• If the front bumper becomes dam-aged in the area around the radar
sensor, the FCA system may not
operate properly. In this case, we
recommend you have the vehicle
inspected by an authorized Kia
dealer.
• Use only genuine parts to repair or replace a damaged sensor or sen-
sor cover. Do not paint to the sen-
sor cover.
• Never install any accessories or stickers on the front windshield,
or tint the front windshield.
• Never place any reflective objects (i.e. white paper, mirror) over the
dashboard. Any light reflection
may cause a malfunction of the
system.
• Make sure the frontal camera does not get wet.
• Never disassemble the camera assembly, or apply any impact on
the camera assembly.
• Playing the vehicle audio system at high volume may prevent occu-
pants from hearing the FCA warn-
ings. (Continued)(Continued)
• Be careful not to apply unneces-
sary force on the sensor. If the sen-
sor is forcibly moved out of proper
alignment, the system may not
operate correctly. In this case, a
warning message may not be dis-
played. In this case, we recom-
mend you have the vehicle inspect-
ed by an authorized Kia dealer.Warning message and warning
light
When the cover is covered with dirt,
snow, or debris, the FCA system
operation may not be able to detect
vehicles.
If this occurs, a warning message will
appear on the LCD display.
Remove any dirt, snow, or debris and
clean the sensor before operating
the FCA system.

The system will operate normally
when such dirt, snow or debris is
removed.
However, the FCA system may not
properly operate in an area (e.g.
open terrain), where any substances
are not detected after turning ON the
engine.
Although a warning message will not
appear on the LCD display, the FCA
may not properly operate.System malfunction
When the FCA is not working prop-
erly, the FCA warning light ( ) will
illuminate and the warning mes-
sage will appear for a few seconds.
After the message disappears, the
master warning light ( ) will illu-
minate. In this case, have the vehi-
cle inspected by an authorized Kia
dealer.
The FCA warning message may appear along with the illumination
of the ESC warning light.

WARNING
The FCA is only a supplemen-tal system for the driver's con-
venience. It is the driver's
responsibility to control 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 or stop the vehicle.
In certain instances and under certain driving condi-
tions, the FCA system may
activate unintentionally.
Also, due to sensing limita-
tions, in certain situations,
the front radar sensor or front
view camera recognition sys-
tem may not detect the vehi-
cle or pedestrians ahead. The
FCA system may not activate
and the warning message
may not be displayed.

Detecting vehicles
The sensor may be limited when:
The radar sensor or camera is cov-
ered with a foreign object or debris
The camera lens is contaminated 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 radar sensor or camera
There is interference by electro- magnetic waves
Something in the path of travel deflects the radar waves.
The radar/camera recognition is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system. (for example a trac-
tor, trailer, etc.) The camera's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
or their rear lights are located
unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
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 or head-
light of oncoming vehicle.
The windshield glass is fogged up
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.
The vehicle is drives inside a build- ing, such as a basement parking lot
The camera does not recognize the entire vehicle in front.
The camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
Adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump
The shadow is on the road by a median strip, trees, etc.
The vehicle drives through a toll- gate.
The rear part of the vehicle in front is not fully visible.

Detecting pedestrians
The sensor may be limited when:
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
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 from other
objects in the surroundings, for
example, when there is a group of
pedestrians, or a large crowd. There is an item similar to a per-
son's body structure
The pedestrian is small
The pedestrian has impaired mobility
The sensor recognition is limited
The radar sensor or camera is cov- ered 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.
Adverse road conditions cause excessive vehicle vibrations while
driving
When the pedestrian suddenly appears in front of the vehicle
When there is any other electro- magnetic interference When a construction area, rail or
other metal object is near the
pedestrian.
WARNING
Do not use the ForwardCollision -Avoidance Assist
(FCA) system when towing a
vehicle. Application of the
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.
The FCA system is designed to detect and monitor the
vehicle ahead in the roadway
through radar signals and
camera recognition. It is not
designed to detect bicycles,
motorcycles, or smaller

Driving your vehicle
On inclines
During uphill or downhill driving,the smart cruise control system
may not immediately detect a mov-
ing vehicle in your lane, and may
cause your vehicle to accelerate to
the set speed. Also, the vehicle
speed will rapidly down when the
vehicle ahead is recognized sud-
denly.
Select the appropriate set speed on inclines and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road and driving conditions ahead.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme- diately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a vehicle which moves into your lane is slower than your vehicle,
your speed may decrease to main-
tain the distance to the vehicle
ahead. If a vehicle which moves into your
lane is faster than your vehicle,
your vehicle will accelerate to the
selected speed.
