2021 GENESIS G90 Owner's Manual

Prerequisite for activation
The FCA system will activate when
'Active Assist' or 'Warning Only' under
Forward Safety is selected in the AVN
system screen, and when the follow-
ing prerequisites are satisfied.
• ESC (Electronic Stability Control)
is on.
• Vehicle speed is over 5 mph (8
km/h). (The FCA is only activated
within a certain speed range.)
• The system detects a pedestrian,
cyclist or a vehicle in front, which
may collide with your vehicle.
However, FCA may not be activat-
ed or may only sound a warning
alarm depending on the driving or
vehicle conditions.
FCA may not operate properly
according to the frontal situation or
the direction of a pedestrian or
cyclist.
FCA Warning Message and
Brake Control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk of
a frontal collision, such as when a
vehicle ahead suddenly brakes, or
the system detects that a collision
with a pedestrian or cyclist is immi-
nent.

• To avoid driver distractions,
do not attempt to set or can-
cel the FCA while driving the
vehicle. Always completely
stop the vehicle at a safe
place before setting or cancel-
ing the system.
• FCA automatically activates
upon placing the Engine
Start/Stop button to the ON or
START position. The driver
can deactivate FCA by cancel-
ing the system setting in the
AVN system screen.
• FCA automatically deacti-
vates upon canceling ESC.
When ESC is canceled, FCA
cannot be activated in the
AVN system screen. In this sit-
uation, the FCA warning light
will illuminate which is nor-
mal.
WARNING

Collision Warning (First warning)
• The warning message appears on
the cluster LCD display with a
warning chime. Additionally, some
vehicle system intervention occurs
by the engine management system
to help decelerate the vehicle.
• Your vehicle speed may decelerate
moderately.
• If FCA detects a vehicle in front,
the system operates when your
vehicle speed is between 5 mph (8
km/h) and 112 mph (180 km/h).
Maximum vehicle speed may
decrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
• If FCA detects a pedestrian or
cyclist in front, the system operates
when your vehicle speed is
between 5 mph (8 km/h) and 56
mph (90 km/h). Maximum vehicle
speed may decrease depending
on the condition of the pedestrian
ahead and surroundings.
• If you select 'Warning only' for the
system 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 will not control the
brake.
Emergency braking
(Second warning)
• The warning message appears on
the cluster LCD display with a
warning chime. Additionally, some
vehicle system intervention occurs
by the engine management system
to help decelerate the vehicle.
• The brake control is maximized
just before a collision, reducing
impact when it strikes a forward
vehicle.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is above 5 mph (8 km/h) and
47 mph (75 km/h) or under.
Maximum vehicle speed may
decrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
• If FCA detects a pedestrian or
cyclist in front, the system operates
when your vehicle speed is 5 mph
(8 km/h) or above and under 40
mph (65 km/h). Maximum vehicle
speed may decrease depending
on the condition of the pedestrian
ahead and surroundings.

• If you select 'Warning only' for the
system 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 braking
system 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.
5-55

• 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 sound
such as seat belt warning
chime is already generated, the
Forward Collision-Avoidance
Assist 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 vehi-
cle, pedestrian or cyclist (if
equipped) ahead, the speed of
the vehicle ahead, and the dri-
ver'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.
• Use only genuine parts to repair
or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover.

• 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

• 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.
