WARNING

The following limitations apply to the Nissan Armada I-FCW system. Ignoring these limitations may result in serious injury or fatal accidents.

The Nissan Armada I-FCW system cannot detect every object or vehicle under all driving conditions.
The radar sensor does not detect:
- Pedestrians, animals, or stationary obstacles
- Oncoming vehicles
- Vehicles crossing from the side
(Illustration A) The system may not recognize narrow vehicles such as motorcycles.
The radar sensor may fail to detect vehicles ahead in conditions such as:
- Heavy rain or snowfall
- Obstruction by dirt, ice, or snow on the sensor
- Interference from external radar sources
- Road spray from surrounding traffic
- Driving through tunnels
- When towing a trailer
(Illustration B) When the vehicle ahead is being towed.
(Illustration C) When following distance is extremely short and radar detection is obstructed.
(Illustration D) When driving on steep descents or sharply curved roads.
The Nissan Armada system performs automatic sensor checks but may not detect all obstructions such as ice, stickers, or debris.

Regular inspection and cleaning of the sensor area are essential to maintain optimal performance.
Excessive cabin or environmental noise may prevent the driver from hearing warning chimes clearly.

Nissan Armada I-FCW sensor behavior on curved or complex roads

When driving the Nissan Armada on complex road types such as winding, hilly, narrow, or under-construction roads, the radar sensor may mistakenly detect vehicles in adjacent lanes or temporarily lose detection of the vehicle ahead. This may lead to inconsistent system behavior.

Vehicle handling characteristics, including steering inputs or lane positioning, as well as external factors, may influence detection accuracy. In such cases, the Nissan Armada I-FCW system may issue unexpected alerts, including flashing indicators and audible warnings.

The driver must remain attentive and manually maintain a safe following distance, as the Nissan Armada system is intended only as a support feature and not a substitute for safe driving practices.

I-FCW system operation

The Nissan Armada I-FCW system becomes active at speeds above approximately 3 MPH (5 km/h), ensuring functionality during most driving scenarios. When a potential forward collision risk is dete ...

System temporarily unavailable
