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)

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

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.

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

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-
