Nissan Ariya: Intelligent Lane Intervention (I-LI)

Basic information

WARNING

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 will not steer the vehicle or prevent loss of control.

  It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.

• The I-LI system is primarily intended for use on well-developed freeways or highways. It may not detect the lane markers in certain road, weather, or driving conditions.

The I-LI system must be turned on with the ProPILOT Assist switch on the steering wheel, every time the power switch is placed in the ON position.

The I-LI system will operate when the vehicle is driven at speeds of approximately 37 - 125 MPH (60 - 200 km/h), and only when the lane markings are clearly visible on the road. The I-LI system warns the driver when the vehicle has left the center of the traveling lane with an indicator and steering wheel vibration. The system helps assist the driver to return the vehicle to the center of the traveling lane by applying the brakes to the left or right wheels individually (for a short period of time).

The I-LI system monitors the lane markers on the traveling lane using the camera unit A located above the inside mirror.

I-LI system operation

Example

1. I-LI indicator (on the vehicle information display)
2. I-LI ON indicator (on the vehicle information display)
3. Vehicle information display
4. ProPILOT Assist switch (The design varies depending on the models.)

The I-LI system operates when the vehicle is driven at speeds of approximately 37 - 125 MPH (60 - 200 km/h) and when the lane markings are clear. When the vehicle approaches either the left or the right side of the traveling lane, steering wheel will vibrate and the I-LI indicator (orange) on the vehicle information display will blink to alert the driver. Then, the I-LI system will automatically apply the brakes for a short period of time to help assist the driver to return the vehicle to the center of the traveling lane.

To turn on the I-LI system, push the ProPILOT Assist switch on the steering wheel after starting the EV system. The I-LI ON indicator on the vehicle information display will illuminate. Push the ProPILOT Assist switch again to turn off the I-LI system.

The I-LI ON indicator will turn off.

How to enable/disable the I-LI system

Example

1. Steering-wheel-mounted control (left side)
2. Vehicle information display
3. ProPILOT Assist switch (The design varies depending on the models.)

Perform the following steps to enable or disable the I-LI system.

1. Push the button until "Settings" appears in the vehicle information display and then push the scroll dial.

Use the scroll dial to select "Driver Assistance." Then push the scroll dial.

2. Select "Lane Assist" and push the scroll dial.

3. Select "Intervention" and push the scroll dial.

4. Push the ProPILOT Assist switch to turn the system on or off.

NOTE

• Turning on the ProPILOT Assist system will turn on the I-LI and I-BSI systems at the same time. If the I-LI system is disabled in the settings menu, the I-LI will automatically be turned on when the Steering Assist system is active.
• The system will retain current settings in the vehicle information display even if the EV system is restarted.

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.
• The I-LI system will not operate at speeds below approximately 37 MPH (60 km/h) or if it cannot detect lane markers.
• When the I-LI system is operating, avoid excessive or sudden steering maneuvers. Otherwise, you could lose control of the vehicle.
• 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 tire chains or non-standard wheels).
  • When the vehicle is equipped with non-original brake parts or suspension parts.
  • When towing a trailer or other vehicle (AWD models).
  • 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.)
• Steering wheel vibration may not be felt depending on the road surface conditions.

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.

System temporarily unavailable

Condition A:

The warning and assist functions of the ILI system are not designed to work under the following conditions:

• When you operate the lane change signal and change the traveling lanes in the direction of the signal. (The I-LI system will be deactivated for approximately 2 seconds after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 MPH (60 km/h).

Action to take:

After the above conditions have finished and the necessary operating conditions are satisfied, the warning and assist functions will resume.

Condition B:

The assist function of the I-LI system is not designed to work under the following conditions (warning is still functional):

• When the brake pedal is depressed or if the vehicle decelerates strongly.
• When the steering wheel is turned as far as necessary for the vehicle to change lanes.
• When the vehicle is accelerated during the I-LI system operation.
• When the Intelligent Cruise Control (ICC) approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.

Action to take:

After the above conditions have finished and the necessary operating conditions are satisfied, the I-LI system application of the brakes will resume.

Condition C:

If the following message appears in the vehicle information display, a chime will sound and the I-LI system will be turned off automatically.

• "Unavailable Slippery Road":
  • When the Vehicle Dynamic Control (VDC) system (except Traction Control System (TCS) function) or ABS operates.
• "Currently Unavailable":
  • When the Vehicle Dynamic Control (VDC) system is turned off.
  • When the SNOW mode is selected (AWD models).

Action to take:

When the above conditions no longer exist, turn off the I-LI system. Push the ProPILOT Assist switch again to turn the ILI system back on.

Temporary disabled status at high temperature:

If the vehicle is parked in direct sunlight under high temperature conditions (over approximately 104ºF (40ºC) ) and then the I-LI system is turned on, the I-LI system may be deactivated automatically, a chime sounds and the following message will appear on the vehicle information display:

• "Unavailable Camera Temperature High"

When the interior temperature is reduced, turn off the I-LI system. Push the ProPILOT Assist switch again to turn the I-LI system back on.

System malfunction

If the I-LI system malfunctions, it will cancel automatically. The I-LI indicator (orange) will illuminate, a chime will sound and the "Malfunction See Owner's Manual" warning message will appear in the vehicle information display.

If the I-LI indicator (orange) illuminates, pull off the road to a safe location. Turn the EV system off and restart the EV system.

If the I-LI indicator (orange) continues to illuminate, have the I-LI system checked. It is recommended that you visit a NISSAN certified ARIYA dealer for this service.

System maintenance

The lane camera unit A for the I-LI system is located above the inside mirror. To keep the proper operation of the I-LI system and prevent a system malfunction, be sure to observe the following:

• Always keep the windshield clean.
• Do not attach a sticker (including transparent material) or install an accessory near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of sunlight may adversely affect the camera unit's capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera lens or remove the screw located on the camera unit. If the camera unit is damaged due to an accident, it is recommended that you visit a NISSAN certified ARIYA dealer.
