Infiniti QX: Forward Collision Warning (FCW) system (if so equipped) - Starting and driving - Infiniti QX Owner's ManualInfiniti QX: Forward Collision Warning (FCW) system (if so equipped)

The Forward Collision Warning (FCW) system will warn the driver by a warning light and chime when your vehicle is getting close to the vehicle ahead in the traveling lane. The FCW system will function when your vehicle is driven at speeds of approximately 10 MPH (15 km/h) and above.

The FCW system uses the distance sensor

The FCW system uses the distance sensor A located below the front bumper to measure the distance to the vehicle ahead. When the system judges that your vehicle is getting close to the vehicle ahead in the travel lane, the vehicle ahead detection indicator blinks and a warning chime sounds.

Precautions on FCW system

► The FCW system is intended to warn you WARNING

► The FCW system is intended to warn you before a collision but will not avoid 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 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 gets dirty or it is impossible to detect the distance from the vehicle ahead. — When the reflectors on the vehicle ahead are missing, damaged or covered. — When the reflectors of the vehicle ahead are covered with dirt, snow or road spray. — When visibility is low (such as rain, fog, snow, etc.). — When snow or road spray from traveling vehicles is splashed. — When dense exhaust or other smoke (black smoke) from vehicles reduces the visibility of the sensor. — 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 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 sensor’s functionality. If the sensor is covered with ice, a transparent or translucent plastic 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 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 window is dirty
— When the system malfunctions

If the IBA OFF indicator lightA illuminates

If the IBA OFF indicator lightA 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 sensor window is dirty. If the sensor window 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 turned on with the IBA OFF switch B , have the system checked by an INFINITI retailer. To turn on the IBA system, see “Intelligent Cruise Control (ICC) system” later in this section.

FCW system operation

The warning systems switch is used to turn

The warning systems switch is used to turn on and off the FCW system when it is activated using the settings menu on the center display. See “How to enable/disable the FCW system using the settings menu” later in this section. When the warning systems switch is turned off, the indicator 1 on the switch is off. The indicator will also be off if the FCW, the Lane Departure Warning (LDW) and the Blind Spot Warning (BSW) systems are deactivated. For the LDW and BSW systems, see “Lane Departure Warning (LDW)/Prevention (LDP) system ” earlier in this section and “Blind Spot Warning (BSW) system/Blind Spot InterventionTM system” earlier in this section. For the sensor maintenance, see “Intelligent Cruise Control (ICC) system” earlier in this section.
