GENESIS G90 2021 Owner's Manual

When certain conditions are met, the
engine is automatically decoupled
from the transmission while the shift
lever is remained in D (Drive). In this
Coasting mode, the engine stays at
idling speed to reduce fuel consump-
tion and increase coasting distance.
Coasting Setting
The Coasting function must be
turned ON from the Settings menu in
the AVN system screen. Select:
- Setup →Vehicle Settings →Drive
Mode →Coasting
For detailed information, scan the
QR code in a separately supplied
simple manual.
When Coasting is turned ON and the
conditions are met, the function
operates with a "Coasting" message
illuminated at the top center of the
instrument cluster.
• If the accelerator pedal is
pressed quickly for accelerating
with the Coasting function in
operation, acceleration may
occur after the engagement of
the clutch inside the transmis-
sion. In turn, the driver may con-
tinue to feel acceleration even
after the system is turned off.
• Driving with the Coasting func-
tion off may be required in some
cases since the engine brake is
not applied while the Coasting
function is in operation.
• Operating the AVN system
screen to activate or deactivate
the Coasting function while driv-
ing may be dangerous as the dri-
ver's attention is dispersed.

The Forward Collision-Avoidance
Assist system is designed to help
detect and monitor the vehicle ahead
or help detect 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.System Setting and Operation

Take the following precautions
when using the Forward
Collision-Avoidance Assist
system:
• This system 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 driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at all
times.
• Drive at posted speed limits
and accordance to road con-
ditions.
• Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. The Forward Collision-
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.
WARNING

• The warning light illu-
minates on the instru-
ment cluster, when you
cancel the FCA system.
The driver can monitor the FCA
ON/OFF status in the instrument
cluster. Also, the warning light illu-
minates when the ESC (Electronic
Stability Control) is turned off. If the
warning light remains ON when the
FCA is activated, have the system
checked by an authorized retailer
of Genesis Branded products.
• Selecting Warning Timing
The diver can select the initial
warning activation time from the
Settings menu in the AVN system
screen. Select:
- Setup →Vehicle Settings →
Driver Assistance →Warning
Timing →Normal / Late
For detailed information, scan
the QR code in a separately sup-
plied simple manual.The options for the initial Forward
Collision Warning includes the fol-
lowing:
- Normal:
When this option is selected, the
initial Forward Collision Warning is
activated sensitively. If you feel the
warning activates too early, set the
Forward Collision Warning to
'Late'.
Even though, 'Normal' is selected if
the front vehicle suddenly stops
the initial warning activation time
may not seem fast.
- Late:
When this option is selected, the
initial Forward Collision Warning is
activated later than normal. This
setting reduces the amount of dis-
tance between the vehicle, pedes-
trian or cyclist (if equipped) ahead
before the initial warning occurs.
Select 'Late' when traffic is light
and when driving speed is slow.
When you accelerate suddenly to
the vehicle ahead, the warning
may seem to activate earlier even if
'Late' is selected.
Information
If you change the warning timing, the
warning time of other systems may
change.

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.
5-53

• 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
05
• 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 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.
