WARNING

The following points outline the critical operational boundaries and inherent limitations of the Intelligent Lane Intervention (I-LI) system. Failure to adhere strictly to these warnings and instructions regarding the proper and safe use of the I-LI system could lead to an unpredictable vehicle response, resulting in serious personal injury or fatal consequences.

• The I-LI system may trigger an intervention if you attempt to change lanes without first manually activating your turn signal. Furthermore, in complex scenarios such as construction zones where temporary markings direct traffic to cross over permanent or existing lane markers, the system might intervene unexpectedly. If such an event occurs, you must remain prepared to apply firm, corrective steering inputs immediately to safely complete your intended maneuver.
• Because the sophisticated I-LI software may not engage under various challenging road, adverse weather, or ambiguous lane marker conditions detailed in this manual, you cannot rely on it to activate every time your Nissan Leaf begins to drift out of its designated lane. You must always be ready to apply corrective steering to maintain your path.
• While the I-LI system is actively monitoring and assisting, you should strictly avoid making excessive, erratic, or sudden, violent steering maneuvers. Abrupt inputs while the system is applying corrective braking forces could potentially compromise vehicle stability and cause you to lose control of your Nissan Leaf.
• The I-LI system is designed for highway-speed driving and will not initiate operation at vehicle speeds falling below approximately 37 mph (60 km/h), nor will it function if the optical sensor array is unable to identify and lock onto clear lane markers.
• Do not attempt to utilize the I-LI system under the following environmental or mechanical conditions, as the system's ability to interpret road data may be severely compromised, leading to degraded performance or complete failure:
  • During severe weather events that obscure the camera's field of view, including heavy rain, thick fog, or blizzard-like snow conditions.
  • When driving on surfaces with significantly reduced traction, such as roads covered in black ice, packed snow, or loose gravel.
  • When navigating sharply winding mountain passes or highly uneven, pothole-ridden road surfaces.
  • When traveling through zones where road repairs or lane closures result in confusing, non-standard traffic patterns.
  • When driving within makeshift, narrow, or temporary lanes marked by cones or altered asphalt.
  • When driving on roads where the physical lane width is too narrow for the system to safely operate within its calibrated parameters.
  • When the vehicle is operating outside of factory-specified tire conditions, including scenarios involving severe tire wear, critically low tire pressure, the installation of a compact spare tire, the use of bulky tire chains, or the fitting of non-standard aftermarket wheels.
  • When the Nissan Leaf is modified with non-original, aftermarket brake components or non-certified suspension parts that alter the vehicle's braking characteristics.
  • On roadway sections that feature multiple parallel lane markers, markers that have faded to near invisibility, non-standard yellow paint, or when road markings are completely obscured by standing water, deep mud, or heavy snow accumulation.
  • On road segments where older, discontinued lane markers are still detectable by the camera, which can cause the system to misinterpret the intended path.
  • On road sections characterized by extremely sharp or tight-radius curves.
  • On roads where there are high-contrast visual objects such as deep tree shadows, melting snow patches, standing water reflections, deep wheel ruts, asphalt seams, or dark, heavy lines remaining from previous structural road repairs.

    (The I-LI system may mistakenly identify these visual anomalies as actual lane markers, triggering an unnecessary intervention.)

  • On road sections where the traveling lane merges rapidly or splits into multiple directions.
  • When the vehicle’s current heading angle does not align linearly with the projected trajectory of the painted lane markers.
  • When following another vehicle too closely, which obstructs the forward-facing camera unit's clear detection range.
  • When environmental debris such as heavy rain streaks, caked-on snow, or road grime accumulates on the windshield directly in front of the optical camera lens.
  • When headlight performance is diminished due to dirty lenses or if the headlight beam aim is not calibrated to proper factory specifications.
  • When intense, blinding light sources enter the lane camera’s aperture, such as direct, low-angle sunlight hitting the front of the vehicle during dawn or dusk.
  • When the vehicle experiences a sudden, drastic shift in ambient light intensity, such as the moment the vehicle enters or exits a dark tunnel or passes beneath a bridge.

While the I-LI system is actively engaged, you may hear the distinct mechanical sound of the braking system operating. This is a normal, intended sound confirming that the I-LI system in your Nissan Leaf is functioning properly and responding to detected lane drift.
