In an angled collision, the force of
impact may direct the occupants in
a direction where the air bags
would not be able to provide any
additional benefit, and thus the
sensors may not deploy any air
bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehi-
cle causing it to “ride” under a vehi-
cle with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because
deceleration forces that are detect-
ed by sensors may be significantly
reduced by such “under-ride” colli-
sions. Front air bags may not inflate in all
rollover accidents where the
SRSCM indicates that the front air
bag deployment would not provide
additional occupant protection.

Types of warning sound
When an object is 47 in. to 24 in.(120 cm to 61 cm) from the rear
bumper: Buzzer beeps intermit-
tently.
When an object is 24 in. to 12 in. (60 cm to 31 cm) from the rear
bumper: Buzzer beeps more fre-
quently.
When an object is within 12 in. (30 cm) of the rear bumper:
Buzzer sounds continuously.
Non-operational conditions of
the parking distance warning-
reverse system
The parking distance warning-
reverse system may not operate
properly when:
1. Moisture is frozen to the sensor. (It will operate normally once the
moisture clears.)
2. The sensor is covered with foreign matter, such as snow or water, or
the sensor cover is blocked. (It will
operate normally when the materi-
al is removed or the sensor is no
longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps,
gradient).
4. Objects generating excessive noise (vehicle horns, loud motor-
cycle engines, or truck air brakes)
are within range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the
sensor.
7. The sensor is covered with snow.
8. Trailer towing. The detecting range may decrease
when:
1. The sensor is covered with foreign
matter such as snow or water.
(The sensing range will return to
normal when removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be
recognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sensor frequency such as clothes,
sound absorbent material or snow.
3. Undetectable objects smaller than 40 in. (1 m) in height and narrower
than 6 in. (14 cm) in diameter.

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 system will get deactivat-
ed for the sake of driver's safety
when the ESC warning light comes
on. The FCA warning message will
appear at the same time, too. But
that doesn't necessarily mean the
malfunction of the FCA system.\
Both FCA warning light and warn-
ing message will disappear once
the ESC warning light issue is
resolved.

WARNING
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 neces-
sary, depress the brake pedal
to lower the driving speed.
In certain instances and under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
ahead. The FCA system may
not activate and the warning
message will not be dis-
played.

Driving your vehicle
Limitation of the system
The FCA is an assistant system for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
The FCA monitors the driving situa-
tions through the radar and the cam-
era sensor. Thus, for a situation out
of the sensing range, the FCA may
not normally operate. The driver
should pay great caution in the fol-
lowing situations. The FCA operation
may be limited.
Recognizing vehicles
The sensor may be limited when:
The radar sensor or camera isblocked 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
There is severe irregular reflection from the radar sensor
The radar/camera sensor recogni- tion 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 camera recog-
nition system (for example a tractor
trailer, etc.)(Continued)
The FCA system cannotdetect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.) In these cases,
you must maintain a safe
braking distance, and if nec-
essary, depress the brake
pedal to reduce the driving
speed in order to maintain a
safe distance.
The regular braking function will operate normally even if
there is a problem with the FCA
brake control system or other
functions. In this case, the brak-
ing control will not operate in
the risk of a collision.
The FCA system may not acti- vate according to driving con-
dition, traffic on the road,
weather, road condition, etc.
The FCA system may not acti- vate to all types of vehicles.

Driving your vehicle
- Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
On curved roads, the other vehicle
on the same lane is not recognized
and the FCA system's performance
may be degraded. This may produce
the warning message and the warn-
ing alarm prematurely, or it may not
produce the warning message or the
warning alarm at all.Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road. When
driving on a curve, exercise caution,
maintain 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 an adjacent lane when
driving on a curved road. In this
case, the system may 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, you may depress
the accelerator pedal to prevent the
system from unnecessarily deceler-
ating your vehicle.
Always check the traffic conditions
around the vehicle.

655
Driving your vehicle
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain 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.
Recognizing pedestrians
- The pedestrian is not fully captured
by the camera sensor, or the
pedestrian does not walk in the
upright position.
- The pedestrian moves very fast.
- The pedestrian abruptly appears in front.
- The pedestrian wears clothes sim- ilar in color to the background.
- Conditions outside are too bright or too dark.
- The vehicle drives at night or in the darkness.
- There is an item similar in shape a person’s body structure.
- The pedestrian is small.
- The pedestrian has impaired mobility.
- The pedestrian blends in with their surroundings.
- Sensor recognition is limited by rain, snow, fog, etc.
- There is a group of pedestrians.
