FCA system may work when it
recognizes objects similar in shape or
property to a vehicle, pedestrian or
cyclist.
FCA system is designed to help detect
and monitor the vehicle ahead or detect
a pedestrian or cyclist in the roadway
through radar signals and camera
recognition. It is not designed to detect
bicycles, motorcycles, or smaller
wheeled objects such as luggage bags,
shopping carts, or strollers.
Never try to test the operation of FCA
system. Doing so may cause severe
injury or death.
If the front bumper, front glass, radar or
camera have been replaced or repaired,
have the vehicle inspected by an
authorized HYUNDAI dealer.
Information
In some instances, FCA system
may be cancelled 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

Forward Collision-Avoidance
Assist - Junction Turning (if
equipped)
FCA-Junction Turning function is

ahead in advance with the front view
camera and the front radar. It produces
warning messages or haptic warning
alarms in accordance with the collision
risk levels.
