Driving your vehicle
The camera's field of view is notwell illuminated (either too dark or
too much reflection or too much
backlight that obscures the field of
view)
The vehicle in front does not have their rear lights or their rear lights
does not turned ON or their rear
lights are located unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
When light coming from a street light or an oncoming vehicle is
reflected on a wet road surface

field of view in front is obstructed
by sun glare
The windshield glass is fogged up; a clear view of the road is obstruct-
ed
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or road
with sudden gradient changes. The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.
The vehicle drives inside a build- ing, such as a basement parking
lot
The camera does not recognize the entire vehicle in front.
The camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
The shadow is on the road by a median strip, trees, etc.
The vehicle drives through a toll- gate.
The windshield glass is fogged up; a clear view of the road is obstruct-
ed.
The rear part of the vehicle in front is not normally visible. (the vehicle
turns in other direction or the vehi-
cle is overturned.)
The adverse road conditions cause excessive vehicle vibrations while
driving The sensor recognition changes
suddenly when passing over a
speed bump
The vehicle in front is moving verti- cally to the driving direction

- Driving on a curve
The FCA performance decreases
while driving on a curve. The FCA
may not recognize the vehicle in front
even in the same lane. It may unnec-
essarily produce the warning mes-
sage and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
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. 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, take a look around the vehi-
cle for your safety.
- Driving on a slope
The FCA performance decreases
while driving upward or downward on
a slope, not recognizing 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 mes-
sage 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.

- There is an item similar to a per- son’s body structure.
- The pedestrian is small.
- The pedestrian has impaired mobility.
- It is difficult to distinguish the pedestrian from the surroundings.
- The sensor recognition is limited. - There is a group of pedestrians.
- If a sudden change in the sensor
recognition takes place while pass-
ing through the speed bump.
- When the vehicle is severely shak- en.
- When driving around circular inter- section after the vehicle in front.
- If the front of the camera lens is contaminated by front glass tinting,
film, water repellent coating, dam-
age on glass, foreign matter (stick-
er, insect, etc.)
- The radar or camera or camera lens is damaged.
- If the headlights of the vehicle are not used at night or in the tunnel
section, or the light is too weak.
- If street light or the light of the vehi- cle coming from the opposite is
reflected or when sunlight is
reflected by the water on the road
surface. - When the back light is projected in
the direction of the vehicle's motion
(including the headlights of vehi-
cles).
- Road sign, shadow on the road, tunnel entrance, toll gate, partial
pavement.
- If the windshield has moisture on its surface or if windshield freezes.-
Driving in the fog.
- When objects are out of the sens- ing range of the sensor or radar.
- When the cyclist in front is riding intersected with the driving direc-
tion.
- When there is any other electro- magnetic interference.
- When the construction area, rail or other metal object is near the
cyclist.

Auto Hold and smart cruise control
is operating the Auto Hold will be
released regardless of accelerator
pedal operation and the vehicle will
start to move. The AUTO HOLD
indicator changes from green to

(Electronic Parking Brake))Radar to detect distance to the
vehicle ahead
The sensor detects the distance to
the vehicle ahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to

To adjust the sensitivity of
smart cruise control
The sensitivity of vehicle speed when
following the front vehicle to maintain
the set distance can be adjusted. Go
to the User Settings Mode (Driver
Assistance) and select (SCC
Reaction). You may select one of the
three stages you prefer.
Slow:
Vehicle speed to the vehicle ahead
to maintain the set distance is
slower than normal speed.
Normal: Vehicle speed to the vehicle ahead
to maintain the set distance is nor-
mal
Fast: Vehicle speed to the vehicle ahead
to maintain the set distance is
faster than normal speed.
✽ ✽ NOTICE
The last selected mode remains in
the system.(Continued)
Do not damage the sensor or sensor area by a strongimpact. If the sensor movesslightly off position, the smartcruise control system will notoperate correctly without anywarning or indicator from thecluster. If this occurs, takeyour vehicle to an authorizedKia dealer and have the sys-tem checked.
Use only a genuine Kia sensor cover for your vehicle. Do notpaint anything on the sensorcover.
If the front bumper becomes damaged in the area aroundthe radar sensor, the SmartCruise Control System maynot operate properly.

Vehicle recognition
Some vehicles ahead in your lane
cannot be recognized by the sensor
as follows:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profiles such as trailers with no loads A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
trunk(tailgate)
- While making turns by steering
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Adjust your vehicle speed by
depressing the brake pedal accord-
ing to the road condition ahead and
driving condition. When vehicles are at a standstill
and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not immedi-
ately recognize the stopped vehicle
in front of you.
In this case, you must maintain a
safe braking distance, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
