These sensors detect frontal vehicles,
pedestrian and cyclist.
In order for FCA system to operate
properly, always make sure the sensor
cover or sensor is clean and free of dirt,
snow, and debris.
Dirt, snow, or foreign substances on the
sensor cover or sensor may adversely
affect the sensing performance of the
sensor. Always keep these clean.
 Refer to “Lane Keeping Assist (LKA)” for cautions for the front camera.
NOTICE
• Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
cover clean and free of dirt and
debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, FCA system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, FCA system may not
operate properly. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• Use only genuine parts to repair or
replace a damaged sensor or sensor
cover. Do not apply paint to the
sensor cover.

System Description
Blind-Spot Collision Warning
Blind-Spot Collision Warning system
uses rear corner radar sensors to monitor
and warn the driver of an approaching
vehicle in the driver’s blind spot area.
(1) Blind-spot vehicle warning
OIK057138OIK057138
BCW system detects and warns vehicles
in blind-spot.
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) Fast approach vehicle warning
OIK057139LOIK057139L
BCW system will alert you when a vehicle
is detected approaching in an adjacent
lane at a high rate of speed. If the driver
activates the turn signal when the system
detects an oncoming vehicle, the system
sounds an audible alert.
Blind-Spot Collision-Avoidance
Assist
ODN8H059322ODN8H059322
Blind-Spot Collision-Avoidance Assist
system detects the front lane through the
front view camera installed on the upper
front windshield and detects the side/
rear areas through rear corner radars.

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.

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.

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.

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.

Front radar
The front radar is a sensor detecting
v
ehicles in front and maintains the
distance between them. 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.
CAUTION
•
Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
lens cover clean and free of dirt and
debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,
Smart Cruise Control system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, Smart Cruise Control
system may not operate properly.
