Limitations of the System
The Forward Collision Avoidance Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian or cyclists on the roadway
through radar signals and camera
recognition to warn the driver that acollision is imminent, and if neces-
sary, apply emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle, a pedestrian or
cyclists ahead. In these cases, the
FCA system may not operate nor-
mally. The driver must pay careful
attention in the following situations
where the FCA operation may belimited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a deadend street).
The FCA system cannot
detect the cross traffic cyclist
that are approaching.
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress thebrake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to detect vehicles, pedes-
trian or cyclist in front of the
vehicle.
The FCA system operates
only to detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not designed to detect other
objects on the road such asanimals.
The FCA system does not
detect vehicles in the oppo-
site lane.

Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front view camera or front radar
sensor recognition system may not
detect the vehicle, pedestrian or
cyclist traveling in front on a curvedroad.
This may result in no alarm and brak-
ing when necessary. Always pay
attention to road and driving condi-
tions, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance.Forward Collision-Avoidance Assist
system may recognize in the next
lane or outside the lane when driving

- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians orcyclists
The sensor may be limited when:
The pedestrian or cyclist is not fully detected by the camera recogni-
tion system, for example, if the
pedestrian is leaning over or is not
fully walking upright
The pedestrian or cyclist is moving very quickly or appears abruptly in
the camera detection area
The pedestrian or cyclist is wear- ing clothing that easily blends into
the background, making it difficult
to be detected by the camerarecognition system
The outside lighting is too bright (e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural roadat night)
It is difficult to detect and distin- guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclist or a large
crowd There is an item similar to a per-
son's body structure
The pedestrian or cyclist is small
The pedestrian has impaired mobility
The sensor recognition is limited
The radar sensor or camera is blocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera

System Description
Blind-Spot Collision Warning(BCW)
The Blind-Spot Collision Warning
(BCA) 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
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
The Lane Change Assist feature will
alert you when a vehicle is approach-
ing 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 (BCA)
The Blind-Spot Collision-AvoidanceAssist (BCA) system detects the
front lane through the camerainstalled on the upper front wind-shield and detects the side/rear
areas through radar sensors.
The Blind-Spot Collision-Avoidance
Assist system may activate theElectronic Stability Control (ESC) inaccordance with a colliding possibili-
ty with an approaching vehicle while
changing lanes. It is to lower the col-
liding risk or mitigate the colliding
damage.

Blind-Spot Collision-Avoidance Assist (BCA) system is automatically deacti-
vated when:
- The vehicle drives a certain dis-tance 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 prop-
erly control your vehicle in accor-
dance with driving situations. Thus,
always pay close attention to road
situations.Detecting Sensor
(Front View Camera and RearCorner Radar)
The driver is responsible for accurate steering.
Do not unnecessarily operate
the steering wheel, when the
Blind-Spot Collision-AvoidanceAssist 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 drivingsituations.
The Blind-Spot Collision-
Avoidance Assist system is
not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is theresponsibility of the driver to
always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. Pay attention to the roadconditions at all times.

Front view camera
The front camera is a sensor detect-
ing the lane. If the sensor is covered
with snow, rain or foreign substance,
the system may temporarily be can-
celed. The system is canceled due to
the degradation of the sensor's
detection performance. Always keepthe sensor clean.
* Refer to Lane Keeping Assist(LKA) System for cautions for the
front camera sensor.
Rear corner radar
The rear 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.
The system may not work
properly when the bumper
has been damaged, or if the
rear bumper has beenreplaced 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.
The system may turn off due
to strong electromagnetic
waves.
Always keep the sensors
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. 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 perform-
ance of the sensor.
NEVER install any acces-
sories or stickers on the front
windshield, nor tint the frontwindshield.
Pay extreme caution to keep the camera sensor out of
water.
NEVER locate any reflective
objects (i.e. white paper, mir-
ror) over the crash pad. Any
light reflection may cause amalfunction of the system.
