Basic information Nissan Pathfinder Fifth generation

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

• The I-BSI system is not a replacement for proper driving procedure 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 you 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 or the sonar.

  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 of the traveling lane.

The I-BSI system uses radar sensors 1 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 2 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.

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

1. Side indicator light
2. BSW indicator
3. Intelligent Blind Spot Intervention (I-BSI) indicator
4. ProPILOT Assist switch

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 (1) illuminates.

If the turn signal is then activated, the system chimes (twice) and the side indicator light and the BSW indicator light 2 flash.

The side indicator light continues to flash until the detected vehicle leaves the detection zone. The brightness of the side indicator light is adjusted automatically depending on the brightness of the ambient light.

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 the BSW indicator light 2 flash.

The I-BSI system activates by controlling the braking input of the vehicle for a short period of time to help return the vehicle back to the center of the driving lane. The I-BSI system operates regardless of turn signal usage.

For vehicles with the 12.3 inch (31.2 cm) display

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 prior to the Intelligent Lane Intervention (I-LI) system when your vehicle is approaching a lane marker.

To turn on the I-BSI system, push the ProPILOT Assist switch on the steering wheel after starting the engine. The I-BSI indicator will illuminate. Push the ProPILOT Assist switch again to turn off the I-BSI system.

The I-BSI indicator will turn off.

How to enable/disable the I-BSI system

I-BSI system limitations Nissan Pathfinder Fifth generation

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, or 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 sensors' 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.) 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.)

Basic information

The two radar sensors 1 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 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 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 certified NISSAN dealer if the area around the radar sensors is damaged due to a collision.

The lane camera unit 2 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 that you contact a certified NISSAN dealer if the camera unit is damaged due to an accident.
