Limitations of the system
FCA-Junction Turning function is only a
supplemental system for driver’s safety
whilst turning left on the crossroads. The
driver should hold the responsibility to
control the vehicle. The system monitors
the oncoming vehicle ahead the road
through the front view camera and
radar. In certain situations, the front view
camera and radar may not be able to
detect the oncoming vehicles properly.
The driver must pay careful attention
in the following situations where the
system operation may be limited or it
may activate unintentionally.
The sensor may be limited when:
• The radar sensor or camera r
ecognizes the approaching vehicle
too late.
• The radar sensor or camera is blocked with a foreign object or debris.
• The driving direction of the approaching vehicle is irregular or
frontal.
• The approaching vehicle changes lanes too late or decelerates suddenly.
• The angle of the approaching vehicle is out of range.
• Whilst circling, the sensor (the front view camera or front radar) does not
detect the approaching vehicle.
• The driving speed of the approaching vehicle is too fast or slow.
• The head lamps of the approaching vehicle are turned off or asymmetrical. • The approaching vehicle stops whilst
turning left.
• The vehicle moves out of its lane or returns to its lane.
• The vehicle changes lanes suddenly at a low speed whilst there is an
approaching vehicle.
• The brightness outside is too so it does not detect the vehicle.
• Inclement weather such as heavy rain or snow obscures the field of view of
the front view camera or front radar.
• The approaching vehicle is covered with snow.
• The field of view in front is obstructed by sun glare.
• The shape of approaching vehicle is unusual.
• Whilst driving upward or downward on a slope.

rarely controls the steering wheel, when
the vehicle drives well inside the lanes.
However, it starts to control the steering
wheel, when the vehicle is about to
deviate out of the lanes.
Lane Departure Warning
LDW alerts the driver with a visual
warning and a warning alarm when the
system detects the vehicle departing
the lane. The steering wheel will not be
controlled.

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.

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.
