Function description
BCW uses radar sensors in the rear
bumper to monitor and warn the driv-
er of an approaching vehicle in the
driver's blind spot area.
1) Blind-Spot Area
It warns by detecting the vehicles in
the blind spots.
The blind spot detection range varies
relative to vehicle speed.
Note that if your vehicle is traveling
much faster than the vehicles around
you, the warning will not occur.2) Closing at high speed
BCW feature will warn you when a
vehicle is approaching in an adjacent
lane at a high rate of speed. If the
driver activates the turn signal when
the function detects an oncoming
vehicle, the function sounds an audi-
ble warning.
BLIND-SPOT COLLISION WARNING (BCW) (IF EQUIPPED)
OSK3058089L
OSK3058090L
WARNING
BCW is a supplemental func-
tion to assist you. Do not
entirely rely on the function.
Always pay attention, while
driving, for your safety.
Always be aware of road con-
ditions while driving and be
warn for unexpected situa-
tions even though BCW is
operating.
BCW is not a substitute for
proper and safe driving.
Always drive safely and use
caution when changing lanes
or backing up the vehicle.
BCW may not detect every
object alongside the vehicle.

Detecting Sensor
The rear corner radars are the sen-
sors inside the rear bumper for
detecting the side/rear areas. Always
keep the rear bumper clean for prop-
er operation of the function.
CAUTION
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
the warning light on the out-
side rearview mirror illumi-
nates or there is a warning
alarm.
Playing the vehicle audio sys-
tem at high volume may offset
Blind-Spot Collision Warning
warning sounds.
The warning of the Blind-Spot
Collision Warning may not
sound while other system's
warning sounds.
ODEP059158
■Rear corner radarsCAUTION
The function may not work
properly when the bumper has
been damaged, or if the rear
bumper has been replaced or
repaired.
The sensing range differs some-
what according to the width of
the road. When the road is nar-
row, the function may detect
other vehicles in the next lane.
The function may turn off due to
strong electromagnetic waves.
Always keep the sensor or near
the sensor clean.
NEVER arbitrarily disassem-
ble the sensor component nor
apply any impact on the sen-
sor component.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the function
may not operate correctly. In
this case, a warning message
may not be displayed.

Warning message
Blind-Spot Collision Warning (BCW)
system disabled. Radar blocked
This warning message may appear
when :
- One or both of the sensors on the
rear bumper is blocked by dirt or
snow or a foreign object.
- Driving in rural areas where the
sensor does not detect another
vehicle for an extended period of
time.
- When there is inclement weather
such as heavy snow or rain.If any of these conditions occur, the
light on the Blind-Spot Safety button
and the function will turn off automat-
ically.
Turn off BCW (if equipped) when a
trailer or carrier is installed.
- Press the Blind-Spot Safety button
(the indicator on the button extin-
guish) or “User Settings Driver
Assistance Blind-Spot Safety 
Off ”.
- Deactivate RCCW by deselecting
“User Settings Driver Assistance
Blind-Spot Safety Rear Cross-
Traffic Safety”.
If you use BCW, remove a trailer or
carrier.
When BCW canceled warning mes-
sage is displayed in the cluster,
check to make sure that the rear
bumper is free from any dirt or snow
in the areas where the sensor is
located. Remove any dirt, snow, or
foreign material that could interfere
with the radar sensors.
(Continued)
Have the vehicle inspected by
an authorized Kia dealer.
Do not apply foreign objects
such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the
sensor area. Doing so may
adversely affect the perform-
ance of the sensor.
NEVER install any acces-
sories or stickers on the front
windshield, nor tint the front
windshield.
Pay extreme caution to keep
the camera sensor out of water.
NEVER locate any reflective
objects (i.e. white paper, mir-
ror) over the crash pad. Any
light reflection may cause a
malfunction of the function.

Driving your vehicle
After any dirt or debris is removed,
BCW should operate normally after
about 10 minutes of driving the vehi-
cle.
If the function still does not operate
normally, have your vehicle inspect-
ed by an authorized Kia dealer.
Check Blind-Spot Collision Warning
system
If there is a problem with BCW, a
warning message will appear and the
light on the switch will turn off. The
function will turn off automatically. We
recommend that you have your vehi-
cle inspected by an authorized Kia
dealer.Limitations of the function

below situations, because the func-
tion may not detect other vehicles or
objects in certain circumstances.
When a trailer or carrier is installed.
The vehicle drives in inclement
weather such as heavy rain or
snow.
The sensor is polluted with rain,
snow, mud, etc.
The rear bumper where the sensor
is located is covered with a foreign
object such as a bumper sticker, a
bumper guard, a bike rack, etc.
The rear bumper is damaged, or
the sensor is out of the original
default position.
The vehicle height gets lower or
higher due to heavy loading in a
liftgate, abnormal tire pressure,
etc.

NOTICE
Driver Attention Warning utilizes
the front view camera sensor on the
front windshield for its operation.
To keep the front view camera
sensor in the best condition, you
should observe the followings:
- Do not disassemble camera tem-
porarily for tinted window or
attaching any types of coatings and
accessories. If you disassemble a
camera and assemble it again, take
your vehicle to an authorized Kia
dealer and have the system
checked.
- Do not locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a mal-func-
tion of Driver Attention Warning.
(Continued)(Continued)
- Pay extreme caution to keep the
front view camera out of water.
- Do not arbitrarily disassemble the
camera assembly, nor apply any
impact on the camera assembly.
• Playing the vehicle audio system
at high volume may offset Driver
Attention Warning warning
sounds.
For more information of front
view camera, refer to “Lane
Keeping Assist (LKA)”.CAUTION
Driver Attention Warning may
not properly operate with limit-
ed alerting in the following situ-
ations:
The function will not operate
for about 15 seconds when
restarting the engine or initial-
izing the front view camera
such as rebooting, etc.

Detecting Sensor (front view
camera/front radar)
Front view camera
Front view camera is a sensor for
detecting lanes and the front vehi-
cles.
If the sensor is covered with dirt,
snow or other foreign matter, the
sensor’s detection performance will
be degraded and SCC will be tem-
porarily cancelled so that it does not
properly work.Always keep the area in front of the
sensor clean.
For more information of front view
camera, refer to "Lane Keeping
Assist (LKA)"
Front radar
Front radar detects the distance to
the vehicle ahead.
If the sensor or sensor cover is cov-
ered with dirt, snow or other foreign
matter, the sensor’s detection per-
formance will be degraded and SCC
will be temporarily cancelled so that
it does not properly work.
Always keep the area in front of the
sensor clean.ODEP059029
