- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, 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, 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.

Prerequisite for activation
The FCA gets ready to be activated,
when the FCA is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- Vehicle speed is over 5 mph (8 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a vehicle or pedestrian in front, which may col-
lide with your vehicle. (The FCA
may not be activated or may sound
a warning alarm in accordance
with the driving situation or vehicle
condition.)
❈ The FCA may not operate properly
according to the frontal situation,
the direction and speed of pedes-
trian.
FCA warning message and
system control
The FCA system produces warning
messages, warning alarms, and
emergency braking based on the
level of risk of a frontal collision, such
as when a vehicle ahead suddenly
brakes.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
WARNING
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the FCA system.
The FCA automatically acti- vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the FCA by canceling
the system setting on the LCD
display. To avoid driver dis-
tractions, do not attempt to
set or cancel the FCA while
driving the vehicle.
The FCA automatically deac- tivates upon canceling the
ESC (Electronic Stability
Control). When the ESC is
canceled, the FCA cannot be
activated on the LCD display.
The FCA warning light will
illuminate, but it does not
indicate a malfunction of the
system.

Collision Warning (1st warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- Your vehicle speed may decelerate
moderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision. - It will operate if the vehicle speed is
greater than 5 mph (8 km/h) and
less than or equal to 50 mph (80
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)
Emergency braking (2nd warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- The FCA system limitedly controlsthe brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.

Driving your vehicle
- It will operate if the vehicle speed isgreater than 5 mph (8 km/h) and
less than or equal to 110 mph (180
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)Brake operation
In an urgent situation, the FCAsystem applies the brakes.
The FCA provides additional brak- ing 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 FCA brake control is automat- ically canceled, when risk factors
disappear.
CAUTION
The driver should always paygreat caution to vehicle opera-tion, even though there is nowarning message or warningalarm. The warning of the FCAsystem may not sound whileother system warning sounds.
WARNING
The FCA system logic assesses
the risk of a collision by moni-
toring several variables, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions, such
as inclement weather and road
conditions, may affect the oper-
ation of the FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA cannot avoid all colli-
sions. The braking control can-
not completely stop the vehicle.
The driver is responsible to
safely drive and control the
vehicle.

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.

Limitation of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle or a pedestrian
ahead in the roadway through radar
signals and camera recognition to
warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle 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.WARNING
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.
(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.
The FCA system operates only to detect vehicles and pedestri-
ans in front of the vehicle.

Driving your vehicle
The vehicle in front is moving verti-cally to the driving direction
The vehicle in front is stopped ver- tically
The vehicle in front is driving towards your vehicle or reversing
You are on a roundabout and the vehicle in front circles
- 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 in
the same lane may not be recog-
nized. The FCA system may produce
the warning message and the warn-
ing alarm, or apply the braking con-
trols, prematurely, or it may not pro-
duce the warning message or the
warning alarm, or apply the braking
controls, at all. When driving on a curve, the driver
must maintain a safe braking dis-
tance, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance.

The FCA system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may alarm
the driver and apply the brake. Always
pay attention to road and driving con-
ditions while driving. If necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Always check the traffic conditions
around the vehicle. - Driving on a slope
The FCA performance may be limit-
ed while driving upward or downward
on a slope and may not recognize
the vehicle in front in the same lane.
It may produce the warning message
and the warning alarm prematurely
or it may not produce the warning
message and the warning alarm pre-
maturely at all.
When the FCA suddenly recognizes
the vehicle 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 a safe dis-
tance.
