Nissan ARIYA 2023 Owners Manual
6.11.1.4. High beam assist (where fitted)
The high beam assist system will operate when the vehicle is driven at speeds of approximately 40 km/h (25 MPH) and above. If an oncoming vehicle or leading vehicle appears in front of your vehicle when the headlight high beam is on, the headlight will be switched to the low beam automatically.
Precautions on high beam assist
The high beam assist system is a convenience but it is not a substitute for safe driving operation. The driver should remain alert at all times, ensure safe driving practices and switch the high beams and low beam manually when necessary.
The high beam or low beam may not switch automatically under the following conditions. Switch the high beam and low beam manually.
During bad weather (rain, fog, snow, wind, etc.).
When a light source similar to a headlight or tail light is in the vicinity of the vehicle.
When the headlights of the oncoming vehicle or the leading vehicle are turned off, when the colour of the light is affected due to foreign materials on the lights, or when the light beam is out of position.
When there is a sudden, continuous change in brightness.
When driving on a road that passes over rolling hills, or a road that has level differences.
When driving on a road with many curves.
When a sign or mirror-like surface is reflecting intense light towards the front of the vehicle.
When the container, etc. being towed by a leading vehicle is reflecting intense light.
When a headlight on your vehicle is damaged or dirty.
When the vehicle is leaning at an angle due to a punctured tyre, being towed, etc.
The timing of switching the low beam and high beam may change under the following situations.
The brightness of the headlights of the oncoming vehicle or leading vehicle.
The movement and direction of the oncoming vehicle and the leading vehicle.
When only one light on the oncoming vehicle or the leading vehicle is illuminated.

High beam assist operations
To activate the high beam assist system, push the switch as illustrated with the AUTO position. The high beam assist indicator light in the meter will illuminate while the headlights are turned on.
If the high beam assist indicator light does not illuminate in the above condition, it may indicate that the system is not functioning properly. It is recommended you have the system checked by a NISSAN certified electric vehicle dealer.
When the vehicle speed lowers to less than approximately 20 km/h (13 MPH), the headlight remains the low beam.
To turn off the high beam assist system, push the switch again.
Ambient image sensor maintenance
The ambient image sensor (A) for the high beam assist system is located in front of the inside mirror. To keep the proper operation of the high beam assist system and prevent a system malfunction, be sure to observe the following:
Always keep the windscreen clean.
Do not attach a sticker (including transparent material) or install an accessory near the ambient image sensor.
Do not strike or damage the areas around the ambient image sensor. Do not touch the sensor lens that is located on the ambient image sensor.
If the ambient image sensor is damaged due to an accident, it is recommended you contact a NISSAN certified electric vehicle dealer.
