Nissan Altima (L34) 2019-2024 Owners Manual: I-LI system limitations

WARNING

Listed below are the system limitations for the I-LI system. Failure to follow the warnings and instructions for proper use of the I-LI system could result in serious injury or death.

• The I-LI system may activate if you change lanes without first activating your turn signal or, for example, if a construction zone directs traffic to cross an existing lane marker. If this occurs you may need to apply corrective steering to complete your lane change.
• Because the I-LI may not activate under the road, weather, and lane marker conditions described in this section, it may not activate every time your vehicle begins to leave its lane and you will need to apply corrective steering.
• When the I-LI system is operating, avoid excessive or sudden steering maneuvers. Otherwise, you could lose control of the vehicle.
• The I-LI system will not operate at speeds below approximately 37 mph (60 km/h) or if it cannot detect lane markers.
• Do not use the I-LI system under the following conditions as it may not function properly:
  • During bad weather (rain, fog, snow, etc.).
  • When driving on slippery roads, such as on ice or snow.
  • When driving on winding or uneven roads.
  • When there is a lane closure due to road repairs.
  • When driving in a makeshift or temporary lane.
  • When driving on roads where the lane width is too narrow.
  • When driving without normal tire conditions (for example, tire wear, low tire pressure, installation of spare tire, tire chains, non-standard wheels).
  • When the vehicle is equipped with non-original brake parts or suspension parts.
  • When you are towing a trailer or other vehicle.
  • On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt, snow, etc.
  • On roads where discontinued lane markers are still detectable.
  • On roads where there are sharp curves.
  • On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs.

    (The I-LI system could detect these items as lane markers.)

  • On roads where the traveling lane merges or separates.
  • When the vehicle’s traveling direction does not align with the lane marker.
  • When traveling close to the vehicle in front of you, which obstructs the lane camera unit detection range.
  • When rain, snow or dirt adheres to the windshield in front of the lane camera unit.
  • When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
  • When strong light enters the lane camera unit. (For example, the light directly shines on the front of the vehicle at sunrise or sunset.)
  • When a sudden change in brightness occurs. (For example, when the vehicle enters or exits a tunnel or under a bridge.)

While the I-LI system is operating, you may hear a sound of brake operation. This is normal and indicates that the I-LI system is operating properly.
