The pedestrian 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 is moving very
quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system

- If you select 'Warning only', FCA
system activates and produces
only warning alarms in accor-
dance with the collision risk lev-
els. Braking assist will not be
applied in this setting.
- If you select 'Off', FCA system
deactivates,
The warning light illumi-
nates on the instrument
cluster, when you cancel
FCA system. The driver
can monitor the FCA ON/OFF status
on the LCD display. Also, the warning
light illuminates when the ESC
(Electronic Stability Control) is
turned off.
- If the warning light remains ON
when FCA is activated, we recom-
mend that you have the system
checked by an authorized
HYUNDAI dealer. Selecting Warning Timing
The driver can select the initial
warning activation time from the
User Settings in the cluster LCD
display by selecting 'User settings
→Driver assistance →Warning
timing →Normal/Late'.
The options for the initial Forward
Collision Warning includes the fol-
lowing:
- Normal:
When this option is selected, the
initial Forward Collision Warning is
activated sensitively. If you feel the
warning activates too early, set the
Forward Collision Warning to
'Late'.Even though, 'Normal' is selected if
the front vehicle suddenly stops
the initial warning activation time
may not seem fast.
- Late:
When this option is selected, the
initial Forward Collision Warning is
activated later than normal. This
setting reduces the amount of dis-
tance between the vehicle, pedes-
trian or cyclist ahead before the ini-
tial warning occurs.
Select 'Late' 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
'Late' is selected.
Information
If you change the warning timing, the
warning timing of other systems may
change. Always be aware before
changing the warning timing.

Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites are
satisfied.
- ESC (Electronic Stability Control)
is on.
- Vehicle speed is over 5 mph (8
km/h). (FCA is only activated with-
in a certain speed range.)
- The system detects a pedestrian,
cyclist (if equipped) 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,
the direction of pedestrian or
cyclist (if equipped) and speed.
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 (if
equipped) is imminent.To avoid driver distractions,
do not attempt to set or can-
cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or canceling
the system.
FCA automatically activates
upon placing the Engine
start/stop button to the ON
position. The driver can deacti-
vate FCA by canceling the sys-
tem setting on the cluster LCD
display.
FCA automatically deactivates
upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.

forcibly moved out of proper
alignment, FCA system may not
operate correctly. In this case, a
warning message may not be
displayed. We recommend that
you have the vehicle inspected
by an authorized HYUNDAI deal-
er.
If the front bumper becomes
damaged in the area around the
front radar sensor, the FCA sys-
tem may not operate properly.
We recommend that you have
the vehicle inspected by author-
ized HYUNDAI dealer.
Use only genuine parts to repair

Driving your vehicle
When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, Forward Collision-
Avoidance Assist system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking dis-
tance, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance. 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 atten-
tion is required. Forward Collision-
Avoidance Assist system may not
be able to detect the cargo extend-
ing 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.
Detecting pedestrians or
cyclists
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the front view 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 front view camera detection
area
The pedestrian or cyclist is wear-
ing clothing that easily blends into
the background, making it difficult
to be detected by the front view
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 distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclists or a large
crowd
