Basic information

WARNING

Failure to follow the warnings and instructions for proper use of the IBSI system could result in serious injury or death.

• The I-BSI system is not a replacement for proper driving procedures and is not designed to prevent contact with vehicles or objects. When changing lanes, always use the side and rear mirrors and turn and look in the direction your vehicle will move to ensure it is safe to change lanes.

  Never rely solely on the I-BSI system.

• There is a limitation to the detection capability of the radar. Not every moving object or vehicle will be detected. Using the I-BSI system under some road, ground, lane marker, traffic or weather conditions could lead to improper system operation. Always rely on your own operation to avoid accidents.

The I-BSI system helps alert the driver of other vehicles in adjacent lanes when changing lanes, and helps assist the driver to return the vehicle to the center WARNING of the traveling lane.

The I-BSI system uses radar sensors A installed near the rear bumper to detect other vehicles in an adjacent lane. In addition to the radar sensors, the I-BSI system uses a camera B installed behind the windshield to monitor the lane markers of your traveling lane.

Detection zone

The radar sensors can detect vehicles on either side of your vehicle within the detection zone shown as illustrated.

This detection zone starts from the outside mirror of your vehicle and extends approximately 10 ft (3.0 m) behind the rear bumper, and approximately 10 ft (3.0 m) sideways.

I-BSI system operation

Example

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

The I-BSI system operates above approximately 37 MPH (60 km/h).

If the radar sensors detect a vehicle in the detection zone, the side indicator light illuminates.

If the turn signal is then activated, the system chimes (twice) and the side indicator light and I-BSI indicator flash. The side indicator light and I-BSI indicator continue to flash until the detected vehicle leaves the detection zone.

If the I-BSI system is ON and your vehicle approaches a lane marker while another vehicle is in the detection zone, the system chimes (three times) and the side indicator light and I-BSI indicator flash.

The I-BSI system activates to help return the vehicle back to the center of the driving lane. The I-BSI system operates regardless of turn signal usage.

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

NOTE

• I-BSI warning and system application will only be activated if the side indicator light is already illuminated when your vehicle approaches a lane marker. If another vehicle comes into the detection zone after your vehicle has crossed a lane marker, no I-BSI warning or system application will be activated.
• The I-BSI system is typically activated earlier than the Intelligent Lane Intervention (I-LI) system when your vehicle is approaching a lane marker.

How to enable/disable the I-BSI system

Example

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

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 "Blind Spot 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-BSI and I-LI systems at the same time. For additional information, see "Intelligent Lane Intervention (I-LI)".
• The system will retain current settings in the vehicle information display even if the EV system is restarted.

I-BSI system limitations

WARNING

Listed below are the system limitations for the I-BSI system. Failure to operate the vehicle in accordance with these system limitations could result in serious injury or death.

• The I-BSI system cannot detect all vehicles under all conditions.
• The radar sensors may not be able to detect and activate I-BSI when certain objects are present such as:
  • Pedestrians, bicycles, animals.
  • Vehicles such as motorcycles, low height vehicles, or high ground clearance vehicles.
  • Vehicles remaining in the detection zone when you accelerate from a stop.
  • Oncoming vehicles.
  • A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle.
  • A vehicle approaching rapidly from behind.
  • A vehicle which your vehicle overtakes rapidly.
  • A vehicle that passes through the detection zone quickly.
• The radar sensor's detection zone is designed based on a standard lane width. When driving in a wider lane, the radar sensors may not detect vehicles in an adjacent lane. When driving in a narrow lane, the radar sensors may detect vehicles driving two lanes away.
• The radar sensors are designed to ignore most stationary objects, however objects such as guardrails, walls, foliage and parked vehicles may occasionally be detected. This is a normal operation condition.
• The following conditions may reduce the ability of the radar to detect other vehicles:
  • Severe weather
  • Road spray
  • Ice/frost/dirt build-up on the vehicle
• Do not attach stickers (including transparent material), install accessories or apply additional paint near the radar sensors.

  These conditions may reduce the ability of the radar to detect other vehicles.

• The camera may not detect lane markers in the following situations and the I-BSI system may not operate properly.
  • 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; 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.
  • On roads where the traveling lane merges or separates.
  • When the vehicle's traveling direction does not align with the lane markers.
  • 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 a lane camera unit.
  • When the headlights are not bright due to dirt on the lens or if aiming is not adjusted properly.
  • When strong light enters a lane camera unit. (For example: 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.)
• Do not use the I-BSI system under the following conditions because the system may not function properly.
  • During bad weather. (For example: rain, fog, snow, etc.)
  • When driving on slippery roads, such as on ice or snow, etc.
  • 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 with a tire that is not within 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 steering parts or suspension parts.
  • When towing a trailer or other vehicle (AWD models).
• Excessive noise (for example, audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard.

System maintenance

Basic information

The two radar sensors A for the I-BSI system are located near the rear bumper.

Always keep the area near the radar sensors clean.

The radar sensors may be blocked by temporary ambient conditions such as snow, splashing water, mist or fog.

The blocked condition may also be caused by objects such as ice, frost or dirt obstructing the radar sensors.

Check for and remove objects obstructing the area around the radar sensors.

Do not attach stickers (including transparent material), install accessories or apply additional paint near the radar sensors.

Do not strike or damage the area around the radar sensors.

It is recommended you visit a NISSAN certified ARIYA dealer if the area around the radar sensors is damaged due to a collision.

The lane camera unit B for I-BSI system is located above the inside mirror. To keep the proper operation of I-BSI 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. It is recommended you contact a NISSAN certified ARIYA dealer if the camera unit is damaged due to an accident.

Precautions on repairing the bumper

When repairing the bumper, take caution because the radar sensors are installed on the bumper.

The radar sensor detects objects by emitting a radar signal and then measuring its reflection.

WARNING

If an improper repair is performed on the bumper (for example, application of putty made from different materials, repaint, etc.) the radar signal could be weakened or prevented from functioning properly. This may cause the radar sensor not to detect objects correctly. Improper repair may result in serious personal injury.

If it is necessary to repair the bumper, it is recommended you visit a NISSAN certified ARIYA dealer for this service.
