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-spo
t vehicle warning
OIK057138
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)

F
ast approach vehicle warning
OIK057139L
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
ODN8H059322
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.
Detecting Sensors

corner radar)
•„Front view camera

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.

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.

Function malfunction and
limitations
Function malfunction
ODN8A070030When Safe Exit Assist is not working
properly, the ‘Check Blind-Spot Safety
system’ warning message will appear
on the cluster, and the system will turn
off automatically or the system will be
limited. We recommend that the system
be inspected by an authorized HYUNDAI
dealer.
Function disabled
OCN7070041L
When the rear bumper around the rear
corner radar or sensor is covered with
foreign material, such as snow or rain,
or installing a trailer or carrier, it can
reduce the detecting performance and
temporarily limit or disable Safe Exit
Assist.
If this occurs, the ‘Blind-Spot Safety
function disabled. Radar blocked’
warning message will appear on the
cluster.
The function will operate normally
when such foreign material or trailer,
etc. is removed, and then the engine is
restarted.
If the function does not operate normally
after it is removed, we recommend
that the system be inspected by an
authorized HYUNDAI dealer.
