2020 GENESIS G90 Owner's Manual

If you select 'Warning only' for thesystem setting, the FCA system
activates and produces only warn-
ing alarms in accordance with the
collision risk levels. You should
control the brake directly because
the FCA system do not control the
brake.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat- ically canceled, when risk factors
disappear.

The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
After the brake control is acti- vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-
onds.
CAUTION
If any other warning soundsuch as seat belt warning
chime is already generated, the
Forward Collision-Avoidance
Assist (FCA) system warning
may not sound.
Playing the vehicle audio sys- tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.

FCA Sensor
(Front Radar/Front Camera)
In order for the FCA system to oper-
ate properly, always make sure the
sensor cover or sensor is clean and
free of dirt, snow, and debris.
Dirt, snow, or foreign substances on
the sensor cover or sensor may
adversely affect the sensing perform-
ance of the sensor. Do not apply license plate frame
or foreign objects such as a
bumper sticker or a bumper
guard near the radar sensor.
Doing so may adversely affect
the sensing performance of the
radar.
Always keep the radar sensor and cover clean and free of dirt
and debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
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 FCA system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
retailer of Genesis Branded
products.
If the front bumper becomes damaged in the area around the
radar sensor, the FCA system
may not operate properly. Have
the vehicle inspected by author-
ized retailer of Genesis Branded
products.

FCA is only a supplementalsystem 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 andunder 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 or pedestri-
an ahead. The FCA system
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 (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian in the roadway through
radar signals and camera recogni-
tion 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 or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. 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 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 be insufficient, possibly causing
a collision, 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 or pedestrian in front
of the vehicle.

5-60
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 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.

Driving your vehicle
Driving on a slope The performance of the FCA
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane. It may unnecessarily produce
the warning message and the warn-
ing alarm, or it may not produce the
warning message and the warning
alarm at all.
When the FCA suddenly recog-
nizes the vehicle 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 vehi-
cle that is now in front of you. In this
case, you must maintain a safe brak-
ing distance, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain a safe distance.
