System description
BCW system uses radar sensors in
the rear bumper to monitor and warn
the driver 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 system feature will alert 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 system detects an oncom-
ing vehicle, the system sounds an
audible alert.

Always be aware of road con-
ditions while driving and be
alert for unexpected situa-
tions even though BCW sys-
tem is operating.

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 system.
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
system warning sounds.
The warning of the Blind-Spot
Collision Warning system may
not sound while other sys-
tem's warning sounds.
ODEP059158
■Rear corner radarsCAUTION
The system 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 system may detect
other vehicles in the next lane.
The system 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 system
may not operate correctly. In
this case, a warning message
may not be displayed.
