Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.
If a tire goes flat while you are driv- ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.
If your vehicle is equipped with an Automatic Transmission, don't let
your vehicle creep forward. To
avoid creeping forward, keep your
foot firmly on the brake pedal when
the vehicle is stopped.
Be cautious when parking on a hill. Firmly engage the parking brake
and place the shift lever in P (auto-
matic transmission). If your vehicle
is facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling. If your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.
Under some conditions your park- ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P (automatic
transmission) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on an incline with the accelerator pedal.
This can cause the transmission to
overheat. Always use the brake
pedal or parking brake.Electronic control suspension(ECS) (if equipped)
The Electronic Control Suspension
(ECS) controls the vehicle suspen-
sion automatically to maximize driv-
ing comfort by taking into account
the driving conditions such as speed,
surface of the road, cornering, stop-
ping requirements and acceleration.
If the ECS warning message “Check
ECS” comes on, you may have a
problem with the ECS system. In this
case, have the vehicle inspected by
an authorized K900 Kia dealer
immediately.

The Forward Collision-avoidance
Assist (FCA) system is designed to
help detect and monitor the vehicle
ahead or help detect a pedestrian in
the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent,
and if necessary, apply emergency
braking.
System setting and activation
System setting
The driver can activate the FCA byplacing the ignition switch to the
ON position and by selecting:
"AVN →Settings →Vehicle →
Driver assistance → Forward safety"
- If you select "Active assistance", the FCA system activates. The
FCA produces warning mes-
sages and warning alarms in
accordance with the collision risk
levels. Also, it controls the brakes
in accordance with the collision
risk levels.
- If you select "Warning only", the FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the
brake directly because the FCA
system do not control the brake.
- If you select "Off", the FCA sys- tem deactivates,
FORWARD COLLISION-AVOIDANCE ASSIST (FCA) SYSTEM - SENSOR FUSION TYPE
(FRONT RADAR + FRONT CAMERA)
WARNING
Take the following precautions
when using the Forward
Collision-avoidance Assist
(FCA) system:
This system is only a supple- mental system and it is not
intended to, nor does it
replace the need for extreme
care and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at all
times.
NEVER drive too fast in accor- dance with the road condi-
tions or while cornering.
Always drive cautiously to prevent unexpected and sud-
den situations from occur-
ring. The Forward Collision
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.

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 on.
- Vehicle speed is over 6 mph (10 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects the 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.)
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 Settings in
the AVN. The options for the initial
Forward Collision Warning include
Normal or Late initial warning time.
WARNING
Completely stop the vehicleon 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.
The FCA automatically deacti- vates 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
which is normal.

Collision Warning (First 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. - If you select "Warning only", for the
FCA system setting, the FCA sys-
tem activates and produces only
warning alarms in accordance with
the collision risk levels. You should
control the brake directly because
the FCA system will not control the
brake.
Emergency braking
(Second 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 decel-
erate the vehicle.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.

Driving your vehicle
- If you select "Warning only", for theFCA system setting, the FCA sys-
tem activates and produces only
warning alarms in accordance with
the collision risk levels. You should
control the brake directly because
the FCA system will not control the
brake.Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA system provides addi- tional braking power for optimum
braking performance, 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.
WARNING
The braking control cannotcompletely stop the vehicle
nor avoid all collisions. The
driver is responsible to safely
drive and control the vehicle.
If any other warning sound such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
CAUTION
The driver should always useextreme caution while operatingthe vehicle, whether or not thereis a warning message or alarmfrom the FCA system.

The system will operate normally
when such dirt, snow or debris is
removed.
However, the FCA may not properly
operate in an area (e.g. open ter-
rain), where any substances are not
detected or the camera is blocked
with dirt, snow or debris after turning
ON the engine.
Also, even though a warning mes-
sage does not appear on the LCD
display, the FCA may not properly
operate.System malfunction
Check Forward Collision Avoidance
Assist system
When the FCA is not working prop-
erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
have the system checked by an
authorized K900 Kia dealer.
The FCA warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
ORJ058165L
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.
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, due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle ahead. The
FCA system may not activate
and the warning message
may not be displayed.

Even if there is any problemwith 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.
If the vehicle in front stops suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti- vate if the driver applies the
brake pedal to avoid the risk
of a collision.
(Continued)(Continued)
The brake control may beinsufficient, 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
conditions, inclement weath-
er, driving conditions or traffic
conditions.
Occupants may get injured, if the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates only to detect vehicles in front
of the vehicle.WARNING
The FCA system operatesonly to help detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not operate 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 oppo-
site 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 vehi-
cle (for example on a dead
end street.)

Limitations of the system
The Forward Collision avoidance
assist (FCA) system is designed to
monitor the vehicle or 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 or pedestrian
ahead. In these cases, the FCA sys-
tem 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 radar sensor or camera is
blocked 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 sensor recogni- tion is limited
The vehicle in front is too small to be detected (for example a motor
cycle, 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 tractor
trailer, etc.)(Continued)
The FCA system cannotdetect any cross traffic
cyclists that are approaching.
In these cases, you must
maintain a safe braking dis-
tance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis-
tance.

- 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 prematurely, or it may not
produce the warning message or the
warning alarm 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 unnec-
essarily alarm the driver and 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 depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Always check the traffic conditions
around the vehicle.

Driving your vehicle
- Driving on a slope
The performance of the FCA may be
limited while driving upward or down-
ward on a slope any may not recog-
nize the vehicle in front in the same
lane. It may unnecessarily produce
the warning message and the warn-
ing alarm prematurely, or it may not
produce the warning message and
the warning alarm 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.
- 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.
