Nissan Rogue Owners Manual: Precautions on FCW system

Nissan Rogue Owners Manual / Starting and driving / Forward Collision Warning (FCW) system (if so equipped) / Precautions on FCW system

WARNING

The FCW system is intended to warn you before a collision occurs; it cannot prevent a collision. It is the driver’s responsibility to stay alert, drive safely and be in control of the vehicle at all times.
As there is a performance limit, the system may not provide a warning in certain conditions.
The system will not detect the following objects:

Pedestrians, animals or objects in the roadway
Oncoming vehicles in the same lane

The system will not detect another vehicle under the following conditions:

When the sensor area of the front bumper gets dirty and it is impossible to detect the distance from the vehicle ahead.
When the sensor signal is temporarily interrupted

The system may not function properly under the following conditions:

A preceding vehicle with a large amount of ground clearance
A protruding freight (including a small vehicle such as motorcycles)
When the sensor area of the front bumper gets dirty or it is impossible to detect the distance from the vehicle ahead.
When visibility is low (such as rain, fog, snow, etc.).
When snow or road spray from traveling vehicles is splashed.
When excessively heavy baggage is loaded in the rear seat or the luggage room of your vehicle.
When abruptly accelerating or decelerating.
On a steep downhill slope or on roads with sharp curves.
When there is a highly reflective object near the vehicle ahead (for example, being very close to another vehicle, signboard, etc.)
When you are towing a trailer.

Depending on certain road conditions (curved or beginning of a curve), vehicle conditions (steering position or vehicle position), or the preceding vehicle’s conditions (position in lane, etc.), the system may not function properly. The system may detect highly reflective objects such as guard rails, traffic signs and other stationary objects on the road or near the traveling lane and provide unnecessary warning.
The system may not function in offset conditions.
The system may not function when the distance to the vehicle ahead is extremely close.
The system is designed to automatically check the sensor’s functionality. If the sensor area of the front bumper is covered with ice, a transparent or translucent bag, etc., the system may not detect them. In these instances, the system may not be able to warn the driver properly. Be sure to check and clean the sensor area of the front bumper regularly.
Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
A sudden appearance of a vehicle in front (for example, it abruptly cuts in) may not be detected and the system may not warn the driver soon enough.
The system will be cancelled automatically with a beep sound, FCW light (orange) will illuminate and a message will pop up under the following conditions:

When the sensor area of the front bumper is dirty
When the system malfunctions

If the system cancels and a message appears with a beep sound, pull off the road to a safe location, stop the vehicle and turn the engine off.

Check to see if the sensor area of the front bumper is blocked. If the sensor area of the front bumper is blocked, remove the object blocking and restart the engine.

If the sensor is malfunctioning, have the system checked by a NISSAN dealer.
