Forward Collision-Avoidance Assist
system is designed to detect the
vehicle, a pedestrian or cyclist ahead (if
equipped) in the roadway through front
radar signals and front view camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist system:
• This system is only a supplemental
system and it is not intended to,
nor does it replace the need for
extreme care and attention of
the driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the road
conditions at all times.
• Drive at posted speed limits and
accordance to road conditions.
• Always drive cautiously to prevent
unexpected and sudden situations
from occurring. FCA does not always
stop the vehicle completely.

• Selecting Warning Timing
The driver can select the initial
warning activation time from the
User Settings in the LCD display
or infotainment system display (if
equipped) by selecting ‘User Settings
→ Driver Assistance → Warning Timing
→ Normal/Later’.
The options for the initial Forward
Collision Warning includes the following:
- Normal: When this option is selected, the
initial Forward Collision Warning
is activated sensitively. If you feel
the warning activates too early, set
Forward Collision Warning to ‘Later’.
Even though, ‘Normal’ is selected if
the front vehicle suddenly stops the
initial warning activation time may not
seem fast. - Later:
When this option is selected, the initial
Forward Collision Warning is activated
later than normal. This setting reduces
the amount of distance between
the vehicle, pedestrian or cyclist (if
equipped) ahead before the initial
warning occurs.
Select ‘Later’ when traffic is light and
when driving speed is slow.
When you accelerate suddenly to the
vehicle ahead, the warning may seem
to activate earlier even if ‘Later’ is
selected.

If you change the warning timing, the
warning timing of other systems may
change.

‘Active Assist’ or ‘Warning Only’ under
Forward Safety is selected in the cluster
LCD display, and when the following
prerequisites are satisfied.
- ESC (Electronic Stability Control) is on.
- Vehicle speed is over 6 mph (10 km/h ).
(FCA is only activated within a certain
speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which may
collide with your vehicle. However,
FCA may not be activated or may only
sound a warning alarm depending on
the driving or vehicle conditions.
FCA may not operate properly according
to the frontal situation, condition of the
vehicle, the direction of pedestrian or
cyclist or speed. If you select "Warning

cannot be activated in the LCD display
or infotainment system display (if
equipped). In this situation, the FCA
warning light will illuminate which is
normal.
FCA Warning Message and Brake
Control
FCA produces warning messages,
warning alarms, and emergency braking
based on the level of risk of a frontal
collision, such as when a vehicle ahead
suddenly brakes, or the system detects
that a collision with a pedestrian or
cyclist is imminent.

arning light () will illuminate and the
warning message will appear for a few
seconds. After the message disappears,
the master warning light (
) will
illuminate. In this case, have the vehicle
inspected by an authorized HYUNDAI

WARNING
• FCA is only a supplemental system
for the driver's convenience. The
driver should hold the responsibility
to control the vehicle operation. Do
not solely depend on FCA system.
Rather, maintain a safe braking
distance, and, if necessary, depress
the brake pedal to reduce the driving
speed or to stop the vehicle.
• In certain instances and under
certain driving conditions, FCA
system may activate unintentionally.
This initial warning message appears
on the LCD display with a warning
chime.
Also due to sensing limitations, in
certain situations, the front radar
sensor or camera recognition
system may not detect the vehicle,
pedestrian or cyclist (if equipped)
ahead. FCA system may not activate
and the warning message may not be
displayed.
• Even if there is any problem with
the brake control function of FCA
system, the vehicle’s basic braking
performance will operate normally.
However, brake control function for
avoiding collision will not activate.

While Driving6-54
• The pedestrian or cyclist is not fully detected by the camera recognition
system, for example, if the pedestrian
is leaning over or is not fully walking
upright
• The pedestrian or cyclist is moving very quickly or appears abruptly in the
camera detection area
• The pedestrian or cyclist is wearing clothing that easily blends into the
background, making it difficult to be
detected by the camera recognition
system
• The outside lighting is too bright (e.g. when driving in bright sunlight or
in sun glare) or too dark (e.g. when
driving on a dark rural road at night)
• It is difficult to detect and distinguish the pedestrian or cyclist from other
objects in the surroundings, for
example, when there is a group of
pedestrians, cyclists or a large crowd
• There is an item similar to a person’s body structure
• The pedestrian or cyclist is small
• The pedestrian has impaired mobility
• The sensor recognition is limited • 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
• 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 windshield glass is fogged up; a clear view of the road is obstructed
• The adverse road conditions cause excessive vehicle vibrations while
driving
• The sensor recognition changes suddenly when passing over a speed
bump
• You are on a roundabout
• The pedestrian or cyclist suddenly interrupts in front of the vehicle
• The cyclist in front is riding intersected with the driving direction
• There is any other electromagnetic interference
• The construction area, rail or other metal object is near the cyclist
• The bicycle material is not reflected well on the radar
WARNING
Turn off Forward Collision avoidance
Assist system through cluster or
infotainment system before towing
a vehicle. Application of 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.
