System Limitations

FCA is a driver assistance system in certain hazardous driving conditions and does not take full responsibility for all risks associated with driving conditions.

FCA monitors road situations through the radar and camera sensor. Therefore, for situations outside the detection range, FCA usually cannot operate. The driver must exercise greater caution in the following situations. Operation of FCA may be limited.

Vehicle Recognition

The sensor may be limited when:

• The forward view camera or front radar sensor is blocked by a foreign object or debris.
• The camera lens is contaminated by window tint, film, or coating on the windshield, a damaged windshield, or a foreign object (sticker, bug, etc.) stuck to the glass.
• Bad weather, such as heavy rain or snow, blocks the field of view of the radar sensor or camera.
• Electromagnetic interference or waves are present.
• Strong irregular reflections are present at the radar sensor.
• Forward view camera / front radar sensor recognition is limited.
• The vehicle ahead is too small to be detected (for example, a motorcycle, etc.).
• The vehicle ahead is an oversized vehicle or trailer that is too large to be detected by the camera recognition system (e.g. a tractor-trailer, etc.).
• The camera's field of view is poorly lit (either too dark, or too much reflection or too much light that obscures the field of view).
• The vehicle ahead does not have its taillights, its taillights are not turned on, or its taillights are positioned unusually.
• External brightness changes suddenly, for example when entering or exiting a tunnel.
• When light comes from street lights or an oncoming vehicle is reflected on a wet road surface, such as a puddle on the road.
• The field of view ahead is blocked by sun glare.
• The vehicle ahead is driving erratically.
• The vehicle is on unpaved or uneven, rough surfaces, or on a road with sharp changes in gradient.
• The vehicle is driving near areas containing metallic objects, such as a construction zone or railway, etc.
• The vehicle enters a building, such as a multi-level underground parking garage.
• The forward view camera does not recognize the entire vehicle ahead.
• The forward view camera is damaged.
• The outside brightness is too low, for example, when the headlights are not on at night or the vehicle is passing through a tunnel.
• Shadows on the road from a median strip, trees, etc.
• The vehicle passes through a toll gate.
• The windshield is fogged; clear view of the road is obstructed.
• The rear of the vehicle ahead is usually not visible (the vehicle turns to the side or the vehicle overturns).
• Excessive vehicle vibration during driving due to adverse road conditions
• Sensor recognition changes suddenly when driving over a speed bump.
• The vehicle ahead moves laterally in the direction of travel.
• The vehicle ahead stops laterally.
• The vehicle ahead moves toward your vehicle or in reverse.
• You are on a roundabout and the vehicle is in the front circles.
• It is difficult to secure the field of view of the forward view camera, such as with glare, reflected light, and darkness.
• When the forward view camera is blocked by continuous washer spray and wiper operation.
• The vehicle ahead is a special target vehicle, trailer, or truck loaded with cargo of unusual shape.
• Ambient lighting is too bright or too dim.
• The forward view camera is contaminated by windshield tint, film attachment, water-repellent coating, damage, or foreign material such as a sticker or insect.
• When the forward view camera (including the lens) or front radar is damaged.
• When headlights are not used or a weak light is used at night or in a tunnel.
• Light shines in the driving direction of the vehicle (including headlights of an oncoming vehicle).
• When the rear of the vehicle ahead is small or low.
• When a trailer or other vehicle is towing the vehicle ahead.
• When the ground clearance of the front of the vehicle is high.
• When the vehicle ahead suddenly changes lanes unexpectedly.

- Driving on curves

The Forward Collision-Avoidance Assist system may be limited when driving on a curved road.

The forward view camera or front radar sensor recognition system may not detect a vehicle, pedestrian, or cyclist ahead on a curved road.

This may result in no warning and no braking when necessary.

Always pay attention to the road and driving conditions and, if necessary, press the brake pedal to reduce the driving speed to maintain a safe distance.

Forward Collision-Avoidance Assist may recognize a vehicle, pedestrian, or cyclist in an adjacent lane or outside the lane when driving on a curved road.

In this case, the system may warn the driver and apply the brakes unnecessarily. Always pay attention to road and traffic conditions while driving.

- Driving on slopes

The Forward Collision-Avoidance Assist system may be limited when driving uphill or downhill. The forward view camera or front radar sensor recognition may not detect a vehicle, pedestrian, or cyclist ahead.

This may result in unnecessary warning and braking, or no warning and braking when necessary.

When the system suddenly recognizes a vehicle, pedestrian, or cyclist ahead while driving through a slope, you may experience sudden deceleration.

Always look ahead while driving uphill or downhill and, if necessary, press the brake pedal to reduce driving speed to keep a safe distance.

- Lane change

When a vehicle changes lanes in front of you, Forward Collision-Avoidance Assist may not immediately detect the vehicle, especially if the vehicle changes lanes abruptly. In this case, maintain a safe braking distance and, if necessary, press the brake pedal to reduce the driving speed to keep a safe distance.

When driving in stop-and-go conditions and a vehicle stopped ahead of you leaves the lane, the Forward Collision-Avoidance Assist system may not immediately detect the new vehicle now in front of you. In this case, maintain a safe braking distance and, if necessary, press the brake pedal to reduce the driving speed to keep a safe distance.

- Vehicle Recognition

When the vehicle ahead has a heavy load loaded toward the rear, or when the vehicle ahead has low ground clearance, this may result in a dangerous situation. Always pay attention to road and traffic conditions while driving and, if necessary, depress the brake pedal to reduce speed and maintain a safe distance.
