heavy rain, heavy snow, and fog, or
when sensor is covered by foreign
material, dust, tec., the sensors will
be degraded and the function will be
temporarily disabled.
Always keep the sensor clean.✽ ✽
NOTICE
• Do not install any accessories,
such as license plate molding or
sticker, on the sensor area. Nor
arbitrarily replace the bumper.
Those may adversely affect the
sensing performance.
• Always keep the sensor/bumper
area clean.
• Use only soft cloths to wash the
vehicle. Also, do not spray highly-
pressurized water on the sensor
installed on the bumper.
• Be careful not to apply unneces-
sary force on the frontal sensor
area. When the sensor moves out
of the correct position due to
external force, the function may
not normally operate even without
the warning light or message. In
this case, have your vehicle
inspected by an authorized Kia
dealer.
• Use only the genuine Kia sensor
cover. Do not arbitrarily apply
paint on the sensor cover.
(Continued)(Continued)
• Do not tint the window or install
stickers, accessories around the
inside mirror where the camera is
installed.
• Make sure the front view camera
installation point does not get wet.
• Do not impact or arbitrarily
remove any front radar compo-
nents.
• Do not place reflective
objects(white paper or mirror etc.)
on the crash pad.
The function may activate unnec-
essarily due to reflect of the sun-
light.
• Excessive audio volume may dis-
turb the sound of the function
warning alarm.

Warning message and warning
light
If the sensor or sensor cover is cov-
ered by bad weather or foreign
objects, dust, etc., FCA operation
may temporarily stop. In this case,
the warning message appears to
warn the driver.
This is not a malfunction with FCA. To
operate FCA again, remove the for-
eign substances.
FCA may not properly operate when
the front radar is contaminated or an
object such as an open area is not
existed after engine start.
Function malfunction
When FCA is not working properly,
FCA warning light ( ) will illumi-
nate and the warning message will
appear for a few seconds. After the
message disappears, the master
warning light ( ) will illuminate. In
this case, have your vehicle inspect-
ed by an authorized Kia dealer.
FCA warning message may
appear along with the illumination
of the ESC warning light.
WARNING
FCA may not activate without
any warning messages accord-
ing to driving condition, traffic
on the road, weather, road con-
dition, etc.

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.

den lane changes unexpectedly.- Driving on a curve
The performance of Forward
Collision-Avoidance Assist may be
limited when driving on a curved
road.
The front view camera or front radar
sensor recognition function may not
detect the vehicle, pedestrian or
cyclist traveling in front on a curved
road.
This may result in no alarm and brak-
ing when necessary.

- 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 or front radar sensor recog-
nition may not detect the vehicle,
pedestrian or cyclist in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the function suddenly recog-
nizes the vehicle, pedestrian or
cyclist 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, 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.
Detecting pedestrian or cyclist
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the front view camera
recognition function, 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 function
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 pedestrian, cyclists or a large
crowd
There is an item similar in shape or
appearance to a person
The pedestrian or cyclist is below
the sensor's viewing range
The sensor can not identify the
pedestrian's outline because of
other items changing their profile,
such as mobility assistance devices
The front view camera or front
radar is obstructed by a foreign
object or debris
Inclement weather such as heavy
rain or snow obscures the field of
view of the front radar sensor or
front view 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 color of indicator will change
depend on the condition of LKA.
- White : Sensor does not detect
the lane marker or vehicle
speed is less than 40 mph
(60 km/h).
- Green : Sensor detects the lane
marker and function is
able to control the steer-
ing.Function setting
The driver can change LKA to Lane
Departure Warning (LDW) or change
the LKA mode from the LCD display.
“User Settings Driver Assistance 
Lane Safety Lane Keeping
Assist/Lane Departure Warning/Off ”
Lane Keeping Assist
LKA mode guides the driver to keep
the vehicle within the lanes. It rarely
controls the steering wheel, when
the vehicle drives well inside the
lanes. However, it starts to control
the steering wheel, when the vehicle
is about to deviate from the lanes.
Lane Departure Warning
LDW warns the driver with a visual
and acoustic warning when the func-
tion detects the vehicle leaving the
lane. In this mode, the steering wheel
will not be controlled. When the vehi-
cle’s front wheel contacts the inside
edge of lane line, the contacted line
will be displayed on the LCD display.
Off
If you select ‘Off’, it is the same with
pressing Lane Safety ( ) button
to release.
