auto high-beam is activated. •The power mode is in ON.
• The light switch is in AUTO.
• The lever is in the low beam position.
• The headlights have been automatically

In the following cases, th e auto high-beam system
may not switch the head lights properly or the
switching timing may be ch anged. In case of the
automatic switching operation does not fit for your
driving habits, please swit ch the headlights manually.
•The brightness of the lights from the preceding or
oncoming vehicle is intense or poor.
•Visibility is poor due to the weather (rain, snow,
fog, windshield frost, etc.).
•Surrounding light sources, such as street lights,
electric billboards and traf fic lights are illuminating
the road ahead.
•The brightness level of th e road ahead constantly
changes.
•The road is bumpy or has many curves.•A vehicle suddenly appears in front of you, or a
vehicle in front of you is not in the preceding or
oncoming direction.
•Your vehicle is tilted with a heavy load in the rear.•A traffic sign, mirror, or other reflective object
ahead is reflecting strong light toward the vehicle.
•The oncoming vehicle freq uently disappears under
roadside trees or be hind median barriers.
•The preceding or oncoming vehicle is a motorcycle,
bicycle, mobility scooter, or other small vehicle.
The auto high-beam system keeps the headlight low
