Nissan ARIYA 2024 Owners Manual
9.20.3. Intelligent Forward Collision Warning system limitations
Listed below are the system limitations for the Intelligent Forward Collision Warning system. Failure to operate the vehicle in accordance with these system limitations could result in serious injury or death.
The Intelligent Forward Collision Warning system cannot detect all vehicles under all conditions.
The radar sensor does not detect the following objects:
Pedestrians, animals or obstacles in the roadway
Oncoming vehicles
Crossing vehicles
(Illustration A) The Intelligent Forward Collision Warning system does not function when a vehicle ahead is a narrow vehicle, such as a motorcycle.
The radar sensor may not detect a vehicle ahead in the following conditions:
Snow or heavy rain
Dirt, ice, snow or other material covering the radar sensor
Interference by other radar sources
Snow or road spray from travelling vehicles.
Driving in a tunnel
Towing a trailer
(Illustration B) When the vehicle ahead is being towed.
(Illustration C) When the distance to the vehicle ahead is too close, the beam of the radar sensor is obstructed.
(Illustration D) When driving on a steep downhill slope or roads with sharp curves.
The system is designed to automatically check the sensor’s functionality, within certain limitations. The system may not detect some forms of obstruction of the sensor area such as ice, snow, stickers, for example. In these cases, the system may not be able to warn the driver properly. Be sure that you check, clean and clear the sensor area regularly.
Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
When driving on some roads, such as winding, hilly, curved, narrow roads, or roads which are under construction, the radar sensor may detect vehicles in a different lane, or may temporarily not detect a vehicle travelling ahead. This may cause the Intelligent Forward Collision Warning system to work inappropriately.
The detection of vehicles may also be affected by vehicle operation (steering manoeuvre or travelling position in the lane, etc.) or vehicle condition. If this occurs, the system may warn you by blinking the vehicle ahead detection indicator and sounding the chime unexpectedly. You will have to manually control the proper distance away from the vehicle travelling ahead.
