Hyundai Santa Fe: Forward Collision–Avoidance Assist (FCA) (Sensor fusion) / System malfunction and limitations
System malfunction
When Forward Collision-Avoidance Assist is not working properly, the ‘Check Forward
Safety system(s)’ warning message will appear, and the
and
warning lights
will illuminate on the cluster. We recommend that the system be inspected by an
authorized HYUNDAI dealer.
System disabled
When the front windshield where the front view camera is located, front radar
cover or sensor is covered with foreign material, such as snow or rain, it can reduce
the detecting performance and temporarily limit or disable Forward Collision-Avoidance
Assist.
If this occurs the ‘Forward Safety system(s) disabled. Camera obscured’ or the
‘Forward Safety system(s) disabled. Radar blocked’ warning message, and the
and
warning lights
will illuminate on the cluster.
The system will operate normally when when such snow, rain or foreign material
is removed.
If the system does not operate normally after obstruction (snow, rain, or foreign
material) is removed, we recommend that the system be inspected by an authorized
HYUNDAI dealer.
WARNING
- Even though the warning message or warning light does not appear on
the cluster, Forward Collision-Avoidance Assist may not properly operate.
- Forward Collision-Avoidance Assist may not properly operate in an area
(e.g. open terrain), where any substance are not detected after turning ON the
engine.

- The vehicle in front has an unusual shape
- The vehicle in front is driving uphill or downhill
- The pedestrian or cyclist is not fully detected, for example, if the pedestrian
is leaning over or is not fully walking upright
- The pedestrian or cyclist is wearing clothing or equipment that makes
it difficult to detect as a pedestrian or cyclist
The illustration above shows the image the front view camera is capable of detecting
as a vehicle, pedestrian and cyclist.
- The pedestrian or cyclist in front is moving very quickly
- The pedestrian or cyclist in front is short or is posing a low posture
- The pedestrian or cyclist in front has impaired mobility
- The pedestrian or cyclist in front is moving intersected with the driving
direction
- There is a group of pedestrians, cyclists or a large crowd in front
- The pedestrian or cyclist is wearing clothing that easily blends into
the background, making it difficult to detect
- The pedestrian or cyclist is difficult to distinguish from the similar
shaped structure in the surroundings
- You are driving by a pedestrian, cyclist, traffic sign, structure, etc.
near the intersection
- Driving in a parking lot
- Driving through a tollgate, construction area, unpaved road, partial paved
road, uneven road, speed bumps, etc.
- Driving on an incline road, curved road, etc.
- Driving through a roadside with trees or streetlights
- The adverse road conditions cause excessive vehicle vibrations while driving
- Your vehicle height is low or high due to heavy loads, abnormal tire pressure,
etc.
- Driving through a narrow road where trees or grass are overgrown
- There is interference by electromagnetic waves, such as driving in an
area with strong radio waves or electrical noise
WARNING
• Driving on a curve
Forward Collision-Avoidance Assist may not detect other vehicles, pedestrians
or cyclists in front of you on curved roads adversely affecting the performance
of the sensors. This may result in no warning or braking assist when necessary.
When driving on a curve, you must maintain a safe braking distance, and if necessary,
steer the vehicle and depress the brake pedal to reduce your driving speed in order
to maintain a safe distance.
Forward Collision-Avoidance Assist may detect a vehicle, pedestrian or cyclist
in the next lane or outside the lane when driving on a curved road.
If this occurs, the system may unnecessarily warn the driver and control the
brake. Always check the traffic conditions around the vehicle.
• Driving on a slope
Forward Collision-Avoidance Assist may not detect other vehicles, pedestrians
or cyclists in front of you while driving uphill or downhill adversely affecting
the performance of the sensors.
This may result in unnecessary warning or braking assist, or no warning or braking
assist when necessary.
Also, vehicle speed may rapidly decrease when a vehicle, pedestrian or cyclist
ahead is suddenly detected.
Always have your eyes on the road while driving uphill or downhill and if necessary,
steer your vehicle and depress the brake pedal to reduce your driving speed in order
to maintain a safe distance.
• Changing lanes
[A] : Your vehicle, [B] : Lane changing vehicle
When a vehicle moves into your lane from an adjacent lane, it cannot be detected
by the sensor until it is in the sensor's detection range. Forward Collision-Avoidance
Assist may not immediately detect the vehicle when the vehicle changes lanes abruptly.
In this case, you must maintain a safe braking distance, and if necessary, steer
your vehicle and depress the brake pedal to reduce your driving speed in order to
maintain a safe distance.
[A] : Your vehicle, [B] : Lane changing vehicle, [C] : Same lane vehicle
When a vehicle in front of you merges out of the lane, Forward Collision-Avoidance
Assist may not immediately detect the vehicle that is now in front of you. In this
case, you must maintain a safe braking distance, and if necessary, steer your vehicle
and depress the brake pedal to reduce your driving speed in order to maintain a
safe distance.
• Detecting vehicle
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. Forward Collision- Avoidance Assist 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, steer your vehicle
and depress the brake pedal to reduce your driving speed in order to maintain distance.
WARNING
- When you are towing a trailer or another vehicle, we recommend that
Forward Collision-Avoidance Assist is turned off due to safety reasons.
- Forward Collision-Avoidance Assist may operate if objects that are
similar in shape or characteristics to vehicles, pedestrians and cyclists are
detected.
- Forward Collision-Avoidance Assist does not operate on bicycles, motorcycles,
or smaller wheeled objects, such as luggage bags, shopping carts, or strollers.
- Forward Collision-Avoidance Assist may not operate normally if interfered
by strong electromagnetic waves.
- Forward Collision-Avoidance Assist may not operate for 15 seconds after
the vehicle is started, or the front view camera is initialized.

Basic function
System warning and control
The basic function for Forward Collision- Avoidance Assist is to help warn and
control the vehicle depending on the collision level: ‘Collision Warning’, ‘Emergency
Braking’ and ‘Stopping vehicle and ending brake control’...
Lane Keeping Assist is designed to help detect lane markings (or road edges)
while driving over a certain speed. The system will warn the driver if the vehicle
leaves the lane without using the turn signal, or will automatically assist the
driver’s steering to help prevent the vehicle from departing the lane...
