Driving on a curve
The performance of the FCA sys-
tem may be limited when driving on
a curved road.
On curved roads, the other vehicle
on the same lane is not recognized
and the FCA system's perform-
ance may be degraded. This may
result in unnecessary alarm or
braking or no alarm or braking
when necessary.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must
maintain a safe braking distance,
and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance. The FCA system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Check to be sure that the road condi-
tions permit safe operation of FCA.

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
The sensor may be limited when:
The pedestrian is not fully detectedby the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion 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 from other
objects in the surroundings, for
example, when there is a group of
pedestrians 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
stuck of foreign matter (sticker,
bug, etc.) on the glass

Driving your vehicle
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
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 obstructed by sun glare
The windshield glass is fogged up; a clear view of the road is obstruct-
ed
The adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump
You are on a roundabout
The pedestrian suddenly interrupts in front of the vehicle
There is any other electromagnetic interference
The construction area, rail or other metal object is near Do not use the Forward
Collision-Avoidance Assist
(FCA) system when towing a
vehicle. Application of the
FCA system while towing may
adversely affect the safety of
your vehicle or the towing
vehicle.
Use extreme caution when 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.
The FCA system is designed to help detect and monitor the
vehicle ahead or detect a
pedestrian in the roadway
through radar signals and
camera recognition. It is not
designed to detect motorcy-
cles, or smaller wheeled
objects such as luggage
bags, shopping carts, or
strollers.
Never try to test the operation of the FCA system. Doing so
may cause severe injury or
death.
If the front bumper, front glass, radar or camera have
been replaced or repaired,
have the vehicle inspected by
an authorized retailer of
Genesis Branded products.

This function is only a supple-
mental system and it is not
intended to, nor does it replace
the need for extreme care and
attention of the driver. The
sensing range and objects
detectable by the sensors are
limited. Pay attention to the
road conditions at all times.
Always drive cautiously to prevent accidents from any
unexpected or sudden situa-
tions. The function does not
steer the vehicle completely
and is not a collision avoid-
ance system.
WARNING
OHI058282L

Driving your vehicle
System Description
Blind-Spot Collision Warning(BCW)
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver when it detects 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 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 (BCA) system helps detect the
front lane through the camera
installed on the upper front wind-
shield 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 (LKA)
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.
