Hyundai i-30: Limitations of the system / Detecting vehicles

The sensor may be limited when:

• The radar sensor or camera is blocked with a foreign object or debris
• Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
• There is interference by electromagnetic waves
• There is severe irregular reflection from the radar sensor
• The radar/camera sensor recognition is limited
• The vehicle in front is too small to be detected (for example a motorcycle or a bicycle, etc.)
• 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 driver'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 vehicle in front does not have their rear lights properly turned ON
• The outside brightness changes suddenly, for example when entering or exiting a tunnel
• When 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 windscreen glass is fogged up; a clear view of the road is obstructed
• The vehicle in front is driving erratically
• The vehicle is on unpaved or uneven rough surfaces, or road with sudden gradient changes.
• The vehicle is driven near areas containing metal substances as a construction zone, railroad, etc.
• The vehicle drives inside a building, such as a basement parking lot
• The adverse road conditions cause excessive vehicle vibrations whilst driving
• The sensor recognition changes suddenly when passing over a speed bump
• 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
• You are on roundabouts and the vehicle in front circles

- Driving on a curve

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

On curved roads, the other vehicle on the same lane is not recognized and the FCA system’s performance may be degraded. This may result in unnecessary alarm or braking or no alarm or braking when necessary.

Also, in certain instances the front radar sensor or camera recognition system may not detect the vehicle travelling 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 recognise 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, whilst 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 whilst 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 recognises the vehicle in front whilst passing over a slope, you may experience sharp deceleration.

Always keep your eyes forward whilst 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 stopped 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.
