- It will operate if the vehicle speed is
greater 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 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.

Driving your vehicle
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.

Second stage alert
A warning chime to alert the driver
will activate when:
1. A vehicle has been detected in theblind spot area by the radar system
(the warning light will illuminate on
the outside rearview mirror (i.e., in
the first stage alert)
AND
2. The turn signal is applied (same side as where the vehicle is being
detected).
When this alert is activated, the
warning light on the outside rearview
mirror will also blink. If you turn off the turn signal indica-
tor, the second stage alert (the warn-
ing chime and the blinking warning
light on the outside rearview mirror)
will be deactivated.
- The second stage alarm can be
deactivated.
To activate the alarm: Go to the User Settings Mode →
Driver Assistance and select
“Blind-Spot Collision Warning” on
the LCD display.
To deactivate the alarm: Go to the User Settings Mode →
Driver Assistance and deselect
“Blind-Spot Collision Warning” on
the LCD display.
Detecting sensor
The sensors are located inside the
rear bumper.
Always keep the rear bumper clean
for the system to work properly.

Driving your vehicle
(Continued)
• When you replace the windshieldglass, front view camera or related
parts of the steering, take your
vehicle to an authorized Kia deal-
er and have the system checked to
need a calibration.
• The system detects lane markers and controls the steering wheel by
a front view camera, therefore, if
the lane markers are hard to
detect, the system may not work
properly. Always be cautious when
using the system.
• When the lane markers are hard to detect, please refer to “Driver’s
Attention”.
• Do not remove or damage the related parts of LKA.
• Do not place objects on the crash pad that reflects light such as mir-
rors, white paper, etc. it may cause
malfunction of LKA if the sunlight
is reflected. (Continued)(Continued)
• You may not hear warning sound
of LKA because of the excessive
audio sound.
• If you continue to drive with your hands off the steering wheel, the
LKA will stop controlling the
steering wheel after the hands off
alarm. After then, if you drive
with your hands on the steering
wheel, the control will be activated
again.
• If the vehicle speed is high, steer- ing torque for assistance will not
be enough to keep your vehicle
within the lane. If so, the vehicle
may move out of its lane. Obey
speed limit when using LKA.
• If you attach objects to the steer- ing wheel, the system may not
assist steering.
• If you attach objects to the steer- ing wheel, hands off alarm may
not work properly.LKA operation
To activate/deactivate the LKA:
With the ignition switch in the ON
position, press the LKA button locat-
ed on the instrument panel on the
lower left hand side of the driver.
The indicator in the cluster display
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
If you press the LKA button again,
the indicator on the cluster display
will go off.

✽ ✽
NOTICE- Remodeling
Prohibited
Do not rewire your vehicle in any
way as doing so may affect the per-
formance of several safety features
in your vehicle. Rewiring your vehi-
cle may also void your warranty and
cause you to be responsible for any
subsequent vehicle damage which
may result.
✽ ✽ NOTICE- Window tinting pre-
caution
Window tint (especially metallic
film) might cause communication
errors or poor radio reception, and
malfunctioning automatic lighting
system due to reflections from the
mirror tint inside the vehicle. The
solution used might also leak into
the electronic components, causing
malfunctions or damage.
Inner panel fuse replacement
1. Turn the ignition switch and all other switches off.
2. Open the fuse panel cover.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
To identify the location of a specific
fuse, please refer to the inside of the
fuse panel cover and the description
list in this section.
CAUTION
Visually inspect the battery cap to ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.
WARNING
- Electrical wiring repairs
All electrical repairs should be
performed by authorized Kia
dealerships using approved Kia
parts. Using other wiring com-
ponents, especially when retro-
fitting AVN or theft alarm sys-
tem, remote engine control, car
phone or radio may cause vehi-
cle damage and increase the
risk of a vehicle fire.
