WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To help avoid accidents, do not focus
only on the warning light and neglect
to see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning alarm.
• Playing the vehicle audio system at
high volume may offset the Blind-
Spot Collision Warning system
warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning sounds. Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
wheel, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.

WARNING
• The driver is responsible for accurate
steering.
• Do not unnecessarily operate the
steering wheel, when Blind-Spot
Collision-Avoidance Assist system is
in operation.
• Always pay extreme caution while
driving. The Blind-Spot Collision-
Avoidance Assist system may not
operate or unnecessarily operate
in accordance with your driving
situations.
• Blind-Spot Collision-Avoidance
Assist system is not a substitute
for safe driving practices, but a
convenience function only. It is
the responsibility of the driver to
always drive cautiously to prevent
unexpected and sudden situations
from occurring. Pay attention to the
road conditions at all times.Detecting Sensors
(Front view camera and Rear
corner radar)
„„Front view camera
ODN8A069024
„„Rear corner radars
ODN8069031L
Front view camera
The front view camera is a sensor
detecting the lane. If the sensors are
covered with snow, rain or foreign
substance, the system may temporarily
be cancelled and not work properly
until the system is cancelled due to the
degradation of the sensor’s detection
performance. Always keep the sensor clean.  Refer to Lane Keeping Assist (LKA) for
cautions for the front view camera.

06
6-83
Rear corner radar
The rear corner radars are the sensors
inside the rear bumper for detecting the
side and rear areas. Always keep the rear
bumper clean for proper operation of the
system.
CAUTION
• 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 somewhat
according to the width of the road.
When the road is narrow, the system
may detect other vehicles in the next
lane. On the other hand, when the
road is wide, the system may not
detect vehicles on both lanes and
may not warn.
• The system may turn off due to
strong electromagnetic waves.
• Always keep the sensors clean.
• NEVER arbitrarily disassemble the
sensor component nor apply any
impact on the sensor component.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, the system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
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 performance of
the sensor.
• NEVER install any accessories or
stickers on the front windshield, nor
tint the front windshield.
• Pay extreme caution to keep the
front view camera out of water.
• NEVER locate any reflective objects
(i.e. white paper, mirror) over the
crash pad. Any light reflection may
cause a malfunction of the system.

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.
- A trailer or carrier or another object is installed around the rear view radars.
If any of these conditions occur, the
system will turn off automatically.
When BCW canceled warning message
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
sensors are located. Remove any dirt,
snow, or foreign material that could
interfere with the radar sensors.
After any dirt or debris is removed, the
system should operate normally after
about 10 minutes of driving the vehicle.
If the system still does not operate
normally have your vehicle inspected by
an authorized HYUNDAI dealer.
Information
Turn off BCW, BCA and RCCW, RCCA
system (if equipped) when a trailer or
carrier is installed. - Deactivate BCW, BCA system by

are 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 trunk,
abnormal tire pressure, etc.
• When the temperature of the rear bumper is high.
• When the sensors are blocked by
other vehicles, walls or parking-lot
pillars.
• The vehicle drives on a curved road.
• The vehicle drives through a tollgate.
• The road pavement (or the peripheral
ground) abnormally contains metallic
