If there is a malfunction with
FCA, the autonomous emer-
gency braking may not be
applied even through the
braking system is operating
normally.
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.
FCA may activate during brak-
ing and the vehicle may stop,
suddenly shifting loose
objects toward the passen-
gers. Always keep loose
objects secured.
FCA may not activate if the
driver applies the brake pedal
to avoid a collision.
(Continued)(Continued)
Even if there is any problem
with the brake control func-
tion of FCA, the vehicle's
basic braking performance
will operate normally.
However, brake control func-
tion for avoiding collisions
may not activate.
FCA operates only to detect
vehicles, pedestrian in front of
the vehicle.
FCA does not operate when
the vehicle is in reverse.
FCA is not designed to detect
other objects on the road
such as animals.
FCA does not detect vehicles
in the opposite lane.
FCA does not detect cross
traffic vehicles that are
approaching.
(Continued)(Continued)
FCA cannot detect the driver
approaching the side view of
a parked vehicle (for example
on a dead end street.) In these
situations, you must maintain
a safe braking distance, and if
necessary, depress the brake
pedal to reduce the driving
speed in order to maintain a
safe distance.
FCA may not activate as a
result of the road conditions,
inclement weather, driving
conditions or traffic condi-
tions.
FCA does not operate for all
vehicles and pedestrian.

- Driving on a curve
The performance of Forward
Collision-Avoidance Assist may be
limited when driving on a curved
road. The front view camera recogni-
tion function may not detect the vehi-
cle or pedestrian traveling in front on
a curved road.This may result in no alarm and
braking when necessary. Always pay
attention to road and driving condi-
tions, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance.

Forward Collision-Avoidance Assist
may recognize a vehicle or pedestrian
in the next lane or outside the lane
when driving on a curved road. If this
occurs, the function may unnecessar-
ily alarm the driver and apply the
brake. Always pay attention to road
and driving conditions, while driving.- Driving on a slope
The performance of Forward
Collision-Avoidance Assist may be
decreased while driving upward or
downward on a slope. The front view
camera recognition may not detect
the vehicle or pedestrian in front.This may result in unnecessary
alarm and braking or no alarm and
braking when necessary. When the
function suddenly recognizes the
vehicle or pedestrian in front while
passing over a slope, you may expe-
rience 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, Forward Collision-
Avoidance Assist may not immedi-
ately detect the vehicle, especially if
the vehicle changes lanes abruptly.
In this case, you must maintain a
safe braking distance, and if neces-
sary, 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 stopped vehicle in front of you
merges out of the lane, Forward
Collision-Avoidance Assist may not
immediately detect the new vehicle
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.- Recognizing the vehicle
When the vehicle in front has heavy
loading extended rearward, or when
the vehicle in front has higher ground
clearance, it may induce a haz-
ardous situation. Always pay atten-
tion to road and driving conditions,
while driving and, if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain distance.

FCA is to reduce or to avoid accident
risk. It recognizes the distance from
the vehicle ahead, the pedestrian or
the cyclist through the sensors (i.e.
front view camera and front radar),
and, if necessary, warns the driver of
accident risk with the warning mes-
sage or the warning alarms and
apply emergency braking.

FCA warning message and
function control
FCA produces warning messages
and warning alarms in accordance
with the collision risk levels of follow-
ings like vehicle’s sudden braking in
front or lack of vehicle distance or
collision to pedestrian or cyclist.
Also, it controls the brakes in accor-
dance with the collision risk levels.
The driver can select the initial warn-
ing activation time in the User set-
tings in the LCD display. The
options for the initial Forward
Collision Warning include Normal or
Late initial warning time.
Collision Warning (1st warning)

Brake operation
In an urgent situation, the braking
system enters into the ready status
for prompt reaction to assist the driv-
er in depressing the brake pedal.
FCA provides additional braking
power for optimum braking per-
formance, when the driver
depresses 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 braking control is automatical-
ly canceled, when risk factors dis-
appear.
Detecting sensors (Front view
camera/Front radar)
The sensors are that detecting the
distance to vehicles ahead, pedestri-
an or cyclist.
CAUTION
The driver should always pay
great caution to vehicle opera-
tion, even though there is no
warning message or warning
alarm.
WARNING
FCA cannot avoid all collisions.
FCA might not completely stop
the vehicle before a collision,
due to ambient, weather and
road conditions. The driver has
the responsibility to drive safely
and control the vehicle.
WARNING
FCA operates in accordance
with certain risk factors, such as
the distance from the
vehicle/passer-by in front, the
speed of the vehicle/passer-by in
front, and the driver's vehicle
operation.ODEP059029

WARNING
FCA is only a supplemental
function for the driver’s con-
venience. The driver has the
ultimate responsibility to con-
trol and operate the vehicle
safely. Do not solely depend
on FCA. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to lower the driving
speed.
In certain instances and
under certain driving condi-
tions, FCA may activate unin-
tentionally. This initial warning
message appears on the LCD
display with a warning chime.
Also, in certain instances the
front view camera or front
radar recognition function
may not detect the vehicle,
pedestrian or cyclist (if
equipped) ahead. FCA may
not activate and the warning
message will not be displayed.
(Continued)
(Continued)
FCA may unnecessarily pro-
duce the warning message
and the warning alarms. Also,
due to the sensing limitation,
FCA may not produce the
warning message and the
warning alarm at all.
When there is a malfunction
with FCA, the braking control
does not operate upon detect-
ing a collision risk even with
other braking systems nor-
mally operating.
FCA operates only for the
vehicle/pedestrian in front,
while driving forward. It does
not operate for any animals or
vehicles in the opposite direc-
tion.
FCA does not recognize the
vehicle, which transversally
drives across the crossroad,
or the vehicle, which is parked
in the transversal direction.
(Continued)(Continued)
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep safe
distance between your vehicle
and the vehicle in front of you.
FCA may activate during brak-
ing and the vehicle may stop
suddenly. And the load in the
vehicle may endanger passen-
gers. Therefore, always be
mindful of the load volume in
the vehicle.
FCA may not activate if the
driver applies the brake pedal
to avoid risk of collision.
FCA does not operate when
the vehicle is in reverse. In
these circumstances, you
must maintain a safe braking
distance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis
tance.

Limitation of the function
FCA is an assistant function for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
FCA monitors the driving situations
through the front radar and the front
view camera sensor. Thus, for a situ-
ation out of the sensing range, FCA
may not normally operate. The driver
should pay great caution in the fol-
lowing situations. FCA operation may
be limited.
Recognizing vehicles
The sensor may be limited when:
The front view camera or front
radar sensor is blocked with a for-
eign object or debris
The front view camera lens is con-
taminated due to tinted, filmed or
coated windshield, damaged
glass, or stuck of foreign matter
(sticker, bug, etc.) on the glass
Inclement weather such as heavy
rain or snow obscures the field of
view of the front radar sensor or
front view camera
There is interference by electro-
magnetic waves
There is severe irregular reflection
from the front view camera sensor
The front view camera/front radar
sensor recognition is limited
The vehicle in front is too small to
be detected (for example a motor-
cycle etc.)
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the front view cam-
era recognition function (for exam-
ple a tractor trailer, etc.)(Continued)
The regular braking function
will operate normally even if
There is a problem with FCA
brake control function or
other functions. In this case,
the braking control will not
operate in an imminent colli-
sion.
FCA may not activate accord-
ing to driving condition, traffic
on the road, weather, road
condition, etc.
FCA may not activate in
response to all types of vehi-
cles.
