Avoidance Assist system
• When FCA is not working properly,
the FCA warning light ( ) will illu-
minate and the warning message
will appear for a few seconds. After
the message disappears, the mas-
ter warning light ( ) will illumi-
nate. In this case, have the vehicle
inspected by an authorized retailer
of Genesis Branded products.
• The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light. Both FCA
warning light and warning mes-
sage will disappear once the ESC
warning light issue is resolved.

• FCA is only a supplemental
system for the driver's con-
venience. It is the driver's
responsibility to control the
vehicle operation. Do not
solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed or to stop the vehicle.
WARNING
• In certain instances and
under certain driving condi-
tions, the FCA system may
produce a warning alarm and
control the brake system
unnecessarily. And, the FCA
system may not produce a
warning alarm and control the
brake system due to detecting
limitation of sensor.
Also due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclist ahead. The FCA sys-
tem may not activate and the
warning message may not be
displayed.
• Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
• If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
• The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
• The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid collision.

Limitations of the System
The Forward Collision-Avoidance
Assist system is designed to monitor
the vehicle ahead or a pedestrian or
cyclist in the roadway through radar
signals and camera recognition to
warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sensor
or the camera may not be able to
detect the vehicle, pedestrian or
cyclist 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 be
limited.
Detecting vehicles
The sensor may be limited when:
• The system may not operate for 15
seconds after the engine is started
or the camera is initialized
• The radar sensor or camera is cov-
ered with a foreign object or debris
• The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
• 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
• There is severe irregular reflection
from the radar sensor
• The radar/camera sensor recogni-
tion is limited
• The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.) • 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 as
animals.
• The FCA system does not
detect vehicles in the oppo-
site lane.
• The FCA system does not
detect cross traffic vehicles
that are approaching.
• The FCA system cannot
detect cross traffic cyclists
that are approaching.
• The FCA system cannot
detect vehicles that are
stopped vertically to your
vehicle at a intersection or
dead end street.
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance or to stop the
vehicle.
WARNING
• The brake control may not
work, possibly causing a colli-
sion, if a vehicle in front
abruptly stops. Always pay
extreme caution.
• Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
• The FCA system operates
only when the system detect
vehicles, pedestrian or cyclist
in front of the vehicle.

Driving your vehicle
• The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
• The camera's field of view is not
well illuminated (either too dark or
too much reflection or too much
backlight that obscures the field of
view)
• The vehicle in front does not have
their rear lights properly turned ON
or their rear lights are located
unusually
• The outside brightness changes
suddenly, for example when enter-
ing or exiting a tunnel
• Light coming from a street light or
an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
• The field of view in front is obstruct-
ed by sun glare
• The windshield glass is fogged up;
a clear view of the road is obstruct-
ed
• The vehicle in front is driving errati-
cally
• The vehicle is on unpaved or
uneven rough surfaces, or road
with sudden gradient changes
• The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.
• The vehicle drives inside a building,
such as a basement parking lot
• The camera does not recognize
the entire vehicle in front
• The camera is damaged• The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel
• The shadow is on the road by a
median strip, trees, etc.
• The vehicle drives through a toll-
gate.
• The rear part of the vehicle in front
is not normally visible (the vehicle
turns in other direction or the vehi-
cle is overturned.)
• The adverse road conditions cause
excessive vehicle vibrations while
driving
• The sensor recognition changes
suddenly when passing over a
speed bump
• The vehicle in front is moving verti-
cally to the driving direction
• The vehicle in front is stopped ver-
tically
• The vehicle in front is driving
towards your vehicle or reversing
• You are on a roundabout and the
vehicle in front circles

• Driving on a curve
The performance of Forward
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, pedes-
trian or cyclist traveling in front on
a curved road.
This may result in no alarm and
braking when necessary. Always
pay attention to road and driving
conditions, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.Forward Collision-Avoidance Assist
system may recognize a vehicle or
pedestrian or cyclist in the next lane
or outside the lane when driving on a
curved road.
If this occurs, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving.

Driving your vehicle
• Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope.
The front view camera or front
radar sensor recognition may not
detect the vehicle, pedestrian or
cyclist in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the system suddenly recog-
nizes the vehicle, pedestrian or
cyclist in front while passing over a
slope, you may experience sharp
deceleration. Always keep your
eyes forward while driving upward
or downward on a slope, and, if
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain distance.• Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may
not immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.
When driving in stop-and-go traffic,
and a vehicle in front of you
merges out of the lane, the FCA
system may not immediately
detect the new vehicle that is now
in front of you. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.

• 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, additional special atten-
tion 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 necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.
Detecting pedestrians or
cyclists
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 camera
recognition 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 road
at 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 is small
• The pedestrian has impaired mobil-
ity
• The sensor recognition is limited
• The radar sensor or camera is cov-
ered with a foreign object or debris
• The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or

System Description
Blind-Spot Collision Warning
(BCW)
The Blind-Spot Collision Warning
system uses radar sensors in the
rear bumper to monitor and warn the
driver when it detects an approach-
ing 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 it detects a vehicle is
approaching in an adjacent lane at a
high rate of speed. If the driver acti-
vates the turn signal when the sys-
tem detects an oncoming vehicle, the
system sounds an audible alert.
Blind-Spot Collision-Avoidance
Assist (BCA)
The Blind-Spot Collision-Avoidance
Assist system helps detect the front
lane through the camera installed on
the upper front windshield and helps
detect the side/rear areas through
radar sensors.

Detecting Sensor
(Camera and Radar)
Front camera
The front camera function as a sen-
sor detecting the lane. If the sensor is
covered with snow, rain or foreign
substance, the system may tem-
porarily be canceled and not work
properly. Always keep the sensor
clean.
Refer to Lane Keeping Assist
System for cautions for the front
camera sensor.
Rear radar
The rear radars are located inside
the rear bumper for detecting the
side and rear areas. Always keep the
rear bumper clean for proper opera-
tion of the system.• The system may not work prop-
erly when the bumper has been
damaged, or if the rear bumper
has been replaced or repaired.
• The sensing range differs some-
what according to the width of
the road. When the road is nar-
row, the system may detect
other vehicles in the next lane.
• The system may turn off if inter-
fered by electromagnetic waves.
• Always keep the sensors clean.
• NEVER disassemble the sensor
component or apply any impact
on the sensor component.
• Be careful not to apply unneces-
sary 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
retailer of Genesis Branded
products.
• Do not apply foreign objects
such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the sen-
sor area. Doing so may adverse-
ly affect the performance of the
sensor.
• NEVER install any accessories
or stickers on the front wind-
shield, or tint the front wind-
shield.
• Pay extreme caution to keep the
camera sensor dry.
• NEVER place any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may prevent the sys-
tem from functioning properly.
