FCA Warning Message and
System Control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, or insufficient braking dis-
tance detection. Also, it controls the
brakes in accordance with the colli-
sion risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Late,
Normal or Early initial warning time.
Collision Warning
(First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle.
- Your vehicle speed may deceler-
ate moderately.
- The FCA system limitedly con-
trols the brakes to preemptively
mitigate impact in a collision.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs to help deceler-
ate the vehicle.
- The FCA system limitedly con-
trols the brakes to preemptively
mitigate impact in a collision. The
brake control is maximized just
before a collision.

Brake operation
The braking system enters into the
ready status to react promptly to
urgent situations.
The FCA provides additional brak-
ing power for optimum braking per-
formance, when the driver depress-
es the brake pedal.
The braking control is automatical-
ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat-
ically canceled, when risk factors
disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
If any other warning sound
such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions such
as inclement weather and road
conditions may affect the oper-
ation of the FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.

System Not Operating
Check Forward Collision Avoidance
Assist system
When the FCA is not working prop-
erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized HYUNDAI dealer.
The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light and the FCA
is automatically deactivated.

Even if there is any problem
with the brake control function
of the FCA system, the vehi-
cle's basic braking perform-
ance will operate normally.
However, brake control func-
tion for avoiding collision will
not activate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
unintentionally activate. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front camera recognition sys-
tem may not detect the vehi-
cle ahead. The FCA system
may not activate and the
warning message will not be
displayed.

Limitations of the System
The Forward Collision-Avoidance
Assist (FCA) system is designed to
help monitor the vehicle ahead in the
roadway through camera recognition
to warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.
In certain situations, the camera may
not be able to detect the vehicle
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to help detect vehicles in
front of the vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
WARNING

- Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the FCA system may activate
prematurely.
Also, in certain instances the front
camera recognition system may not
detect the vehicle traveling on a
curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.The FCA system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Check the surrounding traffic condi-
tions before use.- Driving on a slope
The performance of the FCA decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the FCA suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, the FCA system may
not immediately detect the new vehi-
cle that is now in front of you. In this
case, you must maintain a safe brak-
ing distance, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain a safe distance.- 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, addi-
tional special attention is required.
The FCA system 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 nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
