Hyundai Elantra: Forward Collision Avoidance (FCA) System / Limitations of the System

The Forward Collision Avoidance Assist (FCA) system is designed to monitor the vehicle ahead on the roadway through camera recognition to warn the driver that a collision is imminent, and if necessary, apply emergency braking.

In certain situations, the camera may not be able to detect the vehicle ahead. In these cases, the FCA system may not operate normally. The driver must pay careful attention in the following situations where the FCA operation may be limited.

Detecting vehicles

The sensor may be limited when:

• The camera is blocked with a foreign object or debris
• Inclement weather such as heavy rain or snow obscures the field of view of the camera
• There is interference by electromagnetic waves
• The vehicle is on unpaved or uneven rough surfaces, or road with sudden gradient changes.
• The vehicle drives through a construction area, on an unpaved road, or above metal materials, such as a railway
• The vehicle in front is too small to be detected (for example a motorcycle or a bicycle, etc.)
• The camera's field of view is not well illuminated (either too dark or too much reflection or too much backlight that obscures the field of view)
• The camera does not recognize the entire vehicle in front.
• The vehicle in front is an oversize vehicle or trailer that is too big to be detected by the camera recognition system (for example a tractor trailer, etc.)
• The vehicle in front does not have rear lights or the rear lights are not turned ON or the rear lights are located unusually.
• The outside brightness changes suddenly, for example when entering or exiting a tunnel
• The vehicle is moving underground level or inside a building
• The vehicle drives inside a building, such as a basement parking lot
• The adverse road conditions cause excessive vehicle vibrations while driving
• You are on a roundabout and the vehicle in front circles
• The camera lens is contaminated due to tinted, filmed or coated windshield, damaged glass, or stuck of foreign matter (sticker, bug, etc.) on the glass
• The camera is damaged.
• The brightness outside is too low such as when the headlamps are not on at night or the vehicle is going through a tunnel.
• Light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
• The field of view in front is obstructed by sun glare
• The shadow is on the road by a median strip, trees, etc.
• The vehicle drives through a tollgate.
• The windshield glass is fogged up; a clear view of the road is obstructed
• The camera sensor recognition is limited
• The rear part of the vehicle in front is not normally visible (for example, the vehicle is spinning or the vehicle is overturned)
• The sensor recognition changes suddenly when passing over a speed bump
• The vehicle in front is driving erratically
• The vehicle in front is moving vertically to the driving direction
• The vehicle in front is stopped vertically
• The vehicle in front is driving towards your vehicle or reversing

• Driving on a curve

The performance of the FCA system may be limited when driving on a curved road.

In certain instances on a curved road, the FCA system may activate prematurely.

Also, in certain instances the front camera recognition system may not detect the vehicle traveling on a curved road.

In these cases, the driver must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

The FCA system may recognize a vehicle in the next lane when driving on a curved road.

In this case, the system may unnecessarily alarm the driver and apply the brake.

Always pay attention to road and driving conditions, while driving. If necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

Also, when necessary depress the accelerator pedal to prevent the system from unnecessarily decelerating your vehicle.

• Driving on a slope

The performance of the FCA decreases while driving upward or downward on a slope, not recognizing the vehicle in front in the same lane. It may unnecessarily produce the warning message and the warning alarm, or it may not produce the warning message and the warning alarm at all.

When the FCA suddenly recognizes the vehicle in front while passing over a slope, you may experience sharp deceleration.

Always keep your eyes forward while driving upward or downward on a slope, and, if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

• Changing lanes

When a vehicle changes lanes in front of you, the FCA system may not immediately detect the vehicle, especially if the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

When driving in stop-and-go traffic, and a vehicle in front of you merges out of the lane, the FCA system may not immediately detect the new vehicle that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

• Detecting the vehicle in front of you

If the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance, additional special attention is required. The FCA system may not be able to detect the cargo extending from the vehicle. In these instances, you must maintain a safe braking distance from the rearmost object, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

Information

In some instances, the FCA system may be canceled when subjected to electromagnetic interference.

Information

This device complies with Part 15 of the FCC rules.

Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired operation.

WARNING

• Do not use the Forward Collision Avoidance Assist (FCA) system when towing a vehicle. Application of the FCA system while towing may adversely affect the safety of your vehicle or the towing vehicle.
• Use extreme caution when the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance.
• The FCA system is designed to detect and monitor the vehicle ahead in the roadway through camera recognition. It is not designed to detect pedestrians, bicycles, motorcycles, or smaller wheeled objects such as luggage bags, shopping carts, or strollers.
• Never try to test the operation of the FCA system. Doing so may cause severe injury or death.
