WARNING
● The FCW system is intended to warn you before a collision but will not avoid a collision. It is the drivers 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 obstacles in the roadway
Oncoming vehicles in the same lane
● The system will not detect another vehicle under the following conditions:
When the sensor gets dirty and it is impossible to detect the distance from the vehicle ahead.
When driving into a strong light (for example, sunlight)
● The sensor generally detects the signals returned from the reflectors on a vehicle ahead. Therefore, the system may not function properly under the following conditions:
When the reflectors of the vehicle ahead are positioned high or close to each other (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 vehicles conditions (position in lane, etc.), the system may not function properly. The system may detect highly reflective objects such as reflectors, signs, white markers, 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 sensors functionality.

When the sensor detects an obstruction of the radar signals due to dirt, adhesive material, or similar objects to the front bumper, the system will automatically cancel. However, sensor may not detect all obstructive material. In these instances the system may not be able to warn the driver properly. Be sure to check and clean the sensor 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 and the IBA OFF indicator light will illuminate under the following conditions:
When the sensor area of the front bumper is dirty
When the system malfunctions

If the IBA OFF indicator light illuminates with a beep sound, pull off the road to a safe location, stop the vehicle and turn the engine off. illuminates 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 front bumper is dirty. If the sensor area of the front bumper is dirty, clean it with a soft cloth and restart the engine. If the sensor window is not dirty, restart the engine. If the IBA OFF indicator light continues to illuminate even if the IBA system is disabled, have the system checked by an INFINITI retailer. continues to illuminate even if the IBA system is disabled, have the system checked by an INFINITI retailer.
