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.

Features of your vehicle
When more than two objects aresensed at the same time, the clos-
est one will be recognized first.
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 16 in. (40 cm) of the rear bumper:
Buzzer sounds continuously.
Non-operational conditions of
parking distance warning-
reverse
The parking distance warning-
reverse 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. 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.

Driving your vehicle
Limitation of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle or pedestrians
ahead in the roadway through cam-
era recognition to warn the driver
that a collision is imminent, and if
necessary, apply emergency brak-
ing.
In certain situations, the camera may
not be able to detect the vehicle or
pedestrians ahead. In these cases,
the FCA system may not operate
normally. The driver must pay careful
attention in the following situations
where the FCA operation may be
limited.
Detecting vehicles
The sensor may be limited when:
The camera is covered object ordebris
Inclement weather such as heavy rain or snow obscures the field of
view of the camera
The 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 tunnelWARNING
The FCA system does notoperate 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 opposite
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 vehicle (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.

Driving your vehicle
- 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.
Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detectedby 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 camera is covered with a for- eign 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.
The adverse road conditions cause excessive vehicle vibrations while
driving
When the pedestrian suddenly appears in front of the vehicle
When the construction area, rail or other metal object is near the
pedestrian.

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.
OJF058394L
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.
(Continued)
(Continued)
The FCA system may not acti-vate if the driver applies the
brake pedal to avoid the risk
of a collision.
The brake control may be insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
The FCA system may not acti- vate according to the road con-
ditions, inclement whether,
driving conditions or traffic
conditions.
Even if there is any problem with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
