Basic function
The Forward Collision-Avoidance Assist (FCA) system in your Kia Carnival utilizes advanced sensor fusion technology
to monitor the road ahead. It is designed to detect vehicles, powered two-wheelers, pedestrians, and cyclists. If the
system calculates that a collision risk is imminent, it provides visual warnings on the instrument cluster and
audible alerts. To further protect you, the Kia Carnival may automatically apply emergency braking to reduce impact
speed or attempt to avoid the collision entirely.
Even at higher speeds, the FCA can monitor vehicles in adjacent lanes. If you initiate a lane change while a
potential hazard is detected, the Kia Carnival may trigger emergency braking to mitigate or prevent a side-swipe or
rear-end collision (if equipped).
Junction Turning function
When you are preparing to turn left at a crossroad with your turn signal active, the Junction Turning function
monitors the oncoming lane. If it detects an oncoming vehicle, motorcycle, or cyclist that poses a collision risk,
the system can assist by applying emergency braking to ensure a safer turn.
Junction Crossing function (if equipped)
The Junction Crossing function provides an additional layer of security when driving through an intersection. It can
detect vehicles approaching from the left or right and, if a collision risk is identified, the system will apply
emergency braking to help mitigate or avoid the impact.
Direct Oncoming Vehicle function

[A]: Oncoming vehicle
This function enhances safety by detecting vehicles or powered two-wheelers approaching from the opposite direction.
If the Kia Carnival detects a collision risk with an oncoming object, it can reduce the vehicle's speed to minimize
the severity of a potential frontal collision.
Lane-Change Oncoming function (if equipped)
![Kia Carnival Lane-Change Oncoming function detecting hazards during lane changes [A]: Oncoming vehicle](images/forward_collision_avoidance_assist_fca_sensor_fusion-617/1/kia-carnival-forward-collision-avoidance-assist-fca-sensor-fusion-5.webp)
[A]: Oncoming vehicle
When changing lanes, this feature helps mitigate or prevent collisions with oncoming traffic. If the system detects
an oncoming vehicle or motorcycle that you may have missed, it assists the driver's steering to help you safely
maintain your path.
Lane-Change Side function (if equipped)
![Kia Carnival Lane-Change Side function detecting a car approaching from the side [A]: Approaching car from side](images/forward_collision_avoidance_assist_fca_sensor_fusion-617/1/kia-carnival-forward-collision-avoidance-assist-fca-sensor-fusion-7.webp)
[A]: Approaching car from side
The Lane-Change Side function monitors the adjacent lane during a lane change maneuver. By assisting the driver's
steering, it helps prevent collisions with vehicles or powered two-wheelers that might be in your blind spot or
approaching rapidly from the side.
Evasive Steering Assist function (if equipped)
-
Driver steering assist: If the Kia Carnival detects a potential collision with a vehicle,
pedestrian, or cyclist ahead and you initiate a steering maneuver to avoid it, this system provides steering
torque assistance to ensure the evasive maneuver is more effective.
-
Evasive steering assist: This function is designed for scenarios where braking alone may not
be sufficient. If a collision risk is detected in your lane, the Kia Carnival warns you and provides steering
assistance if you move the steering wheel to swerve away. This function requires sufficient operating space
between your Kia Carnival and the detected pedestrian or cyclist to be effective.

Detecting sensor
The Forward Collision-Avoidance Assist (FCA) system relies on a sophisticated array of sensors strategically placed
around your Kia Carnival to monitor the environment. The precision of these sensors is vital for the system's overall
reliability.
Front camera
Front radar
Front corner radar (if equipped)
Rear corner radar (if equipped)
Please refer to the illustrations provided above for the precise locations of your Kia Carnival detecting sensors.
CAUTION
-
Integrity: Never attempt to disassemble, modify, or strike the detecting sensors. Any physical
interference can permanently compromise their calibration.
-
Professional Service: If any sensor is replaced or repaired, the vehicle must be inspected and
recalibrated by an authorized Kia dealer to ensure system accuracy.
-
Impact awareness: If your Kia Carnival experiences an impact near a sensor area, the FCA may
not operate as intended, even if no warning light is illuminated. Always have the vehicle inspected after a
collision.
-
Windshield care: Do not install stickers, accessories, or apply aftermarket tinting to the
windshield near the front camera, as this will obstruct the vision of the Driver Assistance systems.
-
Moisture control: Always ensure the front view camera area remains dry and free of
condensation.
-
Reflective objects: Never place reflective items (like white paper or mirrors) on the
instrument panel, as reflections can blind the sensors.
-
Obstruction prevention: Do not place objects on the dashboard or near the windshield, as they
can interfere with the defogging system, leading to poor visibility and sensor errors.
-
Front radar protection: Do not apply bumper stickers, films, or guards near the front radar
cover. Any non-factory addition can severely attenuate radar signals.
-
Cleaning protocol: Keep the front radar and its cover clean and free of debris. Use only a
soft cloth; never use high-pressure water spray, as this can penetrate seals and damage the electronics.
-
Genuine parts: Only use Kia Genuine Parts for sensor covers. Painting or modifying these
covers will cause the FCA to malfunction. Use only authorized components to maintain the safety standards of
your Kia Carnival.
-
Body repairs: If the bumper is replaced or painted, the sensors may require recalibration.
Always perform this work at an authorized service center.
-
External attachments: Installing a trailer or carrier may obstruct the sensors or alter the
vehicle’s profile, which can negatively affect the performance of the Forward Collision-Avoidance Assist.
