Nissan Pathfinder: Starting and driving - 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 ignition is placed in the ON position.

The I-LI system will operate when the vehicle is driven at speeds of approximately 37 mph (60 km/h) and above, 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 a 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

For vehicles with the 7 inch (18 cm) display

1. Lane Departure Warning (LDW) indicator
2. Intelligent Lane Intervention (I-LI) indicator (if so equipped)
3. ProPILOT Assist switch

The I-LI system operates above approximately 37 mph (60 km/h). When the vehicle approaches either the left or the right side of the traveling lane, the steering wheel will vibrate and the LDW indicator (orange) on the instrument panel 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.

For vehicles with the 12.3 inch (31.2 cm) display

To turn on the I-LI system, push the ProPILOT Assist switch on the steering wheel after starting the engine/motor. The I-LI indicator on the instrument panel will illuminate.

Push the ProPILOT Assist switch again to turn off the I-LI system. The I-LI indicator will turn off.

The strength of the steering wheel vibration can be changed in the settings menu of the vehicle information display.

NOTE:

• Turning on the ProPILOT Assist system will turn on the I-LI and I-BSI (if so equipped) 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. For additional information, see "ProPILOT Assist".
• When enabling/disabling the system, the system will retain current setting even if the engine 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.
• 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.
  • hen 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.

System temporarily unavailable

Condition A:

The warning and assist functions of the I-LI 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).

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.
• When the steering wheel is turned as far as necessary for the vehicle to change lanes.
• When the vehicle is accelerated during 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.

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 messages appear in the vehicle information display, the I-LI system will be turned off automatically.

• "Not Available Poor Road Conditions"
  When the VDC system (except Traction Control System [TCS] function) or ABS operates.
• "Currently not available":
  • When the VDC system is turned off.
  • When the SNOW mode, or the MUD/ RUT mode or SAND mode (4WD models only) is selected.

Action to take:

hen the above conditions no longer exist, turn off the I-LI system. Push the ProPILOT Assist switch (for vehicles with ProPILOT Assist) on the steering wheel again to turn the I-LI 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, the following message will appear on the vehicle information display: "Unavailable: High Cabin Temperature" and a chime will sound.

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

System malfunction

If the I-LI system malfunctions, it will cancel automatically. The LDW indicator (orange) and the "Not Available System Malfunction" warning message will display and a chime will sound. If the LDW indicator (orange) and the warning message appear in the display, pull off the road to a safe location and stop the vehicle. Turn the engine/motor off and restart the engine/motor. If the LDW indicator (orange) and warning message continue to appear, have the I-LI system checked. It is recommended that you visit a NISSAN dealer for this service.

System maintenance

The lane camera unit 1 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 dealer.
