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, chock
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 chock 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. If this
occurs, have the vehicle inspected
by an authorized K900 Kia dealer
immediately.

Forward Collision-Avoidance Assist
(FCA) system is designed to help
detect and monitor the vehicle ahead
or detect a pedestrian or cyclists 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 FCA sys-tem by pushing the start button
(engine running) and by selecting :
“AVN →Setup →Vehicle →Driver
Assistance →Forward Safety”
- If you select “Active assistance”, FCA system activates. FCA pro-
duces warning messages and
warning alarms in accordance
with the collision risk levels. Also,
it controls the brakes in accor-
dance with the collision risk lev-
els.
- If you select “Warning only”, FCA system activates and produces
only warning alarms in accor-
dance with the collision risk lev-
els. You should control the brake
directly because FCA system do
not control the brake.
- If you select “OFF”, FCA system deactivates,
FORWARD COLLISION-AVOIDANCE ASSIST (FCA) SYSTEM - SENSOR FUSION TYPE
(FRONT CAMERA + FRONT RADAR)
WARNING
Take the following precautions
when using the Forward
Collision-avoidance Assist
(FCA) system:
This system is only a supple- mental system and 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 for the road conditions or while cor-
nering.
Always drive cautiously to prevent unexpected and sud-
den situations from occur-
ring. FCA system does not
stop the vehicle completely
and is not a collision avoid-
ance system.

Prerequisite for activation
FCA system gets ready to be activat-
ed when FCA system is selected on
the LCD display, and when the fol-
lowing prerequisites are satisfied.
- The ESC (Electronic StabilityControl) is on.
- Vehicle speed is over 6 mph (10 km/h). (FCA system is only activat-
ed within a certain speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which
may collide with your vehicle. (FCA
system may not be activated or
may sound a warning alarm in
accordance with the driving situa-
tion or vehicle condition. If you
select "Warning only", FCA system
activates and produces only warn-
ing alarms in accordance with the
collision risk levels.)
❈ FCA system may not operate prop-
erly according to the frontal situa-
tion, the direction of pedestrian or
cyclist and speed.
FCA warning message and
system control
FCA system produces warning mes-
sages, and warning alarms, in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, pedestrian or cyclist detec-
tion. Also, it controls the brakes in
accordance with the collision risk lev-
els.
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

Collision Warning (First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, the engine man-
agement system intervenes to help
decelerate the vehicle.
The Vehicle may slow down slightly.
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.) For pedestrians and cyclists, the
vehicle speed is greater than or
equal to 5 mph (8 km/h) and less
than 40 mph (65 km/h).
(Depending on the condition of
pedestrians and bike riders and
the surrounding environment the
possible maximum operating
speed may be reduced.)
If you select “Warning only”, for FCA system setting, FCA system
activates and produces only warn-
ing alarms in accordance with the
collision risk levels. You should
control the brake directly because
FCA system will not control the
brake.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, the engine management
system intervenes to help decelerate
the vehicle.
The brake control is maximized just
before a collision, reducing impact
when it strikes a forward vehicle.

equal to 5 mph (8 km/h) and less
than 40 mph (65 km/h).
(Depending on the condition of
pedestrians and bike riders and
the surrounding environment the
possible maximum operating
speed may be reduced.)
If you select “Warning only”, for FCA system setting, FCA system
activates and produces only warn-
ing alarms in accordance with the
collision risk levels. You should
control the brake directly because
FCA system will not control the
brake.Brake operation
In an emergency situation, thebraking system enters in ready sta-
tus for prompt reaction upon the
driver depressing the brake pedal.
FCA system provides additional braking power for optimum braking
performance when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated when the driver
depresses the accelerator pedal
quickly, or when the driver abruptly
operates the steering wheel.
FCA system brake control is auto- matically canceled when risk fac-
tors disappear.
WARNING
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
CAUTION
The driver should always useextreme caution while operatingthe vehicle, whether or not thereis a warning message or alarmfrom FCA system.

WARNING
FCA is only a supplementalsystem for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on 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, FCA system may acti-
vate unintentionally. This ini-
tial 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
or cyclist ahead. FCA system
may not activate and the
warning message may not be
displayed.

WARNING
FCA System may not activate
according to the road condi-
tions, inclement weather, driv-
ing conditions or traffic condi-
tions.

Driving your vehicle
(Continued)
Even if there is any problemwith the brake control func-
tion of FCA system, the vehi-
cle's basic braking perform-
ance will operate normally.
However, the brake control
function of FCA for avoiding a
collision will not activate.
If the vehicle in front stops suddenly, you may have less
time to apply the brakes.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
FCA system may activate dur- ing braking and the vehicle
may stop suddenly shifting
loose objects toward the pas-
sengers. Always keep loose
objects secured.
FCA system may not activate 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.
Occupants may get injured, if the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.WARNING
FCA system operates only todetect vehicles, pedestrians
or cyclist in front of the vehi-
cle.
FCA system does not operate when the vehicle is in reverse.
FCA system is not designed to detect other objects on the
road such as animals.
FCA system does not detect vehicles in the opposite lane.
FCA system does not detect cross traffic vehicles that are
approaching.

Limitations of the system
Forward Collision-Avoidance Assist
(FCA) system is designed to monitor
the vehicle or pedestrian or cyclist
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 sensor
or the camera may not be able to
detect the vehicle or pedestrian or
cyclist ahead. In these cases, FCA
system may not operate normally.
The driver must pay careful attention
in the following situations where FCA
operation may be limited.
Detecting vehicles
The sensor may be limited when:
The system may not work around
15 seconds after starting the vehi-
cle or the initialization or rebooting
of the front view camera.
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 cam-
era.
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.).(Continued)
FCA system cannot detectany 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 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 FCA system's performance may
be degraded. This may result in
unnecessary alarm or braking or no
alarm or braking when necessary.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road. In these cases, the driver 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 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.
FCA system may recognize a vehicle
in the next lane when driving on a
curved road.
In this situation, the system may
unnecessarily 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.
Check to be sure that the road con-
ditions permit safe operation of FCA
system.

Driving your vehicle
- Driving on a slope
The performance of FCA system
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane.
It may unnecessarily produce the
warning message and the warning
alarm, or it may not produce the
warning message and the warning
alarm at all.
When FCA system suddenly recog-
nizes the vehicle in front while pass-
ing 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 distance.
- Changing lanes
When a vehicle changes lanes in
front of you, FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this situation, you must
maintain a safe braking distance,
and if necessary, depress the brake
pedal to reduce your driving speed in
order to maintain a safe distance.
