correctly without any warning
or indicator from the cluster.
If this occurs, have your vehi-
cle checked by an authorized
Kia dealer as soon as possi-
ble.
Use only a genuine Kia sensor
cover for your vehicle. Do not
paint anything on the sensor
cover.
If the front bumper becomes
damaged in the area around
the radar sensor, Smart Cruise
Control may not operate prop-
erly.
(Continued)(Continued)
To prevent sensor cover dam-
age from occurring, wash the
car with a soft cloth.
Do not tint the window or
install stickers, accessories
around the inside mirror
where the camera is installed.
Make sure the frontal camera
installation point does not get
wet.

Your vehicle speed can be reduced
due to a vehicle in the adjacent
lane. Adjust your vehicle speed by
depressing the brake pedal
according to the road condition
ahead and driving condition. Apply
the accelerator pedal and select
the appropriate set speed. Check
to be sure that the road conditions
permit safe operation of Smart
Cruise Control.
On inclines
During uphill or downhill driving,
Smart Cruise Control may not
detect a moving vehicle in your
lane, and cause your vehicle to
accelerate to the set speed. Also,
the vehicle speed will rapidly down
when the vehicle ahead is recog-
nized suddenly.
Select the appropriate set speed
on inclines and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road condition ahead and driving
condition.
Lane changing
A vehicle which moves into your
lane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme-
diately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a vehicle which moves into your
lane is slower than your vehicle,
your speed may decrease to main-
tain the distance to the vehicle
ahead.

Driving your vehicle
If a vehicle which moves into your
lane is faster than your vehicle,
your vehicle will accelerate to the
selected speed.
Your vehicle may accelerate when
a vehicle ahead of you disappears.
When you are warned that the
vehicle ahead of you is not detect-
ed, drive with caution.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
liftgate (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 recognize
the stopped vehicle 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. Always look out for pedestrian
when your vehicle is maintaining a
distance with the vehicle ahead.

located. Remove any dirt, snow, or
foreign material that could interfere
with the radar sensors.
After any dirt or debris is removed,
BCW should operate normally after
about 10 minutes of driving the vehi-
cle.
If the function does not work normal-
ly even though the foreign sub-
stance, trailer or carrier, or other
